    There was a time where HRE Wheels were the most desireable wheels on the market. They had an unbeatable combination of looks, pricing, and performance. Along the way something happened and HRE has moved away from performance and focused more on profit margins. Their new RS2M and RS3M series of wheels retail for $2100 per rim. Why? What justifies that price tag? Are they lightweight? No. Do the have some sort of technologically advanced materials? No. Do they offer a new or stunning design? No. Frankly, you would be hard pressed to tell this is a new wheel line unless HRE told you. Here is what HRE's president had to say about them. Translation: We ran out of ideas and this is a cheap way to reintroduce our same old tired designs at a premium. As a matter of fact, I remember those lines of his on a previous wheel line introduction. He is using the same lines from a 2015 wheel release: HRE's president then: They rearrange a few words, use the same basic press release, and here we are with a 'new' $2100 per wheel line. When was the last time HRE actually was innovative? Why aren't they offering high performance and lightweight composite rims for some of their exorbitant prices? Do not think BoostAddict has some axe to grind here as the M3 wears HRE wheels. The thing is, when the HRE C90 wheels were purchased eight years ago they were chosen because they were the lightest on the market offering a great blend of performance, strength, weight, looks, and cost. HRE does not even bother to include what the rims weigh any longer. What happened to the performance aspect? It seems to have taken a similar tumble as their customer service. HRE just seems to be all about squeezing out every last dime by recycling as many tired designs as they can. This is stuff we have all seen before except now we get a higher price tag along with absolutely no performance benefit. BoostAddict was shocked when inquiring about current HRE wheel weights. They haven't gotten lighter, that is for sure. This article will not change anything nor will any words written by anyone as HRE is a juggernaut and too big to care. However, many enthusiasts do care how they spend their money and this one in particular is going to look elsewhere for a set of performance rims.

    My father is responsible for my love of cars. I just alway remember him having a German car of some sort in the garage. Whether it was an old air-cooled 911, a Mercedes S-Class, a Mercedes SL, whatever, he would always choose a German car over an American car. Well, not always. Just since I was born. When he came to this country in the 70's American cars were on a downward swing. His first car was a Nova SS. It quickly became his second car after numerous problems. An Oldsmobile he can't or more accurately doesn't want to remember followed. A Cadillac Eldorado quickly replaced it and he liked the Cadillac but my mother drove it through the front of a store and that was the end of that. An unbroken string of German cars to this day followed. My first car was a German vehicle, a BMW E46 330i. My father would not even entertain the idea of an American car. If I wanted a car, it was a BMW 3-Series or nothing else. Rough, I know. He showed up with a brand new E46 330i one day after school and that was the end of that. My love for BMW started with that car and continued for quite a while. The BMW M car was in my opinion the absolute best all around vehicle in the world. I confirmed this assertion when I traded the E46 330i in on a BMW E46 M3. You remember your first love? The E46 M3 was mine. You never quite fall in love like that again. The 2017 911 Carrera gets close though. I considered a Z06 and a Viper over the 911 but the 911 is best for business. That business aspect is why I'm currently driving the C7 Z06 that belongs to BMS (Burger Tuning). Hey, $100k+ cars don't exactly pay for themselves. I admit the Z06 was in the back of my mind when buying the Porsche and considering the price range yes, you can cross shop them. It goes without saying the Z06 has more power. The LT4 6.2 liter supercharged V8 offers 650 horsepower and 650 lb-ft of torque. The 9A2B6 3.0 liter flat-6 the 991.2 Carrera uses is less than half the size. It has 'only' 370 horses (underrated horses) but the turbo punch is substantial and the car runs 11's stock. It still trails the Z06 by over a second in the 1/4 mile though and 14+ miles per hour of trap speed. That is a big difference. Especially considering the example I sampled has a tune, pulley, and intake. It makes 585 rear wheel horsepower or about 200 more than my Carrera. Not to mention, a lot more torque that comes on like a light switch being flipped. That may sound great but it is actually part of the problem with the Z06. It constantly wants to remind you of its motor. It is dominated by it. It gets to the point where it can become tiring as well as scary when traction is easily lost. When I picked up the car on the first first turn when I applied the throttle the traction control light came on and I got wheelspin. I was just trying to make a left turn out of a neighborhood, not light the tires up. That is the kind of power the Z06 has. You have to respect it but what is the point if you can't use it? Want to mash the throttle in the Z06? Make sure you are in second gear, point it straight, and hang on. If you are at a high enough speed it will hook and go. If you aren't, you'll spin the tires even in second. If you add even more torque to it just change the point straight in second gear recipe to point it straight in third gear before mashing the gas. The acceleration is amazing though. Oh boy, it's fast. Definitely faster than the Porsche. The Porsche can use its first gear though. It can even use it from a stop. It can go full throttle from a stop. As a matter of fact, if these two lined up at a light the Porsche would be in a different zip code by the time the Z06 got traction. The Porsche makes complete use of every horse at any time. The Z06 doesn't. It can't. What it can do is remind you there is a ton of torque available in any gear. In the 911 you need to be above 3000 rpm to feel that rush of torque. It really does not matter all that much in the Z06. 2nd? 3rd? 4th? 5th? 6th? There's power available at any rpm. Obviously 8th gear at 1500 rpm isn't the fastest way to get the Z06 moving but it will still move. Which brings us to the 8-Speed automatic transmission which Chevrolet touts as shifting as faster than the Porsche PDK. Maybe it does but it is not a PDK replacement. Shift speed alone does not determine the quality of the transmission. The automatic is inferior for numerous reasons. One, who is the genius at GM who thought not allowing you to use the shift lever to change gears manually was a good idea? You might be saying, wait, there are paddles. Sure, there are. How am I supposed to hit the paddle in a low speed turn when they turn with the wheel? Especially if I want to do it as quickly as possible? I can't reach the paddle as I'm turning the wheel around and I want to keep the car in a higher gear so I don't wrap it around a tree as I go WOT out of the turn. If you leave it in D, the car will drop down a gear and kill you. Speaking of those paddles they do not work as well as advertised. They feel like a gimmick. In the 911, when you pull a paddle it is like a trigger pull. Boom, instant. You are connected to the trans with the paddles or the shift lever. Mechanical, cold, precise, and very German. The Z06 paddles feel like there is a degree of slush between you and the gear shift. That may be because there is. The Porsche PDK makes you not wish for a manual. The Z06 automatic reminds you it is an automatic. If you want the car to do what you want it to do, get the manual. You do not have to make this compromise in the 911. There were a couple instances where the automatic would not shift when I told it to and gave me an error. WTF? I tell you when to shift Z06, not the other way around. The logic of the GM automatic just is not as good and neither is the shift quality. Are the shifts quick? Hell yes! Are they smooth? Hell no! They can be jarring and you do not exactly know when they will be jarring. When WOT if you shift earlier in the powerband they are smoother but if you shift later they can be harsh. Sometimes D mode can make some shift mistakes which jar you. The Porsche PDK on the other hand is buttery smooth unless you set it on the highest mode (conveniently located right on the wheel) where it still never gets as harsh as the Z06 automatic. The PDK is better, period. Ok, what about the handling and braking? Both cars have very high limits and the Z06 amazes with how flatly it corners. It is very comfortable up until going past 8/10's. Where is 10/10's? I don't want to try to find out as the car is not mine for one and secondly 10.1 tenths will kill you. The 911 on the other hand does a better job communicating. It also feels more forgiving. It probably also makes you think you are a better driver than you are. That may be because the Porsche handles road imperfections better. The ride is great for either car but the Porsche deals with the harsh stuff far more gently. The Z06 can be jarring. On the 405 freeway over some portions I was surprised just how harsh the ride could get. The Z06 needs a smoother road to instill confidence than the Carrera. The 911's steering is heavier and more communicative. The Z06 has quicker turn in and you can steer it with one finger. That isn't bad but it is just a bit more numb. The difference from 9 out of 10 steering to 10 out of 10 steering is what warrants 911's costing what they do. The brakes are a bit of an issue as the Z06 did not feel right. The car needs to be checked for a possible warranty claim as it vibrates badly under light braking. It is puzzling as it does not always do this. When it doesn't, the brakes feel perfect. Probably better pedal feel than the Porsche. I really don't understand the shimmying and wobbling when getting on the brakes and this needs to be checked. When applying full force, the brakes work great in either car. What about the interior comfort? I was surprised I could not move the Z06 seat back further or move it lower. I'm not even tall but I wanted a few more inches of legroom. You sit higher in the Corvette. You also feel like you are in a cockpit with everything aimed at you. It is tighter and less roomy. The 911 is more comfortable without a doubt and a better choice for taller drivers. I could go on and on endlessly about these cars but I think that is enough and I'll attempt to the summarize all the aspects numerically below. Car (out of 10): Z06 | 911 Interior: Comfort: 8 | 9 Interior Quality: 9 | 9.5 Space: 7.5 | 9.5 Gear shifter placement: 10 | 9 Armrest placement: 10 | 8.5 Styling: 10 | 9.5 Drivetrain: Acceleration: 10 | 9 Torque: 10 | 9 Top end pull: 9.5 | 8 Engine sound: 10 | 8.5 Transmission: 8 | 10 Flexibility: 10 | 8.5 Handling: Steering feel: 9 | 10 Braking: 7 | 9 Pedal feel: 9.5 | 9 Ride quality: 8.5 | 9.5 Confidence: 8.5 | 9.5 Subjective: Fun to drive: 9 | 9.5 Total: Z06: 163.5 911: 164.5 Summary: Both of these cars are absolutely fantastic. The Z06 is a brute though. It is a muscle car disguised as a sports car. Despite being tighter inside it feels much larger to drive. The proportions feel big from the driver's seat. It constantly wants to pull forward. It just does not feel quite complete or refined. The best Corvette may just be a Grand Sport with a manual transmission and a heads/cam upgrade. The 911 is far more composed. You can have fun in first gear or fifth gear. The car feels more nimble, more tossable, and more forgiving. It isn't as fast but isn't that why BMS has it? Another 100 lb-ft at the wheels and I'll forget about the Z06's engine. I thought the Z06 would fill me with buyer's remorse. Instead, it reminded me just how good the 2017 911 Carrera truly is. The Z06 is the faster car but the 911 is the better sports car.

    BPC (Bimmer Performance Center) continues to expand their BMW tuning offering. You all saw their absolutely absurd 335d results. They are tackling the S55 now and their early ECU tune results are promising. This is a Competition Package car with downpipes: Pump gas, catless downpipes, and a tune. That is it. Keep in mind many of the dyno graphs you are seeing as of late are coming from pulls in hot weather. This is a 500+ whp car when it cools down. BPC is still revising the tune and E85 results are coming up next.

    Here is an easy way for F10 M5 owners to make sure they are ahead of the F90 M5 when it hits the streets. Simply get an ECU flash and some downpipes. This car features tuning by HCP through the PTF Bootmod3 system which tuners seem to be loving. A trap speed over 130 miles per hour for the 4300+ pound boat with just bolt on modifications is great to see. No methanol here, just regular fuel. If the owner wants more he can change the turbos and go big but this is a safe and reliable package that is hardly pushing the envelope but providing a big performance boost. If you have an F10 M5 and haven't flashed your car yet, what are you waiting for? An F90 M5 or W213 E63 beatdown?

    How does Renntech do this so fast? The new W213 E63 AMG is barely on the streets and already they have a Stage I M177 V8 ECU flash tune in development. This is not the final tune by any means but W213 E63 AMG S tuning is already showing huge promise. They are getting 724 horsepower out of the car which is almost another 100 horses over stock based on the baseline curve. The torque figure is 755 lb-ft: Torque gains really start to show from 3000 rpm on before leveling off toward 7000 rpm. The engine sure is revving higher and making more power up top than the M157. The downsize in displacement is hardly hurting things down low. It's a broader powerband for sure. The new E63 is a beast. Just look at the acceleration teaser in the video for yourself.

    It is always important to question this source when a 'stock' BMW M car is shown obliterating whatever it is racing. However, in this instance there is nothing difficult to believe as the Lexus RC-F is a giant pile of fail. Plus, we have already seen this race from another source. The run in the video here is a bit longer and the M4 stretches its legs by putting football fields on the RC-F. Based on comparisons going back as far as 2014 the RC-F showed it was never in the M4's performance league. Which is a shame as it would be great to see a naturally aspirated entrant in the segment offering real competition for the Germans. Only the Americans offer a real challenge there if you consider a Mustang or a Camaro to be in the same class.

    Dodson powers the quickest and fastest dual clutch Lamborghini Huracans and Audi R8's. You may remember the earlier version of their upgrade sending the Huracan into the 7's in the 1/4 mile and essentially bitch slapping Heffner and SSP (South Side Performance) back into their places. Dodson and UGR (Underground Racing) are now taking things further with the Promax Version 2 upgrade: What changes in Promax 2.0? They do not say but here is what we know about the previous version: They are up to 18 plates now and maybe more. UGR is the best bet to test this out and push further into the 7's. Dodson is quite simply the best in the business.

    Nurburgring laptimes are getting so quick they are becoming tough to even fathom. Take the new 2018 Chevrolet Camaro ZL1 ILE. Video proof was posted by Chevy showing a laptime of 7 minutes and 16 seconds. How quick is that? Well, it tops all of these cars: 7:18 - 997 GT2 RS 7:19 - C6 ZR1 7:21 - Ferrari 488 GTB It only comes up short against the 2018 Porsche 991.2 GT3 with its 7:12.17 and the AMG GT R with its independently tested 7:10.92. Considering the price of the ZL1 in comparison to the two German track specials it is most definitely a performance bargain. Just imagine what the upcoming Corvette ZR1 is going to do. A time below seven minutes sounds like a very realistic goal.

    Getting dyno numbers for stroked S85 V10's is tough to come by. Dinan never posted any Dynojet figures for their motors and that is because it would not work in their best interest to show what you actually get for the money. Troy Jeup is an alternative to Dinan and provides the most displacement for the S85 motor at 6.0 liters. So what does a 6.0 liter S85 V10 put down? 561 horsepower to the wheels on 91 octane pump gas. Not bad at all but for this engine to really shine it could use some aftermarket Schrick cams and then push for over 600 to the tires. For now, this is the most powerful naturally aspirated S85 V10 BimmerBoost has viewed a graph of.

    The other day Renntech showed that the new M177 V8 powered W213 E63 AMG S is stout and responds well to tuning. The the car is strong when tuned is not a big surprise but even stock it is doing well against some strong tuned German competition. Look at how it does in this Moscow Unlimited standing 1/2 mile event. In this first race it goes up against a tuned RS7 and beats it off the line but can not hold it off the whole way. Understandable considering how strong a tuned RS7 is. What about against a tuned CLS63 M157? It also beats it off the line but the CLS63 eventually pulls past as the traps do show it has more power. Still, for a stock car the W213 does a great job. Finally, it takes on an Evotech tuned F13 M6. The stock E63 AMG S despite having less power holds it off through the entire 1/2 mile. That is impressive. As is the stock 125.10 1/4 mile trap speed and the 153.00 1/2 mile trap speed. Yep, it's a beast.

    Who needs boost? Not this Viper. This is a naturally aspirated beast making over 700 horsepower to the tires. To put this in perspective a factory stock Gen V Dodge Viper 8.4 liter V10 produces 520 horsepower to the wheels on a Dynojet in SAE correction. Add in headers, a cam, heads, an exhaust, E85, and a Motec M1 and you get this: 742 rear wheel horsepower and 645 lb-ft of torque at the wheels. This is a built motor example although a stock internal motor should not have too much trouble matching the numbers: Imagine this paired with a 9.0 liter stroker motor:

    The Lexus RC-F and GS-F quite frankly need a supercharger. The tired naturally aspirated 5.0 liter V8 under the hood can not compete with its German competition. Even modern turbo six-cylinder motors are making far more power and torque. Just look at the baseline figure. 401 horsepower at the wheels. BMW topped this with the 5.0 liter S85 V10 over a decade ago. As did Mercedes-AMG with their M156 6.2 liter V8. Lexus is over a generation behind. Fortunately, for Lexus owner who do not want to get embarrassed (they still will lose badly to a tuned E63, M5, M3, M4, RS7, or you name it) RR-Racing has a beautiful supercharger kit. The Rotrex centrifugal blower ups output to 568 horsepower and 451 lb-ft of torque at the wheels: A massive gain. However, to put it in relatable terms this is less power than a BMW M3 4.0 liter S65 V8 outputs with a blower. A lot less power. It's better than nothing though and at least makes it so the RC-F or GS-F look like they belong in a modern performance discussion. RR-Racing's engineering work also deserves tremendous praise. We are excited to announce that after over a year in development and testing, multiple track days, desert testing, and over 10,000 miles of punishment and tuning, we are finally ready to release our RC F/GS F Supercharger kit! Our goal for this kit was to maintain stock drivability and reliability, while creating smooth, seamless, and unrelenting supercar levels of power that these great car deserves. RR670 Kit Specifications: - Power: For the base "RR670" kit, our customers can expect to make about 670hp at the crank, or 560 to 570whp (wheel horsepower on a Dynojet dyno, SAE correction -- see Dyno result chart in the product photos gallery) at approximately 6psi peak boost pressure, 93 pump gas, equipped with standard PPE headers and a high flow dual exhaust. - Tuned ECU: We have logged countless development hours perfecting our ECU tune for the RC F for ultimate reliability and drivability. No piggybacks or other BS! We have extensively developed the mapping of the stock ECU, modifying literally hundreds of maps and adding additional functionality to the fueling system that allows us to support up to 570whp without fuel system modifications. - Supercharger: Rotrex Supercharger, c38-91 (largest Rotrex SC). Rotrex SC's are extremely efficient and quiet due to their planetary drive system which spins up to 90,000 rpm, much like a turbocharger. - Dedicated Drive System: Rather than using the accessory belt to drive the SC, we designed a dedicated drive system that allows us to achieve the necessary belt tension for a reliable SC drive, without overstressing the alternator, water pump, and AC bearings. - Custom Harmonic Crank Damper: There are some overpriced Japanese SC's on the market for the ISF/RCF that eliminate the factory harmonic damper crank pulley and replace it with a simple machined aluminum pulley. We find this simply unacceptable! Working in conjunction with ATI Performance, we developed a custom tuned harmonic damper than drives the SC belt. The ATI damper has been specially developed to dampen the harmonics of the 2UR-GSE engine at high horsepower levels for the ultimate in engine reliability. - Billet Tensioner System: Most SC kits on the market use OEM belt tensioners, but we took that a step further by developing a billet belt tensioner that is both more reliable and is able to apply significantly higher belt tension than conventional off the shelf tensioners. For added reliability we use Gates Racing Kevlar drive belts and our own double bearing billet idler pulleys. - Dual "Big Bubba" billet blow off Valves: We use not one, but TWO Turbosmart "Big Bubba" 2" blow off valves. Adequate venting is essential for SC responsiveness, reliability, and drivability. - Custom Air/Air Intercooler: We use a large 4.5"x12"x10" intercooler core. These intercoolers are extremely high quality and are manufactured in the USA by Bell Intercoolers. - Genuine Carbon Fiber Intake Tubing: All visible intake tubing is made from genuine twill weave carbon fiber for an amazing look and function!

    BPC (Bimmer Performance Center) is a relatively new vendor on BimmerBoost. You may have read about their awesome M57 diesel tuning packages or their new F80/F82 S55 engine tuning recently. They put together this technical video on the N54 and N52 blocks before officially coming on board and it is well worth your time. The N54 engine block is often discussed in the forums. If you have sixteen minutes to spare watch the video below and learn a few things. If not, BimmerBoost will summarize it for you: * The N52 block includes magnesium for weight savings. N54 has steel liners. * The N54 is built more for strength than weight. * The cooling pipes are located in different areas. * The N52 does not have oil drains for turbos as it is naturally aspirated. * The N54 has a smaller bore of 84 mm. N52 is 85 mm. * The N54 has a longer stroke of 89.6 mm. The N52 88 mm. * The N54 has a smaller bore for more cylinder material. * The bottom end design is identical. * Forged crank on the N54 and cast crank on the N52. * 8-bolt main on the N54, 6-bolt on N52. * N54 cylinder head bolt is 11 mm. N52 cylinder head bolt is 10 mm. Both have 9 mm bolts in cylinders 6 and 1. * Both rods are forged. N52 has smaller 8 mm rod bolt. * N54 has larger 22 mm wrist pin to the N52 20 mm. * N52 is higher compression with N52B25 11.0.0:1 and N52B30 10.7:1. * N52 head gasket has larger cooling passages. * N52 head will physically fit an N54.

    If you are someone who just doesn't believe what you see in the video below that is understandable. It isn't even a race. What you have to know to make sense of it is that the Huracan and Aventador are very close to each other in performance stock for stock. Add a supercharger to the Huracan and it just blows the Aventador out of the water. More power, more torque, less weight, less surface area, and a quicker shifting transmission. It results in an epic beatdown. As a reminder, this is a VF-900 Huracan. BoostAddict will bring you dyno figures and specifications for it in a later article but a VF-800 Huracan recently put down 681 horsepower to the wheels on pump gas. The VF-900 utilizes the same TVS2300 blower but with more boost and different tuning. A supercharged Huracan is no joke. <blockquote class="instagram-media" data-instgrm-version="7" style=" background:#FFF; border:0; border-radius:3px; box-shadow:0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width:658px; padding:0; width:99.375%; width:-webkit-calc(100% - 2px); width:calc(100% - 2px);"><div style="padding:8px;"> <div style=" background:#F8F8F8; line-height:0; margin-top:40px; padding:28.055555555555557% 0; text-align:center; width:100%;"> <div style=" background:url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACwAAAAsCAMAAAApWqozAAAABGdBTUEAALGPC/xhBQAAAAFzUkdCAK7OHOkAAAAMUExURczMzPf399fX1+bm5mzY9AMAAADiSURBVDjLvZXbEsMgCES5/P8/t9FuRVCRmU73JWlzosgSIIZURCjo/ad+EQJJB4Hv8BFt+IDpQoCx1wjOSBFhh2XssxEIYn3ulI/6MNReE07UIWJEv8UEOWDS88LY97kqyTliJKKtuYBbruAyVh5wOHiXmpi5we58Ek028czwyuQdLKPG1Bkb4NnM+VeAnfHqn1k4+GPT6uGQcvu2h2OVuIf/gWUFyy8OWEpdyZSa3aVCqpVoVvzZZ2VTnn2wU8qzVjDDetO90GSy9mVLqtgYSy231MxrY6I2gGqjrTY0L8fxCxfCBbhWrsYYAAAAAElFTkSuQmCC); display:block; height:44px; margin:0 auto -44px; position:relative; top:-22px; width:44px;"></div></div><p style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; line-height:17px; margin-bottom:0; margin-top:8px; overflow:hidden; padding:8px 0 7px; text-align:center; text-overflow:ellipsis; white-space:nowrap;"><a href="" style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; font-style:normal; font-weight:normal; line-height:17px; text-decoration:none;" target="_blank">A post shared by Doug Almond (@almonddoug)</a> on <time style=" font-family:Arial,sans-serif; font-size:14px; line-height:17px;" datetime="2017-06-19T04:24:53+00:00">Jun 18, 2017 at 9:24pm PDT</time></p></div></blockquote> <script async defer src="//"></script>

    The 2.0 EA888 motors get the majority of the love but the IS38 turbocharger is a nice upgrade for the 1.8T EA888 engines. Keep in mind the IS38 turbocharger is factory equipment on the MKVII Volkswagen Golf R and the Audi S3. Just look at the difference going from stock to the IS38 with APR tuning. The 1.8T makes 146 all wheel horsepower and 184 lb-ft of torque at all four wheels stock. On race gas with the IS38 the numbers jump to 320 awhp and 317 awtq respectively: That is a night and day difference. The 91 octane pump gas figures for the IS38 are 313 awhp and 313 awtq so not even much of loss over race gas: This is a very nice cost effective upgrade 1.8 TSI EA88 owners. APR's software starts at $699 for new customers or $399 for existing customers. The new APR 2017 1.8 TSI Golf Sportwagen / Alltrack engine and transmission upgrades are here! 234-245 HP / 274-301 FTLBS - Stage 1 (Just software) 246-247 HP / 275-301 FTLBS - Stage 2 (Downpipe) 274-306 HP / 308-326 FTLBS - IS20 GTI Turbo Upgrade (Stock DP) 284-319 HP / 311-330 FTLBS - IS20 GTI Turbo Upgrade (APR DP) 351-357 HP / 335-341 FTLBS - IS38 Golf R Turbo Upgrade Details: ECU: TCU: IS20: IS38:

    The X7 has been in development seemingly forever. BimmerBoost spotted prototypes testing as early as 2013. With Nurburgring development taking place the SUV is poised to finally debut at this year's Frankfurt auto show in September. Why is a huge SUV testing on the Nurburgring? Well, why not? It is still supposed to be an 'Ultimate Driving Machine' although this is obviously BMW going after the Mercedes GLS-Class where they have not had any competition from BMW. Yes, these days it is easier to get a huge SUV from BMW than a sports car or Z4M. Whatever.

    LMR (Late Model Racecraft) has incredible LSX builds. They do not often provide the full specifications but they show what the cars are putting down. Like this 6th generation Camaro ZL1 making 1043 horsepower to the rear wheels at only 16 psi of boost. As for the mods this is what they share: LMR's 1200 HP Twin Turbo Package putting down 1043 RWHP on 16 PSI!! LSX 427 Twin Precision Turbos Stage 3 Fuel System Mcleod Clutch Built 427 cubic inch LSX with an upgraded fuel system and unspecified Precision Turbochargers. It's hard to argue with these results: How much money to build this? You have to call and ask. It sure is a monster though.

    BMW dominates the International Engine of the Year Awards. Rather, they used to. BMW is the all the time most awarded manufacturer with 61 awards including this years win. As of late though, BMW is getting knocked out of their traditionally dominate categories by the competition. If the only engine award BMW can win is in the 1.4 to 1.8 liter category something is wrong. The B38 is a fine motor but hardly a performance engine. It is simply a modular engine design that then lends itself to the larger B48 and B58 motors as they all share the same pistons, rods, and geometry. This is the third straight win for the B38 but let's focus on where BMW didn't win. The S55 engine got pushed out of the 2.5-3.0 liter category by Porsche's 9A2B6 last year and the engine repeats this year. The S55 at least finished second but BMW did no better than fourth in any other category. Keep in mind the B38 picked up BMW's lone engine of the year award last year as well. BMW may be pushed out of the awards entirely next year. Since the inception of the engine award competition BMW has never failed to win an award.

    The best way to improve the looks of a vehicle is a nice set of rims and a drop. This particular Mercedes-AMG C43 gets half of that recipe correct as the gunmetal VFS-10 wheels look great against the black contrast of the paint. It does sit a bit high though, doesn't it? A drop and this car would be just about perfect. The W205 design certainly works well as a convertible.

    Superchargers tend to be the most popular Coyote boosting option but it is really hard to advocate a blower over turbos at this price point. For $7k you get a system for your Mustang GT or Boss 302 that can grow with you and make power superchargers can only dream about. More efficiently to boot. Look at what you get for the money (GT30R's add a grand to the price): CNC Mandrel Bent 14 Gauge 304 Stainless Steel Headers: By Kooks CNC Mandrel Bent 304 Stainless Steel TiG Welded Downpipes: By Kooks CNC Mandrel Bent Thick Wall Aluminum Charge Piping: By Kooks X2 TiAL Sport 44mm MV-R Wastegates (With All Springs): By TiAL Sport Tial Q 50.5MM Blow-Off Valve: By TiAL Sport Aluminum High-Flow Intercooler: By Fluidyne Custom CNC Low Pressure A/C Line Stainless Steel Support Bracketry Pre-Made Turbocharger Plumbing System: By Goodridge Fluid Systems 4-Ply Silicone Coupler Kit with Stainless Steel T-Bolt Clamps: By Vibrant 2x High-Flow Air Filters: By Vibrant 2x Garrett GT3076R Turbochargers (1200 Horsepower Capable) Remote Tuning and Base Tuning Provided with Every System Look at what it can do at only 4.5 psi of boost. Yes, only 4.5 psi: That horsepower curve just takes off and keeps climbing. Note, $7k is the kit without turbos and with a pair of GT30R's it adds a grand so unless you really want to run different turbochargers the kit starts at $8k. You can go even bigger as well as they have GTX35R options. The sky is the limit with this turbo system. Build the motor and go for 1500 whp, why not?

    This is what dominance looks like. Eight straight International Engine of the Year Awards for the 2.5 liter turbocharged Audi I5? Yep. There is no end in sight either as the motor was updated for duty in the MKIII TT-RS and the upcoming Audi RS3 sedan. The all time leader in consecutive wins in its displacement category is the Volkswagen 1.4 liter twincharged TSI motor with nine straight. That engine is hardly a performance motor though. Audi has a good chance at setting a record. This engine is not going anywhere anytime soon and it is hard to imagine anyone producing a better motor in its displacement category. Only Porsche comes close with their new 9A2B4. The 400 horsepower version was not even judged this year so the odds for nine straight are looking very good.

    This is the new third generation BMW X3 for 2018. The design plays it very safe. BMW does not like messing around with its bread and butter which these days means their SUV's. The most exciting thing about the new X3 is that there will be an M or Motorsport Division version. Expect the X3M to have a revised S55 and 450+ horsepower and all wheel drive. Do not expect a dual clutch transmission. The X3 M40i of course utilizes the B58 3.0 liter I6 and an X3 xDrive30i with the B48 2.0 liter I4 seems likely. How do you like the design?

    The new GT3 is a masterpiece. What is there not to like? The 500 horsepower 4.0 liter naturally aspirated flat-6 that revs to 9000 rpm? That Porsche again is offering a manual transmission with it? That it is the closest thing on the market to a street legal race car? MotorWeek sampled the car and although they call this a test it is not a test. Maybe more of a test drive. No performance numbers are provided but we can wait for those. The feedback is that the car is spectacular. The engine noise alone is glorious. It is time for us to recognize that the naturally aspirated 911 is reaching the end of the line. Porsche does not have much more room to increase displacement and how much higher can they rev it than 9k rpm and maintain street civility? This is a very special car at a very special time in Porsche history. It will go down as one of the all time greats. Enjoy it while we still have it. This is a dying breed.

    Massive gains here for an RK Tunes custom dyno tuned F82 M4. This car is tuned on 93 octane pump gas. It also certainly sounds like it has exhaust modifications and BimmerBoost will get clarification on the full mod list. Regardless, the gains over the baseline figures of 431 wheel horsepower and 448 lb-ft of wheel torque are massive: These are Dynocom figures which in BimmerBoost's experience read a bit higher than a Dynojet. The torque figure is approaching 600 lb-ft at the wheels which is incredible. The torque curve does take a nosedive toward redline but that is the reality of BMW turbo motors. A gain of 140 lb-ft tune only is nothing to sneeze at though. <blockquote class="instagram-media" data-instgrm-version="7" style=" background:#FFF; border:0; border-radius:3px; box-shadow:0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width:658px; padding:0; width:99.375%; width:-webkit-calc(100% - 2px); width:calc(100% - 2px);"><div style="padding:8px;"> <div style=" background:#F8F8F8; line-height:0; margin-top:40px; padding:28.10185185185185% 0; text-align:center; width:100%;"> <div style=" background:url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACwAAAAsCAMAAAApWqozAAAABGdBTUEAALGPC/xhBQAAAAFzUkdCAK7OHOkAAAAMUExURczMzPf399fX1+bm5mzY9AMAAADiSURBVDjLvZXbEsMgCES5/P8/t9FuRVCRmU73JWlzosgSIIZURCjo/ad+EQJJB4Hv8BFt+IDpQoCx1wjOSBFhh2XssxEIYn3ulI/6MNReE07UIWJEv8UEOWDS88LY97kqyTliJKKtuYBbruAyVh5wOHiXmpi5we58Ek028czwyuQdLKPG1Bkb4NnM+VeAnfHqn1k4+GPT6uGQcvu2h2OVuIf/gWUFyy8OWEpdyZSa3aVCqpVoVvzZZ2VTnn2wU8qzVjDDetO90GSy9mVLqtgYSy231MxrY6I2gGqjrTY0L8fxCxfCBbhWrsYYAAAAAElFTkSuQmCC); display:block; height:44px; margin:0 auto -44px; position:relative; top:-22px; width:44px;"></div></div><p style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; line-height:17px; margin-bottom:0; margin-top:8px; overflow:hidden; padding:8px 0 7px; text-align:center; text-overflow:ellipsis; white-space:nowrap;"><a href="" style=" color:#c9c8cd; font-family:Arial,sans-serif; font-size:14px; font-style:normal; font-weight:normal; line-height:17px; text-decoration:none;" target="_blank">A post shared by Jordan H.

    A bit of confusion arose recently as AMS claimed an M133 1/4 mile record. AMS ran an 11.486 @ 117.44 in the 1/4 mile with a CLA45 AMG. Now, that may be the quickest and fastest stock M133 turbo record. The overall record is this GLA45 AMG with a Pure Turbos M133 turbocharger upgrade and methanol injection: That run makes it the quickest and fastest record M133 pass. It just edges a similar Eurocharged tuned CLA45 AMG with a Pure Turbos M133 upgrade that ran 11.526 @ 120.49. Congratulations to @Meltingtires on the record.

    The Tesla claim to fame is acceleration off the line. The P90D is all wheel drive with two electric motors and an absurd amount of torque. It is all about off the line acceleration. The Audi RS6 with the 4.0 TFSI is no slouch off the line though with a twin turbo V8 and all wheel drive. This is the Performance edition RS6 which means 597 horsepower. As this is a wagon the weight is going to be pretty close between the two. The Audi may have a 100 pound advantage. Top Gear does not list trap speeds because that would make too much sense. The Tesla edges out the RS6 which makes for a better video of course. Simply throw a tune on the RS6 and it will destroy the Model S from a stop or a roll.

    The Black Series from AMG is well known with enthusiasts. AMG would take an already high performance model and go wild with it. The Black Series has been on hiatus for a while though as Mercedes-AMG themselves could not seem to decide whether it would return or not. The head of Mercedes-AMG Tobias Moers stated there would be an AMG GT Black Series back in 2014. Some contradictory reports came out and what many thought was the Black Series version of the AMG GT ended up becoming the AMG GT R. The GT R of course is an absolute animal running the Nurburgring in 7 minutes and 10 seconds. AMG does not appear content with this astounding laptime and is preparing a Black Series version of the GT R to take things even further. What will they do? Well, probably suspension, wheel/tire, downforce, and engine revisions. Expect more power and less weight with more grip. Also expect a very high price tag although one can argue the AMG GT R is a bargain. Bring it on AMG!

    Very cool comparison here featuring three Gen V Vipers. The bolt on car you should be familiar with as a previous article showed it smashing just about everything it raced. The owner definitely can row the gears. The white Viper is an Arrow heads/cam upgraded car. That means roughly 660+ wheel horsepower. Pretty nice naturally aspirated power, right? A stock Viper makes in the ~525 whp range on a Dynojet depending on the correction factor and conditions of course. A bolt on Viper will be just under 600 wheel horsepower with the Arrow PCM. The way the first race goes down is the stock Viper trails badly as it should and the heads/cam car pulls. The second run has the bolt on Viper get the hit against the heads/cam car and the white Viper just can not make up the distance. The final run looks to be a botched start but the bolt on car pulls. Very nice real world comparison.

    It is safe to say the panel at the International Engine of the Year Awards is in love with the Ferrari F154 V8 out of the 488 GTB. Last year the motor took home four awards including Best Performance Engine, Best New Engine, Engine of the Year, and Best 3 to 4 Liter Motor. This year it takes home three awards but that is only because it can not win best new motor again. It won every category it could which is the equivalent of a motor triple crown. Best 3.0 to 4.0 liter motor? Check Best Performance Engine? Check Engine of the Year 2017? Check Back to back in all three categories? Checkmate. Ferrari took home four awards total as their 6.3 liter V12 in the F12 (replaced in the 850 Superfast with a 6.5 liter unit) won the above 4.0 liter category. Impressive considering it is naturally aspirated and since the panel did not use the new Superfast engine that likely means it will win next year. Congratulations to Ferrari on incredible performance engine design.

    2017 brings with it yet another International Engine of the Year Award for the Porsche 9A2B6 3.0 liter twin turbo flat-6. As a reminder, the motor picked up its first win last year knocking out the BMW S55 engine from the 2.5 to 3.0 liter category. Deservedly so as the 9A2 engine spools more much quickly and has a broader powerband which you can read about in a previous comparison article. It is also available in three six-cylinder flavors ranging from 370 to 450 horsepower. It also does not come with any design flaws. This was not the only Porsche engine award as their 9A2B4 2.0 liter motor won the 1.8 to 2.0 liter category. As you likely know the 9A2 architecture is modular so the 9A2 can stretch from four, to six, and even eight cylinders. That the 9A2 design picked up two wins is all the more impressive when you factor in the 2.0 liter motor knocked out the powerhouse Mercedes-AMG M133 which dominated the class.
