    A lot of talk about aftermarket N54 camshafts in the forums but little posted in the way of results. VTT tested out Schrick's high lift option and showed an efficiency gain. More tuning will take place but topping 900 lb-ft of torque at the wheels is great to see. Full details from VTT below: Hey guys. Had the car on the dyno again today, with the new cams, manifold, besides everything the same as before. 100% E85, 85% DI, a little PI mixed in, GC turbos, etc Cams are WORKING! The car made 750WHP on about 18-19 psi of boost. It took closer to 22-23 lbs to do that previously. We wanted to push a little bit so put the high map back in, and this is the first time we cannot hook up on the dyno in 4th. Dumped VHT on the tires, and roller. No dice, in 4th gear as soon as it comes on boost, redline instantly. This means we had no choice but to run 5th gear, 1st run in 5th with the higher map it hooked up, misfired at 5500, and I was astounded to see 822WHP/862WTQ. :o Fixed the misfire (plug related) and turned boost up a little, and it put down this run you see 830WHP/902WTQ by far the most TQ ever made by an N54, and honestly pretty unreal. Power was a little less than before, I think this is related to the 5th gear pull. The graph is also not near as pretty because of the slow nature of a higher gear pull. Interesting to note car makes 500WTQ at 2600, and 650 at 3K, it also holds 750WHP to redline. These motors are the real deal! On to the bad news, these turbos are tapped out, they have no business making this power, and they cannot breath up top to feed these cams. If we truly want to test the cams UP TOP, we need to put some bigger turbos on the car. Stage 3 will be back on it in the near future so we have more properly suited turbos for this kind of power. Either way, its fun to see what the N54 can do when its moving some air...:naughty: Highest run was done on 28.8 peak boost, and 20.8 at redline, poor turbos, just can't keep up. 100% WGDC by 6000RPM. MHD read slightly higher as usual, but our AEM sensor confirms actual manifold boost. Quick Break down: Closed deck short block Ported head Stock valve sizes Shrick High Lift cams Fab Factory intake manifold VTT GC Turbos VTT custom intakes VTT Silicone charge pipe ADE Catch can, with custom lines ATi super damper (No Misfires) VTT Crank Bolt Capture Spec Twin disc clutch 100% E85 VTT Double Barrel Shotgun LPS Alpha-Loc Throttle body connection More things I am sure I am forgetting MHD log is here:

    This is a messy story. It starts with a report that five BMW's were street racing in North Carolina and their cars were impounded. In this type of situation a judge could potentially decide that the owners lose their vehicles to the state. A giant penalty. That is where things get interesting. The trooper that pulled them over and impounded the cars was caught on camera going the against traffic at high speeds to catch up to them. Once he got there only those involved know what happened but it seems maybe he went overboard. Especially considering he was suspended and now resigned. You can watch the initial report below: Here is the trooper speeding against traffic: As for the charges facing the BMW owners: Brennan T. Rowe, 22, of Wayne, N.J., charged with impeding traffic & exceeding posted speed limit Anthony W. Obrien, 20, of Havre de Grace, Maryland, charged with impeding traffic & prearranged racing Hoang T. Nguyen, 44, of Allen, Texas, charged with impeding traffic & prearranged racing Tran Hai Phi, 26, of Jacksonville, Florida, charged with impeding traffic & prearranged racing Haroon Masood, 27, of Philadelphia, Pennsylvania charged with impeding traffic & prearranged racing Tamer Arslanouk, 24, of Waynesville, New Jersey, charged with impeding traffic Saad Ahmed Gil, 25, of Philadelphia, Pennsylvania, charged with impeding traffic & prearranged racing. Were these guys messing around on the road? Most likely considering the 911 calls. Did the trooper go overboard in going against traffic and potentially causing a head on collision himself? Absolutely. Was impounding the cars without evidence overboard? Yes. The bottomline? Don't be stupid and don't street race in a large group that will get attention. Source

    This is disappointing considering Nizpro's work was so promising. Just over a year ago Nizpro showed their upgrade cutting 1.5X short times on the dragstrip. Their N54 automatic transmission upgrades were supposed to be out by holiday time in 2016 but that date came and went with no release. Unfortunately, for multiple reasons, they are getting out of the platform: They do not state what the reasons are but their N54 development 335i was put up for sale. That leaves automatic N54 owners seeking big power in a bit of a pickle. Propulsive Dynamics claims to have upgrades but for owners making big torque the minimal torque capacity increase offered that still has yet to be proven on the dragstrip is likely a waste of time and money. There is always the option of swapping in another automatic transmission which is what some BimmerBoost members are doing with the AD-E 4L80 swap. As of right now the most cost effective solution capable of handling the power N54's are making in 2017 is a manual swap. A DCT swap is also possible and becoming more popular although it is more expensive than a manual swap. It does offer quicker shifts and more consistent performance though.

    Everyone gets so caught up in peak numbers on ethanol or race gas they forget N54 owners spend most of their time on pump gas. Making power that is repeatable daily on pump fuel without methanol band-aids or ethanol blends is a far more realistic goal for most. Look at what BimmerBoost member @xShadows was able to do: Mod list: JB4 + MHD - Tuned by EMP Ethanol free 93 octane Tuned on 20PSI (graph shows 21.5 but that was a boost spike) DocRace 6266 AD-E 650HP intercooler Fuel-it stage 2 550i clutch MMP Port Injection with JB4 controller A very nice result and not everyone is chasing 8XX whp on race gas.

    People love to see race videos for real world comparisons but it is also important to note that hardware can vary wildly based on the application. Tuning alone is a huge factor. What we have here is an E92 335i which is the camera car and it is equipped with Pure Turbos Stage 2 N54 turbochargers. It is tuned by someone named Pure_Evil_Tuning who tunes in Southern California. Obviously, this video is posted to show the quality of his tuning. It certainly seems the camera car is running well. The VTT GC equipped car gets pulled which with E85 and Port Fuel Injection in theory should not happen. Both are stated to be at 25 psi but who really knows if that is true. A rematch with more details would be great to see. EDIT: Somebody tried to pass the VTT car off as a GC upgraded car. It is running the Vargas Stage 2 N54 upgrade at 19 psi. Additionally, the car has some compression issues.

    Dodson is the premier name in DCT (dual clutch transmission) upgrades. They were the only company that was able to deliver a working DCT transmission upgrade for the E92 M3 and their BMW products are simply the best in the business. The F10 M5 and F13 M6 DCT transmission will start slipping once you start pushing the S63TU motor. Where the limit is can be debated based on how the car is tuned and utilized. Running it from a stop obviously is more harsh on the driveline than rolling into the throttle. This is a transmission from an HCP tuned F10 M5 through the PTF Bootmod3 system with a Pure Turbos Stage 2 S63TU turbo upgrade. The torque increase had the owner seeking out a transmission solution and he went with the Dodson Sportsman's Plus 10 plate upgrade. Here is what is included: Yes, this upgrade will work for other DCT BMW's as well. They all share the same basic Getrag box. So far 10 M5 and F13 M6 DCT boxes with Dodson upgrades are taking whatever owners throw at them and with how much torque these engines generate, that is impressive.

    Dinan is no stranger to hypocrisy. Remember when Dinan stated piggyback tuning was bad? Well, now it's suddenly good when Dinan is selling Dinantronics piggybacks. Speaking of which, Dinan specifically had a tester release a dyno graph of their W205 C63 AMG M177 tune. That is odd for a company that took the position for decades that dynos are not useful as they claim they are easily manipulated and often lie. Dinan recently regurgitated on social media an ancient article from Car and Driver where Steve Dinan essentially misleads people into thinking dynamometers are not reliable and can not be trusted. The article is a steaming load of crap. Why? Because if you want to manipulate a dyno you certainly can. You can move fans around. You can play with correction factors. You can change sampling rates. You can go out of your way to make the data useless. You can also use it properly and have reliable data. Why is it that Dinan went from never releasing chassis dyno graphs to now embracing them? Because in the turbo era they will not be able to sell products without them. Even in the turbo era they have fought being forced to release graphs. Why? Because they are not flattering. For $2500 this is what a Stage I Dinantronics gets you on an F80 M3 and F82 M4 S55 motor: That is a lot of money to pay for 20 whp. Especially considering a company like BMS offers much more power and torque for far less money. Additionally, BMS somehow knows how to use a dyno and releases their products with graphs. As do flash tuners. Dinan did not post that Dynojet graph of their box. Someone who bought their product went and got some dyno pulls. They probably cried afterwards. Who is going to buy the product after seeing that? Dinan is attempting to adapt their Dinantronics piggyback to as many makes as possible. They are trying to enter the VW and Audi market but without dyno graphs they will not be taken seriously. APR provides dyno graphs. APR has independent results that verify their gains. Is Dinan saying APR knows how to use a dyno but they do not? A company like Dinan could get away with not posting graphs in the naturally aspirated M era. People tried to eek out horsepower and would pay thousands for ported throttle bodies that maybe gave a few horses up in the rev range. Yes, seriously. Not enough power was gained to offset variances from run to run. A dyno would not help sales. It would do the opposite. Look at this: Seriously? This is the brilliant Steve Dinan? He provided proper airflow and the car produced what it was supposed to produce. He can not make it say whatever horsepower he wants to he can only slant output downward. What he is doing is purposely restricting airflow to skew the numbers. Notice how he can't deliver 800 horsepower on the dyno by playing with fans for example? He can only go from what it is making to less. This is not evidence of a dyno not being reliable but operator error. What is truly humorous is Dinan is now marketing their C63 M177 tune with a Dynapack graph. What happened to it not being reliable? Why does Dinan even have a Dynapack in the first place? Let's for a moment even indulge Dinan with this misleading dyno nonsense. Why do not they not provide 1/4 mile times then? Why do they not do GPS timed runs? Because none of this will help them get sales. Literally everyone else in the industry has a stronger product from a performance perspective. We are not saying Dinan's product is bad. We are saying a dyno is a tool that when used properly is very useful for serious tuners. Those tuners know how to operate their dyno to get results. Funny how in the real world Dinan's products perform exactly as you would expect based on independent dyno tests.

    The BMW M3 and M4 S55 motor is doing impressive things on the factory fuel system. The direct injection system is upgraded compared to N54 and N55 era BMW I6's. Getting bigger injectors for direct injection never seemed to be a problem on those older motors but getting pumps to drive fuel through them sure was (and is). AWRON in Germany says they have upgraded high flow injectors for the S55 direct injection system. That is about all they say though. No details such as flow, pricing, or what kind of power levels these will support are provided. Maybe the S55 motor will not have to lean as heavily on methanol and port injection in high power setups.

    Many European BimmerBoost members feel slighted as they do not have as many turbocharger options as US members. Well, in comes Lynx to the rescue as they are a European based N54 turbo option operating out of Switzerland. The Lynx turbochargers are available in two options: RS-650 and RS-750. As implied in the name, the 650 supports up to 650 horsepower and 750 up to 750 horsepower. Simple, right? Let's look at the design. The turbochargers feature cast manifolds and housings. The manifold diameter is larger than the hybrid options on the market as is the A/R of the turbine housing. High performance ball bearings are utilized. So what are the compressor wheels? RS-650 utilizes the TD04L-16T and the RT-750 the TD04HL-19T. The air intake is 2.0 inches in diameter compared to 1.75 inche for stock. You will need to upgrade pipes to accommodate the larger diameter. The turbine features 9 blades. Lynx states this makes it lighter than 11 blade setups as well as offering higher theoretical flow. Ok, so what is the pricing? Here you go: To order, go here: Further questions can be answered by @Donvittorio on the forum. BimmerBoost looks forward to seeing results from members trying out this option.

    This is a bargain in the Porsche world. Based on the price in Euros we expected a US Dollar price point of just over $10k. At $7495 from Suncoast Porsche the X51 Power Kit is a huge bargain considering it is also backed by the Porsche warranty. The X51 Powerkit bumps a Carrera S up to GTS spec. That means larger turbochargers and a stated output of 450 horsepower which is a bit conservative based on early dynographs. The real trick here is for someone to figure out how to get the X51 kit working on base 991.2's. That will require aftermarket software to sort as a Porsche dealer will be prevented from doing it either with software roadblocks or simply by company policy. Only for Carrera S/4S models with Sport Chrono Package (QR5). If you don't have Sport Exhaust, you MUST add it. Genuine Porsche engine upgrade kit. Performance increase to 450 hp (331 kW). Includes two larger turbochargers, modified brake cooling (if vehicle is not equipped), optimized engine management, new engine compartment styling trim cover with Carbon inserts, and optional Sport Exhaust System (if not equipped).

    This is a pretty big development in the flexibility of the Bootmod3 software. If you are a PTF (Pro Tuning Freaks) customer you will soon have access to an editor which will allow you to tune on your own or have a tuner offer you a custom professional tune. The details below are from PTF but essentially if you are a licensed BM3 user you can register yourself as a tuner and tweak to your heart's content. Those who are not registered users can purchase a tuner license. As we're getting very close to the open beta release thought we'd throw together a screenshot of the map editor that will soon make it to a wider audience. What you see below is an editor that will come up for any bm3 user when/if they wish to take things into their own hands, or, work with a tuner of their choice. For those comfortable enough to have fun in the editor you'll have access to close to 300 tables to adjust all of the tune aspects we also tune with for our OTS maps. Every table we touch will be part of the editor. Any new advances made will also be exposed to the editor on an ongoing basis.On the tuner front, we've built a feature into it to allow the end user to send their stock or tuned map to a registered tuner of their choice. Any current licensed bm3 user can register themselves to be a tuner. Those without an existing BM3 license will also be able to purchase a tuner specific license which doesn't require a DME unlock of their own car to offer assistance in tuning any given bm3 user seeking out their help. More to follow on that very soon. We can't wait to cut a first open beta release for everyone looking to use it. We're hoping for lots of feedback and everyone is welcome :drink:With ultimate power comes ultimate responsibility...and good times :)

    Let the speculation and virtual reveals finally be put to rest. This is the 2018 991.2 generation Porsche 911 GT2 RS. It is the highest performance 911 ever built by Porsche for street use. With 700 horsepower, 553 lb-ft of torque, PDK, and a curb weight of 3241 pounds this car is going to be an incredible performer out of the box. Many speculated the GT2 RS would have 650 horsepower. PorscheBoost thought otherwise: They need this level of power to go toe to toe with the big boys. Furthermore, Porsche has a Weissach package which shaves another 40 pounds: Magnesium wheels? Nice! The package isn't cheap but this isn't a cheap car and materials like magnesium are expensive. As for handling, the suspension is obviously tweaked by the GT2 RS wears 265/30/20 tires up front and 325/30/21 tires in back. Awesome? Awesome. Atlanta, Georgia. The fastest and most powerful street-legal 911 model ever is ready for launch: The new 2018 Porsche 911 GT2 RS is celebrating its official world premiere at the Goodwood Festival of Speed in the UK from June 30th to July 2nd. At the heart of this high-performance sports car is a 700-horsepower twin-turbo flat-six engine. Weighing in at 3,241 pounds with a full tank of fuel, the lightweight two-seater accelerates from zero to 60 miles per hour in 2.7 seconds. The new 911 GT2 RS can reach a top track speed of 211 miles per hour, and it surpasses the 2011 911 GT2 RS by 80 horsepower. The 2018 911 GT2 RS delivers 553 lb.-ft. of torque, an increase of 37 lb.-ft. compared to the previous 911 GT2 RS. The 3.8-liter engine in the GT2 RS is based on the power plant found in the current 911 Turbo S model. In order to increase performance further, larger turbochargers push an increased volume of air into the combustion chambers. A new additional cooling system delivers optimum cooling at peak loads by spraying water on the intercoolers when the intake air temperature reaches a determined threshold. This reduces the inlet temperature under boost and allows for optimum power output, even under extreme conditions. The customized GT seven-speed double-clutch Porsche Doppelkupplung (PDK) transmission in the new GT2 RS enables maximum efficiency with uninterrupted torque transfer. The specially developed lightweight titanium exhaust system weighs around 15 pounds less than the system used in the 911 Turbo and delivers a particularly emotional sound. Porsche Design is celebrating the debut of this very special high-performance sports car by releasing a special-issue watch. Offering a nod to the world of motorsport, the Porsche Design 911 GT2 RS watch is exclusively available to owners of the new vehicle and can only be ordered in conjunction with the new GT model. Race-bred chassis for exceptional cornering The 2018 911 GT2 RS has exceptional dry grip thanks to its race-bred chassis with rear axle steering and Ultra High Performance (UHP) tires. The stability management system is tuned for spirited driving in the new 911 GT2 RS. The PSM can be deactivated in two stages using the ESC OFF and ESC+TC OFF functions. Large air intakes and outlets and the striking rear wing underscore the emphasis on aerodynamics and down-force. The large, wide wheels with 265/35 ZR 20 tires at the front and 325/30 ZR 21 tires at the rear help ensure outstanding braking and cornering potential. The 911 GT2 RS features Porsche Ceramic Composite Brakes (PCCB) as standard. The front fenders, wheel housing vents, outer shells on the Sport Design exterior mirrors, air intakes on the rear quarter panels, and parts of the rear are made from carbon fiber reinforced plastic (CFRP), as are many of the interior components. The front luggage compartment lid is also made from carbon fiber to make the vehicle as light as possible, while the standard roof panel is made from magnesium. Both of these body panels feature a visible recess in the center, a design element previously used on the 2016 911 GT3 RS. A truly sporty interior The interior of the 911 GT2 RS is dominated by red Alcantara®, black leather, and carbon fiber trim pieces as standard. The GT2 RS Sport steering wheel with shift paddles is also included as standard. Drivers and passengers can experience the driving dynamics of the high-performance sports car in Full Bucket Seats with carbon fiber reinforced backrests, which offer a high level of comfort and lateral support. As in every 911 model, Porsche Communication Management (PCM) serves as the central control unit for audio, navigation, and communication. Porsche Connect Plus and the Porsche Track Precision app are also included as standard, enabling detailed recording, display, and analysis of driving data on a smartphone. he optional Chrono Package expands the PCM functions to include a performance display, which can be used to display, save, and evaluate lap times. The package also includes a stopwatch on the dashboard featuring an analog and digital display. The Chrono Package on the 911 GT2 RS also provides preparation for the lap trigger available from Porsche Tequipment. When using the Porsche Track Precision app in conjunction with the infrared transmitter placed at the side of the track, the lap trigger receiver enables drivers to record lap times with a higher level of precision. Exclusive watch for owners: Porsche Design 911 GT2 RS Chronograph Porsche Design has teamed up with Porsche Motorsport to develop the 911 GT2 RS Chronograph exclusively for 911 GT2 RS owners. The timepiece housing is made of lightweight titanium. At its heart is the first clock movement developed by Porsche Design, the product of three years' work. The caliber 01.200 includes a flyback function, a load-path-optimized movement bridge, and an official COSC certificate of authenticity. The flyback function is inspired by motorsport and represents a special feature of the Porsche Design GT2 RS watch. On a traditional chronograph, the buttons must be pressed three times in order to measure consecutive time intervals: The first press stops the chronograph, the second resets it, and the third restarts the measuring process. On chronographs with a flyback function, these processes happen automatically and in rapid succession. The stop function and the ongoing time display are clearly separated using yellow markings. Many of the details on the timepiece are based on the design details of the GT2 RS. The tungsten winding rotor is modeled after the rims of the 911 GT2 RS. The clock face is made of carbon fiber, while the design of the time display matches the instrument cluster and the tachometer. The 911 GT2 RS and its watch counterpart are exclusively available at authorized Porsche dealers worldwide. The vehicle and watch are produced and customized in line with each customer's wishes and are delivered together. Pricing and availability The 2018 Porsche 911 GT2 RS model is available to order with a base MSRP of $293,200, excluding the $1,050 delivery, processing and handling fee. It will reach U.S. dealers in early 2018.

    This is an N54 with a single turbo conversion from Pure Turbos. The turbocharger is a Precision 6266. Certainly not a small turbo and there is no denying it looks great under the hood. As for power when tuned on race gas by Precision Tuning it made 680 horsepower to the rear tires. This is uncorrected which means that is the horsepower it made in the conditions it was dyno'd. A graph with rpm and torque showing would be much preferred but beggars can't be choosers. This is a stout N54 however you look at it.

    Maybe 2017 will be the year of the N54 camshafts. Schrick officially released their option earlier in the year and the first US batch was claimed by enthusiasts. The thing is there is yet to be a single person showing positive results with the Schrick cams although several people are making such claims. Schrick obviously is a large supplier of camshafts with close OEM ties but Cat Cams in Belgium also has a history of delivering hot BMW cams. Cat Cams provides the specifications on their three flavors of N54 camshafts but pricing information is not provided. A dealer would likely have this info. Additionally, BimmerBoost does not know of any N54 members trying out or running the Cat Cams offering but this will likely change as tuning options for cams flesh out.

    The BMW F82 M4 GTS is supposed to be the highest performance BMW in the lineup and ready for track duty out of the box. For the asking price of $134,200 you expect to have great equipment. The Ford Shelby GT350R Mustang is half the price yet it comes from the factory with lightweight carbon fiber wheels. What exactly are people paying for on the M4 GTS? HRE shaves 32 pounds just by switching to their R101 wheels. This is with a wider rear wheel: BMW was supposed to shave close to 300 pounds yet missed their claimed M4 GTS weight targets completely. It's no wonder the M4 GTS is getting beaten by everything.

    A bolt on F80 M3 or F82 M4 is a potent thing. This F80 M3 has a BMS JB4 tune on Map 2 and is running an E85 blend. Additionally, the car has catless downpipes and an intake. The Hellcat is an 8-speed automatic that is completely stock. The F80 M3 handles it well and pulls decisively. Impressive for sure. Now, before the M3 got downpipes and other bolt ons it ran a Ferrari 458 Italia with just the JB4 and an intake on pump gas. It does not take much to make an F80 M3 stout:

    A Hellcat is no joke and a tough task for any N55 even in stock form. This E82 135i has a DCT transmission and the Pure Turbos Stage 2 N55 upgrade. It also has BMW JB4 tuning as well as Fuel-It! supplemental port fuel injection. It is amazing how easily the car handles the Hellcat from a roll. Honestly, this isn't even a close race. It would be interesting to see what this 135i is trapping in the 1/4 mile.

    The S55 motor is a hair from the 9's on the stock internals. Yes, we have at length talked about motor issues but it certainly is time to give big credit to the powerplant. Making impressive power and torque with the S55 motor clearly isn't a problem. What is the recipe for this result? Here you are: - Pureturbos Stage 2 - Precision Tuning Motorsports BEF - Burger Motorsports JB4 - FBO - DDS clutch pack - FULL WEIGHT - Race Fuel - Stock motor - Stock Fuel systems At this level you will need a transmission upgrade and new BoostAddict premier vendor Dodson is able to supply the clutch packs that will hold on a stout launch: The car is also on the stock fuel system. This is the same car that previously set the stock internal S55 record at 10.25 @ 136 miles per hour. It made 652 rear wheel horsepower at that time. Congratulations to all involved!

    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.

    These are the two highest performance editions of their respective models. That said, the Chevrolet Camaro ZL1 and the Ford Shelby Mustang GT350R go about their business very differently. It is no secret this website loves the 5.2 liter naturally aspirated Voodoo V8 under the hood of the Mustang. It does not have the raw power and torque of the LT4 but after some hands on experience with the Chevrolet LT4 supercharged 6.2 liter V8 engine that is not necessarily a bad thing. Let's get on to the comparison. MotorTrend got a manual ZL1 for this comparison as they should. The 10-speed auto is quicker shifting but ideally you want to keep it apples to apples. Well, ideally you would have a ZL1 with the automatic and one with the manual. Additionally, MotorTrend did not get a 1LE optioned ZL1. What jumps out instantly? The ZL1 is 200 pounds heavier at 3912 pounds. Heavy. The weight distribution is 54/46 front to back for both cars. How does a drag race between the two go? Predictably. The ZL1 demolishes the GT350R over a half mile. If you are just interested in raw power the choice is fairly easy. Well, unless you intend to add your own blower on the GT350. The two presenters babble on and on endlessly and basically come to the conclusion that the GT350R has the better sounding motor and that the two cars offer great value. The Camaro also feels a bit smoother. What happens on the track? This: The ZL1 edges by 4/10's of a second. Considering the power disparity, that is not much. The GT350R sure seems to be doing more with less. How do these times stack up context? Overall these are two phenomenal cars. The GT350R offers more of a race car feel and an amazing V8 that is a dying breed. The ZL1 is more about muscle. That is fine. The world is a better place with both of these cars although the GT350R sure feels a bit more special. MotorTrend chooses the GT350R as the better car. They get it right.

    BimmerBoost wrote plenty on the topic of S55 crank hub spinning issues. Various solutions have been tried with varying degrees of success. The issue is complex without a real solution in sight but VTT may be able to help mitigate the issue. This crank hub capture idea is something VTT also applies to the N54 motor with some design differences. They explain it best below: Worried about your S55 crank hub spinning? All the reports of spun hubs making you nervous about turning up the power? Want a little extra security your S55 crank bolt wont back out leaving you with 24 bent valves? Here is an easy, and cost effective way to do that. The VTT S55 crank bolt capture. slips over the head of the crank bolt, fully encapsulates it, and locks it to the crank hub, meaning it cannot back out no matter what. The VTT-CBC is 100% Billet Aircraft Grade Aluminum, Anodized black to protect it from the elements, and give it a stealth look. While this is not a full fix for all crank hub spinning issues, we have found most of our issues have stemmed from the bolt itself backing out, and this is a great way to keep that from happening. Extremely light weight at only 1.3 Oz's it adds virtually no weight to the crank which is important for balance, and vibration. Price is $99 for hub capture, and all 12.9 hardware needed for install As always email any questions to

    Awron is doing some very interesting things in the BMW aftermarket. Recently they posted about their S55 motor fuel injector upgrade and then they followed it up with this turbo upgrade announcement. It seems they intend to pair the upgraded injectors with their turbo upgrade package along with water injection: We want to see pricing information and dynographs but the more turbo upgrade options, the better.

    An acceleration comparison between these three cars is something we have already seen but the more data the better, right? A few months back Carwow tested this same trio and the Alfa Romeo was the winner with the Mercedes-AMG C63 S bringing up the rear. Somehow the W205 Mercedes-AMG C63 S goes from last to first. Odd, yet not surprising as the M177 4.0 liter twin turbo V8 is a beast of a powerplant. How do you explain this variance though? These days you have to be wary of a manufacturer providing a ringer. Whatever the reasoning in this test the C63 AMG S is easily the strongest car of the three. It shows its power advantage past 100 mile per hour where it catches up and passes the Alfa en route to 150 miles per hour. That is strong evidence of much more power especially in the heavier W205. Traction plays a huge role and once that is mitigated the C63 is able to stretch its powerful legs.

    For regular readers here seeing a tuned Audi RS7 4.0 TFSI V8 running low 10's at the dragstrip is no surprise. APR tuned Audi RS7's run low 10's at over 130 miles per hour like clockwork. It is amusing watching this pair of big 4500+ pound German tanks easily dispatching Mustangs and Corvettes. The question now is, when does the RS7 break into the 9's?

    Very nice pump gas results here and some serious power of the W205 Mercedes-AMG C63 and its M177 4.0 liter twin turbo V8 motor. This 2016 Mercedes C63 S is putting out 623 horsepower and 659 lb-ft of torque at the wheels. No methanol, no race gas, just a simple mod list: PureTurbos Stage 1 M177 upgrade Eurocharged: Downpipes Eurocharged: Ecu tuning Pump gas 94 Octane

    If this does not convince you to run methanol in your BMW what will? The only way to have big pump gas numbers without any E85 locally available at the pump is to utilize supplemental methanol injection. Either do that or dial the power down. With 632 wheel horsepower and 620 lb-ft at the wheels (please post the full graph and correction factor people) why would you want to dial it down? Methanol makes this possible on pump gas: As for the full mod list: - PureStage 2 hi-flow - Jb4 - FBO - Meth Kit - Stock dct clutch packs - 93oct/meth - Stock BEF Very nice numbers for those mods and numbers that can be repeated daily.

    Well... this happened. It is understandable to love cars and certainly understandable that a shared interest in cars can bring two people together. This couple maybe took it a bit too far by sharing a wedding kiss as tire smoke filled the air. How exactly is rubber going up in smoke and filling your lungs sexy? Whatever, any woman willing to do this is a keeper.

    Plenty of discussion on BMW N54 intake manifolds but few independent testing results. Fab Factory's billet manifold is a work of art by itself but the question is can it provide a performance benefit? BimmerBoost member @martymil put it to the test in his BMW E82 1M. His results are below but also keep in mind he has upgraded N54 turbochargers. They are RB Classics: Thank you to @martymil for providing us our first back to back results, stock vs our N54 Port Injection Billet Intake Manifold on a 1M! First dyno is a direct swap of intake manifolds, absolutely NO changes except for intake manifolds: And with a few flash tweaks/minor retune: Logs attached in the OP

    Why would you do this to a Ferrari 360? Maybe it has something to do with the clientele who can now afford these models. Buying a Ferrari just to chop it up and ruin the aerodynamics plus the suspension is idiotic. Yet, here we are. Another car destroyed by LB Performance. Maybe they just hate functional cars? Somebody please stop Liberty Walk before they ruin more cars. These kits and this stance garbage is spreading like herpes.
