    In the N54 world there are three transmissions mated to the motor as sold by BMW. There is a manual 6-speed, dual clutch transmission, and an automatic from ZF (ZF Friedrichshafen AG) which has six speeds and has the model name 6HP21. High power N54's have thus far been relegated to the manual transmission as the clutch can easily be upgraded. The dual clutch transmission is in far less N54 powered cars and although upgrades are available the amount of DCT guys pushing big power with a huge single turbo for example is relatively small at least as it pertains to N54 motors. The odd man out has been the automatic yet it is numerically the option with the most cars on the road. Why? Why has the automatic been so tough to upgrade? Well, there are a few reasons. For one, nobody has (until now) cracked the TCU or transmission control unit. Additionally, even if you have software control of the transmission there really are not any serious material upgrades that can hold big torque from say a big turbo kit. Oh, sure, people will point to Level 10 transmission upgrades but the reality is Level 10 is only an option to replace factory parts and get a broken transmission working again. They have never demonstrated an ability to hold the kind of power the manuals hold. That is where Propulsive Dynamics comes in. Their proprietary G3 material works in concert with Kolene Steels, a proprietary patent-pend bi-metallic bushing alloy and increased surface area in the holding clutches, to result in an increase in holding capacity of 30.4%. This friction increase is not some number pulled out of thin air but a result of SAE (Society of Automotive Engineers) testing. Pretty awesome stuff, right? There is much more information to come but for now rest assured automatic N54 fans that a serious upgrade that can handle whatever you throw at it is on the horizon. That means we will finally see N54's take that next step forward especially when it comes to times on the drag strip. Is 2016 the year of the N54 automatic? It sure is shaping up that way.

    So I had a slow day at work today so I decided to just draw out an idea I had for a fuel system since there hasn't been much activity on the forums recently and I'm getting bored:P. This system would be used for road-racing/auto-x and utilizes the Radium Engineering surge tank as well as a 12 gallon fuel cell from ATL and a -8AN Fuel rail. I'm not certain how much fuel flow we would need, but I'm hoping a design like this could easily support 1000-1200whp. Also keep in mind that I made up this design based 100% off of pictures and part lists from all of the current LPFP and fuel rail kits, so I'm not entirely sure if I drew this right (In which case I'll redraw it in Photoshop when I get home). So feel free to post any changes you might make (FPR location, pump type/location, etc.) or any constructive criticism, I would love to hear your opinions!

    This is becoming a big problem. You may remember that Maximum PSI was pushing their BMW F80 M3 project car pretty hard. Just earlier this month they were on the verge of a 9 second pass after going 10.2 @ 137. Then everything went to hell. So what happened? This: That was the end of the @maximumpsi 9 second chase and the F80 M3 and F82 M4 community have been holding their collective breaths since for a solution to the crank hub spinning problem. Maximum PSI has yet to comment on what they intend to do to BimmerBoost. What is the cause? It is somewhat difficult to pin down but look at this comparison of the S55 3.0 liter I6 crankshaft and the E9X M3 S65 V8 crankshaft: The S65 crankshaft is on the right and you can see timing gear and oil pump gear are a part of the design whereas the S55 does not have the same design. The S55 quite frankly is simply an evolution of the N54/N55 geometry and design which is basically the same. That makes one wonder why the N54 and N55 do not see this problem to the same degree. Is it the higher redline of the S55 that is partially to blame? Perhaps. You can say what you want about the BMW turbo era and it's easy power with bolt ons but the fact is if BMW raced the S55 design the same way they raced the S65 design no doubt this design flaw would have popped up in serious Motorsport competition and it would have been addressed before production. It is not some fluke. Here is what BimmerBoost member @sA x sKy had to say about it and his own experience: Once? Ok. Twice? Bad luck. Three times? It's a flaw. Four times? WTF BMW? TPG Tuning supposedly has a solution but @JasonTPG has yet to tell us anything about it. Their idea was to cut a notch in the stock piece but it didn't work and they are trying a different approach now: The TPG hub failed on member @sA x sKy three times: So what else can one try to prevent this? Well, Gintani thinks they have the solution: They are looking for someone to test this out. Speaking as someone who has had Gintani try various solutions with on his own car for going on six years now a word of advice is to not be anyone's guinea pig and let them try their solutions out on their own cars first. Let them assume the risk considering their track record and pay for their own development. Will the Gintani one piece crank hub solve this issue? Who knows. Maybe there just is no solution: The Gintani solution may introduce new problems. BMW seems to be aware of the issue but they still put the car in production. It's a numbers game for them. How many cars can they sell and what % will have the issue? Apparently the number is low enough to simply pay out warranty claims on those cars that spin their crank hub (and have not been tuned). You can have your bolt replaced and tightened every so often which is probably the best way to go. Maybe someone will come up with someone else. Maybe not. Where we are at right now is BMW quite simply screwed up on the S55 design and doesn't care. BimmerBoost reached out to BMW for comment on the issue but do not hold your breath for a response.

    Stucks started a thread Nizpro cracked N54 6AT tcu? in N54
    Apparently it has been officially stated that Nizpro in Australia has finally cracked the 6AT tcu and will be able to flash them. If this is in fact true, i wonder what the future holds for us 6AT guys. I also wonder if the flashing will work with those of us who already have level 10 valve bodies and converters. Interesting and fun times ahead.

    After installing my new clutch/fly and tranny mounts, it is very apparent that my engine mounts are rekt. I need to replace them asap. I have read through the few DIY's but I just wanted to see if anybody has any protips for this job. Also, is there any real noticeable benefit to choosing is "is" mounts over the regular? Ito just the right one that can be "upgraded" to "is", right?

    Hey Everyone, Itís about time for some exciting announcements from VTT. This has been a long time coming! As most of you know, I've taken over online representation for Vargas -but that's not the only thing I do for fun. The overarching announcement is that VTT is now one piece of a bigger group; Vargas Performance Group, or VPG. There are 3 major parts of VPG: 1: VTT (Vargas Turbocharger Technologies): Turbocharger Manufacture/Repair/Upgrades/Sales 2: VPP (Vargas Performance Products): Performance Parts Manufacture/Sales 3: VHP (Vargas Hi Performance): Turbocharger & Performance Parts Installation/Service Iíll quickly go over some announcements as they pertain to each category: VTT NEWS GC's: This is the one many of you have been waiting for. You know the ones -the stock location twin turbo setup that made 736 whp. Just look at the power under the curve! Street spool will be even better! The VTT GCís have started arriving and the first sets have shipped. We expect a second shipment shortly and the remainder of them by the first week in June. The plan is to quickly get caught up on all existing orders and soon after be in a position such that they are available for same day shipping. Note for those who got the ceramic coating; as of this week, itís adding around a week to the ship date. Bundles: GCís can now be bundled with installation ($1000 for inst. labor at VHP, more on that later) and/or a PTF tune ($249 for a MHD tune, $499 for a MHD tune with PI) 93 Octane Testing: I know there are some unfortunate souls out there who don't have access to E85 and for whatever reason don't want to use methanol. For them, we WILL be doing some pump gas testing. Expect this late 2nd quarter/very early 3rd quarter (read that: around July).I don't even want to speculate on dyno numbers -we'll find out while testing and post those results. VPP NEWS Vargas Performance Products. These are all teasers -think of this post as a quick look into the VPP crystal ball looking forward. Here are a few things in the works for VPP and one thing we're just too excited about not to share: Line Lock Kit: Here are a couple development pics -not final config by any means. This will fit all E9X and E8X, not sure about 535's or Z4's -we'll be looking for testers there down the road. Port Injection Plate with Top Mount Injectors: Anyone say they wanted an N54 port injection kit with top mount injectors? We heard you, and we agree -if you can fit them, top mounts are worth doing. We can and we are. ~3rd quarter 2016. S55 Love: We're not just playing with N54's here... the S55 gets some love too -how about some port injection (bottom mount -no room up top)? Oh, and GC's for the S55 are already in process -very late 2016/early 2017 release on those. Transmission Fun: By now everyone and their grandmother has heard the awesome news about Nizpro and the magic they're doing with transmissions. We're working directly with them and will have one the first fully built and flashed transmissions from them. While this (obviously) isn't a VPP product, we're very excited about this and have some high hopes for this really being a huge jump forward for the platform. VHP NEWS Wouldn't you rather have your turbos installed by the same guys who made them? A shop that understands turbos and has 100+ installs under their belts? If you're within driving distance of Hayward, CA, you can buy turbos, schedule an install, and have VHP install them for $1000 labor. Of course you still need to buy your gaskets (we have an installation kit for $230) and do an oil change while you're there, but it makes for a pretty good deal -especially after the GC's are in stock and available same-day. OTHER STUFF Expect more updates with more products, more accurate ship-by dates and more options for everyone. And I'm just getting started... Chris

    Here is the scenario. You work overseas and have a Porsche 996 Turbo. You see a classified ad go up from Vivid Racing for a 4.0 liter stroker short block advertised with a new crank, new pistons, new rings, new Darton sleeves, new gaskets, etc. Sounds good right? Especially considering the advertised $10k price is less than doing this all yourself and assembling all the parts and having the block sleeved. So what is the problem? The customer did not get what was advertised: Basically, what was advertised as new and in great condition simply was not true. Not to mention the scuffed and rusted liners with marks in the flange which he asks Vivid to replace. Vivid says Darton is responsible and Darton says they sold this to Vivid over 2 years ago and who knows what happened since then. Darton is right in this instance, they can not be expected to replace parts Vivid messed with or did not store properly. The solution here is very simple. Vivid should replace the parts, right? Well, they didn't. Rather than replacing the damaged sleeves Vivid is willing to sell more at cost since Darton won't be suckered into paying for Vivid's mistakes and should not be expected to. Vivid knew they were selling something that was not brand new and perfect as advertised and they just wanted to pass this onto a sucker who would have to shell out more out of pocket to get it working. That line about exceeding customer expectations and satisfactions is just a load of horse shit or a sick joke. This is honestly nothing new with Vivid. They will exaggerate or misrepresent things to make sales. We have seen it before such as when they claimed 407 wheel horsepower from a BMW S65 V8 with their tune on a Mustang dyno which is impossible unless one messes with the correction factor which they clearly did to exaggerate the capability of the tune they were selling. Vivid is all about making money and they do not seem to care how they get it. They basically just ship a lot of parts to a lot of people. It's why they acquired the HPF (Horsepower Freaks) name to simply utilize another brand to ship more and more parts from their warehouse. The bottom line is they don't give a crap about their customers and won't do the right thing if it means money out of their pockets. Think this is an isolated incident? Read this 60 page thread on Vivid's business practices which goes from praise to horro stories in a hurry: http://forums.nasioc.com/forums/showthread.php?t=337726 Why do people keep going to them? Caveat Emptor.

    Now this is the kind of power you like you see out of a turbocharged BMW I6. The iron block straight sixes remain king and this a reminder of that with everyone so caught up in the new direct injected BMW turbo sixes. 1178 wheel horsepower and 907 lb-ft of torque at the wheels with tuning by Jordan Horowitz of RK-Tunes. What are the specs? Here you are: RK-Tunes stock DME turbo tune package - 1600cc injectors. C85 fuel GTX 3576r turbos ICS performance Custom twin turbo kit ICS Camshafts ICS Pistons 9:1 K1 Rods M52 / S52 motor S52 crank Ported Head OEM intake manifold, OEM throttle body. Some of you will notice a dip on the 1178 pull on the graph. This is the reason: Just absolutely absurd power and this is one of the strongest street BMW's in the nation.

    Some big claims here from VF-Engineering who is known in BMW circles primarily for their supercharger kits. Those who know VF-Engineering's history know software tuning was the main weakness of their kits especially in the S54 days. Have things changed with their S55 engine tuning software for the F80 M3 and F82 M4 models? Maybe. They are making some big claims. They say they offer Stage I and Stage II flash tuning software. Additionally, they say they have TCU (transmission control unit) software for the DCT transmission: The TCU software seems to be much like the software for E9X M3's where they simply up the line pressure in the transmission to increase clamping force. This certainly is useful when torque is increased. So what are the power and torque gains? Let's take a look: Vehicle: 2016 BMW M4 (DCT) - Austin Yellow Software Level: HEX Tuning Stage ONE (username:1FastS4) Additional Mods: Completely Stock Vehicle: 2016 BMW M4 (DCT) - Yas Marina Blue Software Level: HEX Tuning Stage TWO (username:yellowssm) Additional Mods: VRSF Downpipes / Factory Rear Section / Berger "Cold-air" Intake Vehicle: 2015 BMW M3 (DCT) Software Level: HEX Tuning Stage TWO & Stage TWO+ Additional Mods: Evolution Racewerks Downpipes / Akrapovic Exhaust / Eventuri Carbon Intake / ERW Chargepipes They get up to 497 wheel horsepower and 550 lb-ft of torque at the wheels with their Stage 2 S55 flash along with downpipes, an exhaust, and intake. That is certainly the right range and they are not claiming any exaggerated numbers or posting any glory pulls. It looks like they have a few customers running their tune. The problem? It's a bench flash. That means this is basically relegated to the Southern California market and VF plans to go on a flashing tour so to speak to reach other people. Will they do that before people in other areas find a local solution though? You can of course mail in your ECU but most owners are uncomfortable with doing that. Also, who is the source here? VF-Engineering is likely buying this from someone and the question is from whom? Many tuners do this but it's good to know the source to know the quality. If we knew the source though why even bother going to VF? You see the problem. Is the option worth exploring? Sure, why not? However, once OBD-II flashing gets here the bench flashes will be a thing of the past. It's just a matter of time.

    There's so much bullshit to weed through surrounding the different flash tunes available for these cars and I know I'll get some straight answers here. Whats the scoop on the VF Engineering flash? Seems to be the latest rage but it's the first one which looks promising. As nice as the added power is, I'm no longer interested in mixing fuel every fill-up and the few "Stage 2" dynos on 91 octane so far look good. What's the underlying difference with this one versus others? Which other re-sellers are providing the same flash with a different name, and which ones are different all together? Thanks

    Well, if you want maximum naturally aspirated power this is not a bad way to go. The LS7 V8 is more than twice the size of the 3.2 liter I6 the BMW E46 M3 comes with. The S54 is arguably the best I6 BMW produced so it is a shame to see it ditched but it is also fun to see different things. The LS swap into a BMW of course is nothing new as the LS1 has been done. A guy is even doing an E90 LS1 swap with a single turbocharger on top to boot. People have done E46 M3 LS swaps and then supercharged them. For maximum naturally aspirated horsepower though the LS7 is probably the best choice as the Viper V10 isn't going to fit. The LS7 does though and this guy did some nice custom fab work especially with the headers to get everything to fit nicely. It will be nice to see the finished product in action. Source

    Hey guys, It seems that there are more and more reports on rod bearing failures so I am starting this thread to understand which factors correlate the most to failures of rod bearings in N54s. As our engines age, this may be an impending issue if we don't address it. I am hoping to collect data to find the common factors to this issue which will help us prevent it. The most obvious factor is oil dilution. Please read this if you want to know more: https://www.amsoil.com/techservicesbulletin/MotorOil/TSB%20MO%202004-07-02%20Fuel%20Dilution.pdf So for those of you who had rod bearing failures please answer the following questions: Which N54 car do you drive (Model and Transmission) Miles on the car/engine when the rod bearing failure was detected What HP/TQ were you running when you detected a rod bearing failure (Name the modifications if you don't know.) How many miles were you running the previously stated setup What tune / who tuned Did you have leaky injectors What fuel did you run Did you often turn the car off before it reached operating temperature (short trips) Did you idle the car a lot What is your OCI (Oil Change Interval) What kind of oil and viscosity do you use External factors (e.x. Shop forgot to put oil back) Much Appreciated!

    Great numbers here and he Doc Race single turbo kit for the BMW N54 motor continues to impress. This particular E92 335i is running a Comp 6267 turbocharger and boost is 23-24 psi on a 93 octane and methanol map and it goes up to 26 psi on an E30 tuned map. Here are the specs: 132k miles on the clock -93 and meth map is 23-24psi -the E30 map is 23psi ramping up to 26psi at redline. -100% Meth on both maps Mods: -Doc Race Twin Scroll manifold -JB Comp 6267 -JB4 -BMS Meth Kit -Boost Addictions Custom Calibration Very solid numbers here and obviously the methanol is a big part of it. With the meth it is possible to have an easy 600+ wheel horsepower 335i daily driver. The Doc Race kits continue to impress and reports thus far are of quality fitment and parts. Definitely a solid option in the crowded N54 market.

Here are the specs: 132k miles on the clock -93 and meth map is 23-24psi -the E30 map is 23psi ramping up to 26psi at redline. -100% Meth on both maps Mods: -Doc Race Twin Scroll manifold -JB Comp 6267 -JB4 -BMS Meth Kit -Boost Addictions Custom Calibration Very solid numbers here and obviously the methanol is a big part of it. With the meth it is possible to have an easy 600+ wheel horsepower 335i daily driver. The Doc Race kits continue to impress and reports thus far are of quality fitment and parts. Definitely a solid option in the crowded N54 market.

    These are some very quick numbers as recorded by EVO magazine. Magazine times and actual drag strip timeslips are quite different but these numbers are not shocking considering what the F80 M3 and F82 M4 are capable of in stock form on the dragstrip. The M4 GTS takes the standard M4 recipe and improves on it by stripping out a couple hundred pounds thanks to extended use of CFRP (carbon fiber reinforced plastic). The S55 engine also gets a water injection system and a power bump to 500 horsepower. Considering the standard M4 S55 motor is already making in the 500 horsepower range with dyno results showing 427 to the wheels the M4 GTS is likely at 450+ to the wheels. Despite the additional aerodynamic drag caused by the wing which increases downforce the M4 GTS accelerates very well. Under 8 seconds to 100 miles per hour was supercar territory not too long ago. Do these test numbers make the car worth $134,200? No way. Throw a tune on your M4 and be done with it if acceleration is what you are after. Actually, maybe hold off accelerating in an S55 equipped car entirely considering the engine issues.

    This actually is not something new. BMW trolled people on April Fool's Day back in 2011 with an M3 pickup truck. However, this version seems to be built a bit better. Somebody named Mad Dog Racing put this together and apparently it is quite functional and reinforced. It's a German El Camino or an M3 Camino or BMW Ranchero or come up with a name for it. What is the point? Who knows. It's one of those things that you do because you can. The S65 V8 is even supercharged on top just for good measure. That way it will get whatever it is hauling in the bed to its destination quite quickly. Source

    Hey guys, Spent a couple hours on the dyno today with our 2012 335is DCT development car. The car is 100% stock except for a dual cone intake. The car is running 91 octane fuel with no octane booster or E85 mixed in. Otherwise known as the worst gas you can tune for. All runs done in 5th gear. Temps in the 70s. First up was testing on the stock tuning for a baseline. The JB4 was installed by in "flash only" mode for logging purposes only. e.g. white subconnector left stock and JB4 on mode 4/4 so it can't influence the tuning at all. I was surprised by how choppy the timing was on the factory tuning. That's 91 octane fuel for you. I've seen the 335is factory tune go anywhere from 315whp to 335whp on 93 octane so we're at least in the ballpark here. Since the car was in "flash only" mode I decided to give the MHD v6 Stage1 ACN map a whirl. We frequently test competitive maps to ensure our customers are getting the best product available. In this case the off the shelf flash map was disappointing. We work with MHD on back end flash stuff and always look to maintain a positive relationship so I'll leave it at I think this specific map needs more work. Next up I flashed it back to stock, reinstalled the JB4 in full control mode, and grabbed a few runs on JB4 map2 and map5. I failed to capture one in JB4 only map1 although as I'm writing this I wish I had. Results were about as expected. Good power across the board with timing drops fairly similar to the stock mapping. If I had taken the time to do more runs on map5 I suspect it would have detuned itself a bit. Finally I loaded up the ina0s PUMP back end flash map and did a couple runs on JB4 map1. After these runs I spent another hour working on ina0s BEF improvements but I'm not quite ready to share info on that yet. But as a cliff notes I was able to get timing a little more stable and fix the torque limiter causing timing to go negative at 3000rpm. Still, these runs/logs on the currently available map provides a good indicator of where the JB4+BEF 91 octane DCT tuning is currently.

    Few years back I'd read about this 'water-less engine coolant' from Evan's Cooling. Anyone have first hand with it? (or something similar)

    Now this is the kind of power you like you see out of a turbocharged BMW I6. The iron block straight sixes remain king and this a reminder of that with everyone so caught up in the new direct injected BMW turbo sixes. 1178 wheel horsepower and 907 lb-ft of torque at the wheels with tuning by Jordan Horowitz of RK-Tunes. What are the specs? Here you are: RK-Tunes stock DME turbo tune package - 1600cc injectors. C85 fuel GTX 3576r turbos ICS performance Custom twin turbo kit ICS Camshafts ICS Pistons 9:1 K1 Rods M52 / S52 motor S52 crank Ported Head OEM intake manifold, OEM throttle body. Some of you will notice a dip on the 1178 pull on the graph. This is the reason: Just absolutely absurd power and this is one of the strongest street BMW's in the nation.

    BimmerBoost member @RobNyc took his stock BMW F27 X4 M40i to the ATCO dragstrip and Raceway Park (E-Town) drag strips for some runs. As a reminder, the X4 M40i has an N55B30T0 3.0 liter turbo I6 motor which is the same motor under the hood of the F82 M2 but in the X4 M40i it is rated at 355 horsepower and 343 lb-ft of torque. The X4 also of course has xDrive all wheel drive and it weighs quite a bit more coming in at 4235 pounds according to BMW. The performance is pretty good with @RobNyc consistently running low 13's. The best pass was a 13.157 @ 103.19 completely stock on 93 octane pump gas. With a tune and race gas we're talking easy mid 12's here. The ATS-V for context managed a 12.6 @ 111. Videos of his runs are below.

    In case you needed any more evidence the Pure Turbos S55 turbocharger upgrades work how about a Russian M4 running their turbo upgrade? The M4 also features tuning courtesy of a BMS JB4 with mapping from a Russian tuner. The Ferrari F12 appears to be stock. It is a potent car even in stock form with 589 horsepower to the wheels from the naturally aspirated 7.3 liter V12. It also traps just over 130 miles per hour in the 1/4 mile in stock form. The M4 runs away with this race though. Apologies for the terrible HD potato quality but it is a cell phone recording uploaded to Instagram. Hopefully a high definition version shows up later but it's easy to see that the M4 wins and additionally that it pulls 162.5 miles per hour by the end of the run compared to 155.34 miles per hour for the F12. The F12 needs some boost and people talking down on BMW's performance need to understand an M4 with mild upgrades is easily taking down one of the best GT cars Ferrari has ever made. <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:50.0% 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="https://www.instagram.com/p/BFrb-2RyLUG/" 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 video posted by Pure Turbos (@pureturbos)</a> on <time style=" font-family:Arial,sans-serif; font-size:14px; line-height:17px;" datetime="2016-05-21T18:05:04+00:00">May 21, 2016 at 11:05am PDT</time></p></div></blockquote> <script async defer src="//platform.instagram.com/en_US/embeds.js"></script>

    Great pictures, details, and results here from Fabspeed who has diligently worked on an aftermarket exhaust system for the new 991.2 Carrera and Carrera S models. Their project car is a 2017 Carrera 4S 7-speed manual with the factory Sport Exhaust system. As you can see in the above photo the factory system is not a bad design by any means but there is room to improve. Traditionally, the main area of improvement in a turbocharged Porsche 911 is in the headers and also with higher flowing cats. These are the areas Fabspeed upgrades. Let's take a look at the factory manifolds: Here is the Fabspeed design: Next up the Fabspeed 200 cell sport cats vs. the factory catalytic converters: So what is the result? Another 32 horsepower at the wheels: Very nice numbers from exhaust only changes on an all wheel drive 991.2 C4S. The peak torque figure does not change much but so what? The torque peak is early in the rev range on the new turbo motors and the Fabspeed system really starts outflowing the factory system past 4000 rpm which means much more power up top and this is really what the engine needs. Throw a tune on the engine and this car will easily be a 450+ wheel horsepower daily driver. If someone wants that tiny bit more, Fabspeed also has cat bypass pipes available. Just great work and the 991.2 is responding very well to modification. It also sounds pretty good once opened up as you can hear in the video below.

    Let's put this time in context. Porsche themselves runs the Cayman GT4 around the ring in 7 minutes and 40 seconds. That is a factory time with factory drivers and factory resources. Manthey Racing improves on that time by 11 seconds without even touching the motor. They are not doing this with more power. If they add power they can drop this time further but Manthey revises the suspension and brakes as well as changes the wheels and tires. Obviously the Pirelli Trofeo R's make an appreciable difference but Manthey Racing also adds in a roll cage. That adds weight but they make up for it with a carbon fiber hood and race seats. To put this laptime in other words a Carrera GT did a 7:28.71 time in a test by EVO and Porsche themselves got a 7:32 out of the 997 GT2 model. This is an incredible lap for the power and just a great example of superb mid-engine handling. Watch it eat up the Nurburgring corners below.
