    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.

    There is high end automotive tuning and then there is this. It makes a lot of sense for Weistec to lend their engineering expertise to the Huayra aftermarket as they have a close relationship with AMG and of course AMG builds the twin turbo V12 engine for the Pagani Huayra. The engine is not your run of the mill M275 twin V12 which Weistec has experience tuning. AMG considerably modified their V12 for Pagani use creating a 6.0 liter M158 V12. The turbochargers, software, oil sump, cylinder heads, valvetrain, and configuration are all quite different. The Huayra is rated at 720 horsepower and 740 lb-ft of torque. As you can see in photos Weistec had a Huayra on the dyno rollers and we are begging and pleading for a graph which BenzBoost will try to bring you. One can only imagine how much more power Weistec is getting out of the motor. This is one of those tuning programs where you contact Weistec and they tailor the upgrades to suit the owner. If you have to ask how much money it isn't for you. This is for a select handful of people who want more out of their Pagani Huayra. It is interesting to note a handful of owners have already contacted Weistec who provided their engineering services. Obviously you can surmise from the teaser photos that downpipe, exhaust, and software changes are where things begin but the sky is the limit. Very, very high end tuning here and exciting to see. http://pagani.weistec.com/

    This is difficult to believe but the graph is posted as proof. Powerhaus Performance obviously does some great tuning work but we have not seen much from them regarding turbo upgrades for the M157 AMG 5.5 liter twin turbo V8 platform. The dyno numbers here are from a Mustang dynamometer so keep that in mind when looking at the peak figures as they will be lower than a Dynojet and some other machines. The baseline figure Powerhaus Performance claims is from a 63 AMG M157 with a billet twin turbo upgrade. That number is 538 horsepower and 601 lb-ft of torque. Output with the Powerhaus Performance upgrade? 642 horsepower and 629 lb-ft of torque at the wheels: Now, that is a huge change. Especially when you factor in they claim this was done at the same boost pressure on 93 octane pump gas. That is the claim but there is no proof of this. It is of course in the best interest of Powerhaus Performance to show their tuning and turbos as superior to the competition as that equals sales. This raises a lot of questions though. Whose turbo upgrade is on the car? Why is the difference so large? Where are the details on their turbo upgrade? Where are the pictures? Where are the comparison photos of their turbos and the competitor's they say they are outperforming? Where is the pricing? A lot of unanswered questions here.

    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.

    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.

    This is absolutely insane naturally aspirated performance. Yes, this also is the most powerful naturally aspirated Gen V Viper in the world. A&C Performance previously hit 685 horsepower and 642 lb-ft of torque to the wheels with their heads and cam package for the 8.4 liter V10. The numbers now are 721 horsepower and 658 lb-ft of torque at the wheels: Tuned with HP Tuners on 91 octane pump fuel no less. The car does have a small compression bump to just under 11.0:1 but this is absolutely amazing pump gas naturally aspirated power. They are not done yet either. There is some more porting work and they have some higher flow heads. Check out this overlay between stock, Arrow Heads/Cam, and the A&C Heads Cam: Stock: 601/567 Arrow: 659/611 A&C: 721/658 We have a new naturally aspirated king. Phenomenal work.

    BMW is boring. Seriously, they are so businesslike in their approach to building cars now it is hard to get excited about yet another X model or yet another Gran Coupe variant. Don't even get us started on the 'i' brand. BMW at one time built some very exciting and lightweight driver's cars like the 2000 series. Of course that was back in the 60's but BMW's vehicles were a good value, lightweight, performed well, handled well, and simply were the best all around blend of daily usability and performance for the money. Road and Track regarding the 2000 sedan stated it was 'the best performing 2-liter sedan in today's market and the best handling and best riding as well.' The 2002 was a slightly shortened coupe version of the sedan platform and an evolution of the 1600-2. The 2002 Turbo was launched in 1973 and it holds a special place in the heart of BMW enthusiasts as it was the first production turbocharged BMW. Yes, that's a big deal. BMW has not built anything like it since. If you suggest a 1M or M2 as a spiritual successor you just do not get it. The 2002 Turbo is supposed to be a small, nimble, and very light four-cylinder turbo powered car. Not some parts bin money grab with an M badge tossed in. Is that what this Hommage is? No, it's a Concept so it can become whatever BMW wants it to become. If they want to produce a billion front wheel drive X1's based on a MINI platform at the very least they could produce something like the cars that got them to where we are now. At least to shut people like myself up who are wondering what the hell happened to BMW. There clearly is styling in this concept inspired by the 3.0 CSL Hommage. Many felt that car was too over the top (BimmerBoost felt it was perfect) and this Hommage Concept is far more toned down. It's still edgy though and very well designed. The rear lights take a bit too much inspiration from the i3 but the design overall is very well done. Quite modern but the 2002 Turbo inspiration is there. So why not build something cool and fun like this? Keep it light. Keep it cheap. No need to go crazy with power or try to beat everyone in performance. Win with the classic BMW recipe of offering the best all around car that is the most fun to drive for the money. What ever happened to that BMW?

    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

    The current F10 M5 is a fat pig. Do not quote any BMW Efficient Dynamics nonsense as their cars simply are fat. With the next generation F90 M5 going xDrive all wheel drive sending power to all four wheels does not come without compromises one of which is a heavier drivetrain. We know this story well just by looking at Audi's bloated Quattro cars over the years. So what will BMW do? They are striving for a 200 pound weight loss compared to the F10 M5. That would put the F90 M5 in the 41XX pound range which isn't light but certainly is better than the current car and with all wheel drive certainly a good target. BMW invested tons of money in the 'i' brand and we have yet to see a major trickle down of their weight saving technology to the standard BMW cars. The F90 M5 looks to be the first car that will employ these weight savings technologies in mass. Now, the wildcard here is the rumored rear wheel drive option. If BMW shaves mass to keep the weight down due to the addition of xDrive the rear wheel drive version of the F90 M5 would really benefit as it could be as much as 200 pounds lighter than the all wheel drive M5. A sub 4000 pound M5? It's been decades since BMW offered an M5 that light. We will have to wait and see what happens but BMW consistently makes big weight loss claims only to come up well short of their target weight. Source

    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>
