    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.

    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

    Damn the new 991.2 models are quick! We're talking performance not far off a 997.1 Turbo model. Don't believe it? Well, just check out the acceleration video posted below. The PDK transmission certainly helps as the car rockets through the gears hitting 285 kph (177 miles per hour) with ease. 0-60 takes just 3.4 seconds. 0-200 kph (124 mph) takes just 11.9 seconds. 250 kilometers per hour passes in 20.5 seconds. That 420 horsepower B6 turbo 3.0 liter motor (check out our technical breakdown) is no slouch. Even in stock form this is an easy 11 second car. Oh, and how about that Porsche launch control? 6200 rpm launches. Nonse of that pansy 2200 rpm stuff like the Acura NSX.

    The new NSX is going to much, much faster off the line than the previous generation car. Why? Duh, of course, the all wheel drive system. It is not just the all wheel drive but also the three electric motors that provide instant torque off the line. There is a lot of talking in the video so we'll just skip right to the actual acceleration testing. They do not time it but if you time it yourself you will see that without launch control the car hits 60 in just over 4 seconds. There seems to be a slight delay with the 'stomp on it method' before it gets going for whatever reason. No drama as it hooks up easily. The next launch is with launch control. You have to be in track mode for this. The rpm is quite low on the launch at 2200 rpm so Acura is preserving the drivetrain while using the electric motor torque to get the car moving. The engineer says 2200 rpm is optimal but that is only the position of someone who works at the company that offers a warranty for the car. The launch control launch is surprisingly benign. No fuss but clearly much quicker at around 3.26 seconds with a stopwatch. Yes, it's quick. One has to wonder how much quicker it would be with a bit more rpm from the gasoline motor though. Acura NSX Specs: ESTIMATED BASE PRICE:$155,000 ENGINE TYPE:twin-turbocharged and intercooled DOHC 24-valve V-6, aluminum block and heads, port and direct fuel injection DISPLACEMENT:213 cu in, 3493 cc Power: 500 hp @ 7500 rpm Torque: 406 lb-ft @ 2000 rpm Mid Motor: permanent-magnet synchronous AC, 50 hp, 109 lb-ft Front Motors: two permanent-magnet synchronous AC, 36 hp, 54 lb-ft (each) Total System Power:573 hp TRANSMISSIONS:F: 1-speed direct drive; M: 9-speed dual-clutch automatic with manual shifting mode DIMENSIONS: Wheelbase: 103.5 in Length: 176.0 in Width: 76.4 in Height:47.8 in Passenger volume: 55 cu ft Cargo volume: 4 cu ft Curb weight: 3800 lb

    In the Gen V Dodger Viper twin turbo world, $29,995.00 is a very competitive price for a twin turbo setup. So what is the problem? The problem is that RSI Racing Solutions has a reputation that rivals John Hennessey in horror stories which is quite the feat. What is interesting to note here is that it seems RSI was somehow able to acquire the website dedicated to their missteps as it now redirects to their main site. The Instagram account is still up though: So while this all looks very nice on paper and $29k is reasonable pricing it wouldn't matter if the price was free. RSI is a Viper black hole. Be warned:

    Evaporator comes out only one way. Dash/center console/cage/heater box completely out. I don't do short cuts. I just memorize repairs and don't waste time. Plus I hustle. I'm not like your ordinary technician. Most people don't hustle like me. Most people don't focus like me. So, based off of that, don't compare my speed and efficiency to the 98% of other techs.

    I saw pic of the way my dealer techs just did mine...I don't think there is any way around taking the whole dash out. Maybe he just got really good and memorized every screw/bolt location and all the torque specs and never wasted a second looking for a wrench etc. Definitely impressive to watch I am sure.
