    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.

    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.

    The N54 has an open deck block as most BimmerBoost members know. It's still plenty stout but for those guys pushing limits to 1000+ horsepower eventually they will run into problems. One of the things that happens in an open deck block is the cylinders can start to lose their shape or warp. BimmerBoost member @Ericbh77 is tackling the issue before it becomes an issue for him. He explains it best: This is essentially a modified Darton design. As you can see the inserts go around the cylinders. In the Subaru world where open deck block reinforcement is common many guys insert metal pins/pegs around the cylinders and it works. This approach looks to be far more comprehensive than pegs: @Ericbh77 is also doing some other things that will be of interest and will be detailed but we can not reveal everything at this time. One thing we can say is he is looking at the cams among other things. Will we finally see that elusive 1000 whp N54? Maybe this is the year...

    You know what sells parts faster than anything else? A dynograph with huge peak numbers. People rarely look into anything beyond the superficial and if the graph says a tuner is hitting X amount of horsepower they believe it is X amount of horsepower and quickly open up their wallets. We see it all the time but what 22RPD is doing here takes tuner dishonesty to a whole new level. Some tuners inflate numbers by icing a car down, using higher octane fuel than claimed, or showing a heat soaked baseline to exaggerate gains. These guys aren't that bright. They just photoshopped in their own peak number of 670 horsepower at the wheels and then manually drew in their own horsepower curve. Somehow the thought did not cross their mind that someone can simply add in the rpm ranges on the graph as torque and horsepower cross at 5252 rpm: Horsepower is simply calculated as torque x rpm / 5252. What you see on the graph is 400 lb-ft at redline. That means 400 x 7500 / 5252 = 571.21. Not the 670 they are claiming which it looks like they just changed the 5 to a 6. Would you trust this tuner to tune your ECU when basic math escapes them and they poorly photoshop dyno graphs? What a fail. Thank you to @hobbit382 for the tip.

    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/

    BimmerBoost can relate to member @SVH who has been waiting a while on Gintani to finish his project. What is the project? A stroked S65 V8 with twin turbochargers in an E93 M3 convertible. As the convertible model is quite a bit heavier than the coupe the extra displacement totalling roughly 4.5 liters will help quite a bit. These are the specs: CSF radiator and Oil cooler, Gintani Oil pan, sleeved, 4.5 liter, stock comp, OEM main and rod bearings coated with WPC to GTS specs, ARP hardened head bolts, 5 point head work. @SVH is keeping the compression stock which will make for very good spool and driveability down low. He is not going for all out horsepower but a fun and reliable package with a ton more torque than stock. The car is still being broken in and we do not have any dyno figures yet but it will be interesting to see the torque and power curves on this motor when all is said and done. There are videos of it being started and revved below. It looks like Gintani will finally be delivering a built S65 with turbos but we have all heard that before. Hopefully @SVH gets what he paid for. The question now is, where is BimmerBoost's twin turbo built motor E92 M3?

    Is there anything more satisfying than beating a high priced Italian exotic? Especially in your BMW which no doubt is underestimated? This run is courtesy of BimmerBoost member @TZ04XJR and his Active Autowerke Level II supercharged E92 M3 DCT S65 V8. His M3 makes roughly 553 rear wheel horsepower. Keep in mind this is not the higher power Level III Active Autowerke supercharger kit. The 458 Italia is stock but potent with its 9000 rpm high revving naturally aspirated V8. It has a dual clutch transmission and the 458 is lighter than the M3 by a few hundred pounds. The passenger offsets that weight advantage somewhat but the M3 also has a passenger. It is a close run between the two with the M3 edging out up top thanks to its horsepower advantage. The 458 puts up a very good fight showing how impressive the Ferrari motor is. Maybe time for a Level III upgrade from Active Autowerke to really put some distance on the 458?

    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.

    The N54 is incredibly stout and one can make multiples of the stock power level and the engine will take it without breaking a sweat. This leads to some people thinking the motor is indestructible but it simply isn't. Everything has a limit and unfortunately BimmerBoost member @Tech found the limit of his motor. Now, how long an engine lasts or when it may let go and for what reason will vary. The amount of use, how it is used, the fuel, and even the weather all play a factor. Here is a summary of what went down: Thank you @Tech for sharing photos and what happened. 165000 miles out of the motor and pushing it with upgraded turbos at 145000 miles is certainly an indication of a stout platform. On the bright side parts are cheap for the N54 and this can be rebuilt stronger than ever. The entire motor can even be replaced for relatively cheap these days.

    Exactly like this. Ok, maybe they could have gone slightly bigger on the turbos because it's never enough boost, right? This is a custom project built for someone named Mike Murillo. No idea on the specs but who cares. We salute everyone involved.
