The Shelby GT500 is a completely different animal compared to the M3. I just sold my GT500 and put in a order for an Alpine white 2010 BMW M3 Coupe.
I had a tremendous amount of upgrades for my GT500. I actually put down 712RWHP and 622 RWTQ with a Kenne Bell SC. There was no car that could catch me once going. I smoked Porsches, Vettes, BMW's, Audi's just to name a few. Top speed by a friend of mine after governor removed was 205 mph on the Autobahn. Traction was obviously an issue. :-) The reason I switched was that after awhile the noise, vibrations, horrible weight distribution, crappy suspension setup etc, I had enough. It did not feel like the car worked as a unit but instead as a combination of different performance parts. There was no harmony there. I actually learned that I enjoyed road racing far more than drag racing. After attending the 2009 Nurburgring 24h I knew why. The only thing I don't like about the M3 is the minimal performance gains you get with aftermarket upgrades. A tiny increase of 10hp here or 15 tq there will not make any difference compared to the other beasts out there. |

That must be the understatement of the year. (I think you will be happy to know), M3 can gain anywhere between 40 - 60 wheel HP with bolt ons and tunes up to 400 wheel HP (480 ish crank HP). The exhaust alone gives 20 - 25 wheel HP from what I have seen. Then there are the stroker and supercharger option, which might be pricey, but still make it very fast.
Not close to your GT500, but still a far cry from 10 - 15 wheel HP.

Just look at the Dinan website. High Flow Intake for $850 = 8hp and 5tq http://www.dinancars.com/store/produ...cat=818&page=1 High Flow Throttle Bodies for $2300 = 7hp and 5tq http://www.dinancars.com/store/produ...cat=818&page=1 Free Flow Exhaust for $2300 = 6hp and 5tq http://www.dinancars.com/store/produ...cat=818&page=1 The only thing they offer that will increase your HP and TQ significantly will be a whole new engine for about $23,000 which makes no sense at all. I have not seen anything else yet so please let me know as I'm very new to the BMW scene. I know this is a very new M3 so it usually takes some time for the aftermarket scene to catch up. Thanks... |

I would not put too much stock in just one source especially if it is Dinan. There are much better companies out there. Being a tuner, I am sure you know looking at real world examples is the best way.
For example, this fellow on this board gained 50 wheel HP from the mods he has listed before even the full tune (70 wheel HP with full tune, which makes it around 500 HP crank HP), which are only 4 or so (his baseline is very low compared to stock M3s, but he dyno'ed on a Mustang dyno, which is famous for reading very low and all his dynos were at the same place within a day of each other so all that matters is that it is an apples to apples comparison). You might want to read through the entire thread and might find it informative. http://www.m3post.com/forums/showthread.php?t=322545 Quote:

Both of these cars are very different, one being a muscle car, the other being a more luxurious GT car. Take your pick. I have a friend who's got a GT500. He's more of a straight line power guy, but Id take the M3 due to the crisper handling. |

Yes, the gap is not that much. From what I understand, the stroker is far from maxed out at 520 HP. There is much more power to be had. It can easily put out a lot more power due to the increased displacement.
Another thing is that the stroker lengthens the stroke, which means less top-end focused car giving it a much thicker area in the midrange and low-end. You can see it in the torque figures, which are 427 ft-lbs of torque compared to a gain ~ 35 ft-lbs with bolt-ons and tune (which makes it around 330 - 335 ft-lbs crank and 500 HP) while both are much closer in HP numbers. As you can see below, pencilgeek with his stroker M3 dyno'ed after tune around 446 wheel HP, which is a good 46 wheel HP more than a fully tuned bolt-on M3 (~ 400 wheel HP). http://www.m3post.com/forums/showpos...6&postcount=55 Quote:

I know the stroker lengthens the stroke making it a lower revving motor, giving way to the lower and mid range power, but I personally wouldnt want to kill the power at high revs. |

From what I read from these guys, the peak power gets moved down to 7500 - 7600 rpm and the torque curve is still very healthy up to 8000 rpm. From 8000 - 8400 rpm is where the stroker M3 torque curve might suffer the most due to the lower compression and lengthened stroke.
I think most full bolt-on and tune M3s trap around 117 - 118 mph. Not too sure about the stroker M3 since no tests have been done yet. Quote:

not many but here are some i know of ESS, Gintani, G power.
ESS is the only one i know of with long term miles on it. Gpower had problems with there early ones and alot of them blew up. i believe they have it all sorted out now. Gintani just recently came out with theres i believe. there is info on all 3 here if you search for some of the threads they will come up or contant the vendors here also Stroker in my opinion is the more reliable route if you plan to keep the car long term but not as much power as a SC. there is potential for further power with the stroker though but obviously more money good luck
