I raced an E46 M3 once from about a 3MPH roll. Throughout 1st gear we were even, and then due to my newly installed B&M S.S. I mishifted 2nd and 3rd (trying too shift to fast), and hence he won by a long shot. His shifts came earlier than mine.
After my race, I think they are similiarly fast as Zs. I hope to race another one soon for a better comparison.
P.S. I only have a CAI for performace mods (aside from the s.s.).
Where are you getting 325 from? Are you just adding up the "supposed" hp increases the manufactures of the aftermarket parts are claiming?
I've got an Injen CAI, Kinetix HF cats, Borla TD exhaust and I'm only putting 243 to the wheels. If I add 18-20% of 287 to 243...I only come up with 300. You might have another 15 hp at the flywheel with the plenum (I'm assuming you have either the kinetix or crawford?) and headers.
Regardless of how you're getting the numbers...I would also say that it would be VERY close. You may even lose by a tad.
Do parts tend to work off each other? For example, if an intake yields 10whp, and an exhaust yields 10whp, would the result of those togetehr be 20whp, or would it be more due to their interraction with each other??
And I definately concur about the 330i kill.. I just ate one for dinner about 10 mins ago. We went from a stop at a light, I didnt even launch. I just did a quick start and nailed it when he nailed it.. spun most of first, passed by a few carlengths by the top of second, and his HID's were in my rearview by the top of 3rd (at which point i realized I was doin 80 in a 30, **** myself, and hit the brakes :lmfao: :shiftdrive: )
Its gonna come down to the drivers. If you can drive, and you race an SMG, you will take it, regardless of what those M3 owners say about those tranny's imo they shift slow. Ive seen a stock SMG run 13.6 @ 100-good launch weak trap speed. If you race a 6-speed, it will come down to the driver with the M3 having the slight edge(past 100). Either way shift fast, have fun and post what happens...
BTW with my set-up I ran a 6-speed from a 40mph roll, I had a passenger he didnt, I beat him by about 2 1/2 cars and pulling when we shut it down at around 120.
