Had a chance to put our buddys new M3 on the dyno to see what his chip would do (not sure what chip it is/ not familiar with German aftermarket)
everything else is stock

I thought those were rated at 400 BHP from the factor. Assuming a 17% driveline loss that should be 332WHP from the factory, give or take according to dyno and atmospheric conditions, etc.

414hp actually. It seems like a lot of drivetrain loss, but it is going through a 7-speed paddle shift transmission and that could account for the extra loss.

That'd be more like 20% off stock. Possible I guess, but that's like AWD cars now.

yah this is the isf we did which I think is rated at 416 flywheel, seems to have less drive train loss

jesus... those are really really bad numbers IMO

for a 70K V8 M3.... wonder how much worse it is stock?

I know (for comparison purposes) I could pick up 13whp/15wtq with a basic chip alone


Stock Numbers(Motor Trend)
414 HP SAE @ 8,300 rpm; 295 ft lb @ 3,900 rpm
3700 Curb Weight

I agree, the hp does seem low. The tq is actually high though

So Mr. AMG, ZO6 v. M3. What say you?

[SoCalC55]

Z06 > New M3 > Me (on paper the M3 has me by half a second to 60. I havent been able to mess with one in the real world however; yet )

Although if I were to be more correct...

Z06 > C63 > M3


mmm Z06

Any dyno #s for a Vishnu tuned 335? They claim 420hp???
If so thats probably more cost effective than an M3! No gas guzzler tax either :P
