I think Boostinwild means 525hp at the crank which is about 450-460rwhp for an 03/04 Cobra. Which would theorectically on paper have a 440rwhp BMW 335i outgunning a 450-460rwhp Cobra.
The Cobra weights 3665lbs compared to the Bimmers 3584lbs and The Bimmer has better aerodynamics .30 vs .34 for the Cobra. The Bimmer is at a weight and aerodynamic advantage.
Now comparing dyno draphs of a pullied 450rwhp Cobra and a 438rwhp 335i, you'll see that a chipped/intake/meth/ms109 335i will make 480+lbs-ft tq @1800-1900rpms as compared to a pullied Cobra making its 450lbs-ft tq @ 3700-3800rpms. Their final axle ratio is similar with the Bimmer having a 3.46 gear set and the Cobra having a 3.55 gear set.
With 480+lbs-ft tq @ 1800-1900rpms and some DRs on the 335i, I can definately see it rolling out a 450rwhp 03/04 Cobra.
Bench racing at it's best.....
I'll let you disect my Dyno sheet, and hopefully, they post a dyno sheet of the BMW.
Cobra's are known to have insane powerband and TQ Curves, etc.
Also, I can bet you, the weight is just about equal, if not heavier in the BMW looking at those big ass wheels, the aftermarket body parts, etc. Unless they took a few things out.
Either way, why don't we take what a good driver with traction and cool weather can do in a Pullied Cobra? Low 11's @ 121-123. Still waiting on the times of this BMW.
