actually i think they are pretty equal on weight. the 430 weighs about 1500kg ans i doubt the cobra is much less than that.

It looks like the F430 weighs around 3,200 lbs vs. roughly 2,600 lbs for your Superformance. It's the lower weight of your car that gives you the nod (at least up to around 120 mph).
You should look into putting less restrictive exhaust/sidepipes on the car for additional gains. |

I thought the 490hp of the f430 is crankshaft hp not rwhp. Don't most auto makers rate their hp at the crank? F430=490hp@3000lbs
COBRA=550hp@2600lbs
The F430 probably only makes 400 at the wheels however has traction control and paddle shifting. I am sure your car is making over 450 at the wheels because mine does and its a tweaked 427srtw. Superperformance 427IR= awesome ride brother!!!!

The F430s are about 430 corrected wheel HP and run about low 12s around 118 mph on a good day with a 1.8 or 1.9 60ft around here. |

Hmm, I didn't think that most SPFs were much over 2,400.

This is a bit out of the range of this specific thread but the last issue of Motor Trend did a comparison of the Porsche GT2, ZR1, Ferrari GTB and the GTR. Interesting read. Performance-wise the ZR1 did the best. One thing I found interesting is that when you are playing in this league, hp/wt ratio does not nearly tell the whole story.

I got into it with a 430 from about 30mph. I had 3 car lengths on him at 120 when I got out of it. Made him friggin crazy. Even crazier than his female rider who was screaming at him the whole way! 
Particularly delicious was he had the Prancing Horse yellow decals near the rear view mirrors and I had my Terlingua Racing Team Angry Rabbit decals in the same place!
