Yellow Cobra said:
I think the horsepower gains from the supercharger are about the same for both cars. Ford over rated the HP on the 2001 Cobras and they under rated the HP on the 2003s. The stock FWHP for the 2003s is at least 425 and the RWHP is 360-380.
You are absolutely correct about the HP ratings for the '03 Cobras YELLOW COBRA.
Ford had to under rate them for insurance reasons ect. Just like back in the 60's and 70's with the HEMI's. The HEMI was rated and 425 at the flywheel, but it was more in the neighborhood of 500+.
I'm a Ford Employee, but I work at a Visteon Plant(Thanks UAW!
). We have a dyno here at the plant. Everything from Minivans to Superduty Diesels gets run on.
Back before the S/C Cobras came out, I was talking to one of the guys from Experimental Engineering who just finished doing a few pulls with a '03 Cobra and I asked what #'s she gave. He showed me the print out and it read pulls of 385,383,392 and 389 RWHP!
He said that they did some test at night, with lower air temps and the #'s were in the 390-395 range.
He also told me of runs that did with a S/C S281. The results were in the 330-340 RWHP range.
You have to ask yourself the Question which one you want to spend you hard earned $ on. Personally when I do the math it makes a hell of a lot more sence to me to buy the S/C Cobra, which makes more power and costs less than the Saleen.
Why not buy a MACH1 and Supercharge it?????????????? Think about it 4.6L 4v, Solid rear axle,31 spline limited slip.
What ever you decided buy what you want to buy. As long as it's not a ***GOT Foreign P.O.S. Tuner Car!
