The crank horsepower number is a rough estimate. Its pretty simple. The car came rated at 426 fwhp. Most LS3's are making about 365 (average) at the wheel. So if you do the math thats about a 15% (14.5%) drivetrain loss. Now when the fwhp is at 842 and you subtract the 14.5% for drivetrain loss you end up with 122 hp and that equates to a rwhp of 720. So Ray's car may actually make more at the crank. Just becasue you are making more fwhp the % of loss still remains the same. Hope this help.

Regardless, the car looks slow and I will be abusing him at our local track soon! Ray, Another rental on the 18th of June. Maybe Ted will loan you a $100 after you pay him so you can go!
