570 hp at the flywheel what will I have at the wheels? Trans is a 400 with a 9.5" converter with 2800 in stall.
not according to this hot rod test they did a chassis dyno on a new zz502 400 hp 474 torqe that about 20% in my book it was a 4 speed also http://www.hotrod.com/featuredvehicl..._corvette.htmlParasitic loss with an automatic is usually around 20% + or - a few. With a manual trans its usually some where between 10% to 15%. So I will guess some where in the range of 425-450HP.
