I think Chevrolet is being overly optimistic about the performance #'s for the new 500 HP Z06. They are now saying it will do 11.7 @ 127 MPH. I cannot imagine it will MPH like that. 300 lbs will not add 5-7 MPH to what a 450 RWHP/500+ RWTQ headers, exhaust, no cats GTS will run in the 1/4.

I am guessing the new 500HP/475LBSFT Vette, with it's slightly longer powerband, ie 7,000 RPM redline, will be a pretty even match for the 450RWHP and 500+ RWTQ GTS. The old Z06's just got killed by that type of car no matter what the Z06 guys would like to believe in their little fantasy worlds!

GM finally stepped up to the bigger motor after all this time of getting spanked, now I think DC must up the ante with some type of factory supercharger or turbocharger system and put the Viper way ahead of the game with 650+ HP and TQ. Just my .02.
