Where did you get those #'s? That is incredible for a factory engine!! A pulley swap and a flash would put that thing over 700 RWHP easy.

from an inside source with a few personal contacts with in gm. last year he also stated the 08 c6 would have 450hp. although the official rating for the 08 c6 is 436 i believe most are dynoing right at 390-400rwhp. this is very close to the 450 that he reported 12 months before the 08 came out!
the 663 was also confirmed from a independent source within the media community!
i also want to say this 663 dyno will not be the production tune. this dyno was done during a test and tune session and i believe the tuning and engineering of the car is still on going. i do not know what boost gm was running during this run. just saying the zr1 should be capable of these numbers on the stock blower!
