I think what you guys are failing to remember is that ZO6's with competent drivers run in the mid 12's around 115mph! Be it a roll, a stop whatever....If drivers were equal, the ZO6 would/will win......
Burrita....stock ZO6's commonly dyno in the 365whp range.
I personally have put a pull on a 6spd C-5 with 8psi on the t-28 which has trapped nearly 108mph for me...We went from 40-120+(middle of 2nd to top of 4th). Needless to say he was astounded that a 4dr just gave him a taste of haste!
Burrita...I think you just need to work on your traction/launching issues. More power will make the car faster, but will it make it quicker?
