my single t88 camaro made 1021 rwhp on pump gas. Hennessys vipers were junk. Ps...i own an srt10 as well and an 08 z06.
what was you engine ... didn’t u get detonation from pump gas???
How much boost u were running
and where did u modify it ... any pix???
teh viper has a does pretty well ... keep in mind it can still go more but they are trying to keep it dont to make it durable … if u stick the car to the ground it will go over 250mph easily
one of my friends has a Skylien (R34) that puts over 800hp on the street with a T88 … uses 1.7 bars .. but can go up to 2.3 bars (with race fuel – 114 octane)
1 bar = 14.7 psi … do the math
