Re: More hp with racing fuel?
Negative. Over a 120 passes (1/4 mile WOT) in a C5 Z06 with 100 octane vs the local 93 octane, results none. About 55 + passes (WOT) in the LS7 C6 Z06 used 100 octane last year until all gone. Put some 93 pump octane ran faster. It's gotta be a computer thing. For the money get the best local pump gas you can you don't need 100 octane especially if pretty much stock like me. Keep in mind I don't race on the street much less drive the LS7 on it only the strip 5 miles away. What else can a drag racer ask for? :beer:
