is 11.2:1 compression too much for 91 Octane

Is there any way to easily up the octane of 91? haven't heard many good things about octane boosters... but haven't really looked into it either.[/QUOTE]

It works. I have gone through 6 cans in the last year.

Call them yourself if you want more info they are die hard racers and engineers.
