hi guys new to honda tech so please be easy if i mess up... but im currently putting together a build bottom end f20b. and i do have some questions.. im doing a bizzy built bottom end and planning on sticking with the 11:1 comp pistons, in turn im running low boost. i was thinking 8-10psi at max! i was wondering how do you know when race fuel is needed???... id like to stay 93 with maybe octane booster if needed. can any one give me some light to my question?

 

When you stop making power lmao but seriously that and your knock counts go up amongst other things.

 

Race fuel will be needed when you can no longer tune out Detonation.

 

hmmm i really wish we had a e85 pump around me... i wonder if any one has done a high comp low boost build and ran 93 and was happy with it..
