I know H22A's need 91 octane gas for compression reasons.

I live in FL and all we have is 93 octane. My question is: can I raise my compression to maximize the use of the 93 and still make noticeable more power?

 

err you don't need to raise your compression.

you just need to advance your timing a bit, and you need to do this with someone who knows how to do it.

and honestly, you won't notice a difference. 93 octane just has a higher combustion temp. 91 v 93 is same gas with different additives.

basically don't worry about it........cause there are more important things to do
