Simple question, does a 102mm 11-1comp piston require Race gas? I wasnt sure if the piston size is what makes it require race gas or the Compression.

Thanks

Piston size has no effect on choosing octane, unless it raises the compression levels. Having a huge piston would mean squat unless you got the compression to move it and the octane to ignite.
The limit for pump gas(91-92 octane) is about 160psi. Any more then that and you will need to step up the octane.

 

Thanks for the input, Exactly what i needed to know.
