if i install a 11-1 high compression piston into my raptor what kind of gas will i have to run ?

 

I'd be running 110 or higher........

 

What??? If you run a JE 11:1 then your actual compression is around 12.3:1 or so. In that case you should run 104-110. If you have a true 11:1 compression piston like ross or wiseco, you can run premium pump gas at 92-94 octane.

 

i have a je 11:1 runs great on 93
