i am going to get a wiseco piston with a compression ratio of 10:25:1 and some people say that 93 octane fuel will work fine and some people say that it won't, can someone please tell me what is true. I don't want to have to use an octane boost if i don't have to. thanks.

 

I had a 98 warrior that i put a 10 1/4:1 piston and a .390 cam in it and 92 or 93 octane was fine. I don't think you'll have to worry about octane booster unless u put either a 12:1 piston or a .450 or so cam.
