my freind is looking at getting a set of hypertic pistons (speed pro) pistons. like around 11:9 or 12:1... he was thinking about spraying a little nitrious through it to. .maybe like a 100 shot? well he talked to a guy at summit and he said you could spray a 100 shot on the piston and have no problems>>?? but i heard you couldnt with these pistons.. so i called a couple other places for him to see what other people say and its about 50/50? what you guys think?
