All right N2o guys need a little help. piston ring gap for a 250 shot on top off a 700 HP BBF running on E85? I lifted the top ring land off of two of my pistons last trip out with only a 125 shot second pass boom. My ring gap on tear down was set to .028 too small this was the top ring. I was thinking .008 X the bore size to play it safe when i put it back together and about .002 larger on the second ring? What do you pro N2o guys think. I i'm sprying with E85 not race fuel.
Thanks in advance
