CorradoVR6-n.o.s 0 Posted November 19, 2008 Report Share Posted November 19, 2008 I ran 300hp on my on a later three layer gasket,so that ratio was rased to 10.5.1, and ran with no problem.It was intercooled,i suspect an non intercooled with higher intake temp would not fair well. so a mild drop in CR,say 9.1 would be better .
