i will say, the last time i was toping my car out, around 130. i did it a few times on that stretch. the first time i did it i held it for a little while because i wanted to see if it would pick up anymore, i then slowed down and did it again going down a slight hill, got up to about 125 then it starting slowing down pretty good. im sure it was knocking like hell. if i do go at it again (probably wont tell i can atleast see if im knocking) im not going to stay at the speed or try and contuie to go faster. im sure it does goes lean as hell and knock a good bit. also oil becomes very videl then. with the crank spining like that and sliging oil everywhere, im sure things are not getting oiled like they need to be.
