fastrthnu Posted April 20, 2009 Report Share Posted April 20, 2009 Used to be able to find one, Im possibly retarded maybe, I cant find one. Sea level I need to figure out what 182psi is converted to CR so I can figure out what octain to use. And Im not even sure that is my reading. That is on a new top, 12 kicks with no pipes and just reeds on. Prob like 11:1? I wanted to keep t pump gas but fk it. Ill end up prob running 98-100. :geek: Quote Link to comment Share on other sites More sharing options...

fastrthnu Posted April 20, 2009 Author Report Share Posted April 20, 2009 yea, I found one of those, but thing is dont know my chamber volume and my crank is +4 so my piston at tdc is higher than the deck. Somewhere there was a relative calculator that would tell you about what your cr was with your psi. Quote Link to comment Share on other sites More sharing options...

fastrthnu Posted April 20, 2009 Author Report Share Posted April 20, 2009 nm I found the calc its 12.3:1 so I guess VP red 100-105. That sucks. Quote Link to comment Share on other sites More sharing options...
