bansheeman95 Posted April 4, 2004 Report Share Posted April 4, 2004 you would probably need to run at least 93 with 19cc domes, you could run 91 with 20cc domes, i recently switched to 17`s and i run 111 octane. I still have a set of 20`s that i only ran for a year if your interested. good luck. Quote Link to comment Share on other sites More sharing options...
