Paulie B Posted September 14, 2011 Report Share Posted September 14, 2011 How much can I increase the timing if I run race gas. Currently it's at +4 on pump fuel with 150psi compression. Thanks guys! Quote Link to comment Share on other sites More sharing options...
06specialedition Posted September 14, 2011 Report Share Posted September 14, 2011 Your mainly going to want to up your compression. I've heard 170ish psi or so to run race gas, otherwise it can hurt performance. Quote Link to comment Share on other sites More sharing options...

Wildcard will be there haha I heard you can do both- raise the compression and the timing. Quote Link to comment Share on other sites More sharing options...
papa_smurf49319 Posted September 15, 2011 Report Share Posted September 15, 2011 I was running 185 and 7 degrees, all depends on setup, some like 5 some like 10 Quote Link to comment Share on other sites More sharing options...

If you don't have the compression ratio requiring the use of higher octane fuel you will not have any performance benifit from it. The only reason we run a higher octane fuel it to prevent detonation from having a higher compression ratio. This is a common misconception with higher octane fuels. You gain the performance from the increased compression. In order for the higher compression to be useful it also requires the use of a higher octane fuel to prevent damage to the engine. Hope this makes sense. Your timing will depend on your current set up and will probably fall somewhere between +3-+7 depending on porting and current compression, etc. SP Quote Link to comment Share on other sites More sharing options...
