trickedcarbine Posted October 29, 2012 Report Share Posted October 29, 2012 I was gonna be a dick and just say oh..... 225 kicking psi. But I will give an honest answer that makes you think a little. 13.0:1 static compression ratio is about the cut off in my opinion. Maybe 14.0:1, but any higher and you need good true race fuel. Learn to calculate those ratios from your current set up and let us all know what size domes that equates to Quote Link to comment Share on other sites More sharing options...

BigRed350x Posted October 30, 2012 Report Share Posted October 30, 2012 Whats your end goal? Why do you want to run race-gas? The engine setup and compression and timing and dome design determine what fuel you need to run. Give Kevin @ Herr Jugs Racing a call. He can go over all of that with you and get you an engine setup that does what you want. There isn't a single answer to your question. There are a lot of variables that need to be determined before you move forward. -Jared Quote Link to comment Share on other sites More sharing options...
