james97gt Posted July 23, 2016 Report Posted July 23, 2016 I checked my compression yesterday on my 472 cheetah and realized I only have 150 psi. I have been running it on 110 renegade . Can I run this on 93 octane ? Quote
tfaith08 Posted July 23, 2016 Report Posted July 23, 2016 Make sure the jetting is right and start cutting it down some. Keep an eye on the plugs. I'd suspect that you'll be fine on pump and moderate timing. Quote
james97gt Posted July 23, 2016 Author Report Posted July 23, 2016 Does anyone know what the compression should be ? Stock cheetah head Quote
hercalmighty Posted July 23, 2016 Report Posted July 23, 2016 You really need to know what size dome you have. You also need to check your squish. Cranking compression isn't going to tell you what fuel to run. You have to figure out your copression ratio Sent from my VS990 using Tapatalk 1 Quote
