Are you all running high octane fuel aka race fuel? Is that all the time, or all you mixing with the lower octane at the gas stations?

Several posts back, there was talk about alcohol being used to boost the octane. What about octane booster?

Running 6 psi on my t/c 97, pings/detonates on pure 91. For those t/c, let me know how you got around it using pure 91.

TIA for your replies/answers.

most people are running either 93 or sunoco 94, tops with more than 6psi. Sounds like your leaning out if your only pushing 6psi!

 

What is your setup, what spark plugs, fuel injectors, piggybacks are you using?

 

I just use regular premium gas which is 92 or 93 octane!!with 1 step colder plugs.

 

With a J&S Safeguard you could run 87oct on high boost. You would loose power from the timing retard but it would run fine
