(100 octane)Fuel question

[unit213]

I've used about every mix of race gas and 93 octane without my a/f ratio hardly ever changing at all. Or it's never changed enough to make an adjustment in the tune.

Call me crazy lol.

Agreed. I run a mix of 110 octane and 93...have for a long time now. No issues what-so-ever and the car runs very hard. It's tuned (very aggressively) for 93. The extra octane keeps the internals...well...internal.

Did I mention I am building a new motor.:dw:

It wasn't because of that though.

I read that.

What's the plan on the new set up? High compression?
