So I have 25 gallons of 101 race gas I need to burn up. I was thinking of mixing 50/50 with 92. Cecil said I should see slight increases. But seeing close to 18+ psi already, would I really notice/see any gains? Otherwise I have no other need for all this gas laying in my garden shed ha..ha.

Is it knocking?

How old is the gas? Gas does have a shelf life.

You will pick up a few more HP with a power tune for that higher octane fuel. Without a tune, I doubt you will see a measurable increase in power, unless the engine was already at the knock threshold. That said, if I had some fresh 101 octane laying around, I'd dump it in there.
