He runs a mix of Nitro, Meth, and Toluene. I turned him onto mixing the Toluene in a couple years back. It helped him stabilize his mix quite a bit.

I'm betting 97/98 octane will suit me just fine with no benefit to running fully 100.

For those wondering what mixes will net what octanes, I have a spreadsheet to do the calculations at WCBF with no error for both two different octanes of fuel, or any octane fuel with Toluene.

I do have 3 questions - what about octane boost like NO2, 108, 104 or even grease lighting octane boost additives. 1. Do they change boost the points from a 93 octane point to 97 or even 100? 2. What ingredients do I look for without ruining my injector seals and other components. 3. What would be the best brand to use in our Series 1 engines.
