To Lead or Not to Lead

Using 110 octane on a 93 tune is similar to dialing timing back, and it will make less power.

4Gallons Toluene+ 1Gallon Mineral spirits + 16oz Marvel Mistery Oil = 117 octane unleaded race fuel.

It makes sence. But the higher octane with my present (93) tune does make it run smoother with less backfire/gurgle. :dontknow:
I've PMed Sean Roe about a more aggressive higher octane tune for racing.:rock: :rock: :rock:



I'm going to try this in a friends mustage, I may use Seafoam though.

I'm still reading but...:marchmellow: :marchmellow: :marchmellow:

Toluene can be used as an octane booster in gasoline fuels used in internal combustion engines. Toluene at 86% by volume fueled all the turbo Formula 1 teams in the 1980s, first pioneered by the Honda team. The remaining 14% was a "filler" of n-heptane, to reduce the octane to meet Formula 1 fuel restrictions. Toluene at 100% can be used as a fuel for both two-stroke and four-stroke engines; however, due to the density of the fuel and other factors, the fuel does not vaporize easily unless preheated to 70 degrees celsius (Honda accomplished this in their Formula 1 cars by routing the fuel lines through the muffler system to heat the fuel). Toluene also poses similar problems as alcohol fuels, as it eats through standard rubber fuel lines and has no lubricating properties as standard gasoline does, which can break down fuel pumps and cause upper cylinder bore wear.

That rings a bell.....Based on that I would rather run the leaded (if no unleaded is available) and just replace the O2 sensors every 2K-3K miles...
