I just got off the phone with my local speed shop to see if I could get some race gas. They have 114 octane, but it's leaded!
They told me that it doesn't have much lead in it and it won't hurt anything except it will clog up your cats. I don't have cats, so that's no problem.
Any of you run leaded race gas in your 7's?

 

Leaded fuel will kill an O2 sensor, in nothing flat. Call, call call. Unleaded race fuel is becoming more and more common. The tree huggers have struck again. Try to look up Trick, Unocal, Cam2, Turbo Blue and Torco online to find a number for distributers. Sometimes the oddest person sells or can get race gas. Unless you're in the middle of nowhere, there's unleaded near you. What kinda mods you running to need that much octane?

Found some 107 octane unleaded.
They also had race grade methenol! Hum????
Anybody tried that?

 

Methanol (alcohol) is a definite NO-NO! Engines that run methanol are purpose built for the fuel. A methanol engine will burn nearly twice as much fuel in a given amount of time as a gasoline engine. What this means is you'll be seriously lean. I'd guess the thing might not even run at all. Methanol engines run quite a bit cooler due to low evaporation temp of the fuel, but there's that pesky thirst issue.
