Author Topic:   Converting a gas engine to alcohol
posted June 13, 2003 10:48 AM
I'm running a Chrysler Le Baron in our U-car class, and I was wondering if it was possible to convert the gas engine to run the high octane racing fuel without having to spend a ton of cash. It is fuel injected, can the injectors be converted too? Someone please help!

I am confused. ARe you talking about switching to methanol fuel or high octane race gas. There is a difference. I doubt you could actually run alcohol without redoing a lot of stuff. You have to burn about twice as much alky so your injectors and prob fuel pump wouldnt be able to keep up. Race gas you might be alright with as long as it doesnt hurt your injectors or deteriorate the seals in your fuel lines. That being said i dont think you would see a huge power difference going from pump gas to race gas unless you have modified your engine internally and corrected the computer to compensate. The alcohol you prob would feel a difference but once again pretty much out of the question.

I'm sorry, I was thinking one thing and typing something else. I will be running race gas, not methanol. We have done internal motor work, it has been overbored .030, as much as the rules will allow. Sorry for any confusion.

You'll want an open loop software system if you can find one or the thing will run like crap cause it will fag out the O2 right away on leaded. You could try a 100 octane unleaded, but you'll only see a benefit if you up the compression or timing somehow.
