Inliners International Forums General Discussion Bench racing Ethanol, E85 for fuel ???

So they were using an alcohol & water mix to keep from overheating.Very interesting.

I remember back in my youth a buddy had a 13:1 motor he ran on the street and he was using an alcohol & water mix to keep it from pinging,it was hooked up to a vacuum line.

I read that motor build a couple of days ago.

I was looking at pistons at the autozone site and they list LPG pistions for the 250. Speed-pro I think.

So by raising the compression 2 points the gain is 8% power. Is the 7% mpg + or - ?

Is this using pump gas or E85 ?
