Man, there is a chemical blast from the past. Didn't know it was still being considered or used. We used to run this with our briggs karts along with all the other chemicals we could get out hands on. LOL

We could only use about 10 cc per gal on gas motored 2- strokes. Alky would stand some more. P O builds heat in a hurry. Used a bit more in the Briggs, that is until we began using 60% nitro in our stock appearing Briggs. Man you could feel the exhaust pulse at idle 6 feet away.

The reason I'm asking is all I've heard of it being put in is karts. Didn't know if there was an advantage over nitro methane in a stock car race engine.

It's an oxygen carrying fuel,you better have some good parts,i knew a guy who blew 3 motors in a row in a car he bought that had a blown motor when he got it,problem?propylene in the tank,must have been 25% or more! nitromethane will not mix with gas only alky.

I know of several guys in my area that have or are currently running it. One thing that makes it somewhat easy to spot (if your tech guys are worth anything) is that it makes the exhaust burn your nose and eyes like nitro if you run it real rich.

Rico, I'm not so sure the propylene oxide was the cause of the blowed motors in your friend's ride. This stuff evaporates very quickly, even when mixed with gas. If someone is going to use it, be sure to mix it as close as you can to when you'll be out on the track.

You also need to jet a little richer to account for all the extra oxygen.

Thanks...I found a guy that sells it premixed with track gas. I guess I'll give it a try.
