Alcoholic K5

Be Prepared to rebuild often, but smells killer.

Ever run VP Fuel thats oxidized? Everyone I race against runs the stuff and it smells nice and aparrently works well. You even catch wiffs of it like 2 hours after the race. MMMMMMMMM!!!! :mrgreen: Is that alcohol?

Talked to a buddy, who is former pro, and he says Methanol is what you want. You need to use exactly 40% more fuel. So whatever it takes to jet out 40% bigger than you are now. Also, interesting factoid: Alcohol or, I guess Methanol draws moisture. It will draw moisture in and then the fuel evaporates, leaving you with water in the crank. Obvious problems, there if you leave it. They drained tanks, put pump gas mixture back in, ran it for a few minutes and then shut them off for next race. He said that when doing that they ran like crap, because they were jetted for Methanol.

Cheers for the helpful info guys, a few more questions: If i buy a 44gallon drum of methanol will i have any problems with it going off or absorbing moisture over a few months? Also what sort of rebuild intervals would I be looking at?
YUNGGUNNAZ:
if you decide to go the alky route call packard racing and have him set you up with his 44mm hv carb with the adjustable power jet.he'll give you a starting point(usually 2.48mm i believe).opinions vary on how often to purge system.just pull down a banshee on alky thats run just 5 races,purging after each.cases look like tarnish from alky and moisture.use either maxima 927 or klotz super technicplate.NOT R-50!!just my 2 cents of thought.
