u can buy nitromethane from snow performance(
www.snowperformance.net) they recocomend a specific mixture or else you'll lean out. im going to run a straight water then rpm switch over to another container of whatever the ideal mixture is of the nitro for when my cam gets into powerband. probably better on the tires that way.
methanol can be found on e-bay at a slow trickle 28 dolalrs for a gallon plus 16 for shipping an explosive substance. im not sure if tis technically allowed to be sold on ebay but ive bought worse.
