You won't get anything like the full benefit of methanol unless you raise the compression a fair amount. But if you go on to use some percentage of nitro, you don't want all or maybe any of that added compression. In either case, read up on the hazards of methanol (poison, don't get any in your eyes, burns with an invisible flame) and nitro (explosive, can auto-ignite and leave the engine running even with the ignition system switched off). Mike's alternative ideas sound wise. Alky and nitro are wonderful racing fuels, but expensive and a pain to deal with in a playboat.
