I just don't see how spraying a higher octane fuel that has properly sized nozzles and a reliable pump can't be consistent or provide gains. I know a member locally that uses meth and gained about 23whp to make 356whp iirc on his gen v IC build. That member later on also told me he actually had a smaller nozzle in his pre-blower setup than he thought, so he put a bigger nozzle in it an was able to drop down a pulley size. So obviously he could have had a better dyno run with it. Most of the time, when people complain about meth, they had no idea how to properly utilize it. I know a guy with a vette, had meth and hated it. Took it off and made more power without it. Then my other buddy, who owns a stealth, sprays meth like a champ and is putting down close to 550awhp on a stock engine with modified stock turbos.
