100% Meth is on average 115 octane.... soooo given our tanks are 19 gallons so we would need approx 3.8 gallons of meth mixed with 15.2 gallons of 93 octane to reach close to 20% methanol mix... the resultant octane would be somewhere close to 98...
Considering we use meth already to offset the fuel right now.. sure we can handle it... but I believe it's better used as a spray through the intake manifold for a multitude of reasons...
