I recommend a 50/50 or 75/25 mixture you can make into your own it’s pretty easy but 100% your asking for trouble or shall I say problems! I can’t remember is your motor built if so you are good!
Screw that methonal. I hope they at least mounted the meth pump / and reservoir in the rear of your car so that you won’t have problems. Meth has a boiling point of 147 degrees and if your pump / reservoir is mounted in your driver fender your gonna have issues because the engine bay gets wayyyy over 145 as you know. Port injection would have be more ideal and you would have been able to run 85% ethanol vs that blending crap. Shit ppl don’t tell you bro just trying to help
