It's 400 plus shipping from zzp, cheapest place I found it. If you look around you can find pure methanol for 4 dollars a gallon then dilute it with distilled water to 50/50. Wasn't hard to install.

I'm on a 3.0 pulley now with the methanol and e85, will be dropping pullies soon, have a 2.8 on order and a snout machine tool coming.
