Yes, you can run methanol BUT it's not easy to do.

First of all you will need to at least double your injector size as you will require 2.2 times the amount of methanol as petrol per cycle.

Secondly, you will need to replace the WHOLE fuel system as methanol is highly corrosive and will literally disolve the lining of your fuel tank, fuel lines and all the seals/o-rings within.

Thirdly, methanol is toxic, so obtaining it, storing it, handling it etc. can and in most cases, will be difficult.

To give you an idea, a 900+bhp Evo 4G63 engine on methanol was approaching 90% duty cycle on 8 1600cc injectors whilst running over 40psi on a T88 Giken turbocharger - that equated to a 20 litres of fuel consumption per minute at wide open throttle!!!
