Considerations for converting from gas to methanol for motorsports:
Methanol is corrosive. Fuel systems need to be upgraded to corrosion inhibitive components not necessary in fuel systems for gas.
Methanol requires approximately twice the amount of fuel for the same power level as gas. Fuel pumps and jetting need to be upgraded for the higher volume.
Methanol has a higher heat of vaporization. That together with the increased volume can condense the inlet air, increasing the weight of air into the engine. That together with the proper air/fuel ratio will usually increase engine power. A power increase as high as 10% is reported by several racers who converted to methanol.
Methanol cooling throughout the intake system of a drag racing engine may eliminate the need for a cooling system that would otherwise be needed for gas.
Methanol is widely available throughout regions where racing is common.
Methanol absorbs moister. For long term storage, it should be kept in sealed metal containers. Methanol in plastic containers may get contaminated from humidity from long term storage. Plastic at the microscopic level is porous and will let moisture in.
Methanol is poisonous in all forms. It should be handled with protective clothing and eye protection.
