there is no such thing as 'power-robbing heat soak'
engines work by in-cylinder conversion of heat into work
the amount of alcohol that can burn in-cylinder adds more heat in-cylinder than does the equivalent amount of petrol
roughly 5% more with ethanol and 10% more with methanol
it's simple chemistry
that's why 'they' use methanol
that's how methanol gives about 10% more power without any increase in the CR
people should get this into their heads
the methanol engine should have the same gas temperature pre-spark as should the petrol engine
cylinder cooling was generally reduced for methanol use eg the JAP speedway engine that won about 20000 races
yes even if cylinder cooling wasn't reduced power would still be better - hence the 'cool is good' myth
usually methanol is overfuelled because the jets had anyway to be huge ... and ....
methanol's much wider explosive range allowed/encouraged far more over-fuelling than would petrol
