ok buddy heres what happens. higher nitro content will make higher temps with an exception. when you get higher nitro content you can run the engine richer. since nitromethane can burn without oxygen(partially because it has oxygen in it) you can richen the engine and get more power, also you get more oil which cools the engine more. sorry i made the mistake of saying your suposed to lean it out in my previous post. since there is more nitro content and about the same oil content then there must be less methonal content. the methonal is the reason you need oxygen, so less methonal equals less oxygen. and you say it doesnt produce more compression? explane to me then why people detonate engines with higher nitro?
