==Potential gains== A law of physics states that for each 10º drop in air temperature going into the motor, power will pick up by 1%. This is because when the air is colder, it is more dense and therefore contains more oxygen. So potentially, a 100º drop in air temperature would equate to a 10% increase in power. On a 400 hp motor, this would equal a 40 hp power increase. Of course, a tuner would have to compensate for more oxygen by jetting richer to correct the air/fuel mixture. The later model EFI systems sense more oxygen and automatically richen the mixture. [[Category:Engine]] [[Category:Carburetors]]
