Default Re: High compression head vs cooling

Combustion efficiency is only one aspect of heat generation. It is also affected by the amount of power that is pulled by the engine or how long it sets at idle. Cooling systems will draw the heat away if they are efficient but setting at idle has less air flow than running down the road. If you consistently pull heavier loads or try to get higher speeds than normal then more heat will be generated. With more power there is always more heat under load. Normal driving will have less affect and the difference may be negligible.
