Interesting post, though heat is a byproduct of friction, and in an environment like an IC engine, there MUST be friction for the engine to function. It's a terrible idea to rev an engine past 10k rpm in neutral (for high revving engines) due to the fact their is less mechanical tension on the … View Video
