Ive been told for thirty years that heat changes tolerance meaures and causes weakening of metals and uneven wear. if thats off then why does my car need fluid to heck with coolant its too expensive. are you saying an rc engine will run at 600 degrees with no failure?
The double tank method is unbeatable. Its the best way for sure.
The difference between running 320 degrees and 290 degrees is going to be negligible. Do you want him to rush out and buy a new engine just because he had a little high temperature spike? Jeez
320 degrees is not enough to hurt anything inside the engine. Period. Prove ThunderbirdJunkie wrong. With science, not a bunch of horsecrap spouted by ''experts''.
320 for a few minutes may not be enough to really
hurt an engine, but saying temperature doesn't damage an engine at all? That's just stupid. "Dispersion" is when aluminum expands when its annealed, and is then rubbed off onto other surfaces. This can happen at 300 degrees. The pistons in RC engines are generally a really hard aluminum-silicon alloy, which resists this wear, but it can still happen. Brass takes on a full anneal at about 450 degrees, but still softens enough to lose its shape long before then... which results in a lost pinch.
320 is too hot for one of these engines. Metal doesn't have to get to its melting point before it deforms.
