To borrow a phrase often used in another forum.....Irony meter pegged!

How do you know exactly what he meant by "rich"? It's a known fact, although apparently not to you, that methanol, and particularly nitro, have a wide range of air/fuel ratio where they both deliver high power. So he likes to run it rich...more fuel to give more internal cooling to increase the density of the air in the crankcase which in turn will add some power. Works for me.

Making the engine cooler than ideal? Tell me what the ideal temperature is. Cooler than "ideal" eventually causing wear to increase? Why eventually? It either increases or it doesn't. How come I can run an engine in a 4 stroke and it'll last practically forever? It seems you don't know that there's very little difference in temperature from even the 4-2 break point to slightly rich of full peak.
