After 1.5 yrs on a old whipple system running MEFI-1 electronics, the guy that built the motor & whipple system did not put a thermostat in it.
So consequently it see's no real heat in the engine. 100 degrees at idle & 125 degrees after running it hard, is all she will build heat wise.
I come from the old school where heat helps build horsepower, so whats your guys oppinions.
