so with that in mind, engines make more hp at a "given" temperature, so has anyone dyno'd a bare engine's hp, then painted it and dyno'd it again for comparison ?
just for example, a new hellcat has a high temperature thermostat, while most here worry when the temperature on an older muscle engine gets to 190.
myself, i don't start to worry until i see 235 or so. [provided of course, the engine is built right with quality components]
am i really crazy ? [wait, don't answer that ! ]
