The only reason I ran an electric fan drag racing was so I could shut it off and get the engine up to temp quicker....would be curious to see dyno numbers on both setups for comparison. Drag strip numbers don't mean much unless you were running back to back runs and could duplicate all the conditions, temperature, track temperature, barometric pressure, humidity, etc, etc....... I guess I've wasted my dyno money on lesser causes, might have to give it a try.
