there have been no detrimental effects on the car; the engine heats up just fine; there was little difference that I could tell. I have an Aeroforce Interceptor and can read engine temp, it heats up pretty fast.
I suspected there would be little to no difference. The coolant system operates on a thermostat, so the oil cooler wouldnt begin to make a difference until the engine got up to temp and the t-stat opened. Thanks for the confirmation - I think I'm gonna pick one of these up.
