First, I live in Minnesota, so not to many 90+ days. That said, even today at 89 degrees with high humidity, temp gauge straight up Noon. The mod in my opinion rocks! I'm new to the M3 (98) but I can definitely tell a difference before and after. Raced a Cayanne S (450+ hp), and we were nose to nose, and I don't know the first thing about racing. Anyway, as you can tell, I'm definitely pleased with the result.
BTW - I would say that fan weighs about 5-6 lbs easy. Bought all the stuff from TurnerMotorSports. I also switched to the Alum. Thermo housing, put in new belts, and flushed cooling system ( that one automatic with the mod )
Anyone else sides Kevin325 do this one as well?
