ATI 15% lower on road course
I recently installed a ATI 15% lower pulley and got a tuned. My question is a road course on a 2 mile track about two times a year. I only go when it’s cool out. Like 80degrees or less. My question is. Is anyone having the supercharger overheat in these conditions with these mods on that M7 car ?
Or do I need to upgrade the heat exchanger and or an expansion tank? I would rather not but I don’t want to damage the car

Are you thinking that's from the pulley, what made you even change the spark plug wiring to MSD if your stock wiring works just fine. Stock wires go fine with the colder NGK plugs (do you have those in)?
I doubt your gaining anything from the MSD wires. That 15% damper you added is causing more spin which essentially converting to more heat throughout than your stock set up was designed for.
Short Answer: When doing any pulley changes, YES get a heat exchanger.

I just ordered a Weapon X expansion tank. I’m going to try this first. In theory it holds A lot more fluid so should take longer to heat up. Should be enough to last me through my sessions. We get a good hour to cool down
