My water gauge is never as hot as 215, but the fan keeps the car at about 200 or less when NOT MOVING forward. It could be better like your number.
The manifolds are doing well but I need to get to the dyno to provide numbers that can be believed. I need to document the value and gain if any, though the car runs well since I did it. Iam remiss in doing my homework, but I am having fun while goofing off. My wing was a distraction too, but Carlisle is once a year.
