Yesterday had a nice test of nearly an entire 1/4 mile run. I wanted to get some data from a longer run at wot to see if the 20psi modified cap would keep the push to a minimum.
Well, at times i saw over 22psi and did see it flutter, to indicate the cap lifting .
Today i checked the coolant overflow and it was higher than normal.
I have an appointment with a shop to help price out a custom radiator. I'm anxious to see what they think. Especially since i didn't tell them its for a dodge caravan!
