Do you by chance have the timing down low? You need 36-38* driving around when your not under boost.

just a little something..do you have a mechanical water pump? if so, what are the pulley diameters? a lot of times we put underdrive pullies on to get the rpm right at wot and it slows the flow a lot at low rpm. do you have a thermostat or atleast a restrictor in the intake? could be also runing really lean? ..good luck!

How well is the tune? Mine would run 190+ after the burnout and get to 210 after a pass on teh track. In he driveway idling, it would see 180-190 easily with fan and water pump on.

It was rich so I dropped 4 jet sizes in the primary. It runs 160-170 in the driveway and after 3 passes Sunday, never got over 175*


Being a blower car, is it maybe a little too fat?

I know its probably a simple Idea, but I had one of those nice aluminum flex fans at first.
Damn thing drove me nuts trying to figure out why it was over heating. put in a new Griffin alum. Rad. redid the shroud, and it turned out to be that Damn fan. Put on a stock looking full bladed fan, and no problems now.

Has anyone tried the reverse cooling method? A friend of mine runs this on his 69 Hemi Dart and it wont go over 175*
