Panel, just out of curiousity, how did you determine if there was airflow ?
Or did the engine just run hot ?

Thanks,

Rob.

Got me thinking more about this. Check your cooling system VERY well for trapped bubbles. Any high point should have a stop**** to release air. As I recall, your cooling system wasn't too complicated on the water part, but if there is a vacuum lock, this whole thing could be just that the water isn't flowing around like it's supposed to. Not likely, but an option to your troubles.

Rob,
Had a buddy ride in the back and check airflow at speed. Nothing coming out of the floor, quite a bit from the side ducts.

Jason,
Did have a problem early on with air pocket but did a re-vamp and added a bleed in a trouble area.

The deal is, it is very stable temp wise, no spikes at all. At an idle, the temp is only 160-170. Every few minutes, the fans will cycle on then shut back down...just like they are supposed to. When you drive at sustained speed/load for say 10-15 miles, the temp will start to creep up and continue climbing until you stop. I have seen temps as high as 230 before I pulled over and let it idle for a few minutes. It is just airflow. Getting the right balance.

Airflow problems, need opinions...
 

Try this. Remove the front air dam and see how much air flow you get from the bottom of the car.

mike,

Can't Mike, it's all steel and welded on.
