Thanks for the replies. Here are a couple of pix of the rig. Not a ton of airflow through the rad but remember, the speeds are a lot higher than on sand or dirt. Between 50 and 100 mph the whole time the car is on track. I will be installing a belly pan to help reduce the tendency for air to come up under the car and push the wrong way through the radiator.

Car weighs at most 1400 wet w/driver. Tires are 195 50 15. Front drive.
