The screen needs to be big enough to flow good air but small engough to block the dirt. I like to use two layers of 1/4" screen off set. Then clean the radiator core out every week.
Two weeks ago it was 100* and dew points in the high 60's at the time of hot laps. Temp was still 85* at 10:30 after the feature. My motor was 190* after the feature. Eric
