Overheating race car

That shroud is KILLER. I love it! HOW MUCH?

As stated before your 1250 cfm is a joke. It is for a trans cooler not a engine. You need a 2500 cfm fan or bigger.

Flex-a-lite makes a awesome fan called Black Magic X-treme. It's a puller and flows 3300 cfm. Looked it on Jeg's and the part#400-180. Father In-Law has one and when he turns it on you can really feel the air move.
