I have a clean good working stock radiator, with a black magic 2800-2900 CFM fan



man that thing is a workhorse, in the two years i've never had any problem, and the adjustable thermostat is an added feature. It really makes me curious though, what is the highest/peak CFM you can possible get from a "clutch fan" no where near as high... really
