Clutch Fan CFM

[Maeda]

Anyone know what the stock clutch fan puts out CFM wise?

KA clutch fan preferably, although I don't think there's much difference.

it's hard to beat a clutch fan w/an electric one. In an fc wich is extremely similar, it puts out around 3500 cfm. I might switch back and ditch the electric.

Electric fans are good for stop and go traffic or drag racing. If your running your car in road racing conditions the clutch fan is a much better source of cooling. Stock OEM clutch fans can produce nearly 4000 CFM of air. Big gains in the stock unit.

You can only measure CFM of a clutch fan at certain rpm points. It's determined by size, blade length, width, pitch, and rpm. Seeing as a cluch fan is variable rpm, they aren't spec'd out like e-fans, which run at constant cfm, so all variables are constant.
Hope it helped. Since you're an art major, I'll re-explain in english if you'd like.
