on my autocrosser, i would like to eleminate the weight of either the electric auxiliary fan or the mechanical one with the clutch. does anybody know how much cooling each affords? i would want to keep the one which does more cooling.

logic says to me that the mechanical fan does a lot more by the size of the blades etc.
