Fan clutches

[Roy]

Now we are getting into the warmer parts of the year, im looking at engine cooling. Has anyone previously removed their std fan and clutch only to replace it with a complete electric unit.

I was looing at the Davis Craig electric water pumps and electric fans. I imagine your car would run cooler on track and eliminate a lot of load placed on the crank by pulleys/cfan clutch. Not to mention i imagine the whole setup would be lighter.

With minimal amp draw you can even set these things up to continue to circulate coolant thru your engine after you have shut it down!

Any web link to look at ?

Plus looking at engine bays of track cars, big hp cars you never seem to see the factory fan and clutch. My car though reasonably stock was getting some serious heat soak at the track.

Yes, I've put a DC thermo fan (DCSL14) on mt GTS4. It is triggered by the A/C fan which in turn is triggered by the thermal switch in the bottom tank of the radiator.

I find it turns on at not much above normal operating temp. On the track, I've found that the engine actually overheats quite significantly. This may be due to the FMIC blocking air to the radiator, rather than the fan situation. I suspect I am going to have to get a couple of extra cores fitted for summer. And because of space restrictions, the fan has to be mounted and operated as a 'draw-through' rather than the more efficient 'blow-through'.

The power gains are apparently minimal.

I have found the standared clutch fan and assosiated assessory's are very efficiant at keeping appropriate temp, with

out 2 much tax on the overall power avaliable.
