Mechanical fan to electric fan

[Silver-Arrowz]

I'm contemplating changing the standard fan to electric fans. I know that there is a few KW to be gained, but I was wondering if this helps the cooling of the car better.

From what I've heard, at low speeds it is better, but I'm more concerned at high speeds as I use it frequently for the track. What do people know? Has anyone done this before? What are the results like?

At high speeds the air speed is usually enough by itself, the fan 'draws' the air through the radiator.

I think the stock fan is a fluid clutch style and these aren't supposed to operate until you reach a certain temperature, most I've seem work all the time tho' cause they are knackered. The clutch style fans are good when they work. Davies Craig make replacement ones I think.

If you do go the electric style make sure you retain the cowling and put it in the same position as the old fan.

I've put a Davies-Craig DCSL14 on mine. On the track, the engine does get quite hot, but I suspect that's the result of some dude at a radiator shop NOT pulling the radiator apart and checking it, like I requested after I blew a head gasket (sod charged me $40 to paint the fn thing with black paint:mad: ).

I'll be getting it checked out properly in the next week or 2 - I'll let you know how it changes things.

That doesn't sound good. Dodgy Bro's radiator repairs.

Let us know what the results are. Either I'll change the fan (not likely cause some people on SDU don't recommend it) or get a better water pump. The radiator has already been upgraded to a bigger item.

Not Dodgy Bros, but part of a national chain of radiator repairers.
