Mechanical Fan on S13, still have yours on?
Mechanical Fan on S13, still have yours on?
I was just curious as to who all has removed their mechanical fan. For those of you that have, did you put in an electric fan to compensate, or does it run ok without one?

If you re-wire the Electric fan to click on via a controller of some kind then often people in cooler climates can get away with it and it works just as good. I would suggest that you get a dual Electric fan set-up for insurance though, they arent that expensive. Removing the Mech. fan is about the same gain as the lightweight crank pulley, should be a little less actually.

why not use the a/c fan, just disconnect the power to the a/c compressor and turn on the ac when you need a fan or leave it on all the time. I guess this would work more for the people who use there car at the track more than street use

Re: fan
That sounds like a genuine alternative. Has anybody just leave the small A/C electric fan as the principal cooling fan?dankar wrote:why not use the a/c fan, just disconnect the power to the a/c compressor and turn on the ac when you need a fan or leave it on all the time.

What about changing the "propeller" of the A/C fan to a bigger one and eliminate the mechanical? I suppose that system already measures temperature and turns on when needed, so it would be a mater of leaving the system active, with or without the A/C running.

Oh hell yeah it's a great mod. Your car won't sound so much like a pickup truck with that whirrrr every time you hit the gas and the motor feels like it is more free to rev. But don't think for a minute that the little ac fan will move enough air to cool your engine unless you live in antarctica or something. I'm running 2 fans one 12" and one 10" with an adjustable thermostat controlling both. Use a heavy duty relay and 10 or 12 gauge wire. I found out a couple of weeks ago that 16 dosen't cut it. Car was running a little hot and when I popped the hood to check out the fans I was greeted by a flaming wire! :flamer :firedevil

Granted, I own an S14, but results still count =) I took my mech. fan out when I first bought the car a few months ago. I wired the electrical fan to a switch on the inside (fills those useless blanks in the center console) so I can turn it on and off if needed. Most of the time I just leave it running. The only time I have been turning it off is when I am driving on the highway. I've turned off the fan and let it idle for 10 minutes to see what the temperature would do, but the temp. gauge never moved (which is really only a Cold-Warm-Hot gauge if you haven't noticed). I don't know about power gains, but it sure sounds more like a car now.

Maybe it just me then. I need all the cooling I can get. I know that if my fans aren't working, my car starts to overheat quickly. Could have something to do with my driving though.
