    Also if you want to run your aux fan after the car is off you can just turn the electrical back on. If the temps are high enough it will run until they go below the temp sensor rating. This is also assuming you don't have a light weight battery as it could drain it too much.

    Three questions:

    1. Does anyone have a DIY (or just know the best way) to wire the fan to a manual switch down by the dash light dimmer switch or something?

    2. Does anyone know offhand what the max depth a fan can be and still fit?

    3. Is the "mounting kit" that Bimmerworld sells sufficient to mount these fans properly? I see many of you have other rigs.

    Thanks

    not sure how you could turn the electric back on, and have the fan still turn off, and not drain the battery?? the electric would still be powered...????

    my aux fan after a hard 30 minute track session, turns off before I even get back to the paddock at a slow crawl through the hot grid, and back into the paddock area..... and I have mine set for 80C kick point with 90 degree ambient temps... not sure how the fan would be running for more than a couple minutes TOPS at idle to cool everything down and turn off...

    Question:
    I will be upgrading my rad to the new Carr Industry aluminum unit. It's a bit thicker than stock So my question is would running a pusher fan (on front of rad) be as efficient as running a puller? I don't have the aux fan, it broke awhile ago and I just took it off. There is no AC condenser in the way, but there will be an FMIC where the condenser was. I just don't know which would be better a push or a pull. My guess is there won't be room for a puller with the CARR aluminum rad.

    Sorry if this thread is old, I just found it.

    Has Carr told you when they will have the aluminum expansion tank available? They told me they were trying for this summer, but there was a delay. They were going to have a radiator, the aluminum expansion tank, and an electric fan as a set.

    Because it's temperature controlled, which you already know. Try it and see.

    It will only run for a few minutes before shutting down.

    the radiator will go on sale within a month, everything else has been delayed irrc. They have 3 of the rads in and are testing one on an FI car, one on a Track car, and the third on a track/street car. Once they are done with testing they will start selling. I didn't know if the fan in the eventual kit is going to be push or pull. It may be pull since most people still have their aux.

    carr has been selling that alum radiator for a while now. I've installed two of them in my friends car's... they are STOCK size and a puller fan will work fine with it. no issues, as I reinstalled the stock fan shroud, and stock fan clutch back in one of my friends car, and the other we installed a spal puller....

    Nice setup, anyone is way better off with a stock all aluminum radiator with a good puller fan than a big radiator without a fan.

    You also will pull enough air through the condensor at idle for the AC if you still have it.

    I plan on upgrading to an all aluminum radiator next year and will see if the aux fan in the stock location is good enough. If not, then SPAL fan here I come.

    Negative, They no longer sell the rads you speak of. They were by Ireland engineering and after a few issues they decided to up the ante and go with a much better design in the 400-500 range. This new radiator won't be out for another month. I'm on the waiting list.
    Also, concerning the radiators, we are our changing our radiator manufacturer and will be carrying a new all alloy unit incorporating a all alloy reservoir, bleed screw, and cap. The radiators will be available by the end of June, and the reservoirs near the end of August. Our old radiator manufacturer(the same as Ireland Engineering) has made some upgrades as of late that have cured a lot of the leak issues, but we have decided to take the quality up a notch and sell a all around better radiator in the $400-500 range.

    Thanks,
    Brian

    Guys I have a little question.

    The orange wire that goes to ignition.

    Where did you all wire it to ?

    I read about pin 16/secondary air pump, but what about OBD1 cars ?

    By the way here's a pic of my install, before putting the shroud back on.

    Szed did the brackets !

    I'd like to add something to this thread if it hasn't been mentioned already.

    There are (2) Green/White wires in the diagnostic port. You want to use the THICKER of the two. I tapped into the smaller one and it obviously didn't work.

    Damn, that looks pimp.

    But I'm not sure if I like the shrouding covering the whole backside of the radiator like that. Don't you think it would be more effective if air could move through the whole unit?


    edit- on second thought, it prob is even more effective??

    I think my fan switch is bad so the previous owner had my aux fan hooked up to a switch, that I just turn on in traffic/autox. I am replacing the clutch fan with an electric fan from a ford taurus and was wondering: if the fan switch is good why can't I just hook the aux fan straight to the low-speed-wire, and the taurus fan straight up to the high-speed-wire from the switch? a/c was removed from the car

    BUMP, is it safe to run just the spal on the high switch? My aux fan makes my car vibrate and makes noise, I rather have it off. But it needs power for the spal to come on!

    Doesn't matter, 12v is 12v. Not the same as the aux fan which has a low and high motor.

    I deleted my clutch fan a long time ago and recently had my aux die while in traffic. When I made it home I ordered a spal pusher, took the front bumper off the car, stripped all the a/c along with the worthless aux fan and cut the aux fan plug off the wiring harness. When the spal came I mounted it on the rad and soldered both positive wires from the car to the positive for the fan and neg to neg. It's been doing great for the past month, no issues.
