Electric Fan Conversion - Spal's 30102803HO most powerful sealed fan

[WOLFN8TR]

Bump on an old thread. Is this fan anymore powerful than the 2082 SPAL fan? https://www.summitracing.com/parts/spu-ix-30102113?cm_mmc=ppc-google-_-search-_-brands-_-keyword&gclid=EAIaIQobChMI76rP18eujgMVSV1HAR1cMz0C EAAYAiAAEgJr7PD_BwE

That fan does have more CFM's than the 2082 but the motor isn't sealed. Also 26 amps vs 24 amps with the 2082.
"Recommended for racing only.

WOLFN8TR Hows the setup running after all this time? Driving the M3 in the peak summer temps?

Still running great! Very impressed with the Spal 2082 and the Auto Cool Guy PWM combo. I daily drove my M3 for 5 years to work and the summers out here in Vegas get up to120 degrees. There were only two times when I was sitting in traffic on a 122 degree day I turned off the AC as the temps were climbing just to safe. And my SMG is still working good as well even in the high heat.




Here's some good Spal fan info: https://www.a1electric.com/catalog/cat_spal.htm

Spal 2021, 2049, 2082.

At static pressure mmH2O = CFM (which is what you look for in a fan because the total output is always at measured at 0 which is not really relevant in this case because this being installed in car radiator is pretty much always subjected to static pressure unless you have the car parked and not moving at all.

The higher mmH20 and CFM the better.

Spal Fans:

20 mmH2O
2049: 389 cfm at 20.6 amps
2021: 702 cfm at 19.5 amps
2082: 991 cfm at 24 amps

25 mmH20
2049: 0 cfm’s at 17.7 amps
2021: 378 cfm’s at 19.5 amps
2082: 596 cfm’s at 23.6 amps

30 mmH2O
2049: 0 cfm’s at 16.5 amps
2021: 0 cfm’s at 19.2 amps
2082: 384 cfm’s at 23.8 amps

Interesting i have your same setup, at 122F those oil temps are pretty low, have you made any mods to the oil cooling system?

Maybe you are running the fan controller on different settings?

Nope all stock.

[Projecte46m3]

The cooling setup that I have that makes life easy, simple, and clean...

Koyo Radiator
SPAL Electric Fan 30102082 (w/oem pusher fan)
N15 Mount Kit
Mishimoto Adjustable Fan Controller w/ 1/8" NPT Radiator Probe (plug & play into Koyo rad)
12V 30A Circuit
Moroso Coolant Expansion Tank
RE Expansion Tank Hose

[0-60motorsports]

I really need me to get a KOYO Rad! Wish FCP sold it.

This is my setup as well only difference is I'm using the Auto Cool Guy fan control and no Moroso expansion tank.

hey. i'm in the process of doing a cooling refresh. did a 3 day track weekend here in NJ (NJMP) and temps were @ 100 and coolant stayed @ 210. had to do cool down every 3-4 laps cuz it wouldn't keep up.

regardless, i see your auto cool fan controller and i ilke it but curious, any reason why the derale PWM controller wouldn't be just as good. it has a flush mount temp probe thats PnP. not saying one is better than the other. just honestly uninformed so looking to see what i'm not seeing. or did you go w temp probe for something more accurate? thanks.

[332]

Here is my take, I believe this is the best solution. Better than the N15 design, which I ultimately threw away. I used a Technica Cooling pipe, with a thermoswitch. I then wired it through the oem loom, back to the ecu compartment where I mounted the relay. The mounts are from a not so well known company. Called Massivebrakes.com, they make top tier stuff. Enjoy!

[bigjae46]

I'd make sure the switch is grounded. That pipe won't have a good ground since there are rubber o-rings which electrically isolate the pipe. Stupid ass VAC makes a pipe like that and didn't know that when I called them about an intermittent coolant temp reading.

I'm not sure what you are talking about? This sensor reads the temp and that goes to the relay, which controls the fan. I've had zero issues with it, its lighter than almost every other setup. I was able to depin and delete all the oe wiring. idk?

educate me here. how are the massivebrakes brackets better than the n15 brackets? i mean it's cheaper so that's a good thing but is it more just an alternative solution or did you see a flaw? thanks for the help.

i'm leaning towards a setup similar to what someone above (Projecte46m3) already did.
- koyo radiator
- mishimoto fan controller
- keep aux fan
- n15 or massivebrakes brackets.

If it is a two wire sender then no issue. Some senders are 1 wire which you would need to ground the sensor to the engine. I used a crimp ring as a washer on the sender, ran a small wire to the t-stat housing bolt and grounded the wire there.

Are you saying, before you grounded the sensor. You were experiencing a situation where the fan wasn't kicking on at the correct temp?

[George Hill]

He's saying that one wire sensors use the sensor body as ground and when that is screwed into something like the coolant tube (as yours is) the o-rings will sometimes provide enough insulation that the electrical ground will not be complete. This could result in the sensor working inconsistently or not at all. If that is the case I adding a wire from the sensor body to ground usually solves that, but using a 2 wire sensor with a dedicated ground wire will also work.
