I have spal mounted to stock shroud. Super easy with the spal bracket. Have had zero issues with cooling. I'm in Phoenix where summer temps are currently 110+.

What else did you buy besides the spal fan?

Mine came with 4 mounting brackets that I was going to use to mount to the stock shroud - then just use the aux fan controller and hook it up to the Spal fan. I'm hoping it's that easy...

ECS has a good price. But I found on ebay - brand new in the box from a dealer - for 30 bucks less.


I will back what he is saying. I also have a mish fan kit and like above it is a great setup. No issues, wires in easy enough and looks good.

Bump.. looking for current consensus on best fan solution for our cars. The mish one is tempting because the kit includes everything you need... Reviewing a lot of older threads like this one there doesn't seem to be consensus on what is best? Is factory solution best?

Aside from preventative maintenance is the performance gain really worthwhile? Anyone have good data points?

Thanks

Default Re: Electric fan upgrade

I did it because the mechanical fan broke a blade and took out my radiator. I hated that.. I mounted it to my stock shroud and did my own wiring. Easy. I noticed instantly the car drives different. Has more torque from a stand still in low rpms. When the mechanical fan locks it definately robs u from some power. That never happens with an electric fan. As far as data, I had a before and after dyno. No difference that I could detect in peak power. The mechanical fan disengages at 4.5k rpm or so, but the car drives different around town and picks up much better, but you wouldn't see it on a dyno, unless ur clutch fan was locked and that usually doesn't happen on a dyno with the car cool and fans blowing air in front of it.
Motor trend did an episode on fans of all sorts and viscous clutch fan robbed the engine from significant power. But my dyno sessions didn't show a difference.
In conclusion, I wouldn't go back to a mechanical fan unless I'm Turbo or supercharged, as the mechanical fan does cool better

I went with the 330i 400 watt electric fan option and got rid of both the aux fan and fan clutch. Iím supercharged and this is a factory part (which Iím a big fan of). I run just under half on the gauge at all times. Itís amazing...

Running a Mishimoto with the clutch fan, aux fan, and AC deleted. I like that it’s simpler and lighter than the factory setup, plus it’s a lot easier to do maintenance without the fan and shroud in the way. I went with the Mishimoto over the alternatives because it’s basically plug and play.

I didn’t have any cooling issues before, so I can’t say whether it helps in that regard. The fan rarely comes during normal driving, and even on track the temp gauge stays below half all the time.

I haven’t noticed any increase in performance.

I have a Mishimoto fan in my car. It was pretty easy to install and does the job. Can’t complain.

I got the mounting bracket from mishimoto, will use a different fan tho (something that has stronger cfm, mishimoto has 1650cfm if I remember it right)
