Electric cooling fan question !

[NERDE30]

Would a 16in pusher electric fan blowing 1500 CFM's be enough to keep my S50 swapped E30 running cool ?

[sharky]

yes

[328ijunkie]

1500 is a little low.... Stock fan pushes more.

[NERDE30]

Damn so what should I be looking for as in CFM range

[sharky]

you will be fine, ran a 1600 w/ S52 supercharged and never had a issue, low temp thermo, mishimoto rad, BMW coolant 50/50 w/ watter wetter

[NERDE30]

OK cause what I have as of now is M42 rad, slim fan 16in , new thermo , I am gonna have to grab some of that spiffy BMW coolant

That's what you should be using on the 24V motors, anyway.

I have a 16" SPAL puller on my M42 radiator, and it does the job just fine! Just make sure you fab up some actual brackets for mounting it, don't use those little zip-tie things that come with it, you will ruin your radiator.

Will Massive brackets ^ work on stk 89 radiator for 'puller' fan /? thanks

[Den_k321]

any links where to buy those 1600 or 1500? thanks.

Here's my brackets:

Simple, and probably cheaper to make than Massive's overpriced stuff.

[samiam3356]

Wouldn't take too much ingenuity to come up with something.many have got by with the plastic zip ties.I don't like them but a few drifting buddies have used them without issue.

[Jand3rson]

Those plastic zip ties are serrated, eventually, they will vibrate and cut through the fins of the radiator.

I had a similar set up and it worked good on the hottest of days(seattle).......however on the track when the engine would see high rpm's for a long time it would get way to hot. The fix for me was the thicker IE radiator
