I'm considering a gilmer bekt type of set up and was wondering which ectric fan is up to the task of cooling a rotary? Thanks

 

I used a cheap 2000cfm ebay fan got it for under 30 bucks. I havent had any issues with it at all I daily drive my car and have put about 15000 miles on it since install. Make sure you use a thermo switch so you dont need to toggle it. My car is a gsl-se with a gilmer drive and the ebay fan was slim enough to fit between it and the rad. I have a racing beat header with no heat sheild so it gets hot under the hood and i havent had any cooling issues.

I hope this helps good luck.

 

Anything that has more than 2000 cfm will work well. A lot of folks get the taurus efans from
early nineties taurii and run them on low. Works well. I have a dual fan setup from a MR2 GEN I
(early 80s vintage) that works really well and is setup redundant, so that a single failure won't
cause both fans to fail.

I've heard bad things about the gilmer setups wearing front eshaft bearings and such
prematurely. Also they make a lot of noise. I can see using it for a blower I guess.

 

The reason gilmer drives get a bad rep is because people don't know how to install them. If you try and install it like a regular belt, you're going to have a bad time. Gilmer drives DO NOT NEED TENSION ON THE BELT. In fact, they work BEST when there is no tension and just a tiny bit of slack. The less tension you put on the belt, the quieter it will be, and the less wear it will cause on the e-shaft bearings. It also makes the belt last longer and "wobble" less.

The belt on my gilmer drive has zero deflection and also is quiet until 6k RPM. The gilmer drive also means I never have to worry about my water pump not being driven under hard acceleration. For anyone not using a/c or an air pump, I whole heartedly recommend a gilmer drive over a dual belt setup, for longevity and reliability.

 

Great thanks guys!
