Finally getting around to installing an electric fan I got from Summit (replacing the clutch fan). Can I get some advice on the best mounting and wiring routes?

I'm down to just using the plastic tabs (carefully) but the AC condensor is too close to use them. Can I move the condensor without disconnecting the tube on the left side? Is there another easy way to mount it without using the plastic tabs?

I was planning on splicing the wires in with the aux fan or installing a on/off switch in the cockpit.

I'm getting ready for my road trip in 10 days so I definately want the extra cooling.

You can just simply buy a Thermo switch kit from any of the local auto part stores for under $30. I bought mine for $30CDN and the kit contained everything including a dual fan activation relay. It’s a lot easier and safer than installing a switch in the cockpit. You don’t have to remember turning it on and off, it will do it automatically. Also, the installation time would be a lot less than running wires from the engine to the cockpit.

I hope this helps.

Thanks Imre, that's what I'm leaning towards

I bought a fan from ebay and I removed my old electric one along with the belt fan. I just plugged the new one into the old electric one's connection. Will that work?

I have a few choices for the wiring, just a little hesitant when it come to mounting I really don't want to use the palstic tabs and not quite sure about the easiest bracket method.

There has to be more than a few rennlisters that have installed after market electric fans on pre 87 .

I just need some pointers on where to secure mount brackets so I don't have to use the plastic tabs. Pic's would be nice

I made 5 or 6 little pieces of metal which are attached to the plastic shroud (with backing plates), which then bolt to the fan mount points, and the fan is centered as best as possible in the shroud space. Like flat extension pieces.

I have been racing with this setup for 3 years in the blue 928 without any problems - no issues with the shroud cracking or breaking, and certainly no cooling issues. In fact, with the fan away from the rad has showed far superior cooling than with the fan close to the rad.

I've seen that before, very professional a bit out of my league when it comes to fabricating sheet metal. Plus that's a replacement for the aux fan, I'm keeping mine and replacing the clutch fan. I think 2 are better than one here in Las Vegas 100+ deg weather.

Thanks...

Forget the plastic pins and take some extra time and fab an aluminum bracket and bolt it to the radiator.

I vote bracket too.... I know Devek offers a fan shroud to put two fans behind the radiator... you might check and see if they offer a single.

Darien,

You're in Vegas right? I suggest that you head over to Dr. Harkin's house of fabrication. I heard that dude can fab a Super Charger out of Bubblegum and ball bearings!!!

Give Tony a call. Second thought, he may be busy doing burnouts at the track!

Ha Ha

Chuck, I've come to rely on Tony on a few matters (i.e., t-belt/wp), great dude We were just in there contemplating using the plastic tabs...

I think I'll just make some straight brackets and use the existing fan shroud mount holes.

Good luck with it, post pics when you complete.

Using a fan shroud greatly increases the amount of air moved thru the radiator. You do NOT want the fan completely buried in the shroud, but instead want the fan blades to be about 3/4 of the way out of the shroud. This allows the fan to act as a combination axial and centrifugal blower, which is much more effective.
