New Project - Pusher Fans

[FredG]

It's been some winter for projects and upgrades. Carbon fiber dash and new gauges along with LED warning lights and switches. Upgraded headlights. Aluminum gas tank. Rear shocks. Front steering upgrade. Front shocks and springs upgrade. New Carb. Now...pusher fans. Do I need them? Nope my 427R does just fine with the puller even on the hottest days. Do they look sharp? Definitely. Will be functional? Of course. I just need to decide how I want them to work. They will be independent of the puller.

Did you fabricate the mounting bar? I have a pair of fans myself, and haven't installed them yet.

Thanks for posting this Fred. Please post a shopping list and some dimensions done.

I will post updates and info as I get into it. Mounting bar came with it. Probably going to do a separate switch with a circuit breaker and relay. I want to test them with my DC power supply. Here is where I got them from.

I purchased the same set up and installed them on my SPF Cobra. The mounting brackets on the side are a joke. There is no way that you can use them. They are so flimsy that you can't weld them to the bar. You will have to fabricate something to be able to attach the bar to. Not impossible but it will be necessary. Mine is operated on a dedicated circuit with a relay controlled by its own switch on the dash board. I agree that the puller fans do a great job but the pushers are for eye candy.

I take it you are referring to those little plates that were taped on to one end. I pretty much discounted them. I will figure out something for the brackets. I am pretty pleased with the quality of the set up. I will run a 12v lead with a reset breaker off the backside off the battery cut off to a relay that will be activated by the ignition switch. From there through a toggle with a blue LED indicator to the fans. I don't want them running unless I switch them on.

Fred, I added two buss bars (1 + and 1 -) in the trunk near my battery cut off. Ran a 40 amp C/B to the positive one.

Mainly so it would be easy to add-remove items to the car. Like the EFI setup I experimented with a couple of years ago, added phone charger etc...

I had Lucas toggles for a short while for fans, fuel pump, and used metal switch labels from https://www.bits4landys.co.uk/series...s-switches.htm

As usual the Lucas switches died in short order. (I should know better)

The next set of labels I'm ordering thru Carolina Laser. 1/2 bore for standard toggles. https://www.legend-plates.com/toggle...late-two-lines $4.00 each

I never even considered a phone charger. Hi tech. Here is a picture of the unit with a ruler. It's about 1 inch too long to fit so I trimmed a half off each side. Mounting will require a little creative engineering as all of the structure around the radiator is fiberglass. You need about 2 inches of clearance from the support to the radiator for fan clearance. The motors are heavy and not balanced on the support so the want to roll. That issue is solved with 2 supports. I will figure it out.

Thanks, I'm glad its not made of Pallet racks like some I've seen, lol.

That's funny. I have seen those. The fans have some weight to them so they will have to be securely mounted.

Looks great. The one thing I have found with the pusher fans is that they lower the coolant temp when they are used in conjunction with the puller. I put them on occasionally when it's 90 plus out and the temp starts to creep above 190. Car quickly cools to 180 and lower. They look and sound really cool also. Next project will be the oil thermostat to get the oil temp up.
