Electric fan hookup?

Graham19922011 · Jun 6, 2019

2006 GT. I bought a ff dynamics electric fan to remove the big stock shroud to get more space for my turbo. How do these hook up? There is a red and black wire going to the connector on the stock fan now, and a red and black wire on the ff dynamics fan. Do I use a fan controller? Change out the relay/fuse and just splice the two wires? I'm new to this. Thanks in advance.

The fan and shroud are one piece, with one connector. Use the same
harness if you can.

Move the speed control resistor from stock shroud to the back of the ffd fan and then wire the ffd fan motor wires to the resistor output red and black wires. Some Male and female spade connectors work great. If it's the 3000 cfm version stock 20amp fuse is fine if it's the 3600cfm version likely need a 30amp fuse and upgrade to 10awg wires. I attached a pic of how I did mine.

Difference in stock fan w/ shroud and FF Dynamics 3000 series 16” fan. Wiring update soon.

You still going to use a shroud? There is a reason for the shroud.
If you don't use one, you will pull air in from all around the fan edge,
which will be from the engine compartment. The shroud will make
sure all the air is coming from the front.

Absolutely will need a shroud if you street drive the car.

Yep, you're gonna loose so much efficiency without a shroud. Almost guarantee overheating issues. Maybe add an electric H20 pump and it may alleviate the issue at low speeds when you don't have air flowing naturally through the radiator. That fan by itself will never pull enough air through at idle or low speeds.

A 3000 cfm fan won’t pull enough air?

It will pull a lot of air but it will not pull it through the radiator like it should without the shroud. It may work, it may not. The stock fan blows around 2000-2200 CFM. If your efficiency loss is around 30% your overall cooling capacity should stay relatively the same. BUT I can almost guarantee that at idle or slow speeds your efficiency loss is going to be much greater than 30%.

Okay that's more of what I was thinking. This will 90% of the time be a street driven car and Making a small shroud wouldn't take much time at all. I've got a water temp gauge and will be watching the temp at idle/in traffic. Thanks for your help.

Car will over heat sitting at idle for long periods and city driving and stop and go in the summer. Been there tested that my first setup had no shroud. I vented my hood, larger radiator, colder tstat just to make it manageable. Was just a pia for a street car. Hence had that shroud made awhile back.

Now your in luck you can get an aluminum thin shroud/fan on Ebay for cheap. The fan is a piece of shit and dont work, but that's easy mod to swap in your ffd fan. Thats what I would do.

Sounds like that’s what I’ll do, thanks for your help guys.
