Anyone removed clutch fan and replaced with electric?

Brian can you just go get a few before and after dyno runs done?

That would prove a few things. Although not the most accurate of test it would eliminate the "feel" topic.

In post 43 I summarized where I was based on the constructive input. For those interested and update follows:

From various sources, including Flex-lite tech, V8s from 500 to 600 HP are adequately cooled by a fan rated at 2,200 CFM. I chose to purchase a Flex-lite 16" straight blade fan rated at 2,500 CFM. Flex-Lite advised the fan noise won't be significantly louder, I don't care if it is, and the primary reason is that it is lower profile. The fan will fit within the existing shroud covering well over the 70% needed to maximize effectiveness. The auxiliary fan will operate as designed.

The minimum HP that will then be available is 4-5. The horsepower gain I got from Dinan exhaust was 5. The price of the exhaust was in the thousands. The price of the fan and harness was just over $200. That makes it a value. Even if the HP claims are zero, it is a value to me for the side benefits.

The reason I went with Flex-lite is twofold. The tech took the time to understand my particular application and that is the brand I have always purchased and always happen with the results. I also purchased a Spal wiring harness with a relay and an inline fuse that will allow me to activate the fan by the key, by a thermostat, through a variable fan speed controller or by an on/off switch which would be in the cabin. I did not purchase a thermostat, speed controller or on/off switch. I don't think I will need any of them but in case I do I have the wiring in place. The fan was on sale. Regular price is $179, sale price was $149. Harness was $48.

Side benefits of this change are---There will no longer be stress on the water pump bearing, there may be a mileage benefit, it was time to replace the clutch fan anyway and I would spend more for a new clutch fan and it would be less efficient.

Yesterday afternoon I placed everything about where it will be so it will look like it belongs there. I did not connect anything as yet. I found a place in the fusebox under the dash that only has power when the key is on and is not used. The hot wire will plug in the side of the socket that is hot. In my case it is the top connection. The positive wire on the fan will run to the relay, I will ground the fan 90 degrees from the fan, pulled taunt, using the same route as the positive fan wire. The wire from the relay to the fusebox will run over the top of the radiator and along the passenger side and be combined with wires I have added for other mods. All wires will be hidden by shrouds or harness covers. Any wires that are too short will be spiced with wires of the same color and gauge so that there is no load question and they will be easy to trace if need be. I will test the fan before securing putting the wiring in place.

Sorry that you find google useless. I use it all the time. And if you google you'll find more information from a variety of sources on the subject. That's how people who want to learn, learn.

As to not moving the discussion forward, it depends on what your goal is. If it's just to rip out the fan and replace it because you want to do it without any regard to questioning if it's really going to result in a noticeable performance increase, I plead guilty. If you want to approach it from the standpoint of asking the simple question of how much power are you talking about saving, before you embark, then I say I have moved it forward, because no one has any data at all that suggests that fan consumes enough HP that you're going to notice the difference in performance of the vehicle.

And the discussion has uncovered some interesting theories, like the poster who says you can feel a difference in performance, but it won't show up in performance numbers of the car. That's some very interesting science.

Another example of your fantasy world is your claim that those that want to learn use Google. I hope this doesn't depress you but there is no litmus test for internet accuracy.

You have moved nothing forward. The best you can claim is you added pages with the same song same verse obstinate junk. Congratulations!

Hey Guys,

We should just ignore Trader4 and continue on with the project. Let not waste time anymore and get to the result.

I agree if that were possible. Unfortunately, there is enough change in back to back dyno runs from all the variables that it can be and should be challenged. Anyway, I don't want to do more runs than necessary. I will already be doing more than I would like the next time out to test and tune to other far more significant changes I am making to existing engine mods and one I recently added.

The benefits of an electric fan are not a myth and there is nothing that will change a mind that blocks everything except verification of their views.

Couldn't agree more.

I should have ignored it from the beginning, oopsie. I couldn't help myself. I get irritated when someone jumps in on page seven never having read the prior pages, is off topic from the title of the thread, doesn't ask why anyone has come to the conclusions they have, is rude, doesn't have a any experience associated with the topic and regardless of the input is not able to consider anything other than their warped view.

Does anyone else hear nothing?

Looking at the face lift electric puller fans, they have a 4 wire setup vs the 3 wire aux pusher fan. Does anyone have a wiring diagram for it?
