A constant 40mph requires very little engine power. Very little engine power requires very little cooling. If you need a fan running to do that speed then something is wrong with your cooling system.

I have to be going above 40 depending on the outside air temps to keep the engine cool without the fan with no belly pan.

What do you expect if you have no fan or undertray? Removing the undertray significantly reduces aiflow through the radiator, we all know that. I'm not sure what that's supposed to prove.

Your missing the point. The e-fan, when on, would require less hp then a clutch fan no matter what temp the engine is at when at higher rpms which is where the stock clutch fan has a greater possibility of consuming more hp. Eventually the clutch would disengauge even more but not right away.

Who cares? The amount of power you're talking about is so small it just doesn't matter. Maybe I'm reading too much into it, or maybe you're not being quite clear enough, but with all this talk of power loesses you sound like you're claiming a worthwhile measurable improvement in the car's performance from fitting an e-fan. I don't believe that to be the case and have seen no evidence of it. This is why all these e-fan discussions annoy me. People seem intent on blowing the so-called advantages of e-fans all out of proportion.

How so? Im not going to repost anything Steve or I have already said in the articles we made. Its time to start reading.

I want to see the measured change in the car's performance, i.e. back-to-back acceleration testing that proves an e-fan makes the car consistently faster. Power and airflow calculations don't even come close to proving that.

Depending on the temps I would have to go above 40. If the outside temps are around say 70-80*F then yes 40 is fine. Higher then that I would need to be going a little faster..

Im actually GLAD you think the same. There has been a few saying even on the highway you would overheat without a fan.

No kidding, which is why I also added, A/C heat exchanger and FMIC.

Yes it is very small, I was simply trying to point out where the benefits of the E-fan are and where the benefits of the clutch fan are.

I noticed my last post was more of an argument instead of what I intended it to be and I appologize for that. Simply put, im only trying to show the ones that care, both sides of this so called "mod" people say it is when it actually is not and is more or a sideways step.

I put a efan from a supercharged t-bird, it had two speeds, the higher speed would drain the battery after repeatedly turning it on and off but, the lower speed worked perfectly. i had it rigged to turn on whenever the ignition was on, ran the negitive to the battery and the positive to a green relay box. The setup was god awful in quality i'll admit, but it was effective. After i switched i did notice that the engine responded better, just a little bit though. heres pics of the one I had.

Could you measure the running amps of the low and high setting and possibly put that information in the fan list located here?

RotaMan, any updates on the airflow meter? That sounds like an interesting next step

I hope to get the meter soon but it may take a month or so to get my self straigtend out money wise. I really look forward for some very close to actual numbers. When I do measure with the meter, I don't want to call the numbers I get "Actual" numbers, instead call them "Close to actual, CTA".
