If you say so. :e-shrug:

you can improve the cooling with a larger flowing fan, but the biggest gain is in the little bit of hp gain by the engine not having to spin the fan. The other added benefits are greater temp control by what temp the fan turns on and off. The stock fan works fine if you are keeping it stock, add boost or other mods may require greater cooling needs. You decide.

Adrian how much faster was your car through the quarter for having that Lektrik fan?

No clue, but since the old one was siezed, I can only assume the incredible ET's I'd be laying down without the electric one.

It makes a big difference if you want to run a thicker than stock intercooler - which is probably the first stage 1 mod I would do to a tbrick.
 
this thread does not deliver.

1. if your dad says it doesnt do anything, then dont bother posting about it
2. the efan isnt a weight thing, its a cooling thing, or a sound thing, and at the very least a reciprocal friction thing
3. my dad once told me that 17x7" wheels wouldnt fit on a 240 :e-shrug:

1. I posted before my dad mentioned that
2. I know the fan is a cooling "thing".
3. yes of course 17-7" wheels would fit. ;-)
 
by removing the stock clutch driven fan which is driven by a belt you win in a few categories. (i'm still trying to gather the exact setup that i want)

{}First there is less frictional losses seen by the motor. = more power

{}second : less inertia the motor has to change when you hit the throttle = better throttle response + power

other benefits have been mentioned. Enjoy!

Power gains are pretty minimal unless your existing clutch is fried, as Mr. Lane alluded to.
 
PRO:
Just switching from a V belt to serpentine creates a measurable difference.
Removing a belt driven acessory again creates a measurable difference.
Less inertial resistance to acelleration is good
Max fan flow at idle is nice
You can wire it to cut out at full throttle, reducing load when you need power most.
In drag racing, 1/100's of a secongd count, amd may be the difference between a win and a loose.

CON
Control circutry can fail.
Range after alternator failure will be reduced.
It doesn't make the cool noise a flex fan does

NOTE
almost every car on the market today has both an e fan and serpentine belts.
 
So, on the topic of lektric fans...what are good donor cars to grab one off of to fit to a 745ti with a B230ft? I never know what cars to look for to get a fan from, so the idea usually fades away...I really just need to know what car to grab it from and the project will happen, im sure of it :)

I think it would be quite easy to get one on there, if you got one that almost fit anyway at least...what do you think?
 
The major concern with electric fans is that they could stop working without you knowing and your motor could overheat.

But the advantages are the power that it frees up and also, your car won't have the work truck sound to it anymore.

That permacool is loud enough that I'll know if it ever stops. Plus my car will idle nicely again. :-P
 
24mpg in all city driving with automatic transmission. It does something.

main benefits are:
improved fuel economy especially in stop and go driving.
much quieter engine
extra room to work around the engine.

disadvantages:
you absolutely must have an uncompensated working temp gauge and extra fuses in the glove box. The first fuse went at after 15 moths and about 12k miles. I caught it as I was just getting on the freeway as the temp gauge went past the half way point. As soon as we were on the freeway temp went back down below half way. Replaced the fuse at the next stop and all was well. People blow this problem way out of proportion.
