O boy, I feel some bashing coming on.

[jetjock]

As Jay pointed out the consensus thus far appears overwhelming. I know in 22 years of driving my car never overheated with stock parts. Not once. You may need to refill the clutch though. It's probably dry. Or just replace it. And the fan wouldn't be hideous if you got rid of that glass hood...

 

[airhead04]

A few hp?.........Don't be an airhead.........:icon_bigg

Leave it. Spend your time, money and efforts somewhere that might actually gain you some real horsepower.

LMAO, that was good.

Ill leave it alone.

This is very good advice.

I quite enjoy my glass hood thank you.

Im the only one that ever looks at it, so its just ugly to me. I have no idea why though.

Functionality, reliability, and good design has a beauty all its own

 

[giterboosted]

When you say it sounds like a semi, I'd say it sounds like you need a new one, my turbo car sounded like it was supercharged for God knows how long til I replaced it, there's lots of partout cars in the for sale section that have maybe a better one than yours for not very much, try that out.....

 

[staticpage]

you can set up an Efan that will work just fine. It may not move more air but it will work just fine. I have one, never overheated with AC, a big FMIC, on hot days it does fine. And will argue that for some people the Efan works way better.
I feel that my clutch never fully locked it just cooled when it needed to. Or let me put it this way, a clutch only cools when it gets hot.
With an Efan when I’m sitting in traffic I can flip a switch, the Efan comes on and cools my heat soaked FMIC. And when I’m at the track the car can be off and cooling for the next go. It looks way better sounds way better (it comes on for 10secs then is off for 5mins-+ a few). If you’re looking for an visual upgrade then you can make an efan work. I have a post about mine search for it. I will not be going back to a clutch any time soon.

For some reason i feel the myth of removing the clutch fan for e-fans falls in the same category of not running a shroud or undercover.

I feel if your car overheats without these items it has other underlying issues at hand. The stock radiator should be able to easily keep engine temps down with electric fans/clutch fan, even on a hot day.

Ive run my car, stock fan no shroud or undercover and never had an issue even on 90F+ days. i got my car with neither of these items and i have never had an issue running that way.

Im not saying electric fans are better or worse, or that these items weren't installed for a reason. BUT i feel that a properly set up electric fan shouldn't be incapable of keeping the engine from overheating.

If electric fans were that unreliable manufacturers wouldn't have made the switch in new cars.

I call :bsflag:

Run an AIT sensor each side of the IC and flip your switch and report back just how well it reduced the heatsoak.....

------------
A correctly set up pair of e-fans draw a massive amount of current on startup, stop start traffic when they're needed the most your alternator is producing a fraction of what's needed, eventually your battery sags and the car runs worse and worse, I use a 140a alt and it barely keeps up.

EVERYTHING has to be done properly and yes e-fans can work but it's not cheap and don't believe the free HP bullshit, the power to turn the alternator comes from somewhere.

 

[turbo toyz]

i love my Efans.. looks good and works great.

I agree with electric fans. you will free up about 3-5 horsepower thru the entire rpm range , the horsepower will hardly be noticable. Having those hideous fanblades hanging off the front of your engine is reason enough , slim lines look so nice and even nicer if you have room to hide them on the opposite side of the condensor. You will run into overheating issues if you buy cheap ass chinese electric fans off ebay , make sure to get something with a namebrand on it, that way you can be sure of the cfm flow rating.

And to the person who said alot of engineering went into the clutch fan , My response to that is they had alot of engineering going into how much they should torque headbolts.

notice the post count of the people that x-nayed your idea (add me to that count) and now compare that to the other folks saying go for it. DO what you want, most of us have reverted back to the OEM fan setup as IJ so kindly stated, you need to address the electrical system as good flowing fans WILL pull lots of current. Freeing up power, no such thing, you are just changing where the energy conversion happens, and in the case of fans, you are introducing another conversion (and it's losses) into the picture, ie Mechanical > Electrical > back to mechanical.

Ogre

lots actually. How come I never had a BHG? oh that is right, I actually knew better than to just twist a knob to up the boost, remove egr and all those other idiocies that get spread. There torque value was fine for OEM. increase the power from stock and then it became a liability.

So care to grab one more straw?

 

[Poodles]

If it's "ugly" you're probably not running a shroud. Also, most aftermarket electric fans are absolute crap and won't flow the air needed.

 

[BOOSTEDSUPRA]

not sure if you made your decision yet, here is my experience..

my set up now is... fluidyne rad with dual flex a lite fans, controlled by a dakota digital dual fan controller.

my temp run no higher than just under 1/2 no matter what temp it is outside, no matter how hard i push the car, no matter how long it sits there and idle's.

BUT, b4 i put the aluminum rad in, the twin fans were not good enough to cool it with the lame ass controller they are sold with, poo is right in this that they would be crap. then i switched to the dakota dig. still, under harsh condition, heat, high boost, ect, got warm.

if you wanna upgrade your cooling set up, bend aaaalllll the way over and swap it all. you will not regret it.

also, my top end power gains are noticable. and hvyman has seen my set up and may have pics that i cant post on here. he might be able to explain my set up a lil better, idk.

hth


edit.. i made my own custom mount for the fans instead of using the stupid ties. i can make you one if ya decide to go this way. when you get it, like it, then just pay me shipping. no worries.

one more edit lol. about the ugly thing, its not that bad to say hideous. take it off, clean it, and cover it with a new shroud. all still avail from toyo.

Sigh. Another chump who thinks he knows more than the world's largest automaker. You know, this constant pulling out of the head bolt card gets old. Almost as old as an experienced engineer having to butt heads with dimwits on a forum made up mostly of kids and hack artists who barely qualify as backyard mechanics.

Toyota got to where it is today based almost solely on quality. Do they make mistakes? Sure. Have they otherwise produced many trouble free designs and millions upon millions of good cars? Yes. Do they know more than you about correctly engineering even the tiniest thing? Your post history answers that question better than I ever could...

ding! i agree, the head bolt thing is old.

 

[supra90turbo]

Valid points on the clutch fan side of the argument, not so much on the electric fan side.

I'll say it, I had a working clutch fan on my black supra, took it off in favor of some FAL 220's, hated them. They didn't work as good as I felt they should have, don't know for sure as I was only going off the stock coolant temp gauge, should have had an aftermarket one, but that's in the past. I sold them, and I don't regret it.

I was going to go electric fan on my new Supra, then realized that the clutch fan works, I have an intact shroud, and it WORKS. Also, it's free... think I'll leave it.

As Figgie said, look who's against the electric fans. There's a reason for this.

Good to know. I figured that's what it was but I didn't want to just throw money at it. Now I can have a 'normal' sounding engine bay again.

I played with fire when I was a kid.
I never burned myself.
Having kids play with fire is a good idea.

I smoke cigarettes.
I didnt get cancer.
Smoking cigarettes is a good idea.

I converted to efans.
My car didn't overheat.
Switching to efans is a good idea.

Do you see the fail?

Lol, I do, I do.

Im just going to leave it alone. It has been working fine and I do have a shroud.

Now 2 more questions. Im looking at building an engine that produces 500 rwhp, give or take a little. Will the mechanical fan still be okay for that? And Im looking at an aluminum radiator, will it fit still?
