fan idea

[johnny5]

ok so i noticed on my 91 de theres an electric fan and a mechanical fan. now im thinkin im just gunna hook the electric fan up to a 12v source and a switch and just get rid of the mech fan. my thinking is that ill gain a couple hp like i did in my 76 camaro when i switched over to an electric fan. ideas? comments? opinions?

you really wont gain any real HP by removing the mech fan. your take off will be a bit quicker but not huge gain.

That little e fan won't keep your motor cool. You will overheat if you do not put a bigger fan on it. That little fan just keeps your a/c condenser cool when you are at an idle so your a/c blows a/c cold instead of normal ambient air cold.

yea, prob wouldnt work out too well. but if u want to go electrical, there are plenty of stock electric fans to be had at a junk yard, just do some search on which ones u should look for

dude..you will see HP gains and a quiker throttle responce time...but..you will want a duel fan set up on an aluminum radiator..fans can be had at a pepboys for 50 bucks a pop..they work fine with toggle switches...use 1 when your normal driving..and 2 when you get her really hot..good luck

My clutch fan went out so i pulled the stock E-fan off my Talon Tsi(project car) and mounted it on. Im still waiting on getting a relay and thermo sensor, but for now i have it wired in so when my defrost fan setting is in use the fan kicks in.

i have my twin settup wired for just a fan 1 fan 2 switch..makes it easy..no other devices needed.

I took my mechanical fan off and have had no cooling problems, even with the AC (but I dont use the AC that much). I say do it

[krazy88]

Do you still have to switch it on manually?

[1KleenS13]

Nope the computer still controls it. It will run without the AC on

ok well i took the fan off and just added a switch to the elec fan so i can turn it on when the cars one, but i tihnk the p/o of this car took the thermostat out cuz the car doesnt really heat up from what i noticed, idk ill beable to tell you a lot more when i get it insured and i can take i on a drive, for now its just up and down a 1/8 mile of dead end street next to my house. and i cant get on it since theres little kids i have to behave

[liquid_cool]

you are going to want to get actual fans man..dont use that chepo fan for the AC...and get 2 fans...if you overheat and dont pay attention..its bye bye headgasket and bye bye money...take my advice...toggle it with 2 switches and 2 fans.

i will eventually as the rad has to get replaced soon its got some cracks that wer jb welded, it doesnt leak but i dont like it so im gunna buy them all at the same time

[dc1984]

i agree, thats not exactly something u would want to skimp out on. even of some people say theres has been fine without a fan, it only takes once and that could be it.and before u replace the radiator, do u plan on doing a motor swap? cause it would be kinda pointless to buy a new KA radiator if u plan on doing an sr swap in the future. but if u plan on goin NA or ka-t u would be fine. not trying to insult ur inteligence or anything, just throwing that out there.

i used the a/c fan as my fan it doesnt over heat at all unless you are doing burnouts and doughnuts but for everyday driving it will be alright. but later on i recommend getting electric fans. right now i'm about to get my two electric fans in the mail.
