electric fan
I was wondering how much horsepower is to be gained from removing the stock fan and installing an e-fan? I recently rebuilt my 12a and had both the fan and rats nest removed. Since then, the engine has been running hotter ( about half way on the guage... sometimes more depending on the weather and the way I am driving it ). It used to only get about a quarter way up the guage before the rebuild and removal of the stock fan. In short, I am not sure I trust the cooling ability of the e-fan and am thinking of re-installing the stock one that I saved. What do you guys/gals thik?

I have read in the past that an electric fan will increase horsepower by realistically 1 HP. Some clame anywhere from 5 to 15 HP, but you have to remember you are also making more work for the alternator. As the alternator works harder, the pull on the engine gets greater. This is just what I have read recently, so I could be wrong. If I remember where I found this info I will post a link. Sounds reasonable to me though. Just take it with a grain of salt.

An efan reduces the underhood noise, and increases the response in 1st/2nd gear. You can feel the difference. Do a search for MR2 fans, and you will find my writeup on my installation. Cheap and very effective and couldn't be any easier to install.

i used a dual e-fan from an '86 toyota mr2 and couldn't have been happier kept my 12a cool on a few +100* day's. cheap, easy to wire, and 2 screws to mount to the rad.

mine is wired to an adjustible switch that cuts it on and off for a period even after the engine is off. If it runs too long, the battery dies, so mabye i should wire it right to the battery. It should run constantly when the car is running and shut down when the car is off. I'm asking because bwlfly's looks to be wired directly to the battery. Am i right, or talking out of my ***. Thank you for your previous and future replies.

You want to draw power to the relay from an ignition source (power wire on a coil will work fine). That wire will just tell the relay that it is okay to activate once the temp is up. The actual power to the fan will run from the battery to the relay, then to the fan. Clear as mud?

no im not wired directly to the bat there wouldnt be any controll of the fan
its just hooked to the traling coil for power as a temporey while i was test drivin the car from the months of putin it together
i will wire like kentetsu said i had the main power from the realay off the fusible links screw and the igniton wire off the traling positive as sugested above
imho its the easeyest way to set the fan up

Mine is wired with it's own thermostate that can be adjusted to turn on at any temp. You just put a flat head in the dial and turn left or right to adjust It runs even when the car is off but not too long. Havn't had any problems with it yet and the old owner had it for two years without problems.
