Flex fan upgrade??

Go electric.

--BillyM

What do you mean...sorry this is one aspect of the car I never did ANY research on?

ya go electric. i got an electric fan at pick-a-part for like $15. you can get one off any FWD car. try to get one that a had V6 in it though. the fans for the 4 bangers are wimpy. you just need to modify it to fit your rad. then run zip ties thruogh the rad and thru some holes in the fan then your done. dont forget to use some plastic washes or something between the zipties and the rad though.

Last time I checked the aluminum fins on MY rad were NOT structural elements for me to mount things to. I'm not saying it won't work but come on ... it's a bit "Getto" for a Supra. Maybe I drive on worse roads than you but I would expect a good size fan to just about rip my freshly re-cored rad in half after a trip home with friends. I do agree with the electric upgrade, just take a bit of time to mount it somthing solid.

Ok so eletric is the way to go......Mounting can be worked out, but just out of curosity why not the flex fan?

good question

Easy, 4 to 5 horsepower increase when the fan isn't on plus you can control when the fan is on more accuratly AND you can rig a timer to turn the fan on for a few miniuts when you turn it off to prevent heat soak.

Actually, the electric fans that you purchase from the Zone and the like mount through the rad with zip tie like fasteners. This is what I'm running and I have two of them.

Have you ever heard one? Go find someone with one, have them rev it up to 4,000. WHAT?!!! WHAAAAT?!!! I CANT HEAR YOU OVER MY HUGE RADIATOR PROPELLER!

FAL-fans.. Has anyone played with that particular brand!? I heard they're good, but mainly from peepz with Honda's. Just wondering if anyone has done it to their Supra's...

FWIW I'm running twin MA70 electric fans (ie the medium-sized aircon fan, not the tiny ones in the fan shroud), and they're a great fit on the MA61 radiator. They're also doing a fine job keeping a 400hp 2JZ-GTE cool in the Aussie summer.

I mounted them using some very basic brackets constructed from flat steel bar, which bolt to the frame of the radiator on either side. I'm no metal fabrication genius, but I still had no problems using nothing more sophisticated than a hacksaw and a drill. I also used two strategically placed zip-ties through the radiator core to stop the fans from flapping around.

It's been like this for about 3 months now and I'm quite happy with the results. It was also very cheap, since I got the fans for free (friend was throwing them out). The only thing which really cost anything was the thermostat to switch the fans on and off.

why not flex fan?

They do not move air at higher rpm, every dirt tracker i know started off with a flex to "save hp", later went to steel non-flex fan because you can't make hp with a overheated engine.

Does this fact make it a good thing to do?

Like I said before, the roads in Canada get heaved all over the place because of the freezing and thawing of the ground under the road. I've seen a truck rad come loose and swing into the engine fan. :flex: Can you say FUBAR??? I didn't know companys would go to such an extremely cheap method of mounting just to make it a "universal" fit. It's probably fine for everyday driving. I just get a bit tired of hearing people say that just mounted a new 9" Ford rear end into thier Supar for drag racing using 100 MPH tape, structural tinfoil, and a package of zip ties ...

I'll take a look at those rad mounting ties ... maybe i'm missing somthing good? :banghead:

OEM upgrade is a late model 7MGTE fan and a fan clutch from a 92 Landcruiser.

As for electric Perma-Cool and Spal make very nice electric fans both for the radiator and for the A/C condenser. Spal makes a 10" or 11" fan that has more cfm and low amp draw. Check eBay for Spal.

You guys with the electric fans......So you just pull off the old fan(clutch and all) and mount the electric fan basket to the backside of the radiator then wire it up? I'm just going to get one from pepadvancezoneboys and recomendations for size power wiring extras?
