Flex Fans

Does anyone here have any experience or opinions about flex fans? Do they help the engines performce (reduce drag enough to make a difference) at higher RMP?

Well I didn't really notice anything when i installed mine. I ahve the flex-a-lite (FAL) dual slimline settup on my 84'. Makes the engine bay look much better, sounds better (don't hear the fans whoosh when revving anymore) and IMO perform much better. Car runs very cool in 110+ AZ heat :lol:
How well does that dual slimline fit our core? Any pictures?
do we need an adapeter (they sell them on their site) for the mkii's? what part # or size did you use... if you remember... thanks!!
Generally speaking you use flex fans on cars with no fan clutch (i.e. some muscle cars). About the only thing you might gain from the flex fan is a little less rotating mass. The factory fluid clutch basically does what the flex fan does (and probably does it better). I would go with an electric setup if you want to upgrade this area.
Yes it fits the radiator SOOOO good. Its got a nice flexible rubber sealer around it that keeps it attached so no air really escapes. Its a great upagrade IMO, as Ilike to ahve adjustability over the fans at all times cause sometimes it just gets to hot here in AZ. I will be getting a camera in this weekend Ill snap some pics of the beaty and put em up real soon...

Dyno runs comparing clutch fan to e-fan. The scale changes between the two, and all runs were made in 3rd rather than 4th, but it's usefull for the sake of comparison.

Heres then just laying on the radiator, as you can see they fit great! Completely adjustable thermo switch included :twisted:

you have yours lying on the front of the rad, did you wire yours up to be a pusher fan instead of a sucker? They actually fit just fine on the other side, but you have to trim about a 1/4 of an inch off either end to make it fit into our rad as the ends on our rads protrude a little. I imagine you;d have to remove your ac condensor to get the fan onto the front end of the rad. BTW, toyman was asking about flex fans, not the same thing as electric fans. I have the 210 flex a lite as well, awesome fan and I swear it feels like it makes way more power then the dyno shows above, but those are impressive numbers either way. Lately my brand new clutch fan has been locking up alot in the hot weather, can't wait to put my electric in.
where did you get those dual electric fans that fit soo nicely, i tried on my 84 to put a single fan on and it did a good job cooling but it looked quite stupid...and i had one that mounted through the radiator fins...wasn't pretty........part number, price, location??????
Actually the pic is just a layout of them, Im currently doing tons of work to the car right now and they were out so I thought Id just show a pic of how they look. THey are suckers and normally mounts on the back like normal. They are the same as suprafiends....

Flex-a-lite 210 sucker fans with thermostatic sontrol and a/c relay.
The 110 and 120 models are single and obvioulsy the 210 and 220 are duals. The 20 series of each doesnt ahve the thermostat and a/c control but are a bit cheaper cause of it. I got these off of ebay actually. I have another set on my Talon that i bought from a local distributor of FAL. Just do some searching to where the cheapest place is. I got these for $160 from ebay and the new ones for my Talon for $225.... :twisted:
those are good prices if you can get them new for that.

Ok then, just to clear it up for others, if you mount the 210 flexalite on the back side of the rad, which is easiest and most effiecent, you need to trim a 1/4 of an inch of each end of the fan to make it fit. This involves triming the seal there too but it still seals well.

Most performance parts shops sell flex alite fans
moorman... is it just me, or did your torque take a huge jump with the electric fans?

im usually pretty decent at reading a dyno sheet, but im not sure if that huge jump is correct, or if my eyes decieve me, and also, whats the speed that most cars torque and horsepower lines converge? isnt it usually around 5252 rpm??

Were the fans running when you dynoed with EF? In real life, when
the cars moving, the EF's would probably be off (especially in the
upper gears). If the fans draw about 20 Amps you're using about
1/2 HP to run them (including inefficiency losses) so you should add
1/2 HP to your EF dyno run.

Take a closer look at the graphs, I was thrown off at first as well. The scale numbers are different on the 2 charts. In both cases, his peak torque was just over 135.
