I was wondering awhile ago what the cfm of the stock fan is.

the OEM its only a single speed, 3 blades ?

This twin is very efficent and  it covers the complete radiator and is multi speed

the thin will help with the intercooler , as I can move the radiator closer/ rearward...

I suspect someone good with math can measure the surface area of the stock fan and knowing it's RPM, calculate it's CFM.
I've thought about replacing it a number of times just for the sake of making less clutter and more room in the engine bay,
but units I thought via guessing would be sufficient were cost prohibitive for fixing something that isn't broken in a stock
application.  Interested to hear how it performs.

$400.00. That is what will keep me from getting that. Also they posted 2,500 cfm on the Flex-A-Lite website.

Yeah, the cost to match or better the stock fan's, assumed, output is pretty high.
And they last forever even if they are huge and bulky.  Still cool though.

I'm not sure how these compare to VW fans but this was an issue people ran into in the Jeep community I was a part of, that aftermarket electric fans often did not exceed, or even match, the airflow of OEM electric fans or even the mechanical fan. This is something I would have to know before buying.

Iam sure you have seen a three blade mk1 fan correct ?

If you take a kesterl wind gauge you would understand the different flow between the two assys

This model covers the complete radiator ( shrouud ) the stock is just a partial

nite and day difference

Most people wont do this mod as the cost is a little high, Iam reducing three inches of room to my install..

I love the idea of reducing the depth takes to mount it on the radiator. You could move the radiator back and run A/C condenser up front. If you wanted

100% correct

Same hoses, just trim to length, moving the battery really gives room so both in and out tubes from the intercooler are on the drivers side..

I started out with the 3 blade single speed fan on a truck that came with A/C (factory adder sans AC parts). This motor didn't have a 'high speed' option which engages with the compressor.

The factory replacement 6 blade cooling fan cost <$20 and a new replacement 2 speed motor cost <$30 from Rock Auto...

I had already replaced the radiator, hoses, with a 180 thermostat before adding the 6 blade/2 spd assy.

When wiring it in, I simply wired it to run off the "high" speed terminals anytime the thermal switch was made at ~210 degrees F. Of note - you CAN wire these motors to run backwards if you're not paying attention. They're not shaded pole or...so they will run in bot directions.

Under normal driving, the engine runs right on the thermostat at 180 degrees; same with highway cruising at 70-75mph.

When the temperature does trip the thermal switch, it returns to 180 degrees in about 1 minute; about 2 minutes if it runs on 'low' fan speed setting.

I'd have to agree with others relative to cost here; it wouldn't be worth an additional $300 to gain seconds on my cooling cycle. If your setup it tight (no leaks) and in good condition, it's gonna be tough to beat the factory stuff when everything's working properly.

Its about going to 2.25 depth if adding a intercooler in front of the a/c condenser.

With this fan you can move the 26 ' wide scirocco radiator or the stock 22 all the way back to the end of the core support .

I got a freebie and I will be making the a/c version Callaway intercooler kits and his wont relly be needed, but I still like this as it covers the 26 ' wide core of the radiator ..

The intercooler is avaiable from Bell Intercooler

I pickedup another complete AHU with ctn trans over the weekend for 750.00 and a very nice 1981 MK1 Jetta coupe to install it in after complete
paint.

Another AHU build to keep my hands busy with my son.

My 92 Eco has dual fans each with 12 blades, driven by a belt via an electric motor with 2 speeds, controlled by the rad temp switch. I have zero problems with it keeping the temperatures in check. I can't see an aftermarket setup being any better cooling wise than the OE other than maybe thinner and take up less room.

Ah, but that extra room is so nice when digging around under the hood, not to mention aesthetics  8)
I think I spent $50 on two 'chinese special' ebay fans; they keep my temp guage centered perfectly, and I love the extra room. If (when ::)) they crap out I'll just throw the old unit back in for a quick fix, and hopefully have money to get a better quality pair of fans. After going slim profile, I can't see going back to the stock unit as a permanent thing.

I never complain when I get freebies from Flex a Lite

The last install on my SC 5.7 Tundra went well, no noise when startup, fan shuts off on the freeway when a/c is..

They see my stuff at Sema every year and we always exhanging idea's to get thing running cool and increasing flow

I've run the 365 on several cars. I really liked the way it cleaned up the bay. 1600cfm and never an issue.
