It is a great fan! Pulls that air like a son of a bitch. You may want to upgrade to a S5 or better alternator though. Highly recomended.
I've got a S5, but with my aftermarket stereo that poor thing is like Roseanne Barr trying to run a marathon. With lights, heater, and stereo on at times it will be barely above 12 on my factory gauge. After I get some fuel system upgrades completed I was going to do an FD alternator. After I had the alternator do an electric fan.
Completely off topic and I don't want to jack the thread, but I see you're using an LC-1. Mind tossing me a PM or checking out my thread, simply letting me know what you think of your LC-1?
All 88-95 3.8 fans are the same so I am willing the bet it is that one. Could, when you have time you post a front shot of the fan please just to make sure. Thanks
That's the one, it's a 3 wire(i.e. 2-speed) and better shaped shroud than the single speed 3.0 liter tarus/escort etc. The high speed is an amp hog but the advantage is the option to control it on the low setting and if needed switched to the high setting. You are going to need a FD or comparable 100 amp alternator if you plan on using it on the high speed with other accessories at idle.
the 2 speed fan pulls almost 80 amps on startup on the high speed... so make sure you have a good relay that can handle it or set you fan to turn on low first

Your bay looked so good,,,,,, to bad you had to go put a 20B in it! ;0)
Stumbled across this thread. Last post was 2008 so 10 years have passed now. I'm currently running a Koyo N Flow with the stock clutch fan and shroud. I'm looking to clean up the engine bay with a Flexalite fan especially since my stock clutch fan is now 27years old. I reached out to Flexalite regarding the size. They recommended the Black Magic S-Blade (15in) since it will fit within the dimensions of the Koyo N Flow (see attached). Previously people had mentioned that they had bad experiences with failure. Is that still the general consensus?
Another option I was considering is the Direct Fit Black Magic X-Treme for a Tacoma since it's off by .5inches height. It would require a little cutting of the shroud due to the filer neck and the intake/return pipes of the system.

The 15 inch one will cover at least 80% of the radiator core. I've been using one since mid 90's. I've ran this configuration with and without a thermostat, in places close to the equator, in traffic, with AC, not issues whatsoever. The other one posted (extreme) has a larger shroud, and will require trimming it in order to clear the the radiator inlet hose (has been posted here). I currently have a 86-88 radiator rails with welded tabs for a the 15inch radiator, I can sell them to you cheap; and will make everything a bolt on affair (provided that you are running a 86-88 radiator)
Old pic of the fan mounted back in the days when I was mocking up intercooler pipes:

Thanks for the offer. But unfortunately I'm using a Series 5 N-Flow Koyo. By any chance do you have a link to where someone used a Flexalite Xtreme with the Koyo radiator?

Any decent 16" fan will give you enough coverage on that radiator even without a square shroud. I'm running a Spal (not the extreme 3000cfm one, too many amps!) mounted direct to pretty much the same radiator. It is more than adequate on the hottest days stuck in traffic.

Two things, if I may...
- Using those direct mount zip tie kinda things is a really bad idea. The rad core was not designed to hold the weight and resist the motor starting torque...it'll rub and abrade the bars/fins until it leaks.
- Many in this thread don't seem to understand what the shroud is actually doing.
It's quite simple.
Air, just like water, can be considered a fluid in this scenario and like water, air will take the path of least resistance. The shroud forces the fan to draw through the core, rather than suck from the sides, which the fan is perfectly happy to do. Also, the shroud will space the fan off the core, which minimizes the "dead spot" under the motor housing, increasing the surface area being cooled. There are formulae to figure the ideal distance but practical considerations usually prevail and any distance is better than none. Finally, the shroud provides a sturdy platform to mount the fan, thus relieving the core of that duty.

The long/short here is USE A SHROUD.
The flexalite does have it's own built in shroud. Though it is smaller than the oem shroud I would assume is still creates a pocket to where the air would be navigated through.

yes im hearing your concerns with zip ties to the core but if done correctly a fan can be attatched to the core and problem free although it is preferable to mount it to the frame or end tanks if possible.
As to the shroud, there are two schools of thought, one being that a shroud can actually impede air flow at speed, and if the radiator core is shaped in such a way that a single fan covers it , ie a square 18x18 in this case with say a 16" fan then a shroud is almost redundant, especially if there are clearance issues. Almost all the bars are covered by the fan and the say, 80% area that the fan covers is getting superior flow to the 100% of the rad that would be getting covered by a shroud. It all evens out.
its a contentious issue and each to their own, but shroudless does work fine and i would say preferable to a poorly designed or fitted shroud. Of course an oem style shroud would have to be the best option but not always practical in a modified car.
Either way the thing should be air tight to the rad.
just sayin.

your sig says gtu, no mention of turbo swap.
is it a NA engine? do you still have AC?
your fan choices are almost wide open compared to FMIC cars especially if you took the AC out
tried and true taurus fan, already has a shroud- why experiment when there is no need to?

S5 NA with A/C. I'd favor having something brand new.
