Tiger fan comparison with pictures

[boss-tiger]

Opportunity to do visual comparison of Tiger engine fans, thought it may be of interest values. Chart matches pictures.

Description	Diameter	Hub Center	# Blades	Backspace from front of hub	Front Space From back of hub	Hub Thickness	Blade Thickness	Max Blade Width	Color	Notes
orig stock Tiger	14"	1"	4	1"	7/8"	1/8"	1/16"	3 7/8"	black	max blade width near hub, less 1 3/4 at tip
LAT - 6 blade, G-65	15"	1"	6	9/16"	11/16"	1/8"	1/16"	3 1/16"	black	believe orig LAT, low pitch

I believe the only one which comes originally with a 1" hub hole is the LAT - 6 blade, G-65 fan.

How is the CF-C7TA-G Canada fan marked? Which fan in the photo is it.

shoot I guess I forgot to include it in the pictures . Will try to redo tomorrow and include it

I have the Derale fan on my car. Even with 1/8" shims under new motor mounts I had to trim the ends of the blades to avoid interference with the steering rack. I trimmed the blades flush with the thicker piece of stainless that that can be seen in the photos. I also put a larger radius on the corners of the blades.

As mentioned, in the chart, all the pitch is to the rear and it sits very close to the upper radiator hose. I trimmed the hose at the thermostat end to move it back and have about 1/4" clearance without the engine running. The fan flexes forward as the engine revs so the clearance increases.

This fan sits about 1" behind the radiator which is a good distance. It pulls a ton of air. I modified the shroud to direct air through the radiator and at idle, if I toss a small piece of paper at the front of the radiator it instantly gets sucked up against it. I'm also using one of Hoghead's reduced diameter pulleys.

My stock motor mount shims look like .25" + the heat shield thickness. I never did measure...........

I still need to put up a pic of the CF-C7TA-G Canada 6 blade (at work now, goal is to post latter today),

LEFT - top fan is Derale, bottom is Flex-a-lite

RIGHT - top is stock Tiger, middle is G-65 (orig. LAT), bottom is CF C9DE-a P13465

I have been using a later model aluminum thermostate housing with hose end that swivels to obtain additional fan <> upper hose clearance. You can easily get these online and then using die grider cut out additional clearance for bypass hose (plenty of aluminum thickness to work with FYI).

Yep, on the swivel t-stat housing, I have been running them on the Mustang for years, but didn't think of tossing one on the Tiger. The stockish one I have on the car now with the right angle lines I made up look to clear the fan but totally forgot about the swivel type which can make things a lot easier to get the hoses where you need them. I'm sure I'll have to redo it as everything looks OK on the Tiger until you try to actually fit it up

Here are the CF-C7TA-G fan pictures that I forgot to include in this posting. I do like the looks of this fan and ? if that kick up at tip of blades increases effeciency (looks aggressive and cool IMO).

That's a fan I've never seen! I have the one on the bottom right of your original pics and it works great. Drove to Seattle and back (520 miles). Yesterday coming home it was close to 100 degrees, The car ran no hotter than 80 C. the entire trip.

Wow, that has some serious pitch in the blades! I bet it moves a lot of air, is there enough distance between the water pump and the radiator?

Not sure about a stock Tiger, but some of the fans with a lot of the blade forward of the hub was a problem for me. I'm running a Fluidyne 3 pass and have the motor pushed back a bit and ran into an issue with the fan that I though was going to work, super cool design with removable blades. But I could not get it to work with it either having blades get into the radiator or if removing the spacers the rear hitting the belts. I have Dale's Tiger pulley's on the car with a Victor water pump. I also have the pump flange pushed back as appropriate for the stock Tiger. I think I ended up with the stainless flex fans and a plastic fan that would fit. I liked the Fan I was hoping to fit as you could remove or add blades (track/street) use. The twist on the blades just didn't work on the Tiger

 

[boss-tiger]

Never seen a build your own fan before - cool. Let us know how it works. BTW, it looks very cool

 

[sandy]

It was an expensive really good try, you get the hub, pick the diameter of blades and put it together. I have run a 2 blade flex fan for years on my Mustang, and like the idea of the universal fan, but the pitch won't work on my Tiger as mentioned, just too wide and can't move away from fan belt as it gets too close to radiator. Will try to get it on the Mustang at some point. The one thing that is a downside (besides being expensive) is it's heavier then a flexfan or the nylon fan I'm going to use. Don't think that matters much but just something I noticed about it. It's nice, for sure.
