I just won an auction for a HotRod Air 2700 cfm fan and shroud for a 65-66 Mustang. I just couldn't pass it up for $120!! If anyone has one of these, let me know how you like it. I'll be putting it on my '66 331 stroker project.

I bought the same unit (less wiring) for my 67-302 3 row rad (17x20 bigger shroud): It made a HUGE difference in cooling, my niddle used to get to the middle of the gage (sometime 60% in 105+ weather). It now no longer exceeds 10%-20% !! It is super silent but will draw 9 amps (with a spike at 30 !! when starting). Make sure to use a 30 amp relay and that your alternator is in good shape. I would recommend to pay attention that the shrouds fits tight against the rad, I used black sealer where there was holes. I paid 209$ though

I purchased that same fan (minus the extra wiring) for $150 from a vendor at the Columbus Ford swap meet this spring. It pulls HUGE air, is only 3.19" thick, and the shroud measures a compact 15-3/4" x 15-3/4"... which fits 65-66 mustang radiators PERFECT. The shroud is great. I sealed it to the radiator using foam weather stripping that is sticky on both sides. After I got it all assembled to the radiator, I hooked the assembly up to a 40amp battery charger and turned it on to see how much power it drew, and the (cheap) gauge showed 19 amps! It is advertised to draw 22 amps! It's a beast!

After recieving it, I saw it was a Derale part #16926. Out of curiosity, I called Summit and asked if they carried the unit, and how much it cost. They said it would take a couple weeks to get, since they would have to special order the thing... but the price was just under $120.

It's a killer fan, and comes highly recommended for early stangs.

Good Luck!

Thanks Pierre and Mike, that's good news! My 3 row rad and 4 blade fan would tend to overheat when sitting in traffic and staging when I was running the 320 HP 302, so hopefully this, along with the new Flowcooler alum. waterpump, will take care of that problem.

Maybe my alternator and reg. should be OK since it has never let the lights go dim or flicker, but I do remember the dash lights bumping dim when I kicked on the AMP for the sound system.

Mike must be correct, 9 amps was with the fan free not under load !!

Unless you stuck that fan in a vacuum chamber, or removed the blade, it was under load. That peskey air, it tends to be everywhere.

JKilroy,
Hum......Try to breath air with your mouth opened (fan free from rad) then with a cloth in front of it (rad applied), you will feel a load. Resistance increasing on the fan, electricity consumption will rise: Sorry, I forgot the name of the nucklehead that came up with this law

I don't want to start a long argument, but... A fan can coast and draw very little power if it doesn't have any "fresh" air to move. The more "fresh" air that it draws in and pushes out, then the more power the motor will draw. A shroud will make it move more air and draw more power by concentrating the incoming "fresh" air through the blades. That tells me that a fan would draw more power if it doesn't have a radiator to slow the flow. If you don't believe me, then put your hand over a vacuum cleaner hose and you will hear the motor speed up because it doesn't have any "fresh air to move.

That's an interesting idea, Bluestreak... Might have to do some testing.

Anyway, the point is the Derale #16926 has got to be the BEST fan out there for a 65-66 mustang. It pulls killer air, is very thin (3-1/4"), and it's shroud fits the radiator perfect. Price is reasonable as well... Just under $120 from Summit. It looks like some sort of OEM fan. The quality is first rate.

In you're in the market for an electric fan for a 65-66 mustang, this is the one to get. It's the same unit HOT ROD AIR sells for their 65-66 air conditioning setups. (which require extra airflow)

Just be sure the car's alternator is in good shape and use a relay, since it pulls around 20 amps!

Good Luck!

Hey Mike,

Where'd you get your cowl hood? How is the fit? Did you have to do anything to make it fit?

I got the hood directly from Maier Racing in California. It's the same hood Musangs Plus sells.

Mine doesn't fit that well. If you were building a car for showing, you'd be disappointed. From what I've read, I get the feeling that if you live close to Maier (driving distance), you'll get decent parts... they save the crap to send long distances, where it's too expensive to return it!

My $0.02

Good Luck!

I agree with Mike, buy one as close to home as possible because fiberglass parts can be a nightmare if you get a bad part. You get what what you pay for.. and Nice well fitting parts sell at a premium. The same type hoods can sell from $200 to $600 dollars and the only difference is quality and finish! I bought one from Unlimited Products in California through mail order and was really disappointed in the craftsmanship and service. I think they are more geared for Racer type lightweight parts that are expendable. My advice is to get one from a trusted supplier like Mustangs Plus or Mustangs Unlimited if you want a nice street hood.
