Cool Collar Oil Cooling?
 
Saw this on horsepower TV. To me it doesn't seem like it would do a heck of a lot. What do you guys think? To top it off they make some pretty wild claims. Has anyone tried it out? (especially if you have a gauge)

couldnt hurt.

Price is right. I might get one.

The amount of cooling will be very very small, if any. Hardly enough to make a noticeable difference.

Imagine that you have a standard running engine. Hot oil is constantly going in and out the oil filter. The oil filter gets hot from the heat of the hot oil. Also, consider that the engine itself,...gives off heat.

Even IF you had a direct source of cold air aimed directly at this "cooling collar",...quite simply from a physics standpoint,...it would be IMPOSSIBLE to produce any "significant" results.

Why?

Because the amount of surface area available to be used as a heat sink is VERY VERY small. (Same principles as how the brakes/rotors work). The BIGGER the rotors,...the more surface area to be used as a heat sink. The larger the surface area,...the faster it will help disappate heat.

Why are oil coolers, aluminum radiators, and intercoolers so big? Because they have a larger amount of surface area,...which in turn,...cools the air or fluid faster.

Could you use a small radiator to cool the coolant (for example)? Of course you can. BUT to match the same amount of "cooling" provided by a bigger radiator (in say Florida),...your car (now equipped w/ a small radiator) will have to relocated to Canada. Slight exageration, but you get the idea.

http://cool-collar.com/testing.htm

"Test Results: Laboratory Test

Castrol GTX 10W30 motor oil was heated to a temperature of 220ºF, and pumped simultaneously through two identical oil filters. One oil filter had a Cool Collar attached, the other filter did not. A fan was used to direct seventy degree F. ambient air over both oil filters at a velocity of fifty miles per hour. The oil exiting the filter having the Cool Collar installed indicated a "heat removal" of two degrees per minute. Whereas the oil temperature exiting the filter without the Cool Collar showed no change."

NOTICE: They had a jet of 70 degree air directed at a velocity of 50 miles per hour. This is CONSTANT air. Your engine bay does NOT get a constant rush of air flowing through it. (And I would be surprise if ANY engine bay gets wind flowing through it at 50+ miles per hour. A velocity of air (at 50mph) going through any moving vehicle's engine bay, can expect to either have the hood break off OR the car will end up airborne.).

I hope you guys understand what I'm saying.

You guys are better off w/ a properly working cooling system.

Cleaned/flushed oil coolers (or upgraded ones)
A properly working radiator (or a larger aluminum one)

I think you are absolutely right.

If it were capable of being effective (which I doubt), it would have to be mounted low on the engine and in an airstream. Some piston engines have the filter on the bottom in front, but with the high and aft mounting of the Rotary oil filter I would guess it wouldn't do squat. You might as well buy Slick 50 :D

An excellent point about the air flow especially considering what the oil cooler's function is, size & location.

You can send your money to those "cool collar" folks on TV or...

... you can paypal me $25 and I'll summon magical moths that will flutter around in your engine bay when you're at full throttle with the hood closed which will help circulate air and cool your engine.

Sad thing is... you'll get that same for your money either way.

Another damn autopart ripoff scam to add to the growing list

CrackHeadMel 09-26-03 10:48 AM

I once hurd on t.v. that some species of bee's use flapping of there wings in there hive to raise the temp of the hive to kill off enemy's during an attack

so wouldnt your flapping moths make our engine hotter?

i dono, i have to much time

John Magnuson 09-26-03 03:12 PM

Yes, but those are bees. They do that to kill Japanese Killer Wasps.

My moths provide only cooling. Or your money back.

DriveFast7 09-26-03 04:28 PM

Just route an air duct up to your oil cooler.

Or better yet, when I filled all the cracks and gaps in my 1st gen's front end with self expanding foam to make sure air must pass through radiator and oil cooler and not around; both oil and water temps dropped 10 degrees each per my autometer ultru-light gauges.

And it only cost four bucks.

artowar 09-26-03 09:54 PM

Man, that thing looks like a really good hand-shredding device....

swoop 09-28-03 02:35 PM

touch your oil filter while the engine is hot and you will find that the filter is not very hot. that cooler won't help any.
