Cool Collar works????

[mbuhrig]

I just added a Cool Collar this weekend. I read it should drop the engine temp by about 12%. It certainly seems to be working great for the low cost. Here in Miami, in traffic with AC on my temp was shooting to about 250f and holding (little over top white mark). It now seems to sit just a little under the top white mark under same conditions. Is this temp OK? Most driving I do the needle sits a little over the second white mark.
Thanks for any input!

250 is too damn hot!
I am currently working the cooling issue as well, and I have the cool collar installed. I think this may work well on some vehicles, but I don't think it is able to produce the results listed on our pcars...12% is a little high IMHO.

I have noticed better cooling from the air duct I have installed in the front passenger side turn signal assembly. This is like the one sold in tweeks, performance, and I think pelican...but mine was hand made and best of all....FREE!
I have noticed a consistant average drop from 230 to 220 with this in place...of course it only works if you have the loop/carerra cooler installed.

Oh, island911...where are youuuuuu????

It's funny that when you do the math to figure out what percent of cooling improvement you get as a result of the cool collar, your resultis different if you use the F or C scale.

Anybody who actually does work with thermal dynamics knows that you should be working in degrees Kelvin (from absolute zero). If you use degrees Kelvin, the "claimed" cooling effect is less than 1%.

Mbuhrig, a car as great as an SC should not get that hot! I hope you can get the temperatures way down somehow. Maybe something like a Carrera front coller with a fan and some air flow like Mr. K9hander so skillfully fabricated.

Sorry no disrepect to the fine invention Cool Collar, I meant the above cooling system to work with, to complement , the Cool Collar.

K9handler, a very nice attempt to copy my original design on the cooler scoop
[commissions due?} . I am glad to hear you have shown a 10 degree drop in temps with it although your opening is a little smaller than my original design. Now if i can just get the cool collar in the scoop for a double whammy.

The car IS getting excessively hot, however typically when stuck in traffic on a 95 F day (and much hotter off the pavement) with AC on, for 45 minutes or so. What should be expected temp with a basically stock SC?

I have now read a lot of threads on Cool Collars and a lot of the learned Pcar enthusiasts don't have a lot of good things to say about them. Without talking any numbers (Kelvin, Fahrenheit, Celsius or otherwise) I DO see a definite decrease in temp... now I am not sure if that has any adverse effects anywhere else (that heat only has one place to go), but until I decide if I want to install a Carrera Oil Cooler it puts my mind at ease.

Thanks for all the input,
Marc

PS JMPRO your cooler scoop will be my next attempt at lowering temps. By the way, I think all of these SIMPLE ideas are great and I believe that is what owning one of these older Pcars is all about (amoung other things ).

Jerry,
here is how it was made.

1. Toilet paper roll
1. Dr Pepper Can
1. Roll of electrical tape
1. Can of black spray paint
1. Fiberglass kit

The design was made by a friend in a matter of hours with the items listed above. Once it was all taped together, he covered the mold with fiberglass and then painted it black. We installed it the next morning using the bolts originally used by the reflector.
McGyver could not have done it any better!

Most people that have installed the scoop have reported from a 5 degree to a 10 degree reduction in temps, which is a very satisfactory outcome for such a small investment.
But as one poster commented," you have to be moving for the scoop to work". Duh- i think that likely applies to all areo effects.
My first scoop was fabed out of exhaust tubing and flat stock. The 2nd one was made of wood { which my neighbor thought looked very cool, kind of that Porsche meets Martha Stewart look} and then the final design which has won the hearts and minds of Porsche owners the world over.{ well almost kinda}. The next step is to form the CSWDP club, that is the COOLER SCOOP WORLD DOMINATION PLOT.

There is sufficient anecdotal evidence to warrant purchasing the cool collar. And I'm gonna order one. Just keep in mind, we mustn't expect results akin to those on the Vette given by the manufacturer because our volume of oil is probably at least double what his is. Since we're dealing with a greater volume, we cannot expect the same results--but like anything else, you weave your improvements a thread at a time. If the cool collar helps a little, well, then it's worth it for the cost.
I'm gonna go ahead and order one.

[JMPRO]

Kurt, you might ask pelican if they are still running the deal where you get a free oil filter when you buy the Cool Collar. Also don"t forget the cooler scoop, that can give you another 5-10 degrees of cooling potential. The scoop can provide about 500 cfm of air to the oil cooler at freeway speeds and the air going into the cooler is at a lower temp than air going under the front valance because it is collected higher off the pavement which can translate into as much as 20 degrees cooler air into the oil cooler.

A guy who bought one of those scoops told me the Best way to install one of these things(for max cooling) is; Remove side marker to allow room for scoop . . .then STOP. . . do not go any further.

Seems he made the mistake of actually installing the thing; which would make the opening to the oilcooler smaller.

Of course this setup kind of makes his car look like a smiling hockey player. . .but cool.

[k9handler]

hmmm...I thought the same thing. But the maker of mine is an aircraft mechanic and he stated the design of the opening and shaft actually increase the speed of the air, the external part you see is just the beginning of mine...the air shaft goes in another 5" directing the air where it needs to be.

[island911]

Air volume moving over the oilcooler is key.
This guy had a large (for fender mount) finned oilcooler. So I suppose it's possible the the directed flow is better for something smaller. . . is your oil cooler the size of the directed flow opening?

[k9handler]

no it it not the same size...this is the beginning of the oil cooler upgrades. I am going to go with the fin cooler, and we are going to make a stone shield/shroud that will only allow air to pass through the cooler instead of around it. The exit end of the shaft is 4" in diameter and directly in front of the cooler placement.

[JMPRO]

As with most modifications the cooler scoop is a compromise, if you want to drive around with a hole in your car where once was a light, then do it. You could also cut big holes in the fenders and hood to let more air in. The problem is , most people do not want to cut up thier cars just for a occasional romp at the track so the alternitive is something like the cooler scoop. The scoop requires no permenent mods to the car and can be removed very easly should it be necessary {for show car events etc} . In fact the scoop collects more air than if the side light were removed and no scoop provided.

[k9handler]

I am with you Jerry.

[mbuhrig]

I also agree with you guys and it will be my next step. Only thing now is, after originally posting this “Cool Collar” question is should I never mention “COOL COLLAR” again? BTW K9handler, I read your posts on your car domain site… that was some of the funniest things I have ever read “speed of light…” … that was classic!
