alternative oil cooler

[nostatic]

Has anyone used the oil cooler that replaces the S-tube out of the oil tank? Does it work?

[Alan Cottrill]

I've searched old threads on this one and the cool collar.

lots of theory and opinion but not one post where someone said "I installed this product and my oil temperature changed x degrees at an ambient temp of y after z miles"

when I see that post I'll make a buying decision.

Here's more opinion. Can you estimate how many seconds the oil is in that device? If it is only a few seconds, as l kind of suspect, it seems unlikely to transfer much heat. Which might be a blessing, as this so called cooler is just inches from the heat exchangers. How come we want heat shields between the valve cover and the HE but we're happy to have our oil cooler just as close by? Chuck Moreland's finned oil lines make so much more sense.

Jack O was running it on his BB 1. Unsure if he's still using it.

If I had the extra $ I would do a independent test on it, and report my findings.

Jack O. is not using it any longer , when he changed his headers there was an interferance with the cooler.

Someone on Pelican has to be using one of these don't they? Or maybe Jack can chime in on the effectivness while he had it on?

Looking at the tube and how it is constructed....I began thinking about the oil return tubes.
I wonder if making a set of finned return tubes would benefit cooling.
The tubes are the last part of the engine that the cooling air passes over....and if the tubes were finned and perhaps black anodised...maybe they would add some cooling capacity.
Just a thought...because I need new tubes anyway.

Man, I think it would be a bear to get finned tubes up into where the return tubes go, besides the issue with the telescoping. Unless of course you go with the original version.

I would like to have one but it will not clear the B$B headers. In prior posts I think results of about 5 degrees were recorded.

edit: I went to change to "$" between "B" and "B" to a "&", but now that I think of it the B"$"B really makes more sense.

Having just become a new father for the second time here is my unscientific opinion.

My tap water gets to about 120 degrees while my fridge gets to around 40.

A 3 ounce bottle of 40 degree breast milk immersed in a bowl of 120 degree water takes about 5 minutes to bring the water temp down to around 70.

IMHO the oil will not be in there long enough to make a diff.

Then again I'm sleep deprived so what do I know.

I like my finned lines from elephant. And stomachmonkey gets the best post of the week award.

pbs911, please direct me to the post that stated a 5 degee reduction, i must have missed that one. I have had the cooler on my car for almost 2 years and consistantly show a 15 degree reduction in temps over a wide range of driving conditions.The cooler has over 500sq. in. of surface area on the outside and 300 sq. in. of surface area on the inside that provides for a large amount of heat transfer that is is carried away in the air flow under the car.

JMPRO,

you are about to help me make a buying decision.

the only time I'm concerned about my oil temp is on 90+ degree days when I drive a little hard.

Do you experience the 15 degree drop in similar conditions?

[stomachmonkey]

OK, how bout this.

They come in various lengths, 3, 4 and 5 ft.

Trying to find the overall outside diameter but I'm thinking, especially for those that have crushed lines.

Could you take your oil return lines that run under the rocker, cut a section out of the middle, tap the ends, install fittings and replace with this?

Jerry, Not doubting you, (because I have no idea how well these things work), but how are you arriving at *15deg. lower temps*? I would think that you would have to take a drive on a specified, (hot), route, record temps, then install the device and immediately take the same drive at the exact same speeds/loads, with something a lot more accurate than a stock oil temp guage, since 15deg.F is not readable one way or the other on our guages.

If you have done something like this and already reported it here, I apologize, just never saw it.

[JMPRO]

Scott, i looked into the possibility of doing just what you described but the size of the cooler is 3"od and may present a clearance prob for some cars{lowered cars and race cars}.If somone wants to put up the money for tooling, a flat oval tube could be extruded that would have a low cross section that could do the job, but then you are in a high expence, hard to install part.
Speeder, I tested the cooler just as you described using a IR thermometer to record temps from various places to estalblish a baseline for before and after data. The dash gauge is actually more accurate than you may think and if you use " 1 needle width=5 d." you can get pretty close.

This problem has already been solved. And you can buy the product from pelican to boot.

Scott, those tubes you picture are simply too big in diameter to fit under our cars.

[stomachmonkey]

They recommend a clamp on ballast bracket and the part number corresponds to one that is used for 1 3/4 tubing.

So they are not as large as we may have initially assumed. Depending on what it is made out of you might even be able to plane it down on one side to get a bit more clearence.

Chuck,

I actually thought about your excellent product which has received high marks from many satisfied customers on this board.

I don't have a cooling problem or crushed lines and stumbled accross this product while researching something else.

You have to admit that not everyone has the $600 for the Elephant lines and some guys might actually enjoy fabricating something on their own for the satisfaction of having done it.

$30 for the part and maybe $50 in fittings, some simple tooling and who knows, it may not be the better mouse trap but it could still work.

Gotta keep thinking out of the box.

Scott, when i looked at the website i got the idea that the price was per foot, you might want to check that. The other thing is the outlet size is only 3/4" . That could be too small. Also it says "low press line" may be not strong enough.Different mouse traps are fine.

I worry because it is on the wrong side of the thermostat (I think). In other words, you can't avoid the cooling when the engine is cold.

I could be wrong though
