Interesting piece I found at Garfinkle's

looks like an interesting way to cool oil without extra hoses or radiators







I have more pics if thats not enough

That's an awesome idea, however with all those tubes, how much volume is it reduced by, 1/2 to 1 quart?

I think 6 tubes along the center section would be enough plus it might even help with oil sloshing around.

Randomly thinking about this...
By increasing the surface area of the oil, heat transferred (to the atmosphere) is increased. Though, you are reducing the oil capacity (because of the tubes) and less oil will pull less heat energy out of the motor.

Why not just upgrade your oil cooler and/or ducting to work better? Then you don't have to run with less oil...

Why run with less oil just remark the dip stick ,did you think the oil pan and above is full to the max .The stock pan holds about three qts ,the rest is in the cooler, hoses and above the pan .

David,

Interesting idea.. Are any of the pipings interfere with the pick up?? I wouldn't mind giving this a shot.. We'll talk this weekend. Can you bring it with you?? I also have like 6-7 FD oil pans

The tubes are around the pick up that is why the pattern is odd .

My question is... how much airflow would even get to the tubes? The oilpan on a stock FD sits up inside the subframe, with only the lower half inch, or inch, being exposed to the air rushing by underneath.

I'd say for this to work as well as possible the pan (and the tubes) should extend down another inch or 2, like the pineapple pan. Otherwise it's about equivalent to putting your hand out your open window while at speed, and laying it behind your mirror...it gets very little air volume, while the majority of the air is directed around it by the mirror.

You've hit on the reason I think this would not work very well. Heat transfer to air is by far the least efficient part of the heat-transfer process. You need something like 10 times the air-metal area as you need for oil-metal area. And when the air-flow is slow, you need even more. Then there's the length of the tubes - by the time the air gets 1/4th of the way through, it would already be hot and unable to pick up any more heat.

Might be worthwhile, if you do intend to make this work, to fab some short of ram duct to draw air up and into the leading face of the pan. But then, for lowered FD's this is just asking for trouble.

No fan is in the plan but a small scoop is, and the car is lowered . This has more metal to air area then stock ,Even if it works to cool the oil at highway speeds a few degrees then it is a positive thing for the life of the motor ,with out spending the amount for two oil coolers and the lines ,connectors , time to install and clean and comb the fins .
