Brainstorm: Aftermarket dry sump tank location

[Shuie]

At the moment, this is hypothetical. I do own a ’72 that might get a 3.6 swap in the future so please tolerate me for a few minutes.

We all know Tyson expanded BBIIs oil tank for the 3.6 swap into Jacks car due to the track use the car would be subjected to and the lower than normal capacity of the stock ’72 tank. Other than BBII, just about every post I’ve seen here documenting a 3.6 swap into an early car shows that the owner has retained the stock tank. I’m assuming that a front cooler and a set of lines add enough capacity to a ’72 oil system for a 3.6 street car. Okay, fine.

The car that I will begin to work on in the near future is a '72 that will more than likely be built as a street legal track car. With a rollbar in place and almost no interior, I can’t imagine having any use at all for the back seat of the car.

I found an old post about Minkoff’s track car that shows a couple of pictures of his beer keg dry sump oil tank mounted inside of his cage on the passenger side of the car That got me thinking, ‘Why not mount it in the rear passenger side seat bucket that I won’t be able to use for anything once the rollbar is in place?’



This would effectively move the tank closer to the suction side of the motor. This would be probably be a better benefit than the weight distribution benefit of putting it in he smugglers box or in the front of the car. It doesn’t seem too unsafe since the tank the would be enclosed between the braces of rollbar. Capacity obviously would be an issue since this thing holds 9 quarts by itself and a cooler & lines would take total capacity to 15 quarts+.

Can you guys see anything wrong with this logic? I know I would have to get out the holesaw to clear a path for a completely custom set of oil lines.

Am I trivializing a potential safety issue?

Would the radiant heat be too much inside the passenger compartment of the car.

What about the drain on the tank? How do you drain one of these tanks?

What about the height of the height of the bottom of the tank? Does it matter that this tank would sit higher than a stock tank does? Would this tank location create any oil flow or pressure issues?

TIA

Sherman,

I have posted on this several times. I think there should be an aftermarket oil sump tank in place of the engine mounted oil cooler. It can fit all the 911s. Follow the example of the GT3-RSR. The oil pressurized cooler can be easily repositioned. Someone is missing the boat here.

Best,
Grady

Some race organizations (and some would say: good sense) require some type of structure between the driver and over 2 gallons of boiling-hot oil.

Expanding the 72 tanks seems far less involved than plumbing in an aftermarket tank. (And in my case, I carry stuff to the track in those back seats.)

But If you're set on an aftermarket tank, why not put it up in the smuggler's compartment, for some really meaningful weight redistribution?
