I'm actually going to do this on our spyder this winter. I've thought alot about it and it will work. Eventually. The thing that will make it really slow to work is the thermostat at the oil cooler... Takes awhile for the oil to get warm enough to even open that (think it opens at 167 or something like that). Then the line to the second cooler that I'll install. Pretty good temperature drop. But I want/need the 2nd cooler anyway, so why not scavenge some heat off of it. Steve's a dang fined handy fabricator. If I can come up with an idea - he can make it. Like to use a cable arrangement to open/close it and a fan to drive it. In the cockpit closed position, the heat would go out of the car - just an oil cooler. In the cockpit open position, the assembly would drive the heat (w/blower) into the cockpit.

Of course, with some more pictures, maybe I would just use this little setup - looks awfully uncomplicated and that would mean I could do all of it and not bother my long suffering husband.

One of the "things on angela's list to figure out/do this winter..."

I was going to put it in the well underneath the gas tank. No beam on my car, so it looks like it would fit just fine. Mount it upright at the wall that seperates the passenger compartment from that area (outside of the passenger compartment). Ducting should be pretty easy in that case. Looking at a long cooler short height like an RX7 cooler.

The engine builder I'll use this winter highly suggested a 2nd cooler. The 3.0 came with two and right now I just have the engine mounted one. No problem in this state of tune on this car, but next state of tune, this could be an issue. Since I need more cooling capacity for that motor, why not build a heater out of it?

I don't want a nose mounted cooler. I quite enjoy my trunk space. With the battery mounted mid-ship and no cooler up there, I actually can put quite a bit in the nose of the little car. My laptop case complete with printer, spares for the car, tools, a jack and a couple of duffle bags all fit right now. Helps extend my adventures! angela
Seems steel braided lines would suffice to prevent leaks in the lines. Aircraft fittings should be a tight enough fit as well.

Wonder if there is enough room between the wall and the front tubes/steering mechanism to fit the cooling unit?

Also, do you think it and the extra line will create a reduction in oil pressure?
All the lines are stainless on my car, all the fittings are aircraft style. The oil pressure is pretty high when it is cold - on the pressure side factory uses hardlines for a reason. Plan to run the lines thru the side pods (insulated) thru conduit tubing as the wiring is also run on this car. That keeps the hot bits out of the passenger area. The 911s 3.0 have two oil coolers from the factory. One on the engine and the other usually in the front fender (some models in the nose) with hard lines running underneath the car. Oil pressure is not a problem with this oil pump. Basically emulating the factory setup except the cooler will be located in a place to use as a heater. In fact, the factory setup on a 3.0 SC is what gave me the idea for using it as a heater.

If you stopped to think about it, water cooled cars put the heater core inside the cockpit with rubber hoses. At least the oil cooler itself on the setup I propose remains outside the passenger area.

The front of my car has different steering. Uses a rack and pinion mounted to the frame. Right now I have my fuel pump, filter and regulator in the well along with the master cylinder. Have to keep things small, but at the rear of the well/bulkhead to passenger compartment, there is enough room for this to be mounted.

This will work. Not as nicely as a water heater core, but it will work. angela
It sounds like this will work only if you live in a cool enough environment. Porsche first felt it needed a second oil cooler on the 2.7L 911s. Though your car is half the weight of the SC your 3.0L came out of, that secondary cooler will probably only be really needed in the summer time - when you won't want any cabin heat. I'm not sure how long you have had this set up, but if you have found that a secondary cooler isn't needed even in the hotter times of the year, then go for it. Otherwise, you'll be driving solo after pulling a "hold on baby, it's going to get a bit warmer - I need to drop the engine temp a bit"..
