There are two plugs on the casting tap in there. You will have both the internal oil cooler and the external oilcooler.

The Engineers knew what they were doing.
The oil goes from the pump to the filter then to the passage to the main bearings. A distance of a few inches. Why have the oil go from the oil pump to a line that is many feet long then back to the main bearings? The stock cooler is a bypass, using the oil gallerys in the oil cooler stand to plumb the external oil cooler.Your oil will not be taking a long winding path to reach the main bearings. A dry sump in the 911 engine is a completely different Oiling system than the wet sump of the type 4. The 911 oil travels from the tank to the pump and right to the bearings. The oil coler is on the scavange side not the pressure side. That's why a front mount cooler is fine to use with the Dry sump. |

A pic of the "bracket". I ain't that good with metal fabbing, but I'm hell on wheels with wood (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) That is 3/4 Oak plywood, screwed & glued, & fitted to the shape of the front bulkhead, then screwed & glued (using Vulcum calking) to the bulkhead....cobbled would be a gud word for the whole works. Attached thumbnail(s)

Air flow.
My set-up is sufficient to hold the temps under 100C durring 150 minutes of track time and 2 driver AXs on a 90 deg day. There are 2 things I could have done to improve the cooling had it been necessary. 1)More holes in the back bulkhead. I surmise that the area I vent to is either a low or neutral pressure area. It seems to vent *very* well there. The oil comes into the cooler "no touch hot" and leaves warm to the touch. 2)Sealing off the area between the bumper and the front bulkhead around the cutout.
