Howard uses the supplied tank clamps to secure the Peterson dry-sump tank to the roll cage. Before the car was sent off to LTMW for the interior paint, brackets for the dry-sump tank clamps were welded to the roll cage. In the future, we will need to make a sheet metal cover for it for safety and rules compliance.
Brackets were also welded to the cage for the breather tank mount. Ideally, the breather tank should be mounted outside of the driver’s compartment.
The dry sump tank and breather tank look great and are in plain view of carshow goers, but their location will need to change once the car is done with its “carshow tour”. Most motorsport sanctioning bodies require tanks to be divided from the driver’s compartment, so we will need to cover this piece of beauty with sheet metal before hitting the race track. The breather tank is definitely not a good idea to have in the driver compartment. Not only for the fumes, but in case of an accident or rollover oil can spill out of it.
Of course, we are running CSF’s new high tech oil cooler. The cooler is a bar and plate design with CSF’s unique extruded B-tube turbulators. This makes the plate look like the letter B laying on its back when cut open. The B-tube design gives much more internal contact area for better heat transfer and also makes for a much stronger plate that can tolerate more pressure and more external loads.
Unlike your typical oil cooler heat exchanger, you can bolt a CSF cooler directly in place and not have to bother with clamshell mounts since the core is so strong. A feature we really like is the built-in CNC machined biller mounting pads that are already drilled and tapped for mounting bolts. Like we said you can bolt directly to the super strong CFS bar and plate oil cooler!
The CSF oil cooler is not brazed together as is typical, but is tig welded which is much stronger. The welded in hose bungs are drilled and tapped for 1.5 x 22 threads so you can bolt AN fittings directly in place. Looking at the end tank you can see the welded in divider that makes the CSF cooler a double pass design. The oil must pass through the core twice. This improves the cooling efficiency by about 15% without adding any mass, size or weight.

Good stuff, but the fumes in the cabin will be unbearable with the catch tank in there. Even with my oil/catch tank mounted in the trunk area (which is sealed off from the driver compartment but not totally airtight) the cabin filled with strong fumes almost immediately so we had to run a breather line from the catch tank vent out the back of the car.
We completely agree and will definitely be moving the breather into the trunk. You’ll see our solutions in later articles when we start getting the car ready for track use.
isn’t that oil cooler about half the size of the stock one? I mean it looks a little bit thicker, but is that enough to make up losing about 1/2 the front surface area?
The stock oil cooler is taller but much more narrow. The CSF core is a lot more efficient.
