In racing conditions engine oil temperature skyrockets. This causes decreased engine performance and reduces the oil's ability to properly lubricate. A well designed engine oil cooling system like the PERRIN Oil Cooler Kit will help keep temperatures within the desired temperature range, thus maintaining performance and prolonging engine life. Most setups can see a drop of approximately 15°-20°F at 7000 RPM.
Each PERRIN oil cooler uses a Setrab core which maximizes heat dissipation without pressure build-up. Oil-ways are interspaced with airway corrugations providing optimum heat transfer, while the oil passages use "turbulators" to break down boundary layer effects in the oil flow.
Setrab Oil Coolers employ an in-line turbulator to gently stir the fluid being cooled, thereby ensuring that the fluid has exposure to the entire internal surface area of the oil cooler with the least pressure lost. The turbulators are fully brazed to the entire internal length of the tube resulting in zero heat transfer barrier and high strength.
The PERRIN Filter Adapter features an integrated 85°C (185°F) thermostat. This means your oil will reach its optimum temperature of 85°C much faster.
In addition to the OEM oil filter from Subaru, we include a PERRIN spacer which allows for easier installation of the thermostat-filter assembly.
The PERRIN Oil Cooler comes with custom brackets that allow the oil cooler core to mount directly to existing holes in the OEM core support of your vehicle. Made from CNC machined 6061 T6 aluminum, the brackets look sleek and stylish while blending seamlessly behind your bumper.
The PERRIN Oil Cooler kit uses lightweight Aeroquip brand -10 hose that is rated for 250psi and 300°F continuous temperature. Each hose consists of anodized -10 push-lock type aluminum hose ends. These fittings are designed to fit without the need for clamps, but we take the extra step and add a clamp ensuring they will never come apart. Unlike other kits that make you assemble your hoses, PERRIN preassembles them for you!
PERRIN's hoses are made using Industrial grade Pyrojacket. Pyrojacket withstand continuous exposure to 500° F (260°C); up to 2000°F (1090°C) for 15-20 minutes; and up to 3000°F (1650°C) for 15-30 seconds. When exposed to flame, the silicone rubber transforms into a crust, creating a protective SiO2 refractory layer.
