Design Extruded 6063-T6 body Fully machined features Proprietary 6063-T6 FAS thermal CORE *Friction Stir Welded (FSW) lid for maximum heat transfer Retains stock hardware and placement * Friction Stir Welding is a patented technology only available through a licensed supplier.
Comparison FAS Oil to Air 160 sq in Al. to Air area 440 sq in Oil to Al. area Stock VW Oil to Water 40 sq in Alum. to Air area 112 sq in Oil to Al. ar ea
Advantages Reduced thermal load on the engine coolant system 4 times the amount of contact surface area for both oil and air over stock Eliminates the possibility of intermixing coolant and ATF as with previous design Easier installation with the removal of cooling lines
Thermal loading shown under natural convection Thermal Analysis
Testing *Thermal bench testing has shown the cooler to operate between 175-188F without air flow. * Testing was conducted at 74F with a completely rebuilt transmission running fully synthetic ATF at full load in 3 rd gear for 40 min.
