I can tell you at button willow on a 90 degree day I could barely do one lap without my oil temps touching 280. Stock ppk flash, fbo, stock coolant, heater on full blast. My car is DCT. The radiator on DCT/at cars has two separate circuits, one for the motor, and one for the transmission heat exchanger, so we may see increasing temps in less severe scenarios compare to MT cars.
I think the csf radiator may be the best first modification, then oil cooler. If that doesn't work then I would consider replacing the trans heat exchanger with a stand alone cooler, then I could run a MT csf radiator which would now be cooling engine only, and then upgraded oil cooler.
I'm hoping the radiator upgrade will do the trick. As I would prefer not to plumb a trans cooler.
Would love to here how the csf oil cooler performs. Such a simple install.
