Oil cooler Idea

wstar

IMHO, it sounds too complicated to do one-off engineering like that for a track car (separate coolant path + PID controller and some kind of flow-switching, etc) and expect the parts and setup to be reliable. The best-known oil cooling solution that works reliably is to do a really good job (using quality hoses/parts!) setting up a 25- or 34- row Setrab cooler out in front of the radiator and skip the 2013 oil/water exchanger. If you want to take on a little first-time-installer engineering risk, I'd spend that on testing a Laminova setup + upsized radiator and getting those sized right for the car. You won't need fancy temp controllers. Given a sufficiently-large Laminova core, the oil temps will approximate the water temps (both on warmup and during track driving, presumably), and water temps will be stable unless the car overheats (get a bigger radiator and/or better fans/shrouding). With the right parts there you should see very stable oil+water temps somewhere in the ballpark of 202-230 depending on conditions, which is about as good as it gets.
