Just came back from a track day at Sepang. As expected, my transmission recorded a peak of 123deg within 3 laps, which I then went back to the pits to cool down and then out again after it cooled down. Just like to ask for advice on transmission and other coolers for track. I'm quite keen on the HKS transmission cooler. Is there 2 types? ie HKS and HKS Kansai type. Which would be better? And I heard MB has their own in house cooler too. Any comments on that?
So after fitting a transmission cooler, how many laps can the GTR last on Sepang without the transmission crossing 130deg? Which I read is the critical point. After the transmission is settled, would then the engine/brakes/gears need additional cooling? I aim to be able to do at least 10 laps (preferable 20+) without having to stop and without damaging the car.
I'm quite surprise the design of the stock GTR which is considered a super car, only allows it to last 3+ laps around a circuit. Does the Ferrari or Lamborghini suffer from overheating issues as well? Or is it our local weather?
