New Track Tire Setup and AT Cooler version 2.0 (10-31-15)
Apologies for the delayed posts as my laptop decided to quit on me.
During my last trackday, I had the chance to try out my new track tire setup, and how the bar and fin tranny cooler I installed would fare. The new track tire setup consists of an 8.5/235 front and 9.5/265 rear. I currently am running Rotas as I'm saving up for some real TE37s.
Rear end grip really improved as I can power out earlier then with my earlier square setup. I did not feel any understeer with the staggered setup.
The tranny cooler was another story. As soon as I had some WOT runs, after lap 3, my tranny was running really hot. 130C hot. The truth came out this time because we were using the long track configuration and therefore had more WOT time. The small bar and fin cooler got overwhelmed quickly, and with little direct airflow, could not cool the tranny fast enough.
I had another B&M AT cooler lying around and I decided to just place it behind the intercooler. I was hesitant at first with this setup because I didn't want more heat exchangers stuffed out front of the radiator and AC condenser.
The cooler fits, and it is a very tight one to be exact. Driving on the street, it cools a lot more than the previous setup as seen from my AT oil temp guage. I have to try it out on track again to see if there is a difference. I will report my findings after my next trackday.
