Track Day Chat

I just did a 1400 mile round roadtrip to a track day event in Central México.

My 09 did pretty decent lap times (255,305 Pzero helped a lot)

However I did not have a chance to install and test the oil cooler, trans cooler and oil pressure gauge before the trip. I definitely didn't want to blow up in the middle of the highway. Oil temps were 250-265 and I slowed down past 265. I had enough "heat" margin to do one or two hot laps with cooldown in between. Never got to limp mode. Tranny was sluggish almost at the end of two sessions (out of 7) and also had to cool down. No diff or brake issues (non sport brakes with VLSD)

I will be installing all of this soon and test it on the next local track day!

BTW, the oil temp cannot keep up with highway cruise speeds of over 110 mph on hills or 130+ MPH pulls for over 3 minutes

. It definitively needs coolers. Cruise control doesn´t work over 90 MPH too. Don't get surprised, mexican toll highways are great, traffic moves FAST, better in the weekend mornings with little traffic

I was amazed, the car is decently comfortable for long trips and drives great at high speeds on the highway.

By the way, for the mexican hot summer (110+F) and spirited driving with occasional track days, do you guys recommend moving to 5W40? I use 5W30 Mobil 1.
