Just did my first DE with the new drivetrain. Fantastic! The first session was a bit uncomfortable. But considering that I hadn't been to any DEs in two years, not to this track (Blackhawk) in eight, and throw in a new motor and tranny, I wasn't surprised. By the second session, things started to click. I was always pleased with the handling and overall grip of the car, but the power was always lacking. Not any more. It really feels nicely balanced now. Motor ran great too, no hiccups, smoke, leaks. I was also happy to see that the oil temps never exceeded 230, and were usually not above 220 (ambient in the mid 80s). Tranny shifted beautifully. I could definitely feel the rear end hunker down more under deceleration with the LSD.
The one thing that this experience did highlight, is the need to move to a true track pad. I smoked the Hawk HP+ pads. I'll be using Hawk Blues for Road America in a couple weeks. I'll try some Motul 600 in place of the Super Blue as well.
