Track debut today and no destructive problems. In ambient temps near 90, coolant stayed at under 200 deg F, Oil under 225 deg F, and Intake air temp peaked at 113 deg F at 10 psi boost. Logged oil pressure did drop to 30 psi in spots, but my beacon was not picking up so it was real hard to tell if that was just due to revs dropping on shifts or G-loads.

Bad news was that the LSD I tried (now I wonder if it was really installed) spun the crap out of the inside rear wheel in anything tight, but then again I have not done any suspension setup as I am awaiting the toe link fab work to be completed.

Fuel level was all over the place, so I do not know if my fuel starvation fix really works, although the car did not starve for fuel.

The Hydra auto tuning worked well and kept A/F at a conservative 11:1 under 10 psi boost. The Hass turbo hard parts (actually only the manifold and turbo with my mods) held up fine, albeit it was under 1 hour on track today so time will tell.

I need to get the suspension set up, may need to get adjstable sway bars (they are stock base model bars right now with track pack springs and dampers as part of the overall grab bag of internet deals that make up the car).

Then I need to figure out how the hell to tune the cam timing map, although the base map from Hydra EMS felt good and did not have the abrupt cam switch feel of the stock car.

Overall I am pretty pleased with a first outing since nothing exploded or fell off.
