Well, after gleaning info from the generous members of this board, the XT6 was race-worthy.  Trailered it out to the site and ran it hard.  Made it through 4 of the 6 runs before I totally lost oil pressure.  Looks like I'll need to pull the pump and see what's wrong.  Engine was running hotter than I thought it should too, almost got into the red by run 3.  Hopped into the WRX for the last 2 runs, but didn't have time to adapt to the extra power.  The Lincoln Locker really helped the power-on oversteer. Notice the BMW X5 and the new EVO VIII that came out to play!   Anyway, I've linked the pics from the event below. 56K beware
