Sorry to hear that Javad, that's one way to really
screw up your weekend.  As far as the EGT's go, 1000 C
after the turbine is retarded!  When I was at the dyno
I was hitting about the same temp near redline, but 6"
away from the valve.  I actually dropped the fuel
mixture down into the 11's at that level to keep
things closer to 1700 degree's F.

Later,
