Well I pulled the head yesterday and found 2 melted pistons...
1 and 6



This is the #6 piston on the original motor - december 08

this is a cold engine start up, smoked and missed, till engine got warm.

This is the "new" motor after 1000 miles - January 09
#6 piston

#1 Piston

We live at over 6000 feet elevation, havent looked at the egt gauge lately on a Wot run, but i believe it hits 1600 in the 1/4 not sure in the 1/8,
Happened with smarty TNT-R on SW9, Timing Default (2)
MP8 = 100%

opinions are welcome

i hate to say it bro... i did a similiar thing with what your damage shows. can you change the tnt-race from stock timing? seems like stock timing would be too much with big injectors!

i won't run stock timing ever again. plus i was running tst auto timing, and watermeth. just seemed to be a bad combo all around.
