well, it was bound to happen. i spent all friday night at 8psi, many many races, including some top end runs against zulaters 01 Z28(damn my car runs hard over 120) and then spent the whole morning on 5psi at the auto-X(damn i never thought i could spin a fwd car so easy). im throwing a 71 now, even with new plugs and reseated wires. at the autocross i also noticed smoke from the breather vent, and mucho black crap from the tailpipe, all over the back of the car. i also threw the dipstick, making a really cool smoke show, but thats just because of the wonderfull drag manifold melting the seal. so im doing a compression test this morning, but anyone have any guesses on the damage? BTW, 97 ITR drag 3,

Cracked ring lands

 

thats what i figured. im not mad about the broken parts, just the break-in period for the forged stuff goin in this month

jack......hey brotha, i need to get a calling card, ill give ya a call tonight. i was rolling with a pretty sick crew this weekend, 3 modded LS-1s, a 700+ hp supra, and the GS-T on 20 psi that beat me up last weekend(i smacked him down friday night though.....he was only on 18psi)

 

That's kewl.....I'll give you an update on the hatch of fury tomorrow night when I get the word from the insurance guy...........

 

dont have manual handy - think its detecting general missfire, makes some sense with the problems you are having, if comp test is good , check, timing belt marks, ingnition and fuel are all working on each cylinder - the missfire is probably detonation on one or more cylinders.
