That probably played a big factor in why it let go. Stock cats and 17psi probably was causing boost stack and really high EGT's.

Either that or running 100 quarter mile passes on the stock bottom end.

About 180 trips on the bottom end but only 150 or so under boost with the 2300, obviously some were 1/8 mile, but only about 1/3 I would guess. Yep those big old cats hanging down there plus it did have 12,500 miles on it. That why I said we flogged the F out of it from 900 miles NA I think I put the blower on with about 5000 miles, don't think I wrote the mileage down. I think I have about 60 passes on this motor and about 1/2 were with the 2300 since we didn't put the 2650 till just before Camaro fest.
