Will my drivetrain blow?
I have a 99 vette with the following mods:
Vararam, catback, LS7 clutch, hardened output shaft and an ECS brace.
How dangerous would it be to run it at the track with drag radials? I would be launching it at about 2500 rpm, but would be shifting aggressively through the rest of the gears. Assuming I avoid wheel hop, how close would I be to blowing anything on the drivetrain?
Also, what ET could I expect if I run it with the radials?

The rear-end is the weakest link. You would most likely (but not 100% going to) break an output shaft.
Your tires are the FUSE at the track. If you put a bigger better fuse in the tire slot,, the differential output shaft FUSE will blow! ANY excessive wheel hop will cause that fuse to blow!
Wheel hop is the enemy of drive train reliability! PERIOD!
I have run my 02 ZO6 at the track with out any issues, I run it hard on the street with out drive train issues. I DO prevent wheel hop by tires, launch technique, shocks and care.
NO Issues!

I did change the weaker of the two output shaft (forgot if it was the left or right). So as long as I manage my wheel hop I should be good to go. I'm a former F-body guy, and their drivetrains were terrible from beginning to end. It's hard for me to believe that swapping out a few parts on a vette will do the trick.

AH, grasshopper,,,, You have very good observation skills.
When I up-graded the rearend with C6 ZO6 parts I found that the bellview spring on that side was broken. That will cause the clutchs on that side to catch and release and make those marks. If you look hard , you will see the mark on the right starts to fade a few feet before the one on the left. The clutches were most likely SMOKING HOT!
Heres a picture of the broken spring:
BAD BAD BAD!!!!!

If you have already installed a hardened output shaft, keep the wheel hop out of the launch and you should be good to go.
