It still has stock shafts in it, but it wouldn't surprise me if it broke one on its next pass.
I have a 5 pinion steel planet, billet steel drum, non LBA Turbo Action transbrake, deep cast aluminum pan, etc. Nothing real fancy.
My car will go 8.60s, but my best 60' is a 1.30 (may not have tripped the beam w/ the front tire?).There's a fine line b/t wheel spin and wheel stand w/ my combo.


That's helpful too, thanks Chip! I'm heavier but am definitely going to be making less power and torque than you.

Do you normally run your car at the track on slicks or the radials?

And one other question, is the LBA stronger for situations like those, or would the sprag have failed anyway even with a LBA valve body?
