Spitting Driveshafts

I finally broke something!! :eek: after 4 years of slowly working down the 60’, ET and up on the MPH.
Best to date is 11.44@114 with a 10” TA 3500 tight. Best 60’ was a wheels just getting up 1.60. Not content, I finally got around to swapping in a 9-1/2” FTI 4000 hard hit for just a little bit more oomph and first run today with a lame burnout still netted a dead hooking 60’ of 1.54.
Back out for a second run, excellent burnout and it was a “hard hit” alright! Wheels up bigger than ever and “Bang”!! Pooped out the driveshaft. Seems I’ve exceeded the durability of certain factory parts. :eek: Couldn’t help but think of his great tune:



Time to upgrade and re-enforce.
