I know some shops that wont even dyno trucks with aluminum d-shafts. They have had too many twist and break at high speeds and it just got too dangerous.

Sucks to hear about it crapping out.

There's got to be more to it than that. The Nissan Titan has an aluminum d-shaft and they're torque monsters and I've never heard of one failing.
Maybe it's due to the truck being lowered, or lifted...(?)

JB1- Nice looking truck.

Its not an NNBS thing.
Concensus was always to Dyno in 2nd. I've seen like 4 or 5 posts since I joined here of people doing a dyno run in 3rd and the drive shaft lets go. Sometimes taking out the trans with it. Usually aluminum or a steel 1 piece.
There have been a few that did it on the highway. Just because you HAVE gone that fast, doesn't mean your driveshaft was enjoying the ride. crawl under it after a run like that and see if there are marks on the driveshaft or bottom of the truck.
That too has been done.

2piece steel ftw!

I'll see if i can find a couple of the threads later.

see my El Camino in my sig it has a inland aluminum driveshaft 5500 stall convertor, T400, with trans brake 16 inch wide slicks 1200 hp on NOS and runs 8's in the quarter....maybe you need a better aluminum driveshaft.....

Did everyone miss out on the 50HP gain so far?

Good luck with it Luis, I bet Xessive puts you at 300hp before your outta there.
