How much loss with Denny's Driveshaft?
I picked up a used 9" rear that came with a Denny's nitrous ready driveshaft. I hope to have it installed in the next few weeks.
I noticed that the driveshaft is MUCH heavier than the stock aluminum one(duh!) Just wondering if anyone knows how much HP that will suck up.
Thanks!

It's even a lot heavier then my stock steal DS
I really would not worry about it that much. Peace of mind is worth the "maybe" .1 that you would lose from your ET.
You can do a negitive dyno pull to measure the loss of the drivestrain but unless you can do that with the NR and stock shafts it's not going to tell you much

yeah, I would say it's not too much to worry about... when I installed my 231/237 cam, I also installed a Denny's Nitrous Ready driveshaft, a catted y-pipe (was running ORY when in full bolt-on form), and 17" wheels (had 16" wheels before) and still dynoed 46 rwhp more than I did bolt-ons only. No numbers with the F13 cam yet...
I think maybe the Nitrous Ready shaft is worth a 5-10 rwhp loss at the very most depending on what kind of setup you have. Certainly well worth it considering the stock likes to pretzel up on a hard launch.

Yeah, the piece of mind will be nice! I was just curious, thanks for the reply's guys!
BTW, I weighed it last night. With both u-joints and the tranny yoke on it, it weighed 20.5 lbs!
I am getting excited about launching on the juice, w/slicks and 4.33's soon though!

I'd guess at least 8 rwhp over an aluminum. If you get a chance to swap it out during a dyno pull, try it. I'd be curious to know as well. I went from aluminum to a steel speed inc DS
