Stock propshaft strength
Discussion
I don’t think Monkfish ever recommend anybody needed to change a propshaft for a road car even with 600HP.
Obviously you would have to keep checking the centre bearing and the two rubber couplings at either end just in case
I would pm Wormus on this forum, I think he’s pushing 800HP+, he will have a ton of knowledge to share.
He’s also got one of the best high powered Monaro’s in the Uk.

I have a carbon fibre one peice from the DSS, it didn't vibrate at 150mph but I've only tested that once.
Sat on the dyno near the top of 4th it felt like it might have been vibrating a little bit, but I haven't sat in a car on a dyno before to know to be honest, I shall investigate in future once it's back on the road and in Mexico

Most kind of you to say so. Yes I still use the original prop with no issues at all. Driveshafts are a bigger problem, try to get some that use Porsche cv joints. Top Cats made mine.Obviously you would have to keep checking the centre bearing and the two rubber couplings at either end just in case

I think I will take my chances with the stock prop with new bearing and doughnuts, I will probably be traction limited anyway. I really don't want a single piece due to potential vibration issues. The DSS sell a 2 piece but it's over £1500 once in the uk.
Just get one made locally ?I got my shaft from IEDLS in the US...it was expensive.
Before that I had Carolina Driveline make me a 2 piece shaft, just a little smaller at the CB section than the IEDLS one, but it was very very reasonably priced.
In general, a simple steel 3" shaft with 1350 joints shouldn't be too expensive. Although a lot of the 2 piece tend to use generic centre bearings, as opposed to what might actually fit your car without any work.
I would assume the only slightly awkward part would be whatever flange is on the diff but I'm sure there are options for that
But locally, I had Dave Mac balance mine just a few weeks ago, they seemed decent. I'm sure they could make you a 2 piece.

Nice Paul, any drivetrain failures?
No, standard CV8 diff too, albeit with Harrop cover, Gforce drive shaft CV joints gave up early on, hence using Porsche 930 ones now. Drivetrain is pretty strong and of course, once you get beyond a certain power, it just spins the wheels.Gassing Station | HSV & Monaro | Top of Page | What's New | My Stuff
