944 axle/cv upgrade

I measured my 85.5 passenger side axle at @ 21.25" and the shaft diameter is 27mm. I read that 930 axle shafts are 26mm diameter but I am trying to find out if the 944 axles can be resplined to fit 930 CV joints? anybody Know?

Not sure it would be hard to respline them unless they were welded up and remachined. I've always wondered if there was a better axle setup out there. That was what usually broke back in my drag racing-street racing days on my car. It's similar to a lot of VW's etc and there are plenty of them making big power granted they weigh less.

You should be able to have the 27mm shaft resplined down to 26mm. This is a common practice for the off road world, where people change axle lengths regularly.
Here's one of many places: http://www.currieenterprises.com/htm...ndservices.htm
What surprises me is that the 930, an air cooled 911 turbo making 330hp, has smaller diameter axle shafts. Yet I've heard the CV holds up to more power.
I wonder if the smaller diameter axle is helping keep the CV alive, due to absorbing more of a shock load.

Probably a more expensive alloy

I was hoping someone here had a definitive answer about the CV spline diameter of the 944 and 930. I know that the 944 has 33 splines and the 930 has 28, but that does not necessarily mean that the 944 axle CV splines are larger in Dia.
If you look at a 944 axle, the shaft diameter (27mm) is actually smaller than it's CV spline input diameter.
I just want to know what the 930 shafts look like so I can know where to proceed with the 930 CV upgrade since it is a brute and has more articulation degrees than the 944 CV as well.
