Mythbuster: continuing project thread of my 1303 '75

Here is a link the the GKN catalog. http://www.rowland2.com/pdfs/cvdisc.pdf

I believe 930's are size 15 CV's and 934 are size 21. They have both plunging and fixed in this catalog.

Interesting! I see that T2 CV's are type 13 there and 100mm (99,7) OD.
930 is then type 15 with 108mm
934 would be type 21 and is 128mm (!)

The weight difference:
T2 : 1,4 kg
930: 1,8 kg
934: 3 kg (!!)

If I can keep the T2 CV's in one piece (and assuming we use type 174 in that catalog), that alone saves me almost 0,5 kg unsprung weight per wheel and almost 2kg total weight for the 4 of them.
Not to mention what you would drag along with 934 CV's...

These things add up fast.

I missed the details Wally. How are you running 930 and T2 on the same axle? The splines are different. I inquired years ago to Sway A Way if they would build me a set like that and they said no way.

I don't.. I run the front 964 flanges which have 100mm CV size and fit the G50 as a glove. So I still run 100mm on both sides, just with the simple VW spline.
The axles and CV's are still exactly the same as I ran them on the 915

Engine finally in after I was able to lend a 930/G50 shaft to align the dual plates..

FYI, type 1, 915 and 930/G50 splines next to each other...Guess which is strongest

Hi Wally,
You know what, I wish I had gone for the G50 box way back when the chassis was being done. We will wait and see. It is a hell of a lot of work to get everything out if I break something. I have got some real tasty pictures from John Maher of my engine but can't get them to upload onto the site. Any ideas?
