I phoned up Helix asking them what torque their organic clutched would take. He said something like 25% over standard, then asked me what torque I was thinking of running through it. I said between 150-160 lb/ft and he said that would be fine !

Only trouble is they are a few quid !

yes actually, I had a mk3 diesel shaft on mine at the trackday in that picture above. Even though the car is only lowered 60mm the shaft caught on the edge of the sump and even the block, noticed this when I took the engine out recently:

if you can make that picture out, the shiney bits are where the thicker diesel shaft wore the actual engine block!!! Although I'm thinking this wont be a problem with some stiffer suspension. I can only guess it happened during hard cornering on the track day when I was suffering quite a bit of front end roll as can be seen in that picture. The nice stiff coilovers I'm putting on should help that out.

The shorter shaft on a diesel polo is no different from a normal one.

Additionally, the point where the shafts usually break is where the spline end section finishes and on the diesel driveshaft this is no thicker than a normal polo shaft anyway so I think it's debatable if those shafts are actually any stronger.

I only put this diesel one on just before the track day as I got them for next to nothing off a friend who used to have a g40 (Mike King, some people on here will remember him). For years before that I had normal non-g40 shafts with a gemini diff and then my gripper diff and never managed to break a shaft, although I know others certainly have, I guess I've been lucky.

yea i noticed the split bit was the same.

i have broke 3 2 on the join split bit and one on a inner cv joint prob alot to do with the roads where i live though!

I didn't think they did organic ones. Only thought they did uprated with standard material and paddle clutches.

lance · January 30, 2009, 06:44:16 PM

am sure they do organic up to a certain spec

hayesey · February 03, 2009, 10:09:29 AM

hmm get some pics of it up mate, is it just a diesel one or something you've had made?

lance · February 03, 2009, 02:35:39 PM

my mate had it made for me from a standard one.

hayesey · February 03, 2009, 03:13:07 PM

from a standard what? polo one? if so what's uprated about it? or do you mean he copied a normal one, it looks thicker than a standard one.

lance · February 03, 2009, 03:19:39 PM

yea from a standard one no stupid split in it now and its loads thicker.

the guy who made it made this and the shfts for it.

hayesey · February 03, 2009, 03:39:00 PM

ah right so he's made you a new shaft from scratch then? Would he be interested in doing more of them?
