So these will bolt up on a Sierra?

How will they go for rim clearance?

[bigrig91]

Hey mate, what would the road behaviour of these be like. Also, rally style off road racing events? I know nothing about these or the way they drive but it seems like they wouldnt be very smooth? Would they handle 4wd high racing?

out of curiosity, why choose chain over cogs? im assuming its a cost thing in that chain us easily sourced and doesnt require machine time or hardening?

[DarkHorse]

I missed this earlier, but on re-reading:

Are you back to an off the shelf CV for these instead of the uni-jointed drive-shafts?

Trying to keep track of the componentry (for a 1.6 Vit, staying IFS):
- Diff = either GV steely or your custom steely? 26 spline side-gears only?
- Axels = stock + stub + adaptors, or your customs?
- CVs = something mysterious off the shelf or custom uni shafts?
===PORTALS=== (incorporating strut, tie-rod, balljoint and caliper mounts?)
- F.W. Hubs = standards?

So looking at that it's very much a discreet system, we can't pick bits and pieces to suit?
(eg - I'm unlikely to be able to afford the portals, but I'd love a stronger CV option.)

All very cool regardless

Vitaras struggle to fit bigger than a 31 in their wheel arch. 33's fit with some guard and firewall chopping, but how will the extra 90mm track width effect guard and firewall clearance with such a dramatic increase in scrub radius?

I don't like the idea of using straight cut gears. The gears for the chain will have to be machines and hardened anyway. Plus I can save a lot of room by going to chain.

This will be an option but not required.

If you wanted to ugrade the front diff yes. But not rquired.

The outer CV will be changed for a new shorter version (splines) and then the portal bolts on.

Unless you go my solid shafts you only replace outer CV with an off the shelf item as above.

Struts do not change or move, tie rods do not move, brakes moved down with stub axle.

I'm mainly doing the tailshaft front for vehicles without portals. I'm not getting ahead of myself here as it's only in the planning stage.


Scrub radius etc I'm not sure about yet but the model has been changed to suit the Ramsey silent chain system.

New height increase........67mm....was 83mm.

New track increase......52mm (each side)....was 86mm.

Gearing still at 1.3:1

[Fatzook]

Well 52mm track increase has brought it back within the realm of big offset wheels, which people have been living with for ages, so that sounds promising.

[got_bar_work]

Just depends on wat the rim size and offset has to be to clear the portal
If u could clear it with 16 x7 10p u should be right more then that and they are going to be way out there

[DarkHorse]

Thanks for the answers JB.

Will definitely be up for a pair of shafts (plus spare) when they are done.
Otherwise looking forward to progress.

[joeblow]

New style smaller box. Just waiting on some chain CAD to come through.

[atari4x4]

something like these could bring the sparkle back on the old silver princess.

[JACKAL]

this wont make the front of a vitara flex any better tho. just give it a big lift and clearance

[atari4x4]

helloo captain obvious

[twitchy]

Possible to portal the later GVs Joe????????????????????

[troopy]

These look like a 2 gear design portal so I was wondering how you planned to reverse the direction of drive at the wheel

Plan changed to a chain drive,
so direction stays same with 2 gears/pulleys.
Thats how I understand it?

[sierrajim]

Personally, I'd be looking at the twin chain. The additional width could possibly add a little too much load on ball joints however the added security of the load sharing would be an advantage.

was the point for SAS not to make the front flex better?

No. Portals gives you better groud clearance under diffs.

Suspension type and geometry affects flex.

EDIT: oops misread that,

[got_bar_work]

The point of the sas was to get stronger cvs not big ramp flex
The portal will offer stronger axels and cv and gear reduction for larger rubber
If the strut can handel it
And if u can get a small enough rim to fit then this is going to be great
Ps if this fits a vit then it might fit a coily to as they run the same hubs

[DarkHorse]

... and we're not talking about SAS anymore...

This question /\

[joeblow]

The plan is to flow on to other vehicles. Just waiting on some gear to come from the U.S.

[got_bar_work]

Any idea of rim size and offset needed to clear these

After today I will be waiting with baited breath, so gotta stop it scratchin it's belly!!!!!!

The plan is to have any wheel fit it, from standard offset to aftermarket.

I looked at a cnc machining centre today that would make these easy......the wife even said yes ..........I'm running out of real estate though!

i wonder how many hours you'll spend cooped up in the shed then!? haha

[atari4x4]

move the wife & kids into the shed & take over the house?
