did you even read the post above let alone what this thread is about?

no thats why i asked

Where's the 'facepalm' smiley when you need one

3. I have not inspected a LHD rack but i imagine it is a mirror image so 99.9% yes.

True but your need to run the rack and pinon upside down for a RHD car so i very much doubt you could get a 034 or a selholm to work

im in please if a 1986 coupe quattro rack can be made as quick as possible? (for competition)

You can have a 2.1 rack the same as mine if you like. That will fit a S2 one will not

Alex has done a out standing job on this and i am shocked more people have not jumped onboard

Yes this is true, what i meant was that the pinion will likely be near identical so the T-bar should be the same

Alex i have those photos's you asked for.... And i took them against a S2 rack

Hi guys,

No TBH I didn't do anything yet due to lack of interest and I don't want to waste their time as they are very busy.
My adjustable PAS pump prototype is almost ready though.

Rok:

1. Yes you would supply a rack, s2 or B4 are OK the T-bar is the same.
2. Yes it is possible but you can already just buy a stock ABY/ADU rack which is 2.6 turns, or for a quicker rack 034 sell a 2.2 turn rack, Selholm do one too so there is no market for it.
3. I have not inspected a LHD rack but i imagine it is a mirror image so 99.9% yes.

hey error,

cool, thanks for the reply. so, the PAS pump modification will produce similar results to the rack mod?

i just found out that the UrS rack ratio is 18.89:1. oh dear...

Hi Peter,

Similar yes, with the adjustable PAS pump you will be able to reduce the strength of the power assistance somewhat and increase feedback (the self centering effect). Unlike the stiffer Tbar you won't gain any steering "feel" though.

I am also working on another little mod which I hope will make an improvement to the steering feel :mischeif:

oh yeah???

... all in good time
Theory only at this stage, need to make a prototype to test, but it won't be an expensive part.

..On my URS6 (trackcar.. work in progress) I was hoping to be able to reduce the ratio to get a more direct feel, and then remove all the servo pump and actuator and replace the whole lot with an electromechanical one..
Pros: reduce power wasted on "useless" hydro pump..
Cons: probably the cost..

I'm doing this in my free time (mostly at night!) so it might be a while before I sort it all out.. but I'll keep you informed!

Any updates regarding GB shipping to Canadian/US customers?

[Error404]

I won't be doing a GB at this time due to lack of genuine interest (pretty common on this forum TBH)

[petro238]

..I am making a little progress:
Found a company in norhern Italy and apparently they can reduce di some 30% the lock to lock travel on my rack..
it might take them a month or so..
..€ is another issue I cannot talk about for the time being..
