Keeping on track ..... anyone any idea how you make sure when using an electric pump that the power steering isn't incredibly light?
I like heavy steering, means I can 'feel' the road. I just worry if you fit random bits together you may get too much assistance.

That could indeed be a problem. I think I will just have to experiment, hopefully by choosing bits from similar cars I might get lucky. It would be
good if it were possible to control the amount of assistance in some way, but I'm not really expecting to get that lucky

You may not like what Mikerj has to say, but he is correct that de-powering a power rack is not a good idea. The torsion shaft is a skinny little
spring that is designed to twist allowing the spool to work smoothly. It is also used as an emergency manual connection.
It is in no way designed for the extra load of constant manual operation. Torsion shafts are usually all of 0.25" thick VS the 0.75-1"
tube that is normally used for steering shafts.
You will also get slop because the torsion shaft will flex before turning the wheel as it is designed to.
Custom racks really aren't all that much money and you will get a faster ratio so you aren't flapping your arms like an idiot while
racing.
Cheers.

Au contraire, I am happy to read and take in what Mikerj has to say, if I showed any annoyance it was his crack about the "dozens of times
before" that I felt I had to reply to, not the mention of the torsion spring.
In any case, I have already said, based on the information received in this useful thread, that I will be using an electrically powered pump so the
issue of using a power rack without the power will not arise.

Just one other alternative for you. On the works 6R4 we ran a standard PAS pump off the front diff driven with a poly-V belt. Worked well (except for
parking  ) and, as far as I am aware, passed MOTs.
