Right guys. I couldn't find a thread for this on here so rather than looking elsewhere I though I'd start a thread here 
Just acquired a TT soarer the other week and I knew it had no power steering due to leaking but only took it along my street and back because I had no insurance. The steering was heavy as expected.
I've had cars with no power steering before but this is just ridiculous. I drove it properly for the first time today and it is genuinely difficult to drive regularly never mind recklessly.
I'm fully aware of the usual fault of the PAS pump but I have read you can modify the steering weight by cutting into wires. There is essentially a 2nd reservoir (I can't remember the name for it) that takes fluid in creating more hydraulic pressure and making steering easier (physics
). You manipulate the wires to the PAS ecu to lessen the amount of fluid going to this chamber meaning the steering weight is heavier/better for track use. Maybe the fact that my fluid is all gone and nothing is getting to this chamber that is why it's so heavy compared to other cars without PAS?
I was going to buy a new pump or seal kit and rebuild my own but I cannot find fluid escaping from the pump so don't know if it is this or a pipe.
The fact that the steering is stupidly heavy even at 70mph has got me wondering if maybe it is something more than the pump/pipe/ '2nd chamber'
Extra info: Car has had the lock modified and is on standard 16" supra wheels (offset +50?) And 25mm spacers. Big brake conversion from a 400 but wheels clear the brakes with no rubbing. No rack mods as far as I can remember
