I have a W reg Tuscan with the common 'fast rack' fitted as standard at the time of manufacture. The issue I’ve had was at North Weald on a track day. When you turn the wheel quickly through a chicane or just left to right after the third action the power steering seems to simply disappear, it becomes very heavy, but returns to normal when driven normally.

Does anyone have any advice on why and what the possible fix might be??

I recall an original road test (by John Barker I think) where he nearly crashed because he lost all power assistance on a quick turn, only for it to come back straight back after. I sometimes get reduced assistance when turning quickly at very low speed as in a multi storey for example so must be engine speed related. Have you checked the fluid level?
May be corrected here but I think later cars had a bigger p/s pump to fix the problem.

Yep, that's the exact same symptoms I have. I'm interested about the 'larger pumps' youve mentioned, if anyone else has more information? I'm lead to believe the pump is off a Land Rover.

.....oh, the system has been flushed and the fluid is the correct level.

Later cars switched to an electric PAS pump from a Saxo IIRC. I've been looking at them as I think my pump is on it's way out. It is the only original steering bit left after all!

I'd speak to one of the specialists, TVR power would be first on my list. They may just suggest fitting a new pump:

I think all S6 cars have the same alternator fitted so, assuming it's working ok, should be fine to swap.

Ye so its just a case of making sure it, and all its connections are sound
,
bearing in mind most Tuscans can't get the power off very quickly,

which reminds me of when we first mapped my LS Tuscan,s ecu
I was at a motor sport workshop having some tuning done, when the guy asked me were the battery switch was
when i replied, it had,nt got one,
he said, you should a battery switch on a car with a bolt on engine cover, its not good practise without

But then it's not even as easy as lifting the engine cover to access the battery anyway, as the fireman found out when my battery shorted and set it's self on fire last year...

And you car,nt put the switch in the car, or boot, because you may not be able to open them if the car shorts in a big way

Walford that is interesting. I've also got a Saxo steering pump that I'm going try to fit(also running V8) but not sure if I have the room to fit it. I was thinking of mounting it on the chassis just above the steering rack.

Was it an easy install?

What engine are you using, and how are the exhaust pipes routed

It's a Ford 302. Currently, running the original Steering pump off a complicated Serpentine belt arrangement on the front which I want to change.

The exhausts just drop down either side of the heads at the back of the engine; a bit like block huggers but equal length. I don't bring them forward.
