I'll have to soon rebuild my power steering Griffith box, alternatively I was thinking to swap in a non-power sistem, is this one more accurate in sharp bends? How much lighter? Should I swap in a full sistem or can I rebuilt mine without the pump?

Thanks

I've had both and in my view it's a no brainer - the PAS rack is faster so corrections are quicker and easier to make and to my fingers at least, doesn't lose any of the feel.

What about weight savings?

That's a fair question but the majority of Griff 500s generally have more power than handling and as I prefer the steering of the PAS version I guess it gives me a bigger bonus than a couple of kg weight saving would.

In most of things I work to the KISS principle.

The Griff really doesn't need power steering, not that I've driven one which has mind you.
You do have to think about where you park, because tight spaces are a pig without PAS. I don't choose to park in tight spaces, but numpties do seem to take pleasure in making it so when I get back.

On the road above 5mph and the non PAS steering is light and responsive. Bordering on the scary at first, if you try to grapple with the car rather than guide it.
With the non PAS Griffith I like the analogy of it being a horse, you point it where you want to go, let it do its thing until you get there, then point it again, no need to dictate what to do all the time. Otherwise you'll have white knuckles, an aching jaw and a worn out sphincter in no time.

It would be interesting to drive a PAS car and feel how much of that 'feedback' is lost.

With non PAS you will miss those charming little puddles of red fluid on your garage floor.

And plumes of smoke coming off the lower exhaust when it burns off a few drips!

I guess I must be lucky, I fitted my rack 4 yrs ago and have never had a leak or problem with it since.

Neather did I...and my rack is 13 years old, never an iussue until a couple of months ago.

I've driven both and PAS is essential IMHO. Yes there is a massive difference in effort needed to turn at slow speeds which makes things easier with PAS, but its the directness of the PAS that makes the real difference.

I think the 'pro-PAS' lobby would say that the faster rack makes it easier to apply rapid steering corrections and the lighter steering reduces fatigue. The 'anti-PAS' lobby would say that unassisted steering provides better feedback and that the steering isn't heavy enough (when you are driving hard) to require assistance.

My V8S doesn't have PAS. The steering is a bit heavier than ideal on the road (I do run slightly wider tyres than normal and with quite a lot of camber) but not heavy enough to be an issue. On the track it gets lighter the harder it is pushed, and on the limit in the wet it's finger tip light. I wouldn't want PAS on this.

On the other hand the Topcats race tuscan on slicks without PAS was so heavy that when it was loaded up in corners I needed both hands on the wheel just to hold it - there were several places at Silverstone where I really wanted to change gear but literally couldn't take a hand off the wheel to do it. That's a car that really needed PAS.

Disagree.. feed back is near identical, dare I say better

I had a non pas 4.3 for 6 years...

put it in a ditch once, the steering can get very heavy correcting things

Then did a mira wetter the better course with my new griff 500 with pas

Griff 500 with pas is 2.2 turns vs 2.7 turns lock to lock.
It is much easier to catch/control the back end...
Below 2-3 miles an hour you can actually park/manoevure, etc.
Above 5 mph, i can honestly say it feels no different to a non-pas car.

Pas is there if you need it. Most tuscan challenge (which the griff is based on) cars had pas, at least the ones at the front did!

My car was originally specified with PAS as a demonstrator and company car for the dealer principle to Nigel Mansell TVR.

I would assume that as dealer principle, he had driven cars both with and without PAS before choosing PAS.

I would also assume that he knew more about testing cars than most people.

Obviously the PAS will sometimes require more maintenance.
