the car needs a power assist rack,
the rest of the steering system isnt designed for operating with out it.
I could see the steering coupler easily shearing off then you will have to be replacing column parts

 

My brother's 83 944 had a manual rack. I'd be curious to compare that set up to the 928. Porsche is a small company, and I'd bet a lot of those parts are interchangable.

 

the other parts that will suffer from the strain will be the upper shaft bearing these are made of brittle metal and they will crumble, this can then damage the turn signal switch housing and the trim collar around the pod
Beyond that the car will not be as nimble as it should be thus handling will suffer

 

What compounds the problem is a power steering rack is typically "faster" than the same vehicles manual steering rack.
This makes the effort required on a power steering rack w/o the power higher than a manual steering rack. That being said I converted a power steering rack on a 944 Turbo S I had to manual steering. I removed the power steering lines and filled the required areas with grease. Once changed the effort wasn't all that bad. But I would make a concerted effort to have the car moving before I had to make significant changes to the direction of the car.

 

I agree; a "sealed" power rack without a pump assist is much harder to steer than a true manual rack. It's like driving a turbocharged car without the turbo. It will still go, but it will be slower than the naturally aspirated version of the same car (for several reasons).

What I'm suggesting is somehow coming up with a true manual rack, one that was designed to be operated as a manual, for the 928. What Stan is saying is that this is a very bad idea! And I did not stay at a Holiday Inn Express last night. So that's that. My original point was that Porsche, had it built an RS 928, would likely have made the rack a manual one, given that it did so on past RS 911s. Plus it's a weight savings, and a mechanical savings for the engine. One less pump for the engine to drive with a belt.

 

Mike I have been thinking about that for months as i only have 2 accessory belts (3 less, have electric cooling fan) at the moment and I wanted only an alternator belt if possible.

I really want to explore that and you have beaten me to it, guess we think alike. Stan you could help figure this out. Lots of old race cars were hard to steer until they got rolling.

Anywho, it's like deja zu all over again. Car and panels not polished, don't really need it. Finally ready to assemble things. Motor home is stuffed with 928 parts, very cheerful in there.

Ready for panel fitment; doors have to be first (marked there hinge attach locations with a scribe), then front fenders and hood. Waiting on proper fender- body adhesive. Hatch can go in anytime. Very excited. Wheels are OK for a 1983 RS Concept i guess.
They will be replaced or the deep 951 Phone Dial dishes will be painted silver. They need something, kind of lost in space.

My little Buddy up on the left, thinks the RS "resembles the Bat Car" right now.

 

Fred I'd like to try this, keep ideas coming.-Matt

 

They lost because the car is missing all it's black trim, which would offset their obliqueness.

 

Yes, you are right Jim.

I would like the dark factory finish which looks to have been anodized, as seen on Neil's '81. Those have a subtle brushed look I like a lot.

And obviously your wheel design would be my first choice.

Here's 1.5 hours i'll never get back.

 

The first part to fail will be the rubber coupler on the steering shaft. I've been running without PS for a few years and had to replace it as the strain was way more than it was designed for and the part was old to start with. Have a look at your coupler, if there are any cracks, it will not hold up for very long.

 

Thanks, will do if I decide to try this. I will leave it alone for now. Just want to get her road ready right now.

IMO00, by chance any idea how much weight reduction the pump removal would be?

Also you didn't say whether this modification is easy to live with.

 

Can anyone post a pic of the exact location of the tire pressure decal. I took a pic but cannot find that one.

Also are they available new ? Tire pressure sticker got bent trying to remove and save.

I want to re apply the under hood decal and the rest. Can't do the VIN of course..

Be really cool to apply a Gulf Blue paint code sticker..will have that made.

The factory stickers are available for 356s and 911s.

Any help is appreciated.-Matt

 

Hatch on.

 

My pump is still on the car, it was leaking so I just cut the belt. Haven't got around fixing it yet. Very slow speed turns are a pain and have to think ahead. Once the car is in motion, can't tell the pump isn't working.

 

Hi Matt,
Car looks beautiful. How much interior are you going to put back in? You could paint the interior sheet metal gulf blue and leave it bare.
Keep up the great work,
Dave
