s1600 Pas pump running off camshaft

[Usr117063]

Just discovered this and wont settle until I have it. Seemingly just a bracket, coupler and a couple of o rings, or is it a different camshaft design? Could this be made from scratch without much effort? (would it cost a reasonable amount for someone to make this)

I wonder why they made this setup and did not use the cup racer setup. Pas cooler line setup in front of the rad too

I would go to an electric pump if I knew 100% they would work like a mechanical. I read that the pump used on some porsche motorsport cars is the same as on some vauxhalls and cheap off ebay.

Would that fit on the K4M or whatever engine these used?

I'm surprised they didn't sack off the hydraulic system and go electric really. One less fluid to worry about.

They had a custom rack and column setup as well.

@bozothenutter What electric pas pump did you fit and is the assistance the same?

Ive found a dacia pump made by renault brand new from a heavier car which Im interested in, Im just worried that there will be a delay with assistance.

I have a Merc A class pump, looking at me accusingly every time I go into the shed.
Have to say that Dacia pump looks smaller though..nice!

Yeah it looks convenient, just want to make sure its going to be 100% before I splash out.

Im sure it will be fine, modern pumps driving heavy cars should be more than up to the job

The merc pumps are spot on, I've driven a VAG track car with a Vito pump and it didn't feel any different to a standard car

Well thats the bit I dont know yet Its a power and earth then theres another connector, Im not sure what has to be done for it. Hooked up to a speed or steering angle sensor maybe.

Ive been having a read and a TRW electric pump from some vauxhalls is exactly the same as used or once used on porsche cup cars, quite a few guys do this conversion from mechanical pump to electrical on their porsches. The nice thing about it is that its a simple power, ground and 12v ignition feed. Also the price is cheap as.

I’d 110% go with the a-class hydroelectric pump.
Easy 2 mount, 2 wires making easy to wire and works great with good feed back.
I’ve fitted one to my mates eg civic with a k20 in and it works well.

there are three wire versions as well, afaik the third wire goes to the alternator as a signal the engine is running I *think*.

BTW there should not be any difference whatsoever, as these are basically just the old pump, but now electrically driven.
So the rack won't know the difference!
Still wondering if it is possible to adjust pump revs (pressure) with voltage to tweak the assistance.

 

[bozothenutter]

interesting PAS fluid cooler btw, don't see any corrugated hose on the Aeroquip site, so assuming it is just a hose?

 

[Usr117063]

I ended up with a TRW vauxhall/porsche one. Ill let you know how it works in a few years.

If my pump gives up I'm just going straight for an MR2 one - loads of wiring info online. I want to keep the A/C so would have to do something about that.

You can get a kit that replaces the pump to keep ac Im sure

Probably - I have (never going to happen) dreams of a Rotrex kit with the shaft running across the front of the engine being driven by a pulley in the PS location, then having a remote electric PS pump...... however I also have dreams about selling the Clio and buying an Aston.... unfortunate I have to say neither are on the reality list for my immediate future.

Cant you sell the other toys for the aston?

The house?

But longer term thats probably the plan, sell sell sell buy something I hate, sell, but another Clio. Repeat until death or insane - standard CS stuff.
