Hi Drain the fluid and yes it will still work but will be heavy, I have seen some PAS stripped and converted to manual but i do not think it is a DIY job.

Think you have to also blank it off otherwise it can cause stress to the steering system.Not%100 sure of that but if you do a search there is a lot of info there. Having said that i just dissconeted it on my cab and ran it for best part of a year with no problems.

If this is for a track day or race car, don't bother and leave it in there. It's a good system with plenty of feel (not over-assisted) and will let you be more precise with your steering as well as letting you drive more than 20 minutes at a time without pitting for arm massage :)
All modern racing saloons have PAS; F1 cars have it, too. If you're worried about weight, don't be; it's 5Kg max. You can get an e30 race car under 1000Kg and keep PAS. If you don't want it sapping engine power, an underdrive pulley is a much better bet.

I'm in the early stages of a track car project and I was wondering about the idea of fitting an electric pump from a Merc A class. They seem quite fond of them in PPC. Any thoughts? :?

It seems to be an easy DIY job from speaking to others, I'll grab the how to off SELOC if I can find it

I was lucky I had a munual rack to start with :)

How much power does a pas pump actually take from an engine?

I know an air con pump can take as much as 5 horsepower!

Air con can take more than that...

Why can't you just take the belt off :?

It's Easy to drop the belt but you need to drain the rack take the hoses off, resiovior and pump (remove alt to do pump)

But to make the power rack a manual rack as some e30 m3 racers have down with the z3rack takes a bit of work to rebuid the power rack.

If I was to use the pas rack as a manual rack would the car pass the MOT.

Today I took off my PAS.
Removed pump, belt, resevoir and the double pulley at the front of the crankshaft.
I just joined the two hoses from the rack together leaving a bit of oil in the system.
As far as I can see removal has 3 advantages.
1. You save the weight of the components.
2. Engine power loses are reduced.
3. There is less weight for the engine to accelerate (same advantage as lightening the flywheel).
Only at parking speeds does the steering feel heavier.
At speeds above 5 MPH the steering feels identical to PAS.
With this in mind I am now going to fit a slightly quicker rack (e36).
318 is.

All this nonsence of the non pas rack being overly heavy is bull s£*$, are you men or mice?

As stratos states above once you are doing more than walking speed you will not notice the difference.

However the clear advantage of a pas rack is the availability of using z3 quick racks ,unless you can find a TAS manual quickrack this is the only way to achieve less than 4million turns lock to lock.

I managed to pick up a brand new TAS rack off ebay a while ago,

It was £300 pounds(it seemed expensive at the time) but it will be worth it when my car is finished.
