as title, anyone done it? if so, what parts did you use? and how well does it work?

cheers,
martin.

 

not seen it on a cossie as all the bits are easy to get for normal engine driven pump stuff

but on my brother's mk2 escort it was simply a case of bolting in the motor drive to a section of steering column and using a normal quick rack

what kind are you looking at? an electrically driven hydraulic pump, or the electric column type?

 

question is why? whats to gain?

 

id say either mgf or punto parts would be the best to use. i think the ecu only needs power, alt input, speed pulse and revs. cant see it being that hard to do

 

Main reason why I have done it is to be able to control the amount of power assist, I find that some cars that have fluid power steering have no feel which is annoying but going to a non pas rack then makes it hard work so the EPAS system is ideal.

Obviously when its a old Ford its just about your only option, mercedes do a electric pump that can run your rack but there is no control over anything.

 

For a road car, it's probably not worth bothering about, but

Original rack, 6.5Kg
pump etc >7kg
Original column >7 Kg
Total over 20kg.

special built rack 2.25kg save over 4Kg
No pump Or Belts. save 7kg
GpA or special column, 2Kg. save 5kg.
Electric motor, 4kg. add 4kg

Total weight saved is 12kg

For a race car or track car, thats a lot and getting rid of the belt means more power available.

 

You can swap the fixed-rate pressure valve in the pas pump for one off a V6 24V Granada or Scorpio and utilise the potentiometer that is fitted to the base of the steering column inside on the 24V and convert that way. Gives varying rates of assistance @ differing speeds, plus you can always add an adjuster to override the resistance values for your conditions.
