Power steering pump belt?

What else is the power steering pump belt connected to?

Can it be taken off periodically to get a bit more power or is that belt necessary to keep there?

The aircon.

I've removed my aircon altogether (as it didn't work anyway and you don't really need it over here

) and replaced my p/s pump with an electric mr2 one,so no more belts and can switch it on and off when i need too....it's worth a couple of tenths.

Was there a noticable performance gain?

Is it safe to take this belt off all together just for say a week or something? As I know power assisted steering racks are different from non power ones and is harmfull for them to be without them.

Is it possible to put an electric power steering pump but still retain air con?

You can drive without the ps without any problems,like i say,it's worth a couple of tenths or so over the qtr mile.

I guess you could run the aircon w/out the ps if you got the correct sized shorter belt...

I would have thought it was invaluable over here ... for demisting the windscreen on frosty/snowy mornings! I've already been using mine heaps for that very purpose

Blowers work well enough!

Mr Bishi can you give me some tips on how to install the electric PS pump?

I talked to my mechanic and he said it is a difficult job as it needs a computer or something to regulate how hard it works? To immitate driving as the engine revs more, so should the pump?

Any info would be great
I want to keep air con though

I've taken it off for that very reason.....as the pump was working on full steam,i've worn out two pumps! (at least i think that was the reason)So i wouldn't bother if i were you.But if you do want to i can give you a few tips.It worked well when it worked!

Yeah some tips would be great

Would it be possible to just get a regulator so that the pump is say at constantly 2000rpm?
As, at 2000rpm I am sure the pump would work well enough for any circumstance

2000rpm? I don't get it.....it's an electric pump,i've no idea what it spins at.

The pump is from an series 2 mr2.The mr2's computer adjust the pump rate according to speed of the car,speed of steering input and i believe it stops altogether when in the straight ahead position. I was thinking of trying to find a way of have it only operational when at speeds of 30mph or under but i don't know how

To fit it to the fto you basically need a pump.....some high pressure hose to connect to the ftos p/s system.A heavy duty relay to control the switching of the high current (and a big ass fuse) then you connect the relay power to the fuel pump,so that the p/s pump only switches on when the car is started.I wired an override switch in too so i could switch it off when i wanted.
I don't have any details of the hydraulic hose/connection sizes as i used a trial and error method using parts sourced from my work.But i'm sure if you took the pump into a hydraulics specialist they'd be able to sort you.

Seems quite simple
Is it possible to retain air con though with that pump?

What I meant by 2000rpm, is, is it possible to immitate the pump working as if the engine is at a constant 2000rpm? That way giving it enough power to easily turn the wheels, and never overload it by making it work on max?

Like you said, your pump had been working like as if the car was at near redline or something, so it got worn out, so is it possible to make the pump work like the engine is only doing 2000rpm?

I guess so.....just by limiting the power to it. I should think that's how the mr2 computer does it.

Not sure about running the aircon though.
