Mustang power rack

I am using a pinto suspension, a chevy power steering pump, and a 94 Mustang steering rack. I wanted to know if I need to use a volume reducer in the newer mustang rack?

I've read post saying that you need to use one on mustang 2 rack but nothing on newer racks.

The reason for using the 94 rack is because it was free and it was wider so I didn't need to expend it to work. Just need to know I need a volume reducer?

Thanks

Yes, you will need to reduce the pressure. Free isn't always a good thing, if the geometry isn't right your safety will be compromised.

The rack works perfectly in the truck just needed to know if I need to reduce the pressure before I do any damage to the seals. I'm always concerned with safety the main reason for using it is because its the perfect size.

well, is he trying to reduce pressure OR volume?

my GUESS would be pressure but i could be wrong

if it's pressure, don't get to excited, i've ran my MII rack (used) for many miles with a run-of-the-mill gm (not for r&p) pump.

if you're REALLY worried, grap a pump off an early omni (remember those POS?) or a mopar FWD wih a saginaw pump and use it....


some of you guys really make stuff complicated....

After rereading the original post I see he refers to volumn. I'm pretty sure he means pressure as the gm pump puts out I think over 1000 lbs. pressure and the MII rack needs less around 8-900 lbs . Don't qoute me on exact #'s. A search on this forum will turn up a lot of info as this has been discussed many times.

Typically to be very effective you need to reduce volume and pressure. I use the P/S valve for the same pump from a 4 cylinder car, it has a small orifice. Then adjust the shim pack to reduce spring pressure. That is the inexpensive way to go.

Flow Control valve needed

What is needed to connect a GM p/s pump, rated at 3gpm, to a Mustang II rack, using 2 gpm, is a flow control valve. Speedway Motors has them, under $20, when I bought mine. It screws into the back of the p/s pump, replacing the control valve already in use. I have a the same set up and it cured my problem. Problem known as the "twitch" commonly caused by mating a GM pump to a Ford rack.
