Racing a '75 Granada pure stock with manual steering now. I have the parts for power assist steering and have heard some concerns about it's durability. Does anyone have experience using this on dirt? Any help or suggestions would be welcome, my arms are tired.

Not sure about the durability of Ford's PS, but we've run PS on both of our 80's Monte's going on the 3rd season now. The one car has a Jones Racing serpentine belt setup with their racing pump, the other car has a factory V-belt setup and factory pump.

The serpentine car is smooth steering and that pump has no problem whatsoever spinning at 90% engine speed. The factory setup car eats pumps about every 20 races. Basically the best we could do pulley wise was 110% on the PS pump. So at 6500ish motor rpm, the PS pump is spinning around 7200rpm. Compare that to the 5800rpm the racing pump is spinning. So it's no wonder the steering is a little glitchie at slow speeds and the pumps don't live long.

Try and get the biggest pump pulley you can fit. Old/used/20 year old stock pumps won't like to spin fast for very long.

i used to race granada's. i was scared of the power assist. one good lick and the ball socket can come out and you have no steering and the power assist slave cylinder is right square in the way of the headers.

i had one granada that i swapped pinto spindles onto and used a mustang gt rack. it worked out nice but you have to be careful when fabricating the rack mounts not to mess up the bump steer.

Outlaw,if it's similar somewhat to a latemodel type servo-slave wouldn't that type stuff interchange and make it more durable?

you could probably fab up something, but it's still in the way of the headers unless you use a set of crossover or 180's. it's a rear steer car.

Assuming the Ford steering you use is similar to ours, the only probs we had were a lack of steering feel and exessive pump speed at big revs. The pump speed caused the resivoir cap to blow off and throw belts off. We just went to a smaller crank pully and cured both. The lack of feel can only be fixed by running heaps of castor (not always a good thing) or by converting power steer to manual.
Hope you get your car to work, more racing Fords is never a bad thing!
