I have the raby underdrive. It is the smallest pulley made that still allows you to drive the car daily.

i am assuming you ment to say - put an underdrive and a small pulley for the power steering?

I think that this would be too much. one or the other.

if i am at idle, my alt puts out 12.9-13.0 volts. my power steering works great, but i can tell any less pressure would be too little.

Also if i turn all electrical things on the car, the lights, ac radio, radar dectector, sat reciever, heated seats....eveything... my output at idle reads 11.9-12 volts.

so you can see any slower would not let the car recharge the battery.

Also the advantage of the underdrive over the steering pulley is that it slows the steering pump, and it lowers rotational mass of the crank at the same time. increasing torque and a little HP. just a steering pulley should not do that.

i recommend the raby pulley 110%, for around 300$ and a little work, it is the best bang for the buck hands down.

DONT FORGET THE NEW BOLT AND WASHER!!! dont cut corners or you risk sittng on the side of the road.
