    i just replaced the p/s pump on my '89 suburban and it is fine as long as i dont turn the wheel very fast. it seems as if it doesn't flow the fluid fast enough to accomidate quick mauevers. i think by gettin a smaller pulley it will make it pump faster and therefore flow more fluid. am i right, can i get a smaller pulley, will this hurt the pump?

    Is your belt tight? You might need a new pump. Your stock pump should be sufficient. My friend has a K20 Sub with 44s on the stock power steering, and it does just fine.

    FWIW, they made different "valves" for the PS pumps. Since you just replaced yours, I'm assuming it wasn't from GM? Did you compare PS pulley diameter before you got rid of teh old one? Mine doesn't give much assist at idle, but thats because its off a car : )
