underdrive pulleys

[94 DropTop]

Well to get my car back up and running I had to put on my factory water pump pulley but am still running my underdrive crank pulley which is smaller than the stock one. Is this ok or do i need to go back to my factory crank pulley?

Some guy's I know around here have told me that on hot climates it's best to just put the crank underdrive pulley, since it will only slow down the A/C and the P/S and NOT the water pump & alternator. So it makes some sense to me imo.

Given that the crank pulley is what drives everything else, EVERYTHING will turn slower with an underdrive crank pulley.

ok thanks guys. Ill leave it for now. I dont want to deal with finding a belt again. I figured with a smaller crank pulley on everything would turn faster......owell ill get it taken care of later thanks paul for correcting me.
