I have underdrive pullies on my 99 gt 4.6L sohc engine. I'm about to put a supercharger on it. is it gonna hurt anything to just put back the stock crankshaft pully on and leave the other two alone?

I do believe if you use a SC you need to replace all the stock pullies. The good news is you get some cash back when you sell them for more mods.

you need to replace all the pulleys. if you left the alt and water pump on i bet the belt will slip like heck.
