93 cobra water pump pulley

[88mustng]

i see that it is an underdrive pulley but does anyone know the diameter of this pulley. I wanna see exactly how much smaller it is to decide if its worth it to get one before i go buying a belt. OOh and while i am at it also with the whole belt thing, will a 94-95 mustang gt alternator have the same size pulley on it as my stock 88 mustang alternator. Because my charging sucks real bad esp at night with the lights on and blower motor goin.

I just moved my power steering up to where the ac was so i need a new belt right now, i just wanna get all this out of the way so i only have to buy a belt once.

Thanks,
Steve

Steve,

The alternator pulley is the same size and will work. Just do a search for 3G alternator upgrade or install and you will find lots of information on this upgrade.

As far as the Cobra water pump pulley goes, it is an Overdrive pulley, (making the water pump spin faster), not Underdrive. I have used one before and noticed no difference except that the pulley has no outer lip for the belt. I had mine spit the belt off a few times and ended up returning it. I'm not too sure on the measurement. Maybe someone else can chime in with it.
