New Ruslow underdrive pullies
Sorry Stan, I misworded what I wrote. I meant to say most underdrive kits have a SMALLER water pump pulley to speed the water pump back up.
In a typical underdrive kit, for example a 5.0 Mustang, or Gen 1 Lightning kit, you get a smaller crank pulley, a smaller alternator pulley, and a smaller water pump pulley. The smaller crank pulley is the drive pulley, and being smaller is slows down the rpms of everything it's driving. When you slow down the water pump and alternator, you can have cooling and charging issues, so that's why you get the smaller driven pulleys for the pump and alt, to speed them back up. And since you have a smaller crank pulley, even though you've sped the water pump and alternator back up, with the smaller pulleys it takes less load to drive them, so you still gain HP, plus your other power robbing accys like the smog pump and power steering pump are still slowed down.
On Stan's setup, he's eliminated the crank pulley and oversized the waterpump and power steering pulleys. So he's slowing down the water pump and the power steering pump, putting less load on the motor. A little bit different way of doing it, but it keeps the alternator working normal, and we don't have a smog pump on out motors.
I'm already starting to see people getting their panties in a bunch over this, so everyone needs to chill out (except TugBolt since he's a PSP hater and will start crap no matter what). I was just making an observation, and asked a simple question.

Sal said,"On Stan's setup, he's eliminated the crank pulley and oversized the waterpump and power steering pulleys...When you slow down the water pump and alternator, you can have cooling and charging issues, so that's why you get the smaller driven pulleys for the pump and alt, to speed them back up."
I do have some questions about the pulleys. Stan has them on his truck and drives 140 mph plus just like me. Except he does it with his grill covered. How come he has no cooling issues? Second question. Stan likes to go around turns and such which require use of the power steering pump. Why doesn't he have issues with the power steering even though it has an oversize pulley?One more, who said Stan eliminated the crank pulley? How would you go about eliminating the crank pulley? Is that even possible? How would you drive the AC, PSP, WP, and ALT?
Maybe I just answered my own questions...

I'm not sure how long I'll have that picture up so someone may want to make a copy.

Ahh, good ole Easterbunny, back on board with his same old tricks. Guess some things never change.
I never said Stan's pulleys would cause problems, I just made the observation about how his setup worked. He's slowing down the water pump and the power steering pump from stock rpms, in favor of some more HP. I never said that was good nor bad, just made the observastion.
As for your crank pulley comment, that's obviously another one of your stupid sarcastic remarks, maybe one of these days you can try being mature for once.

I read your post, "Sorry Stan, I misworded what I wrote. I meant to say most underdrive kits have a SMALLER water pump pulley to speed the water pump back up.

I'm already starting to see people getting their panties in a bunch over this, so everyone needs to chill out (except TugBolt since he's a PSP hater and will start crap no matter what). I was just making an observation, and asked a simple question." and decided that some of that information could mislead people. Information like, "The smaller crank pulley is the drive pulley, and being smaller is slows down the rpms of everything it's driving. When you slow down the water pump and alternator, you can have cooling and charging issues..." and, "On Stan's setup, he's eliminated the crank pulley..."
So give it a break and find something better to do with your time, I have.

I'LL be in TROUBLE for this one!!
But as some of you know I post to help everyone out not just me.I have run a version of this for the past 6 mos.[and had posted a pic of it to]That is with the p/s pulley but have been running the water pump for over 1 year.The idea is 2 fold one it does slow the items down,to increase LOST HP for the drag of them but also in the case of the water pump it ADDS in cooling and higher RPMs.Think of it this way you are running 3500+ and the coolant is flowing past the cyl wall and such then to the rad to transfer the heat that it picked up.Rite? Now do this little experint[sp][IF you are dum enough to] run your finger thru a candle flame fast,you did not feel any heat or very little rite?Well think of your finger as the coolant,not much transfer of heat?Now run it thru slower quess what you have HEAT transfer!!Same idea.You in reality your motor will get rid of more heat if you slow the pump down more heat out of the motor the cooler it runs at RPMs and the more power you can make.So by slowing down the pump you saved HP from the pump moving coolant to fast[drag] so the engine does not get the transfer of heat out like it needs plus you have better tranfer heat tranfer to the coolant so you can produce more HP with no real ill effects.Hope this helps in explaining why.Stan
