For those running underdrive pulleys I was wondering what the key differences in installing a complete set vs. just the crank pulley are. Will a complete set drain the battery, or affect the water pump/cooling system? Is there enough of an hp increase to justify the extra $$? I have a 91 Sentra SER with i/h and also looking for the right exhaust.

Supposedly, the stock pulley for the water pump drives the pump too fast at high rpm and will actually impair the cooling system. If you plan to run your car at high rpm for extended periods of time it might help to have the water pump pulley. This is all hearsay, I do not necessarily believe it or think it is necessary. You will gain HP from this mod though.

the crank and water pump pulleys are the ones that give you dyno proven hp. the other 2 didn't do any thing on the dyno. I trust ben from JW technologies he's very honest and not out to rape you.could have sold me the other 2 easy but told te truth .any way the pulleys felt great.

How much does a set of pulleys go for, and do I have to get a smaller belt to run these(since the pulleys are smaller)?

$170-$220 depending who you get them from.

I did the crank and water pump on my car. I reused the 4-rib belt and had to get a smaller 6-rib belt.

ya, the p/s and the alternator pully only got 1 hp on the dyno. worth the extra money? maybe on a real race car.

D'OH!!
I meant to say that I reused the 6-rib belt and had to get a smaller 4-rib belt.
