I have the 3-piece set of Saleen underdrive pullies sitting in my room that are brand new, but now considering a different route. Thinking about selling them, and purchasing the Steeda underdrive crank pully and a back-up crank bolt from Brenspeed for 180$. Also will buy a Meziere´s electric waterpump, the relay kit, and a new shorter belt. Would this be the best route for hp gain, as far as the serpentine system goes?

Current go fast goodies are C&L Racer, 93 Brenspeed tune, Shaftmaster 3.5¨ AL/DS, and BMR rear lower control arms.

I had the Meziere EWP first then added the Steeda UDP's. It is a good combination. The EWP allows me to cool my car quicker at the track or Dyno. You need a 99" belt, but you can get the belt for CHEAP on eBay.

I got the stock WP pulley replacement from Steeda and keep it with the longer belt, and stock WP just in case.

The UDP's should be good foe about 4-5 RWHP free-up. I believe the electric water pump is about the asme but someone posted that a dyno showed about 18 RWHP. I don't believe it, to be honest.

An aluminum DS will also free-up 3-5. You might also want to consider a few weight loss mods.

I should be able to get the replacement belt for next to nothing, or possibly free, since I work at a family owned shop.

Yes, his dyno showed 288hp/304tq with only EWP and axle-backs. Interesting indeed. All the websites show 11ish hp. Either way, it seems the best upgrade for this area. Little by little, you know.

Weight loss wise, I´ve replaced the DS (20.3lbs), rear lower control arms (6lbs), stock air intake (4lbs, guessing), and spare tire and associated items (35lbs, right?). That´s about 65lbs....

I say that is a good next step. You can get an ARP crank bolt, they are reuseable.
