SLP UD Pulley Inst Question

**89LX** · 06-27-2006, 08:41 AM

I have a new SLP UD Pulley ready to install. The instructions state: "Make sure that the crankshaft is recessed 2.4 to 4.48mm into the balancer bore." Is that to say the crankshaft is recessed into and not sticking (over flush) out of the balancer? Thanks

yeah, thats what it sounds like to me...i didnt get anything like that with my asp. I simply removed the old, installed the new and torqued it down.

That's my take on it also, I'm going with it. Thanks

what kinda hp gains would you get with a pulley?and how much did it cost

I opted for a SLP UD pulley and the cost was $213.00. UD Pulleys actually free-up HP by reducing the amount of parasite drag of the accessories such as the water pump, ac and alternator (depending on the number and type accessory you wish to underdrive). Most people (certainly not all) tend to change out the crank and leave the alternator alone. Generally they advertise 10-15 RWHP gains. Good luck

ok, mine came with the alternator pulley as well. What's the easiest way to get that thing off of there? I'm having the hardest time removing the alt pulley, and didn't know if there is an easier way to do it. Thanks!!
