Default Underdrive Pulleys

What underdrive pulleys are you running? I'm looking to buy a set soon and I was curious as to what brands people have had the best luck with.

I'm currently running a asp pulley, the dam thing kept on running off. If i were to do it again, i would do the slp. It has a higher lip, correct me if i'm wrong...

this may be a dumb question.. but whats the advantage of an UD pulley? does it put less strain on the motor or what?

I think i'm gonna go with the SLP. it has taller sides, less chance of a thrown belt.

Since I don't feel like typing much, basically it free's up some power. Less strain as you put it is a nice way of describing it. I picked up 8 rwhp and 12 ftlbs on G-Force's dyno when I had mine done. Well worth the money to me.

no prob getting the old one off, just need a 3 jaw puller. its getting the new one on that sucked. they suggest that you throw it in the oven for a while to get the metal to expand, which is supposed to make it easier to slip over the crank snout. mine just wouldn't cooperate, and i had to bang on it for a while before it would go over the snout. and of course the radiator is in the way, preventing you from getting a good swing at it.

once you get it on enough to get the bolt threaded a bit, you just pull it on with the bolt, which isnt bad... until you gotta torque it down to 250ft-lbs.
