which u/d pulleys Ima do a cam swap soon Got all my parts oordered. Tsp torquer v2 cam 113lsa, hooker long tubes, tsp ory, slp loudmouth2, yank ss 3600, 80 mm throttle body. Since the pulleys are coming off i wanna get some underdrive pulleys should i get crank and alternator at 25% u/d
lots of threads on the subject , plenty of posters say the expensive ati is the only way to go. i like slp parts but i chose the lowest cost 25% ud pulley. after 2.5 months i had alternator trouble so i would recommend an overdrive alternator pulley. cheers!
No need for a OD alt pulley, just bump up the idle speed to offset 25% slower rotate speed IF you have alternator charging/output issues. IMO, the best reason to go with a aftermarket Crank pulley is for it's better harmonic dampening ability. So in that regard I recommend going with either a Fluidampr, or ATI, or just staying with the factory crank pulley unless it needs to be replaced .
I run an ASP UD pulley... Had it on over a year now with no isses. I do recommend a alternator pulley also.
only because the voltage drops Little lower but it hasn't effected the cars performance or charging issues.

I definetly wanna do a crank pulley. I dont plan on running a high powered stereo at all i just wanna squeeze out all the power i can with bolt ons. I know different brands have high retaining walls for less belt slippage is slp one of those brands?

Powerbond and SLP are the same pulley (made byPowerbond and reboxed by SLP). I have a Powerbond on mine. With the cam it's going to bump up your idle anyway, so you should't have any issues with the alternator.
