I didnt know SLP made UD pullies but I came acrossed these and in my own opinion i think SLP is best for my stang but are these as good as the Steeda UD pulley set?? are these the dreaded piggy back ones or not? I like SLP and STEEDA so either one...which one would you pick??

http://www.lmperformance.com/4327/50.html the slp UD pullies are on there.

 

anyone??

 

no idea but i got a set of U/D pulleys to sell to you

 

Id find out if they are a piggyback setup first.

 

I have BBk on mine and never had a problem..some people say they don't like them..

nothing SLP makes will dissapoint you. i have the steeda underdirves but both are ok. if they are the same i would get the steedas just cuz they are known to be one of the best. i actaully when about to purchase my set-up was gonna go with the SLP underdrives but i followed the bandwagon and went with Steeda.

 

ive herd dont get ud pullies if ur gonna get a s/c. why?

 

Since boost is controled by pulley sizes if you put U/D pullies on your car it will screw up the boost.

 

All underdrive pulley systems so far decrease the size of the crank pulley which slows down everything else. Since the Supercharger is part of that serpentine belt system, it'll spin the supercharger slower. Some people actually put bigger crank pulleys on supercharged cars (opposite of underdrive). A company like ASP could possibly put together a system that would affectively underdrive things like your power steering and alternator while overdriving your supercharger but it'll really cost ya for all those custom pulleys.
