Power Pulley Kits Question

Anyone Know The Pros and Cons of getting a power pulley kit???

Like the UNORTHODOX Ultra Street Pulley? I believe it adds 5-12 hp. (depending if its a turbo or not.) I was looking at pulleys for a while. Hope that helps at all.

Im not sure, but I hear alot of bad talk about pulley kits, but on the other hand I hear People praising it, saying how good of a gain they got,
my final question is----Should I get it or not

90 legacy M/T 2.2 ltr
sigh.... No Turbo

Power Pullies usually add about 5-10HP from what I've been told. Most are underdriven, meaning they rotate the accessories less for ever rotation of the engine. Your alternator will put out less and your AC won't be as strong, but you'll puck up 5-10hp...I'm going to go with Cobb's Pulley when I get my new car in spring.

i put a set of the unorthodox pulleys on my friends 2.5 legacy, he was looking for more juice since its an auto. It made a slight difference. Just watch it because if you underdrive the alternator too much it obviously wont charge as well, especially if youre running a decent sound system, aftermarket headlight bulbs etc.. A drop in the subaru voltage system eats up starters fast.

It becomes a real problem with aftermarket highpower Stereos. You could get a lightened pulley to replace the stock one (doesn't underdrive). Its the same Diamter, just lighter. I hear this helps add 2.5hp per lbs lighter than stock.
