I got the N1 3-set from Suby Sports. I love'em. They are great. Can't really say anything about the other ones though. But these are high quality and had no problem with fitting or belts, etc.

I got my N1 3 pulley set from imprezars.com Great set with improved throttle response and looks great too. I'd highly recommend it and go *booooooooooo* to underdrive pulleys. Don't know much about the Cobb pulley so I can't endorse or poo poo it.

Isn't the CObb pulley the UnOrthodox Pulley? I know their pulley had problems with some other cars but it seems to be working fine from what people around here have said.

from what I see in the one picture, it looks the same as the UO Pulley, and i'm using the UO Pulley with no problems and feel the gains too... just wonder if i hybrid the two products, what will happen... more gains or just the same etc....

edit : their site also says that their pulley underdrives a bit too so.. i'm guess it is the same thing...

I've been driving with an UD pulley for over a year with no problems. In fact, it was the first mod I did to my engine, since it's gains are incremental with other mods. I don't quite understand why people poopoo the UD pulley. I mean, I like the lightened pulley set, and you can use stock size belts, but I can find the Gates belts that fit my UD pulley with no problem.

Besides the headlights dimming a bit, what exactly is the problem people are seeing with the UD pulley? I haven't seen any problems.

That's not enough for you? Try hooking up some amp and subwoofer and see what happens.

I'm thinking for those hot summer days where you find yourself using the A/C. The whole UD thing will just worsen exponentially and really drain power away from your car when the A/C compressor is on.

I say go for the N1 three pulleys. Makes it look stock and not have to worry about dimming. Overall I think the weight saving are greater also.

amps and subs? what are those doing in there? do they make the car go faster?

i wouldn't underdrive for the simple fact that there's no gain to be made vs. a 3 pulley set. additional strain on your electrical system/accessories is debateable...sure, it may cause no problems in the immediate future, but why set yourself up for risk further down the road when there's no reason to? to me that's worth the few extra dollars. and if you're on a trip and a belt breaks, stock belts are going to be much easier to find.

having said that, if i were in the market for a pulley set again, i'd go for the 'go fast bits' pulleys from australia over the N1 set...my N1's had numerous small flaws in the machining, and the anodizing was pretty sketchy out of the box...it started coming off during installation, and looked like that metalcast duplicolor paint -- not anodized aluminum. but they get the job done, and they were free, so i can't complain too loudly.

i saw a set of the GFB pulleys this weekend, and the machining and finish on them is beautiful compared to the N1's...nevermind the silly name.

Well, I don't have any amps, etc in my car and don't really want any. Since the alternator is under-driven, it should put LESS stress on your alternator, not more. It's spinning slower.

I've used my AC and haven't had any problem with that. It still seems as cold as ever.

The under-driving done by the unorthodox pulley is not that extreme and the electrical system lags only at idle (500 or so RPM). When my car is running at regular RPMs, I don't see any difference in how the electrical system operates, IE: lights are normal, AC works, Stereo sounds good.

So that's my .02

I will agree that getting belts on a road trip may be harder than stock sizes.

I just saw the GFB lightened pulley set from Teague's Subaru. The description said it was a "slight" undrive, but it comes with an alternator pulley also, which probably fixes the problem.

Looks good and comes with belts!

Dude, you will see results immediately, no matter what pulley set you got. I've read that a pulley/pulley set is one of the best bang-for-the-buck mods you can get.

Good Luck!

well, there really isn't much more info to give really than that it is a lightened set of pulleys (i believe there is info on www.imprezars.com that shows the difference in weight). there isn't any more special thing about them that you can find out... hmm yeah...

Thumbs up pulleys?

UOR underdrive = not that good a deal IMHO.
N1 = $250, but probably worth it.
GFB = $220 @ www.vividracing.com
the GFB pulley set includes two lightend pulleys and one underdriven. there is no doubt in my mind that the GFB pulley kit will give the most gains over the other options.

I hope this helps
