Default Unorthodox Racing pulleys

I bought the Limited Edition Subaru pulley set a few months ago and had it installed at GRD. The mechanic at GRD warned me about the poor quality of the UOR pulleys since he worked with a few in the past. He was right. The alternator pulley was too big to fit into the housing. The power steering pulley didn't line up with the crank pulley; it also had to be forcibly installed onto the spindle. The crank pulley also didn't fit quite well. If one pulley didn't fit well, I would understand; maybe it came from a bad batch but all 3 didn't fit so I have to question the quality of their machining. I've sent them an e-mail. Hope to get a response soon.

Hmm.. Sure the car wasn't too hot? Had a similar problem during an install fest when we did at least like 6 sets of pulleys. First 5 or so went on with no problem, the last set was being installed on a HOT engine (pulled right into the driveway after a 40 or 50 mile drive). Needless to say, we needed to let the car cool down a good half hour or more to get the pulleys easily. After the car was cooler (and the pulleys hotter from sitting on the manifold) they slipped right on.

jimb,
My car was sitting for almost an hour before the mechanic worked on it. I just got an e-mail from UOR stating that they had some problems with the first few alternator pulleys; some sort of trouble with the alternator housings; they were supposed to send out a memo on it to me but I never got it. In any case, UOR is going to machine it to the correct diameter for me no charge. So although the product was faulty, at least the service is good. As for the mechanic, I think he was competent (and honest); he offered to put the alternator pulley in for free once we got the part machined. I'll be mailing the pulley back tomorrow so hopefully it'll be back soon. I'll keep you guys posted.

No big difference really although it does seem to rev faster. The complete set isn't on yet so a final evaluation will have to wait.

I received the machined pulley last Friday and I'll be putting it on this weekend. I'm kind of disappointed in the machining quality since I expected it to look like it did before (smaller of course) but the machining marks are obvious. At least no one will see them. Can't wait to get it installed.

Hey, this is called a PRESS FIT...it is supposed to be like that, the diameter of the hole on the pulley is smaller then the crankshaft. They are engineered like that.....just so you know, your mechanic is a retard. You just have to have someone hold your brakes down while you torque the hell out of it. It takes a while....but enventully everything lines up...i think the specified lb. ft is 105 or something.

jbowser,
Thanks for the info. The torque specs for the crank pulley are 75-85lbs per UOR. I'll be installing the alternator pulley soon so we'll see how "press fit" this pulley is.

Finally got around to installing the UOR alternator pulley. Removing the OEM pulley was a breeze with my friend's impact wrench. The UOR pulley fit perfectly. The belt that was supplied (21mm x 890mm) was not the correct length. I went to Carquest and got a 21mm x 925mm which went on perfectly. Any difference noted? Not much although the car revs a little quicker and the pulleys look cool in the engine bay. Supposedly, these lightened pulleys will free up about 4hp but I can't honestly tell the difference.

And it's back from the dead.....

Installed a set of UR pulleys for my 2004. The under-driven crank, alternator, and power steering.

They slipped on smooth as silk without any massage, and torqued down easy.

The two new belts I purchased were manufactured by Goodyear. Their new top-o-line Gatorback.

A/C belt was P/N: 4040340 (4 groove 34 inch)
Alt/PS belt was P/N 4050340 (5 groove 34 inch)

The 34" Alt/PS belt was almost too big: If I were to change it I'd buy a P/N 4050335 (5 groove 33.5 inch) and it'd fit perfect.

There's a noticeable increase in engine power. We're not talking "Holy **** Space Shuttle Power" but butt dyno noticeable.

Follow up: 2.25 years later. All three pulleys work out great.

Pulleys
The under-driven alternator does let the headlights dim slightly when I'm idling. I've become used to it. You don't really need the lights at full bright when you're just sitting there anyway. While driving around the headlights are as bright as normal, no perceivable difference.

Didn't notice any problems with the power-steering. Even while coasting (engine at idle) and turning aggressively. That's not to say that you won't have problems if you **** up and rotate the p/s pulley backward or otherwise get air in the lines during install. If you did that it's not the under-driven pulley fault; it's your dumb ass.

Belts.
Defiantly get the 33.5 inch belt for the alt/ps. Goodyear Gatorback P/N 4050335 (5 groove 33.5 inch) The 34 almost maxes out the system. I'm talking 2 threads left until max. And you can not get a 33 inch on there unless you use a pry bar. If you're using a pry bar to get a belt onto aluminum pulleys you need to reevaluate your suitability to work on cars.

For the a/c the 34 inch belt works fine (P/N: 4040340). There's enough play that you could use the shorter 33.5 inch (P/N: 4040335) if you wanted. 34.5 inch would be too long. And, not that I've tested it, but I would estimate the 33 inch would be too short.

Bottom line 2.25 years later I'd still recommend this upgrade.
