Pros: Lowers the amount of parasitic lost to the engine
Cons: Not the easiest Installation, Hard to notice an increase in power

I\'ve had the UR pulley on my car since january of 2004 and haven\'t noticed any adverse effects pertaining to the reliability of this product. The only drawback was that I was expecting a noticably difference after installing the pulley, which I didn\'t receive. I did notice that the motor does rev easier after the Pulley was installed. Overall I am happy that I purchased this modification for my Spec, and I know that most of you will be aswell.

The fit and finish of the pulley is incredible! the Pulley weighs (Approximately 14 ounces) roughly 20% of what the stock pulley weighs, what this means is that you are able to now free up horsepower that would have been used to turn the heavier stock pulley. The Installation is relatively simple if you have the correct tools and patience, I wouldn\'t recomend trying to install the pulley if you don\'t have a \"pulley puller\" (can be purchased at most automotive stores).

Pros: lighter
Cons: none

Decent product, can\'t say I notice a difference performance wise, but it does weigh less than the stock unit. And it must effect performance somehow, just not in a way I can feel.

Pros: Easy mod, reliable.
Cons: not much power

This is one of the mods to leave for last, dollar per performance gains are not much (if you are getting this new).

Engine revs easier while in nuetral and while you are not likely to feel the benefits on the butt-dyno, rest assured it\'s helping out, minor mods add up.

No problems after almost two years of use - Great.

Pros: Quicker revs, lighter
Cons: No other real gains

I bought this used in a \"package\" deal including a header. I can see quicker revs but other than that no real gains. Any power gains come down low so its hard to tell on this car. Id leave this mod for last at gains/dollar are not as good as other mods

Pros: less rotational mass on the crank, a slight rev gain
Cons: was there a power gain? kinda expensive

no noticable power gain. but a easy mod. kinda expensive for such a little power gain. quality is great.

Pros: Easier Revs
Cons: No major gain

I would recommend picking this product up used... that's what I did. I got mine for 125 off of ebay. It's not like these things can go bad. The pulley looks great, fits great, and makes the engine rev very quick.

However, it was a B**CH to get the old pulley off and there were no NOTICEABLE gains. Unorthodox claims 3-5 whp, but you don't feel anything because the pulley gradually picks up power over 10 days, as your ECU adjusts to it. The power is there, but you can't feel it...

Good mod in combo with BSR.
