Well, for what it's worth, I like my unorthodox crank pulley alot. I also have N1 lightweight pullies on the accessories, and like those alot too. I'd recommend either of those brands.

it revs faster after installed right?

Not enough to notice. (for me, at least)

It does seem to run smoother, though.

As for performance, back when my RS was stock, I raced it with a friend of mine who also had a stock RS. We were both neck and neck. I installed the pulley, and we raced again, and we were still neck and neck. (read: not much performance gain w/o other mods)

I also have the N1 Pulleys, can't tell you if they make a difference yet, but when I get to the tracks I will... I purchased my set from subysports.com. Just make sure when you install them the belts are tight enough. Instructions are in the mods section.

With my unorthodox underdrive pulley, I can rev-match much easier... and theres a big gain in first and second gear for sure.

what about the GFB kit

The unorthadox only replaces the one pulley, the gfb kit replaces three of them..

i know by underdriving the alt, it will suck of the electrical system.

If you'd ever consider getting a supercharger down the line, I would suggest buying a lightened, but not underdriven, pulley. With an underdriven crank pulley, mess with your boost on a SC.

I'll probably grab a SC in a couple years, so when I get a pulley, there's no sense in getting an underdriven one....

The GFB's underdrive the crank but match it to the alt. So your alt will still run the same as it did before. The only thing that will be running slower (less power) is the power steering. But you won't notice that unless your parallel parking.

is it a good kit or is it a waste of money??

I am trying to decide to go with this or save for my MRT header and mid pipe

I just order my Cobb CAI, and I have a scooby sport back box.

not sure on what I want to do next

Save for the header and midpipe, thats a much bigger power difference compaired to a pulley kit...
