AEM - Tru-Power Pulley Kits.. (Lightened and Enlarged)... What will this do for my car? (Sorry, newbie at performance here)

More power......but what it will probably do is balance out the power on yer car when you put the AC on....but you migh notice a small increase...it is an underdrive pulley

Yeh, they are underdrive (accessory) pulleys. They take weight off and spin with less resistance thus creating a smoother flow
and a slight power increase. Wait for the Unorthodox Racing Set to come out, it should be here in the next month or so. Unortho has a set called the Ultra SS Street Set and it comes with the two pulleys AEM comes with, but also a Crank Shaft Pulley, and that my man, is where you get the most power gain. They say on a NA engine, they can get you up to 10 HP ??? But who knows for sure.

I've alreayd got the AEM pullies but havent put them on yet, do you think you can buy just the crankshaft pulley from unorthodox when it comes out?

Yeh, I'm pretty sure you can....and I think they'll be like 225 dollars for the single crank shaft pulley.
When they finally hit the shelf, you'll know it, I'm sure someone will do a post on it....but here's the link for the site and the pulleys.

Scroll down to the bottom of the page and you'll see the sets and single pulleys.

There may be a problem with the alternator not taking the increase of rotation.
It happen to a friend with a 2k1.

Did your friend install them himself, or did he have them installed by a shop ??

And yes, they will add some noticable power....I hope !! : )
