I'm stuck between the two. How'd you make your choice? Supercharger down the road?

1) Supercharger plans

2) Ben got the UD one, this way we can kinda compare results.

Nothing to do with the fact that it is underdriven and will affect other stuff. Unless you are going SC, there's no reason not to get the UD.

im planning on going turbo, ive always heard its not good to have these lightweight pulleys on a turbo car. is that true?

RCZ · 04-04-2009, 11:12 AM

Brazilbro - for turbo it makes no difference.

Brazilbro · 04-04-2009, 06:55 PM

RCZ · 04-04-2009, 08:16 PM

You bought one too? Nice, join the club. It will be interesting to see what you will say about it since you're stock. We can compare results later on

Brazilbro · 04-07-2009, 11:58 PM

Hmm the underdrive version (but not the standard-size version) is gone from Stillen's website. What's up with that?

Yep.. unintentional.. weird even! I'll get it back up ASAP..

Sorry about that!

All this Stillen talk is making me want to take that 10 minute drive down there to check out the magic that goes on. I go to OCC, so the drive isn't too bad haha. It's practically down Baker and a left on Airway.

I want the non under-driven one, but I'd like to see what RCZ has to say about it first!

We'd love for you to.. Let me know when and I'll personally give you a tour of the entire facility..

Erm.... Sorry for sounding noob, but what is this UD pulley used for and what kind performance gains are we to expect?

I was about to explain it, then I realized that you can just Google it and get your answer. In a nutshell, your auxiliary items (like the air conditioner, for example) are powered by a crank pulley. An underdrive pulley is smaller and lighter, and sends less power to those auxiliary systems because they don't actually need as much power as the stock pulley generates. Power that is sent to those systems is power that is taken away from your wheels. So by replacing the stock pulley with an underdrive one, you are returning some of that power back to the wheels. End result = gain in whp.

Here, go to this link, it explains it more fully and better than I can: Underdrive pulleys - Wikipedia, the free encyclopedia

Edit: Here is the link to Stillen's web page for the pulleys.
