Default Stillen Under Drive Crankshaft Pulley

I had my under drive pulley installed the other day, and I can feel a noticeable difference in power. I think it's a great mod if people don't want to do aftermarket exhaust and intake and want a little boost in power. Or, if you already have those mods and you're running out of stuff to do, don't over look the pulley.

I'm attaching a link to Wstar's journal. He did his own install and included some pictures.

Yeah I was pretty impressed with it too. Engine is more rev-happy and responsive. Still no issues after ~1,300 miles on the pulley. My A/C works great, my battery hasn't died, etc

You're probably feeling responsiveness more than power. The throttle response should be sharper and the rpms should drop quicker between gears. As far as direct HP I can't see it adding more than a couple of HP. It's definitely on my list of mods though.

Just out of curiosity, does installing the underdrive pulley void the Nissan warranty?

They are so stupid at Nissan dealers they would have NO idea it was even installed. Also, they'd have to prove it caused the problem.
