just wanted to know if anyone has this?

it looks like my underdrive pulley but it says its an overdrive.

Yep it makes the accessories spin faster. Big whoop. Why do you want one? Do you need your alternator and A/C to spin faster? Or do you have a supercharger you're trying to spin faster without putting just a smaller pully on the supercharger?

Just looked at your profile. You're running an underdrive pulley right now with the supercharger? lol

no not anymore took that off it killed the boost i was going 2 order this with a 2.6 pulley.

for my charger

whoa... did not know obx was making us overdrive alt. pulleys... its definitely something new that hasn't been out long. so i doubt many if any at all have it.

looks pretty sweet, actually.



I'm tired of wasting my time... now I'm breakin' free.

LMAO!!! Another great OBX copy....

i also found this site if its new its new if its not its not.

It is an under driven pulley. It is larger than stock, which would make the alternator actually spin slower......Just like the AEM alternator pulley....which happens to be the same size. ~Cough~
They copied the AEM pulley, and changed the lighten holes.

Big-small: Overdrive. Small-big: Under-drive. Bigger than stock: Overdrive. Smaller than stock: Under-drive. Are we clear now?


Go beyond the "bolt-on".

Crank pulley....
Larger than stock....Over driven
Smaller than Stock... Under driven

Alternator Pulley
Larger than stock....UNDER driven
Smaller than stock....OVER driven


Now are we clear.
