Reason: Added HR disclaimer
No, they are for 03-06 only. I need to edit the post to include that info, AMS is supposed to have HR pulleys for us soon but they haven't given me an ETA yet. Sorry.
so.. this isn't a underdrive pulley? how does it make power? do you have a link with more info on these?
It's not underdrivem it "makes" power by reducing the amount of rotating weight on the front of the engine. By reducing rotating weight you reduce parasitic drag which allows more engine power to transfer. Works just like lightweight flywheel does in regards to power gains.
