      So, I know there are lots of threads on this and I have been searching - lots of good reviews, some unfortunate posts about a guy who installed it and can't get this rattle to go away after 1 month...

      Basically, my Jetta is my daily driver (~2k miles/mo) and I love it, but there is just something about the slow low-mid range acceleration that I don't really enjoy. I just bought the pulley yesterday, and it should be here today, but I'm still a little skeptical to put it on.

      Does anyone have any insight on any noticeable differences in acceleration from experience? ...issues?

      And of course, was it worth it?

      MKVI Jetta here. I just had one installed on mine last Thursday -- had a bunch of unrelated codes come up so I had to drop her back off last night, thus never got to feel'r out. Will let you know when I get her tonight!

      how easy of an install is this? Also for those who have installed this, did you do the light weight or the underdriven pulley?

      I have the pulley on my Rabbit and you definitely feel a difference. Engine revs a little faster and better throttle response...good for a simple mod

      Installation is pretty easy (about 30-45 minutes). Just install when the car is cold or the bolts will be a PITA to take out!!! - could end up stripping. Pulley is located on the passenger side of the car. Jack the car up, remove the wheel, unbolt the fender guards enough to pull them forward a bit towards the front of the car and your pulley will be right in front of you. Use a socket or wrench for the tensioner.

      Tensioner:


      Remove the belt and then remove the Allen bolts to the pulley. Re-install in reverse order and youre good. Tighten all bolts to torque specs.

      Oh and the ECS pulley is a lightweight underdrive pulley. One comes with a belt and the other doesnt which is why theres a price difference on the site


      Theres no noise coming from mine so maybe the guy that is having problems may have a pulley that is warped?

      What are the torque specs for the pulley bolts?

      I'm thinking of ordering the lightweight crank pulley.

      I've got a nuespeed power pulley ...for now.

      There are about to be a couple full pulley sets available. One will be a nice lightweight set from Gruvenparts and the other one will be very special.

      Most of our pulley nightmares should be solved by the second one
