Not to open up a discussion about the pro's/cons of the UR pulley; but I installed mine yesterday. A few comments:

1. I did 99% of the install by myself (wife came out and stepped on the brakes while tightening the pulley bolt).

2. It was surprisingly easy with the right tools.

3. Setting the breaker bar on the floor works really well. Many things shot through my mind as i turned the key but after I did it, it makes total sense.

4. Performance gains; well no dyno but I do notice it down low and rev matching seems way easier.

5. All in all I think i'm really looking for F/I (and yes i know the pulley will have to come off)

 

I felt a good gain with mine.
Tried 3 hours to take the pulley off, but it was totally stuck, so took it to a shop. pulley works well with other boltons.

 

pully will stay if you go turbo

 

Thanks for the pulley by the way!

Also, please send me an APS TT setup for a G35 coupe.

 

Your welcome!

Im out of free kits at the moment, but I can send you a quote!
