Hey this is my first post so try not to be to critical but anyway i bought a underdrive crank pulley and shortend belt for my cobalt and im wondering if theres anyone else out there that has one. I havent heard anything about them in any forums. Im putting the pulley on this weekend and im really wondering what difference i will feel. Anyone out there that could help? and maybe some install tips, it looks a little bit tight to get it

 

anyone?... this is my next mod too

 

i know jn2 has one..search him up in the members list and PM him

You won't "feel" any difference. You may notice the RPM's climb a hair quicker, but not much. In general, light weight pullies usually lead to really bad engine problems down the road.

Good luck. Hope all goes smoothly for you.

 

I have an underdrive pulley on my other car and you will notice a slight difference. It will rev up faster mainly. I know you will have to jack up the car and remove the front/right wheel.

 

search the how to section, i made a thread on it including videos
