has anyone here upgraded there cam shaft or got an underdrive pulley if so does it give you a good amount of HP?

 

big time gain short of my turbo it was my best power gain. worth every penny.

 

im working on installing a new cam with all the tastey goodies (cam gear, valve springs). I am taking it to the dyno December 2nd (im hoping I have everything done to it that soon), and I will post up the dyno results when I get back!!

It will be some work for sure, but I am hoping to see some good gains.

 

The underdrive pulley was the first thing I installed on my car. Not much of a difference with the ac off but when the Ac is on you can really feel a difference.

As far as the cam goes, It's a nice upgrade. I haven't pushed my car to the limit with my new stuff on yet but I will as soon as I get everything right. Sounds nice too.
