I've got a buddy who has a brand new Powerdyne 6lb kit that he decided not to install, so I could pick it up for a pretty good price. I know nothing about superchargers, so with my current setup would I see good gains, and how reliable will it be with the currents mods on my car? Will I need a rebuild shortly after? Also, what other parts would I need to add to get the best results? Currently, my car is running 10.75:1 compression with the following mods:

Compression seems kinda high to be supercharging, but its always worth it.

 

The 6# kit will give you 4 n change so you'll be ok.
