I have a 2004 H2 that has a magna charger, headers, and a forced air intake. The charger is very loud at times and doesn't seem to have the power that you would think it should. I bought the rig used and it has been like this since i have owned it. Just curious if this is right or if i have a problem.

 

pop off the belt and see if you can feel any play in the pulley.

 

Noise is normal in all "roots" style superchargers. When they do get older they will get louder, you should call magnacharger and talk with one of there techs on the issue. Here is the number

805-289-0044

I am sure its not a big problem.
