I was looking around and found that powerdyne superchargers are cheap... Is it cuz they suck? Why does no one have them?

 

I am interested as well, the whole quiet belt drive seems cool.

 

they are ok for a street cruiser but not made for racing...they shred belts unless they upgraded the drive system. If you can get them dirt cheap then go for it. I was just reading an old magazine i found in my garage and it had the new for then 4.6 head unit tested on a stock 96-98 GT and it gained 90rwhp on the 6 psi so thats ok.

 

Ive seen them go for anywhere between 2300 and 2600 for new kits.
