Please allow myself to introduce myself

Welcome aboard, wow that Duster of yours is a monster, how much horsepower is that beast unleashing or will be unleashing?

I don't have any dyno sheets, but with 5 lbs of boost my best guess is that it's around 500 to 550 hp. The great thing about the roots type supercharger is that it makes lots of power even at low rpms which makes punching the gas pedal a lot of fun.
