this roots superchargers are built to be quiet. the centrifugals are loud. you dont need to know how much boost itpushes cuz there no way to change it. uless you got a CNC lathe then you can machine your own pulley

 

riiiighhhtttt..... He had 10k bucks to blow? Cause thats about how much it would cost him to fabricate everything it would need.

 

twin turbos...no

now you can do a 6 turbo setup it just requires some minor trimming of the hood

 

why stop at 6?

 

HUH i lost you guys now 6? WTF im confused! But yeah he didnt do it to his car he said it "Bolts right on, but i wouldnt do it because you can just bigger turbos and blow an S4" almost his exact words

 

Sorry your friend is dead wrong. Ask him where he was goign to get manifolds for that?

 

lol he wasnt a friend he some guy i knew.

 

yeah i gues you could split the exhasut runners and run 12

 

You've obviously never drove a Grand Prix GTP, Lightning, Cobra or any of the like. Roots charger's are by far some of the louder. The screw charger style is the quieter ones.

As for the boost, there is a whole TON load of pulleys out there. That exact charger was on the series I GM v6. and all the pulley's are pretty much interchanged between the eaton chargers.

 

dude ive drvin 'em all. quiet and unimpressive. they have to be quiet to comply with US DOT laws. you must be thinkin of a pulley swap. and if you did swap a smaller pulley onto this S/C i challenge you to tune it.
