I am looking for a screw type supercharger that would fit a 1993 fleetwood running the Chevy 5.7 liter smallblock V8. So far only powerdyne has been able to provide me with a supercharger, but their is a centrifugal not a screw type. Can any one help me out?

Boy that's difficult. Not sure what to do with the TBI. I know if you had the '94-'96 with the Gen III/ LT/1 that you could probably find a Camaro one to fit your engine.

One issue I see with that is, since roots blowers typically mount in the center of the V, you might not have enough hood clearance.

Tell me about it, I have been able top find paddle type superchargers that fit into the Chevy caprice....so I'll probably go in that direction. Its just that the screw type charger give you a smoother boost curve then the centrifugal charger that needs to get up to speed.

Check apllications for chevy trucks with TBI. I think I might have seen a roots type blower made for them...

How about this http://www.superchargers4less.com/whipple/gm5.7.htm . They are all 50 State emissions legal too. Good luck.
