MagnaCharger is now making a complete Roots-type super charger for 99-up GM trucks/suvs. /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif Dunno about ya'll but I've been looking for something like this for a while for my 99' Silverado 4x4. I've seen a ton of centrifigal(sp?) type chargers around, but this is first roots type I've seen in a kit. Got to get one!
