The supercharger is an Eaton 2.3L unit for four lobe rotors. The rotors have 160 degrees of twist. If those specs sound vaguely familiar, that because it matches the unit GM is installing on the LS9 engine for the ZR1 Corvette. This one is of course not street legal and is intended for off-road use. At 605hp and 550lb-ft, Ford claims this is the most powerful off the shelf modular motor yet. At a list price of $18,150 it may also be the most expensive running almost the same price as a base V6 Mustang. Thanks to Paul for the tip!
