As you may remember from our November article detailing the 2008 Chevrolet Corvette ZR1's LS9 engine, the target output was 630 horsepower from a 6.2 liter aluminum small block.  With such big block-jealous power figures, Chevrolet incorporated a newly designed Eaton positive displacement supercharger.  Stay seated after the jump to check out GM's small block engine program's assistant chief, Ron Meegan, as he explains the ins and outs of the all new Eaton unit and what makes it so unique to the ZR1 platform.  Be sure to also watch Ron break down the differences between the LS9's Eaton and the Cadillac CTS-V equipped unit.
