Supercharged LS9 fires up 2009 Corvette ZR1

GM has recently announced that a supercharged LS9 smallblock powerplant will find its way under the hood of the extreme performance 2009 ZR1 model. Engineers are targeting the 100 horspower-per-litre benchmark for the new engine, which is based on the new 6.2 litre V8 currently found in the standard Corvette. If the guys in the white coats meet their goal, expect horsepower figures upwards of 620- though you'll have to wait untill March for the official number.
