Remember the pump gas 1,000+ horsepower 457 cubic-inch twin turbo C6Z that we finished a couple of months ago? Well, the owner bought a mint '12 Centennial Edition ZR1 for more daily driven fun and he didn't waste any time at all bringing it by the shop for some Vengeance Racing upgrades. This time, we played it cool with the mods, but still managed to pump out 707-rwhp on 14 pounds of boost using regular ol' pump gas and the stock cylinder heads. Of course, we'll be upgrading those eventually.





Engine:
Vengeance Racing Camshaft Kit PLUS
LPE ZR1 Snout with custom port matching
Nick Williams 102mm throttle body with custom port matching
LPE high-flow cold air induction system
American Racing Headers 2-inch long-tubes with an off-road X-pipe
B&B Fusion exhaust (Mild 2 Wild)





Boost:
Stock ZR1 supercharger
2.60-inch upper pulley, 14-inch lower damper
LPE 100mm idler kit and a solid isolator
Vengeance Racing heat exchanger system

Results:
The ZR1 made big power stock, putting down 532.18-rwhp and 511.40 lb-ft of torque. That was on 9.7 pounds of boost and the factory calibration. After the Vengeance touch and tuning by Vengeance PCM, the ZR1 woke up big, laying down 707.62-rwhp and 672.80 lb-ft of torque.
