Corvette ZR1 rated at 638hp
The official dyno numbers are in: The supercharged 6.2-liter V8 in the forthcoming Chevy Corvette ZR1 cranks out 638 horsepower.
That's about 20 hp more than the estimates from General Motors' powertrain gurus when they unveiled the new ZR1 and its monster motor last December.
All that power will push the Corvette ZR1, which goes on sale this summer, to a top speed of more than 200 mph, GM says.
What about the grunt? The official number is 604 lb-ft of torque.
The key to that making all the horsepower and torque is a Roots-type supercharger with four-lobe rotors that sits atop the LS9 engine. A liquid-to-air intercooler is integrated into the supercharger's housing.
