The ZR1 might be the fastest Chevrolet Corvette to ever come out of Bowling Green, Kentucky, but that doesn't mean it can't be improved upon. That's where Lingenfelter Performance Engineering of Decatur, Indiana comes in. They've built some of the fastest Corvettes in the world, plus some other pretty wild tuned Chevys. Their latest super-Vette is this Jetstream Blue Metallic ZR1 that Lingenfelter took out to the drag strip at Maryland International Raceway last month. The result? A best pass of 9.813 seconds at 145.74 mph.
As you can imagine, Lingenfelter made more than just a few minor modifications. The ZR1's supercharger was upgraded with a cast aluminum air intake snout and an 11-rib, 2.6-inch pulley, an upgraded air filter, a four-inch diameter intake tube with mass air sensor, a ported throttle body, and a cast aluminum air inlet all help to stuff more air into the 6.2-liter V8. Other upgrades include a larger heat exchanger, larger intercooler reservoir system, and a set of sticky R345/35R18 Mickey Thompson ET Street Radials. The finished product puts out 739 horsepower and 740 pound-feet of torque measured at the rear wheels. Want to see it in action? Watch the video after the jump.
