Originally Chevrolet Corvette ZR1 generates 647 horsepower (476 kW). This mighty result is due to its 6.2 liter supercharged V8 engine. The torque number here is 818 Nm (604 lb-ft). Matched to the six-speed manual gearbox, this emblematic Chevrolet model can accelerate from 0 to 100 km/h in only 3.4 seconds on its way to the top speed of 330 km/h (205 mph).

However, these impressive numbers weren't enough for the tuners from Lingenfelter. They wanted more from this ZR1, so they decided to make a comprehensive ZR1 Package, which will boost Chevy's power even more.

Due to it the car now generates the impressive number of 750 horsepower (552 kW)! The torque here is 989 Nm (730 lb-ft). This package includes the addition of GT9 ZR1 supercharger camshaft and Lingenfelter CNC ported LS9 cylinder heads.

And although it adds additional power it still maintains a safe level of boost and supercharger RPM. The GT9 camshaft has an excellent sound quality and will not degrade the vehicles drivability or reliability.

And to go even further into details, this unique package includes the following: Lingenfelter CNC porting and polishing of LS9 cylinder heads for optimal flow, Lingenfelter multi-angle valve job, cc chambers, surfacing and spring height adjustment, Competition Cams valve springs, LS9 retainers and locks, and Lingenfelter GT9 camshaft by Competition Cams.

In addition there is also featured GM Head gaskets and head studs, 160 degree thermostat, Lingenfelter cast aluminum supercharger front cover assembly, 2.38 inch diameter steel supercharger 10 bolt drive pulley - powder coated black - 11 rib, 100 mm aluminum double bearing idler assembly, Lingenfelter LS9 solid supercharger isolator coupling, Lingenfelter ZR1 air intake system, increased boost level 12 - 13 psi.
