Description
939whp 2015 Chevrolet Corvette Z06 2LZ in Arctic White with 21,500 miles listed for auction! The owner purchased this C7 Z06 in stock configuration in 2023 before having it comprehensively upgraded by the team at Race Proven Motorsports (RPM). The car was outfitted with their Stage 4 Performance Package, which includes several quality components, dyno tuning, and an invoice for the work performed. Power comes courtesy of a cammed 6.2L LT4 that’s topped with a Kong Performance Stage X CNC ported LT4 supercharger, and linked to a Tremec TR-6070 7-speed manual transmission with a Monster LT1-S triple disc clutch assembly. More specifically, the LT4 was equipped with RPM’s custom LT4 AFM delete camshaft package, which utilizes their “Big” LT4 forced induction custom camshaft with 32% fuel lobe 231/247 113LSA. The camshaft package also includes all supporting valvetrain components, including 3/8” pushrods, Brian Tooley Racing valve spring kit with titanium retainers along with several GM branded components. This setup makes use of the factory blower, however it received the “Stage X” CNC port work from Kong Performance along with a 2.3” Griptec upper pulley, which turns the 1.7L LT4 into a beast. The supercharger system also features a powder coated DSX supercharger lid, Innovators West 18% overdriven harmonic balancer, HD supercharger belt, and a Nick Williams 103mm throttle body that’s being fed by a Roto-Fab 5” Big Gulp cold air intake. Power generated from this setup is supported by RPM’s custom external low-side fuel system, which consists of a Holley fuel pump, Holley in-line fuel filter, Aeromotive fuel pressure regulator, GM flex fuel sensor for E85 capability, all connected with AN Fittings and Fragola PTFE Hoses. Additional upgrades include a pair of 2” Kooks long tube headers with a 3” off-road x-pipe, Motion Raceworks billet catch can, ProMeth methanol injection system, RPM coolant expansion tank, AFCO Racing heat exchanger, WELD Racing Belmont drag pack (OEM rear wheels will be included as well), and more. Tuning was completed by Fran Schatz of Race Proven Motorsports with a custom ECU calibration via HP Tuners, resulting in an output of 897whp/842wtq on 93 octane and 939whp/882wtq on E85. As for performance metrics, the car went from 60-130mph in 4.83-seconds, Dragy confirmed. There are currently only 5K miles on the setup.
