In this video, Race Proven Motorsports (RPM) brings us an interesting contest between two similar, yet distinctively different Corvette models. The first, wearing the beautiful silver hue, is a C6 (2005-2013) Corvette. The other car, with stunning blue paint, is a C7 (2014-2019) Corvette. Fortunately for us, that is where the similarities end. The C6 is a naturally aspirated vehicle with a manual transmission and the C7 is supercharged with an automatic transmission. The C7 also makes 800whp and the C6 only makes 600whp. Both cars are modified by RPM.

The C6 Chevy Corvette Z06 is equipped with a 7.0-liter LS7 V8 engine. Constructed with an aluminum block and cylinder heads, a dry sump oiling system and titanium connecting rods, the LS7 is the most powerful naturally aspirated V8 engine ever produced by GM. In factory trim, the LS7 was capable of producing 505hp and 470 lb.-ft. of torque. RPM has treated this silver bullet with an improved set of cylinder heads and a better camshaft. It also has a full accoutrement of bolt-ons and it has been expertly tuned.

A supercharged and intercooled 6.2-liter LT4 V8 engine propels the C7 Chevrolet Corvette Z06. A 1.7-liter Eaton TVS supercharger and a set of Rotocast A356T6 cylinder heads help the big V8 to digest all the fuel and air that it requires to produce 650hp and 650 lb.-ft. of torque. RPM has modified this C7 with a porting job on the supercharger, tons of bolt-ons and extensive tuning.

Surely the car with a horsepower advantage will prevail in this (roll) race, right? You may be shocked by the outcome.
