Chevrolet Performance LSX Real Street Gains New Competitor For 2013

Over the last couple of racing seasons, Chevrolet Performance’s LSX Challenge series has been growing exponentially, and one of the reasons is the Real Street class. The engine and power-adder limitations have made the class attractive to build for, and Indiana’s Todd Williams is one racer inclined to step up his program for the coming season. His team from RPM Transmissions has had success with their C5 Corvette in the class, and although this particular C6 was originally destined for other competition, the decision has been made to build it into a nitrous-gulping small-block monster for Real Street.

The engine program features parts from some of the best names in the business, starting with one of RHS’ standard deck-height blocks holding in a Callies Magnum crankshaft, GRP aluminum connecting rods, and JE pistons. A camshaft that features nearly one inch of lift helps to meter the air into the Chevrolet Performance Parts DR heads filled with Victory Racing, Jesel, and Manley parts. Induction Solutions’ Steve Johnson supplied the nitrous system for their other car and will continue to do so for this program. In addition, an AEM Infinity engine management system will be on board to keep the engine running in optimal shape.

As RPM Transmissions is heavily involved in the Corvette aftermarket, the car will feature a full contingent of RPM’s parts including an SFI flexplate, converter drive plate, and custom Powerglide transmission. The car also features a long list of driveline upgrades including Driveshaft Shop CV axles, propshaft, and couplers. As the class is currently running in the mid-eight-second zone at around 160 MPH, the decision was also made to install a complete 25.5-spec rollcage to protect the driver in the event of a mishap. The build is just getting underway, so there aren’t a ton of photos yet, but this is one work in progress we think you’ll want to follow.
