The aftermarket has been unable to crack the C8 Corvette’s encrypted ECU so far, but that doesn’t mean power enhancements for the new Stingray aren’t already available or in the works.
For example, California-based Boost District showed off their forthcoming three-stage system at the recent 2021 SEMA Show in Las Vegas.
The company claims to have developed the first supercharged C8 with a positive displacement blower for the Stingray’s 6.2-liter LT2 engine that produces 495 horsepower from the factory.
“We built the entire supercharger system for the C8,” Boosted District President Roshan Poptani says, “and the only thing that is off the shelf is the LT5 lid (used on the 2019 ZR1) that we used for prototyping and the Eaton TVS R2650 rotor pack.”
Three levels of power will be available, all retaining the factory ECU, with the entry level option being Stage 1 that uses six to seven pounds of boost and a spark and MAP controller to create 650-700 horsepower at the wheels on pump fuel.
For Stages 2 and 3, Boosted joined forces with another company, with Poptani telling lsxmag: “We’ve been working side-by-side with Anderson Dick at FuelTech USA to give a plug & play ECU control with port injection.”
Stage 2 is expected to support 9 to 10 pounds of boost, and the ultimate Stage 3 for those using forged pistons with an upgraded clutch should support boost levels in the mid-teens.
Horsepower figures for the top two stages are expected to be provided soon.
The systems use TVS2650 rotor packs to ensure no added maintenance with OEM reliability and have an intercooled manifold to keep temperatures stable, CNC machined housing to provide efficient airflow throughout the system, provisions for port injection, bolt-on heat exchangers with fans, quick-release pulley hub, allowances for different throttle body configurations, and no frame modifications.
Poptani says the setup responds like a stock C8 “until you put your foot in it, and then it comes to life as it makes peak torque at 2,300 RPM.”
Pricing is expected to be announced before the end of the year, and you can get more information about the systems at Boostdistrict.com.
