2021 Chevrolet C8 Corvette - Twin Turbo Beast
2021 Chevrolet C8 Corvette (Stingray 3LT)
About This Build
The mid-engine C8 Corvette revolutionized the American sports car, and the aftermarket has taken it to another level. The LT2 6.2L V8 responds incredibly well to forced induction, and several companies now offer twin-turbo kits that bolt onto the stock engine. This build uses the Extreme Turbo Systems (ETS) twin-turbo kit — ETS is renowned for their turbo kit engineering, having built kits for GT-Rs, Supras, and now the C8. Combined with supporting mods, fueling upgrades, and an HP Tuners calibration, this C8 puts down 750WHP and transforms into a genuine supercar killer. ## Mod List **Forced Induction:** - ETS Twin Turbo Kit for C8 Corvette (Garrett G25-660 turbos) — $9,500 (https://www.extremeturbosystems.com) **Fueling:** - Fore Innovations Triple Pump Fuel System — $1,800 (https://www.foreinnovations.com) - ID1050X Injectors (set of 8) — $1,200 (https://www.injectordynamics.com) - Radium Engineering Flex Fuel Sensor Kit — $350 (https://www.radiumauto.com) **Exhaust:** - Corsa Performance Sport Exhaust — $1,600 (https://www.corsaperformance.com) **Cooling:** - C&R Racing Heat Exchanger — $900 (https://www.crracing.com) **Tuning:** - HP Tuners MPVI3 + Credits — $600 (https://www.hptuners.com) - Custom Dyno Tune by Speed Phenom — $1,500 **Drivetrain:** - Dodson Motorsport DCT Clutch Upgrade — $3,500 (https://www.dodsonmotorsport.com) **Wheels & Tires:** - Nitto NT555 G2 305/30/20 front, 345/25/21 rear — $1,800 (https://www.nittotire.com) **Labor & Installation:** ~$5,000 ## Performance Results - 752 WHP / 690 WTQ on E85 - 0-60: 2.4 seconds (from 2.9 stock) - Quarter mile: 9.5 @ 150 mph ## Build Summary Total parts cost: $22,750. With labor, approximately $27,750. The C8 twin-turbo build is the ultimate bang-for-buck supercar. The ETS kit is a complete, well-engineered solution that maintains OEM fitment and reliability. At 750WHP through the mid-engine DCT, this Corvette will embarrass cars costing three times as much. The LT2 with forged internals from the factory handles this power level comfortably.
