Rick’s 2019 Chevrolet Corvette Grand Sport, finished in a fitting Sebring Orange Tintcoat, comes out of the box as a great platform, sporting loads of performance straight from the factory. With plans to track the car on road courses, Rick wanted more. The objective for the C7 was simple: increase throttle response, allow the engine to breathe better, and increase power. With a plan in place, the car was pulled into the shop and the build commenced. Build list below:
Pre-existing modifications:
• aFe POWER air-intake system
• CORSA Performance cat-back exhaust system
Performed by us:
• MSD Performance Atomic intake manifold
• Katech drive-by-wire 103mm throttle body
• Kooks Headers and Exhaust 1.78″ primary OD long-tube headers
• Kooks Headers and Exhaust 3″ X-pipe w/ high-flow catalytic converters
• MSD Performance spark plug wires
• Design Engineering, Inc. Protect-A-Boot sleeves
With the mechanical work wrapped up in the shop by Andrew, Matt strapped the C7 down onto the rollers for a custom calibration by Vlad via HP Tuners. With 93 octane in the tank, Vlad increased the LT1’s output to a solid 449.15whp & 455.32lbft, sending power to the rear wheels through an 8-speed automatic transmission. With the upgraded dry-sump lubrication system in the Grand Sport models keeping the oil pumped into the engine during sustained cornering and the added width of the fenders and body in contrast to the base model, you can say that Rick made a great choice when choosing the Grand Sport as a weekend cruiser and track car.
