2019 Corvette Grand Sport – A&A Supercharger

Some cars come and go, and some cars tend to stay forever. With Philip's latest acquisition of this 2019 Chevrolet Corvette Grand Sport being a sentimental one, this C7 is here to stay.
With the decision being made to keep the car, the desire for more power couldn't be avoided any longer, so a plan was set in place to get this C7 Grand Sport tipped over the 500whp mark!

With the mechanical work wrapped up in the shop by Andrew, Matt strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners. With 93 octane in the tank, and the Vortech V3 Si delivering ~8psi, Vlad increased the LT1's output to a solid 566.23whp & 551.72lbft! Some pretty outstanding numbers considering this C7 is still on the stock fuel system!
