Corvette Performance Packages

Excelsior Motorsports takes the guesswork out of producing big horsepower. Our dyno proven combinations are all your Corvette needs to develop the big power numbers you're looking for.

The new, direct injected LT-1 and LT-4 supercharged engines found in the C7 Corvettes represent the forefront in technology from GM. These engines respond very strongly to the additional airflow that our engine modifications provide.

The LS2 / LS3 / LS7 / LS9 generation of C6 Corvettes represent the best developments of the last decade and offer proven reliability in numerous performance applications.

C5 Corvettes may be the model of yesterday, but we've been able to extract huge amounts of horsepower from the LS1 / LS6 engine family since they rolled off the assembly line.
