Another high-horsepower build wrapped up and out the door.
This 2013 Camaro ZL1 (Manual) came in stock at 460HP, but the goal was simple: make real power and keep it streetable.

The combo starts with a Magnuson supercharger pushing serious boost, supported by a full intake, header, and exhaust setup to move air efficiently.
Fuel delivery was completely reworked with a Flex Fuel system and Fuel Injector Clinic 1650cc injectors, ensuring reliable fueling on E85 at this power level.
