Gwatney Performance Innovation can perform nearly every performance modification imaginable to a wide variety of vehicles. Custom ground camshafts have become a mainstay at GPI – especially for the LSx motor platform. We often venture into Supercharged and Nitrous projects – and bring the total package together with a custom tune using our own in-house DYNO.

Cold Start & Truck Tuesday
Day 13 : 🪓GPI PD2 Blower Cam🪓
Tailored for the street / strip individual that runs a 2500+ RPM converter. It rivals the torque output of the LT PD1 but packs on about 10-15 additional horsepower up top. Strong to 6700 RPM. Can run a factory converter but an upgraded converter is recommended (We know no 10-Speed converters are available). Requires 0* phaser limiter.
