Get better fuel efficiency and drivability from your Caterpillar C12. The Big Boss Turbo design has been created to withstand the toughest heat cycle conditions adding reliability with performance and efficiency.

Designed to keep the turbo in its efficiency range it utilizes a V-band style which eliminates the need for the traditional o-ring design of some engines. Built with precision to get the A/R ratio to move air at the most efficient range possible. Like all PDI products, they are designed to make more horsepower and create more efficiency so you save money while making the drive more enjoyable.

Stock turbos restrict the volume of air causing the response to be slow and the exhaust temperatures to run high. With the PDI Caterpillar C12 Turbo, you’ll keep the temperatures down and decrease the strain placed on the engine as you see more horsepower and fuel efficiency.

Excellent must upgrade for c12

Have been looking for an after market upgrade turbo for sometime. Have already installed exhaust manifold through full tilt. Turbo boost now max out around 35 psi before only about 21 psi. Exhuast temps noticeably lower along with coolant temps when pulling long hills. Haven't had enough info for fuel mileage because winter has set in and need more data.

Totally Awesome

We have this turbo and the Big boss tuner on our 2000 model sterling with a Cat C12 and let me tell you, it flat out pulls like a freight train. I can haul two 60ft jlg manlifts at the same time and the little C12 doesn't mind at all. Getting better mpg and egt's are down.
