Performance Diesel Inc. (PDI) Big Boss products represent the pinnacle in American made quality big rig performance products. This PDI combo package converts 2004.5-2007 Kenworth trucks with C-15 Acert twins into a single turbo truck. The kit includes the majority of the components necessary for a clean installation that will deliver increased fuel efficiency, horsepower and torque. Designed for reliability, drive-ability, and efficiency the turbo is built to withstand the toughest heat cycle conditions.
The CAT C15 Exhaust Manifold has been designed to maximize exhaust air flow, reduce turbo lag time, and cool exhaust temperatures. Stock and other competitive products on the market fall short as their design constricts the airflow, increasing turbo spool response time. The hard angles on other manifold designs cause higher swirl rates and friction which increases exhaust temperatures putting more risk on the engine. With lower quality iron, a stock exhaust manifold or one from a competitor can weaken over time as the manifold expands and contracts. This can lead to cracks and even flaking. The PDI Exhaust Manifold is built using a superior grade of High Silicon with Molybdenum Ductile Iron (HSMD) that eliminates weak points such as warping, cracking, and center divider failure from heat erosion. This material, combined with a redesign of the mounting surfaces, eliminates common failures due to a fatigued manifold. Each port has been analyzed and tested to provide a balanced flow to the turbocharger. The diameter of the runners has been designed to produce, on average, a 20% airflow increase over a stock manifold. The gradual angles of the manifold have been built to reduce swirl rate resulting in cooler exhaust temperatures by 75-100 degrees. PDI manifolds help maintain optimal exhaust pressure to boost pressure ratios, providing the potential for increased fuel economy. PDI isn’t just a parts manufacturer. They are a real world shop, and they design and install every part they make. With PDI performance parts you know you’re getting only the best.
