The Detroit Diesel Series 60 engine is known for its reliability and power. However, even the most robust engines can benefit from performance enhancements. One crucial component for optimizing performance and longevity is the exhaust manifold. This article delves into the benefits of upgrading to a performance exhaust manifold for your Detroit 60 Series engine, specifically focusing on the PDI (Performance Diesel Inc.) manifold.
Enhancing Performance and Reducing EGTs with an Upgraded Manifold
The stock exhaust manifold on a Detroit 60 Series engine can restrict exhaust flow, leading to increased turbo lag and higher exhaust gas temperatures (EGTs). PDI’s aftermarket exhaust manifold for the Detroit 60 Series (covering 12.7L and 14L engines from 1994-2003) addresses these limitations with a design focused on maximizing airflow and reducing EGTs. This results in improved engine efficiency, reduced turbo lag, and potentially increased fuel economy.
PDI Exhaust Manifold: Design Advantages
PDI’s engineers meticulously analyzed and tested each port of their Series 60 exhaust manifold to ensure balanced flow to the turbocharger. The larger diameter runners and smoother, more gradual bends contribute to a significant increase in airflow compared to the stock manifold – approximately 20% on average. This improved flow allows the turbocharger to spool up faster, reducing turbo lag and delivering quicker acceleration.
Furthermore, the optimized design of the PDI manifold leads to a significant reduction in EGTs, often by 75-100 degrees. Lower EGTs protect critical engine components from excessive heat, promoting engine longevity and reducing the risk of premature failure. Maintaining optimal exhaust pressure to boost pressure ratios also contributes to the potential for increased fuel mileage.
Superior Materials and Construction
PDI utilizes high-quality High Silicon with Molybdenum Ductile Iron (HSMD) in the construction of their exhaust manifolds. This robust material resists warping, cracking, and heat erosion, ensuring long-term durability and performance. The redesigned mounting surfaces further enhance durability and prevent common failures associated with fatigued manifolds.
Warranty and Availability
PDI stands behind the quality of their product with a 2-year unlimited mile warranty on their Series 60 Non-EGR Exhaust Manifold. This comprehensive warranty provides peace of mind and demonstrates PDI’s confidence in their product. The manifold is available for purchase in all 50 states.
Conclusion: Investing in Performance
Upgrading to a performance exhaust manifold, like the one offered by PDI, is a worthwhile investment for Detroit 60 Series engine owners seeking enhanced performance, reduced EGTs, and increased engine longevity. The superior design, materials, and construction of the PDI manifold provide a significant upgrade over the stock component, delivering tangible benefits that contribute to a more efficient and reliable engine.
