do88 Performance BigPack for 996 Porsche 911 Turbo, Turbo S, Turbo X50 and GT2 [BIG-360]

do88 Performance BigPack for 996 Porsche 911 Turbo, Turbo S, Turbo X50 and GT2 [BIG-360]

The do88 Performance BigPack for the 996 Porsche 911 Turbo, Turbo S, Turbo X50, and GT2 is a comprehensive upgrade package designed to deliver exceptional performance. This kit includes high-performance charge air coolers, a high-flow Y-pipe, and all necessary hoses, accessories, and mounting hardware for easy installation. While the intercooler kit and Y-pipe provide impressive performance individually, together they create a powerful system that reduces inlet temperatures, enhances airflow, and decreases back pressure across the system. This combination results in a significant increase in power and overall performance, making the BigPack an ideal upgrade for maximizing the capabilities of the 996 Porsche 911.

Intercooler

• To ensure optimal airflow distribution across the entire core, the do88 Performance Intercoolers feature cast, flow-optimized tanks. A well-designed tank is critical for maximizing heat transfer and flow efficiency. To accommodate the thickest possible core for enhanced cooling capacity, the original upper air guides have been replaced with custom-designed carbon fiber guides developed by do88 using 3D scanning technology. This ensures a precise fit with both the car’s bodywork and the large intercoolers. To further optimize cooling, these air guides are equipped with seals against both the intercooler and bodywork, preventing cooling air from bypassing the core. The intercooler connections are 70mm (2 3/4″) in diameter to eliminate bottlenecks and maximize airflow. The kit includes new CFD-tested hoses for all four positions, with turbocharger outlet hoses made from high-temperature-resistant material, rated for continuous use at 240°C.

Y-Pipe

• The do88 Y-pipe is the result of meticulous design, incorporating extensive CAD modeling, flow calculations, and 3D prototyping. Engineered for high-performance applications, it eliminates system restrictions while delivering significantly improved airflow and maintaining a lightweight construction. Crafted from mandrel-bent aluminum pipes, the Y-pipe features a 3D free-form designed cast collector to optimize flow. Finished with a durable and elegant powder coating, the do88 Y-pipe combines exceptional performance with a sleek appearance.

Testing

• The diagram illustrates the performance difference between the OEM 996 intercoolers and the do88 Performance Intercoolers. Data was recorded using an AIM race logger during three consecutive full-throttle acceleration runs from 50 to 250 km/h in a Stage 1 tuned Porsche 996, with no cooling between runs. Initial tests were conducted with the OEM intercoolers, followed by a quick swap to the do88 intercoolers, and the same test sequence was repeated. The results show a significant improvement in cooling, with a peak intake air temperature reduction of 41°C. Extensive development, including end tank refinement and optimized cell package selection, has resulted in intercoolers that excel in both heat transfer and airflow efficiency. Airflow performance was validated using the Superflow SF-1020 Probench as a complete system with hoses on both the inlet and outlet for accurate comparisons between the OEM and do88 intercoolers.
