Porsche 911 (996)
Year models: 2001-2005
Engine: Turbo / Turbo S / X50 / GT2
A true performance upgrade intercooler for your Porsche 911 (996) Turbo!
- Colder inlet air temperature in the same conditions: 25°C/77 F (66°C/151 F), 41°C/105,8 F lower. See diagram.
- More air to your engine, less backpressure and better airflow! Airflow at 0,075 bar / 1,09 psi pressure drop: 258 CFM (206 CFM), 25% higher! See diagram.
- 3D, freeform designed cast end tanks with 2 3/4" (70mm) hose connections.
- Custom designed carbon fiber ambient air guides.
- Comes with high quality silicone hoses and accessories for installation.
The intercooler kit comes with hoses adapted for OEM or do88 (63,5mm) Y-pipe. What differs is the included hoses. Choose your version in the drop-list above.
When it comes down to performance, the do88 intercoolers significantly reduce the intake temperature! In the graph the difference towards the OEM 996 units is presented. The data is collected with an AIM race logger under 3 consecutive runs in an immediate sequence. Full throttle accelerations between 50-250 km/h (30-155 mph) in a Stage 1 tuned Porsche 996. No cooldown in between, just full pull.
The test was conducted in the following manner:
Firstly, 3 runs were made with the car equipped with OEM intercoolers. Stop, fast change of parts to the do88 intercoolers. Shakedown for a few minutes and then 3 runs made in the exact same way as with the OEM parts. The decrease in inlet air temperature is significant, peak delta is 41°C (105,8 F) see the graph!
Cooling is important, and so is airflow. After many hours of development, refining the end tanks and choosing a core to meet our demand, the result is an intercooler that is much more efficient in terms of heat transfer as well as airflow. Using our in-house Superflow SF-1020 Probench, the airflow is verified as a complete system, with hoses on both inlet and outlet, for both the OEM 996 intercoolers, and the do88 performance intercoolers.
