Porsche 911 Turbo 991 MERA intercooler kit do88

With this intercooler kit with extreme cooling performance, the performance of the 991 will be improved significantly!

The intercoolers feature cast end tanks that distribute the airflow very precisely across the entire core. This is very important, as good tank design is beneficial for both pressure drop and cooling performance. In order to be able to install an intercooler with suitable thickness, it was also necessary to design a new upper ambient air guide. This was designed in our 3D-scanned environment to ensure a perfect fit to the vehicle-integrated air ducts as well as to the intercooler.

To eliminate further bottlenecks, the intercooler kit has MERA intercooler connections that are 70 mm wide to really allow the air to flow through without restrictions. All hoses are CFD-tested. To truly make full use of all the benefits of the heat-transferring ambient air, the carbon ducts are supplied with matching seals to the cooler, forcing the air to flow through the core.

When it comes to performance, the do88 intercoolers significantly reduce intake temperature! The diagram shows the difference compared to the OEM 991 coolers. The data is collected with an AIM race logger over 5 consecutive runs in direct sequence. Full-throttle accelerations between 50–250 km/h (30–155 mph) in a stage 1 tuned Porsche 991. No cool-down in between, just full throttle. In every test the car was driven in Sport Plus mode, AC off.

Features:

• Colder intake air temperature under the same conditions: almost 20 degrees lower
• More air for the engine, less backpressure and better airflow
• Airflow up to 19% higher
• 3D, freeform-designed cast end tanks
• Individually designed carbon fiber ambient air guides
  
• complete kit with silicone hoses and hose clamps
