DO88 Porsche 997.1 Turbo Full Big Pack including Inlet Hoses

Complete Performance Charge Air High Flow Cooling Kit with Inlet Pipes

To Fit: Porsche 911 (997.1 Turbo) 2007-2009

This complete package includes Do88's motorsport grade intercooler package with carbon fibre air guides, high flow Y-pipe with all hoses and accessories for installation and the optional high flow inlet hoses.

The intercooler and y-pipe are great products individually but as a team they give great reduction of inlet air temperatures and at the same time they reduce the back pressure of the whole system; this means increased power!

Significant advantages with Do88's Porsche Performance Charge Air High Flow Kit:

• Cooler air to your engine! 38°C (52°C), do88 14°C lower than OEM parts!
• High quality high density UK made motorsport cores
• 3D freeform designed cast end tanks
• Custom designed carbon fibre ambient air guides
• Assembly air flow at 0,175bar/2,54psi pressure drop: 646CFM (564CFM), do88 15% higher!
• Post intercooler air temperature at same conditions: 38°C (52°C), do88 14°C lower!
• Y-pipe made of 70mm mandrel bent aluminium pipes
• Y-pipe smooth flow cast collector part
• Comes with high quality silicone hoses and accessories for installation
• See enlarged images for more information!

About the Intercoolers:

Do88: After our market research in the beginning of our intercooler development for the 997 generation 2 we understood that not many of the upgrade products on the market are really upgrades but more at the same level as the 997.2 standard intercoolers or sometimes even lower. For this reason we realised from the beginning we could not sacrifice anything to keep the cost down, we just had to do the best possible in the space available in the car!

First of all we carried out a lot of investigation and comparisons between different core types and at last really fell for a high density motorsport core which has great cooling efficiency as well as being light weight. With a great core in place we started to refine the end tank design which brought us to a decision to make cast end tanks as we could then control the air flow distribution over the core in a very precise way. This is very important as a good tank design will be beneficial for both pressure drop and cooling efficiency.

To be able to fit an intercooler with appropriate thickness for the job it was also necessary to design a new upper ambient air guide. This was designed in our 3D scanned environment from carbon fibre to ensure perfect fit to the vehicle integrated air guides and our intercooler. To achieve the best air flow distribution over the core we made intercooler end tanks with 70 mm (2 3/4 inch) connections which then made it necessary to designed custom silicone hoses for all positions.

The hoses are 3D designed with airflow in mind where we CFD tested each hose during development to ensure best possible flow rate of all parts! The hoses between turbocharger and intercooler are special silicone hoses that can withstand up to 240°C (464°F) continuous temperature! Another important aspect for cooling performance is to maximise all ambient cooling air available, to optimize this part we include air block rubber seals for all surfaces where the ambient air guides must seal properly.

With the way we have chosen to build our intercoolers the weight increase compared to the OEM ones is relatively small considering the size of our intercooler and that it's completely made of aluminium. Our intercooler weight is 5,85 kg (12,89 lb) per piece and the 997.2 OEM intercooler weights 3,30 kg (7,27 lb) per piece. It might sound like a big weight increase but not when you compare it to similar core sized intercoolers on the market!
