Performance intercooler upgrade kit.



To Fit:
Porsche 911 997.1 Turbo 2007-2009 and GT2RS models

A true performance upgrade intercooler kit for the 997.1 Turbo and GT2. This well thought out refined kit allows fitment of the larger later type 997.2 intercoolers onto the 997.1 model, and includes all the components and hardware necessary for a serious upgrade!

Significant advantages with Do88's Porsche Performance Intercooler Kit:

• Cooler air to your engine!
• High quality, high density UK made motorsport cores.
• 3D freeform designed cast end tanks.
• Custom designed carbon fibre ambient air guides.
• Comes with high quality silicone hoses and accessories for installation.
• See enlarged images for more information!

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 optimise 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!

Included in this kit:

• Performance intercoolers
• Carbon fibre air guides
• Silicone hoses
• Hose clamps
• Rubber seals
• Installation hardware

When it comes to performance our intercooler kit gives a great reduction of the intake temperature compared to the OEM 997.2 intercoolers! See enlarged diagrams where we show data from our AIM racelogger recorded at 5 full throttle accelerations done in an immediate sequence without any cool down between 40-260 km/h (25-162 mph) in a Stage 1 tuned Porsche 997.2 Turbo PDK. In all tests the car was driven in Sport Plus, automatic gear change and AC off. First we made 5 runs with the car equipped with OEM intercooler and y-pipe then we switched to do88 performance intercoolers and y-pipe and drove car for a while, then we made 5 runs exactly the same as with the OEM parts. The temperatures are significant lower with our intercoolers which is visible in the graph!

As well as lower intake temperature our big pack also flows better than the 997.2 original intercoolers! See enlarged image showing the air flow rates at different pressure drops in the graph where we compared our big pack to the original intercooler and Y-pipe in our own Superflow SF-1020 Probench to verify the final result!

From our five in a row full throttle accelerations between 40-260 km/h (25-162 mph) we have very accurate and consistent test data for the range 50-250 km/h (31-155 mph). When analyzing the numbers, we found that in average we cut down the acceleration time for 50-250 km/h (31-155 mph) by 3 seconds compared to the OEM intercooler and y-pipe! No software programming or adaption reset was done in between the tests.

Significant advantages with do88's Porsche Performance Intercoolers & Silicone Hoses:

• Equivalent OEM numbers, 997.110.639.00, 997.110.640.00 (ref only)
• Core Volume: 6825 cm³ (4821 cm³), do88 41% larger!
• Lower post Intercooler Air Temperature at same conditions: OEM 50°C (122°F), do88 34°C (93°F)
• See enlarged images for test data results!

These Intercoolers are constructed to deliver the best cooling efficiency during tough conditions. Exclusively manufactured in aluminium with continuous welds, they guarantees reliability and endurance when you really need it. The increased core volume improves cooling efficiency and lowers the intake air temperature. Do88 have undergone thorough testing under severe and continuous conditions to ensure the absolute best performance! These Intercoolers are immensely optimized to allow the maximum core size in the given space without compromising on easy drop-in-fitment. This is the undoubted choice for the inspired enthusiast or the race car driver demanding reliability at the limit.

This package is supplied with everything you need for fitment, including Silicone Hoses, Screws, Brackets and Clamps.

The Boost Pressure Hoses included in this Kit are Silicone reinforced 4 ply polyester fabric for optimum airflow, performance and reliability!

Turbo benefits from Hybrid Turbos own design billet aluminium compressor wheel. Not only does billet offer significantly improved strength and durability over the original cast aluminium wheels if used correctly the material can be used to make the wheel lighter. A lighter compressor wheel will spool quicker allowing for better response from the turbocharger meaning a reduction in turbo lag. The billet aluminium compressor wheels are upto 20% lighter than the originally used cast items.
