do88 nagy intercooler készlet
Ezekhez a változatokhoz jó:
Porsche 911 (991.1) - 2013-2015 - minden Turbo változat (első generáció)
A true performance upgrade intercooler for the 991 Turbo / Turbo S.
This is the most refined of all products we carry today!- Significantly improved Air flow! (see diagram below).
- Cooler air to your engine! (see diagram below).
- High quality high density UK made motorsport cores.
- 3D freeform designed cast end tanks
- Custom designed carbon fiber ambient air guides.
- Comes with high quality silicone hoses and accessories for installation.
Already from the beginning we realized that 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 made a lot of investigation and comparisons between different core types and at last really fell for a high density motorsport core which have great cooling efficiency among with a low 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 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 are to use 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 this way to build our intercoolers the weight increase compared to the OEM ones was relatively small considering the size of our intercooler and that its all made of aluminium. Our intercooler weight is 5,4 kg (11,9 lb) per piece and the 991 OEM intercooler weights 3,1 kg (6,8 lb) per piece. It might sound like a big weight increase but compared to other actors on the market with intercoolers in this size it's a low weight!
We sell this intercooler kit in two different versions, one that fits with the OEM Y-Pipe and one version that fits our performance Y-Pipe. The difference is which intercooler outlet hoses we supply. You can make your choice in the drop list above.
At the same time as our intercoolers lowers the intake temperature they also flow better than the 991 original intercoolers! Please have a look at the air flow rates at different pressure drops in the graph below where we compared our intercooler with hoses to the original intercooler with hoses in our own Superflow SF-1020 Probench to verify the final result!
Keep in mind that the OEM intercoolers was designed for the power level the car was built for originally. A power increase may cause your stock intercoolers to not be efficient enough. So even on an engine with a software tune or using your car in hot climate the do88 performance intercooler kit will give a performance increase over the OEM intercoolers!
do88 performance intercooler kit comes as a complete package with all parts necessary for installation.
