The complete charge air cooling solution for the Porsche 997.1 Turbo / GT2!
This all-in-one kit includes our motorsport-quality intercooler and high-flow Y-pipe with all hoses and installation hardware. To further improve engine performance, our compliant intake manifolds can be purchased with these products.
The MERA intercooler kit and Y-pipe are excellent products on their own. Used together, they significantly reduce inlet temperature, resulting in lower backpressure throughout the system, and thus increased power.
– Cooler inlet air temperature under the same conditions: 37°C/98.6°F (55°C/131°F), 18°C/32.4°F lower. See diagram below the product images.
– More air to the engine, lower backpressure, and improved airflow!
– Airflow at 0.175 bar/2.54 psi pressure drop: 771 CFM (564 CFM), 37% more! See diagram below product images.
– Premium, high-density motorsports Bar & Plate cores from Garrett.
– 3D freeform cast end tanks.
– Custom carbon fiber ambient air guides. – Y-pipe constructed from 2.75″ (70mm) mandrel-bent aluminum tubing.
– Y-pipe constructed from a cast, flowable manifold section.
– Supplied with high-quality silicone hoses and installation hardware.
About Intercoolers:
MERA, as in more, means more cooling, better airflow, more performance. Simply put, MERA!
When launching this intercooler kit in 2016, we chose to use a Tube & Fin core, which provides excellent cooling and airflow combined with reduced weight. It has proven itself very well over the years, featured on various 1,000 HP builds. In the fall of 2021, it’s time for the next phase in the ongoing development of do88 products. After extensive testing, we’ve chosen to upgrade to a motorsport-quality Bar & Plate core from Garrett, thus taking this already highly effective upgrade to the next level.
Differences from our previous version:
11°C lower IAT than our previous version.
19% higher airflow than our previous version.
New, lighter air duct made of real prepreg carbon.
3 kg weight increase per intercooler compared to previous do88 intercoolers.
The core is new, but the end tanks and all accessories are the same as before. The intercoolers feature cast end tanks that distribute airflow very precisely across the entire core. This is very important since a good tank design will benefit both pressure drop and cooling efficiency. To fit an intercooler with the appropriate thickness for the job, a new upper ambient air guide also had to be designed. This was designed in our 3D scanned environment to ensure a perfect fit with the air guides integrated into the vehicle, as well as the intercooler. To further eliminate bottlenecks, the intercooler connections are 70 mm (2 3/4″) inches) to truly allow air to flow unrestricted. This also means new hoses are included for each location, all 3D-designed with maximum airflow in mind. All hoses are CFD-tested to ensure this. The turbo outlet hoses are made from a high-temperature material, rated for a continuous temperature of 240°C (464°F). To truly harness all the heat it transfers from the ambient air, the carbon ducts are fitted with proper seals to the body, forcing all air to pass through the core and not leak around it.
All in all, the weight increase over the OEM units is relatively small considering the size of the intercoolers and the fact that they are a dense, all-aluminum construction. Our intercooler weighs 8.45 kg (18.10 lbs) per piece, and the OEM 997.2 intercooler weighs 3.30 kg (7.27 lbs) per piece. As much as this may seem in terms of weight gain, it is more Which is well worth it considering the performance gains these intercoolers provide!
About the Y-Pipe:
We present the result of extensive research, many hours at the drawing board, and numerous 3D visualizations and 3D prints. The do88 Y-Pipe is the ideal solution for larger numbers when you want to eliminate all system restrictions, offering very good airflow combined with low weight! The Y-Pipe is made of lightweight mandrel-bent tubing with a high-quality 3D-designed cast joint between them. The cast manifold features NC-machined connections for the BOV and vent hoses.
This construction adds a lot of performance but only a hint of extra weight. The do88 high-performance Y-Pipe weighs 1.52 kg (3.35 lbs), the OEM plastic tube weighs 1.38 kg (3.04 lbs), and a competitor’s cast performance tube comes in at 2.76 kg (6.08 lbs)!
As a finishing touch, the Y-Pipe is rounded off with a High-quality powder coating that makes it look as good as it performs! You can choose between the more subtle semi-gloss black and a new metallic silver finish.
Performance:
When it comes to performance, the do88 bigpack significantly reduces intake temperature! The graph below shows the difference compared to the OEM 997.2 units.
The data is collected with an AIM race logger in 5 consecutive runs in an immediate sequence. Full-throttle accelerations between 50-250 km/h (30-155 mph) in a Stage 1-tuned Porsche 997. No cooling in between, only full traction. During each test, the car was driven in Sport Plus with the AC off.
The test was conducted as follows:
First, 5 runs were performed with the car equipped with the OEM intercooler. Stop, quick parts swap with the do88 intercoolers. Shakedown for a few minutes, and then 5 runs performed exactly the same way as with the OEM parts. The decrease in intake air temperature was Significantly, the peak delta is 18°C (32.4°F), see the graph below!
Cooling is important, as is airflow. After many hours of development, refining the final tanks, and choosing a core to meet our requirements, the result is a much more efficient intercooler in terms of heat transfer and airflow. Using our in-house Superflow SF-1020 Probench, the airflow is verified as a complete system with both intercoolers, hoses, and Y-pipe for both the DO88 bigpack and the OEM 997 units. What you see is what you get: true performance!
