Big Pack Porsche 911 Turbo (997.2)

The complete performance package for both high flow and cold air for Porsche 997.2 Turbo / Turbo S

About Our Intercoolers

To truly distribute the flow across the entire core, we use cast, flow-verified end tanks. A well-designed end tank shape is crucial to fully utilize the heat transfer properties and to maximize flow. Flow and cooling are also directly dependent on the core's size, and to enable the use of the thickest possible core, the upper air ducts are replaced with carbon fiber ducts, designed by do88 based on 3D scanning. This ensures a perfect fit against both the car's structure and our larger intercoolers. To maximize the effects of heat transfer, these air ducts are supplied with proper sealing strips against both the intercooler and the chassis, so that the cooling air does not take the easiest path past the core. The connections on the intercooler are a full 70 mm to maximize flow and eliminate bottlenecks in the system. This means that this kit comes with new hoses in all four positions, all designed and CFD-tested for optimal flow. The hoses on the turbocharger outlet are made of material with particularly high heat resistance, rated for a continuous temperature of 240°C. Overall, the weight increase is relatively low given the intercoolers' size, density, and the fact that they are made entirely of aluminum. They weigh 8.45 kg per side compared to 3.3 kg for the original 997.2 intercooler. This is certainly an increase, but it is more than justified considering the performance upgrade this kit provides!

About Our Y-Pipe

This is the result of in-depth research, countless hours at the drawing board in CAD, and numerous 3D visualizations and 3D prints. do88's Y-pipe is the answer when you have high power goals and truly want to remove restrictions in the system. It offers significantly improved flow along with low weight! The Y-pipe is made of mandrel-bent lightweight aluminum tubes welded to a 3D free-form designed, cast collector to maximize flow. On this part, there are CNC-machined and then welded connections for the dump valve and crankcase ventilation. This construction offers a significant performance boost with only a marginal increase in weight. do88's Y-pipe weighs 1.52 kg, while the Porsche OEM plastic Y-pipe weighs 1.38 kg. A well-known competitor weighs in at 2.76 kg. As a final step, the Y-pipe is coated with an exclusive powder coat that makes it look as good as it performs. Choose between a discreet semi-gloss black finish or a fresh silver metallic!

Performance

Regarding performance, do88's BigPack provides a significant reduction in intake temperature! The graph below shows the difference compared to 997.2 OEM. All data was collected with our AIM racelogger during five consecutive runs. Full throttle acceleration from 50-250 km/h in a Porsche 997 with Stage 1 software. No cooling between runs, just full throttle! During all runs, the AC was off, Sport Plus activated. The tests were performed as follows: First, five runs were made with OEM 997.2 intercoolers installed. Stop, quick part change on site. A few minutes of test driving and then five runs with do88 intercoolers in exactly the same way as with OEM a few minutes earlier. The temperature drop is striking, a maximum difference of 18°C, see the graph below. Cooling is important, but so is flow. After many hours at the drawing board, refining the end tanks combined with a core to meet our requirements, we have a result that speaks for itself. The do88 MERA intercooler kit is much more efficient in both heat transfer and flow. With our own Superflow SF-1020 Probench, we have verified the flow as a complete system, with hoses and pipes for both the do88 BigPack and OEM 997. What you see is what you get – true performance!
