Description
Description
This kit comes in at a package price and includes our motorsport grade intercooler and high flow y-pipe with all hoses and accessories for installation. To even further enable a better breathing engine, our norm-setting inlet ducts can be purchased alongside these products.
The intercooler kit MERA and the y-pipe are great products on their own. Used together they generate a great inlet temperature reduction, less backpressure throughout the whole system and thereby allowing more power.
- Colder inlet air temperature in the same conditions: 37°C/98,6 F (55°C/131 F), 18°C/32,4 F lower. See diagram under product pictures.
- More air to your engine, less backpressure and better airflow!
- Airflow at 0,175 bar / 2,54 psi pressure drop: 835 CFM (607 CFM), 37% higher! See diagram under product pictures.
- Top-quality, high-density motorsport-grade, Bar&Plate cores from Garrett.
- 3D freeform designed cast end tanks.
- Custom designed carbon fiber ambient air guides.
- Y-pipe made of 2,5" (63mm) mandrel bent aluminum pipes.
- Y-pipe made from a cast, smooth flowing collector part.
- Y-pipe has two methanol injection connections (1/8 -27 NPT). The pipe is delivered with blanking plugs in these connections.
- Comes with high quality silicone hoses and accessories for installation.
About the intercoolers:
MERA as in more, means more cooling, better airflow, more performance. Simply, MERA!
Upon launching this intercooler kit back in 2018, we chose to go with a Tube&fin core, enabling great cooling and airflow paired with a low weight. It has proved very well over the years, featured on various 1000 HP builds. In the spring of 2022, it´s time for the next phase in the constant development of do88 products. After thorough testing, we chose to move over to a Bar&Plate, motorsport-grade core from Garrett, thus bringing this already highly effective upgrade to the next level.
Differences to our previous version:
- 13% higher airflow compared to our previous version.
- New, lighter airduct made from real prepreg carbon.
- 3,1 kg weight increase per intercooler compared to the previous do88 intercoolers.
All in all, the weight increase compared to the OEM units is relatively small considering the sheer size of the intercoolers, and the fact that it´s an all-aluminum, dense construction. Our intercooler weight is 8,5 kg (18,74 lbs) per piece and the 991 OEM intercooler weighs 3,10 kg (6,83 lb) per piece. As much as it may seem in terms of weight increase, it is more than well compensated for if we consider the performance gain these intercoolers provide!
About the Y-pipe:
In the beginning of the development process of this product we spent a lot of time thinking what would be the preferred way to build a Y-pipe and here is the result of our conclusions and development process! Our pipe have both a very good flow rate and a low weight which is accommodated by composing mandrel bent lightweight pipes with a high quality 3D freeform designed cast joint between them. Onto the cast part we then welded CNC-machined connections for bov and breather hoses.
This construction adds a lot of performance but only a tad of extra weight.
Performance:
When it comes down to performance, the do88 bigpack significantly reduce the intake temperature! In the graph below the difference towards the OEM 991 units is presented. The data is collected with an AIM race logger under 5 consecutive runs in an immediate sequence. Full throttle accelerations between 50-250 km/h (30-155 mph) in a Stage 1 tuned Porsche 991. No cooldown in between, just full pull. During every test, the car was driven in Sport Plus, AC off.
The test was conducted in the following manner:
Firstly, 5 runs were made with the car equipped with OEM intercoolers. Stop, fast change of parts to the do88 intercoolers. Shakedown for a few minutes and then 5 runs made in the exact same way as with the OEM parts. The decrease in inlet air temperature is significant, peak delta is 17°C (30,6 F) !
Cooling is important, and so is airflow. After many hours in the development, refining the end tanks and choosing a core to meet our demand, the result is an intercooler that is much more efficient in terms of heat transfer as well as 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 991 units. What you see is what you get – true performance!
