Innovatively designed cast end tanks The charge air and cooling water are evenly distributed across the core through carefully designed, cast end tanks. The development of these end tanks involved a comprehensive process, including 3D-scanning, multiple design iterations followed by Computational Fluid Dynamics (CFD) analysis and 3D-printing, before arriving at the finalized prototype. We opted for cast end tanks over CNC-machining. Casting allows complex shapes that better serves the desired function. To us, maximum performance supersedes the bling factor!

Engine Cover Compatibility A key objective during the development of our do88 Charge Air Cooler, was ensuring its compatibility with the standard engine cover. It goes without saying, enthusiasts prefer to maintain the original appearance of their engine bay if possible. With this in mind, we invested significant effort to design a charge air cooler that not only makes a massive performance upgrade, but also fits beneath the engine cover. We even managed the challenging task of accommodating our auxiliary fuel rail under the engine cover. The devil is in the detail and to date, this unique feature sets the do88 kit apart from the competition. High performance builds tend to be made by enthusiasts that value the appearance equally as high as the sheer performance without compromise.

Key Features Versatile Manifold Design: From Fuel Injection to Power Modifications Our manifold outlet tank is pre-configured to accommodate auxiliary port fuel injection. A custom-made fuel rail with female AN-8 threads is included, which easily installs to the outlet tank. We designed it for compatibility with Injector Dynamics ID1050x-34-14 (ID1050x-34-14-14) or Bosch EV14 Compact (K) fuel injectors. If you opt to not use port fuel injection, we provide injector blanking plugs for your convenience. Additionally, each cylinder runner on the outlet tank is equipped with a 1/8” NPT port, suitable for nitrous or methanol injection - a commonly used power modification for the B58 engine (sealing plugs are included).

Extra Measurement & Vacuum Ports Integrated into the side of the manifold inlet tank, do88 has incorporated a 3-port pad directly into the casting. This feature offers the flexibility to measure additional parameters or serve as an extra vacuum source. Should you choose not to utilize these three 1/8” NPT ports, sealing plugs are provided in the included hardware kit. Two 1/8” BSPT ports are strategically positioned on the top of the rear water tank. These ports serve dual functions. They can be used for monitoring both inlet and outlet water temperatures, but also act as bleeding ports to assist in the air-bleeding process, ensuring that all air is effectively purged from the intake manifold. For your convenience, 1/8” BSPT plugs are provided in the included hardware kit. Advanced Thermal Management Included with the intake manifold is a special thermal barrier spacer, engineered to insulate the aluminum intake manifold from conductive heat transfer from the cylinder head. This barrier effectively lowers intake air temperatures (IAT´s), enhances the efficiency of the charge air cooler, and helps minimize the issue of heat soak. Unlike the OE plastic intake manifold, the do88 manifold is made from aluminum, capable of withstanding higher boost pressures. The thermal barrier spacer reduces the conductive heat transfer, otherwise typical to aluminum components. The spacer features a robust seal, achieved through custom-made, high-specification FKM-silicone O-rings. These O-rings are installed in precision-machined grooves for a secure fit. This approach offers a significantly better seal compared to other competitors´ methods, which often rely on less reliable sealing agents.

Included Plugs and Caps for Manifold Customization Should you wish to seal off the crankcase vacuum connection on the manifold outlet tank, a plug is included specifically for this purpose. Additionally, a cap is provided to close off the fuel tank breather line connection on the manifold inlet tank. These ports are commonly blocked for higher outputs, so we include these.
