Enhance your B58 engine's performance with the do88 Charge Cooler Manifold!
Background
The B58 engine, introduced with the F-series a few years back, has proven to be a real gem of an engine, capable of high outputs with great character. However, there are a few weak points that need addressing, both for performance and reliability. The B58 comes equipped with a water-to-air charge cooler that is coupled with a front-positioned heat exchanger (water radiator). The heat exchanger serves to cool the water circulating through the charge air cooler, which in turn helps dissipate heat from the charge air before it enters the engine. The charge air cooler is integrated into the intake manifold on the B58, making it an intricate and dense construction, demanding accuracy in the design and execution by us as an aftermarket producer.
Challenges with the factory components
Owners of tuned B58 engines often confront the issue of rapid heat soak in the charge air cooling system, particularly when the vehicle is used for track days. Elevated intake air temperatures may prompt the ECU to decrease the power output, or even switch the car into limp-home mode. Regular spirited street driving can also cause similar issues.
Additionally, the factory installed direct injection system, with its obvious benefits, is not well suited for high horsepower applications or ethanol flex fuel usage. Port fuel injector spacers can position injectors at an awkward angle, causing potential fuel puddling. The factory OE intake manifold restricts airflow and poses a risk of cracking under high boost levels due to its plastic construction.
The do88 solution
Bar&Plate core
Our manifold features a Bar&Plate design air-water core, with densely stacked cooling fins for optimal heat transfer. The core is 102 mm (4 inches) thick, maximizing its effectiveness. Both the air and water fins have been carefully evaluated to balance cooling and airflow.
Innovatively designed cast end tanks
The charge air and cooling water are evenly distributed across the core through cast end tanks. Development included 3D scanning, multiple iterations, CFD analysis, and 3D-printing of prototypes. Casting allows complex shapes that better serve function over appearance.
Engine Cover Compatibility
Designed to fit under the standard engine cover. Auxiliary fuel rail can be accommodated under the engine cover. This unique feature sets the do88 kit apart from the competition, allowing high performance without compromising engine bay aesthetics.
Intercooler Features:
Versatile Manifold Design: From Fuel Injection to Power Modifications
Manifold outlet tank pre-configured for auxiliary port fuel injection. Optional fuel rail (purchased separately) fits Injector Dynamics ID1050x-34-14 or Bosch EV14 Compact (K). Injector blanking plugs included. Each cylinder runner has a 1/8" NPT port for nitrous or methanol injection (plugs included).
Extra Measurement & Vacuum Ports
Integrated 3-port pad on inlet tank for additional measurements or vacuum. Plugs included. Two 1/8" BSPT ports on top of the rear water tank for inlet/outlet water monitoring or air-bleeding. Plugs included.
Advanced Thermal Management
Thermal barrier spacer included to reduce conductive heat transfer from cylinder head. Aluminum manifold capable of higher boost pressures. FKM-silicone O-rings provide superior sealing.
