Enhance your B58 engine's performance with the MERA do88 Charge Cooler Manifold!
Background
The B58 engine, introduced with the F-series, 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 direct injection system is not well suited for high horsepower applications or ethanol flex fuel usage. Port fuel injector spacers can position injectors at an awkward angle, leading to 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
This performance charge cooler is part of our MERA range! MERA means more cooling, better airflow, more performance. Simply, MERA!
