Below you see 3 boost curves. First we start with just a hypothetical chip. The next two show two different ways of adding an MBC to the system and how they affect this chip's boost curve.
The N75 Only shows a hypothetical boost curve with a chip and your standard N75 valve in place.
The N75 & MBC in Parallel shows the MBC set at ~17psi, such that any boost above that will get bled off by the MBC, but the N75 will still control the boost curve below the MBC's set limit.
- Here the MBC functions to remove spikes.
- In this configuration, the MBC is only capable of reducing boost lower than what would occur without it.
The MBC Only shows the MBC set at ~17psi, such that the MBC has complete control over the boost.
- Here the MBC functions to control the boost.
- In this configuration, the MBC has full control, and can either raise or lower boost, and thus caution is suggested when doing this. One should have knowledge of fueling limitations, turbo capabilities, etc.
