BLOX Racing offers a manual boost controller that rivals its electronic
counterparts. Each controller is constructed out of billet aluminum
and stainless steel components, and features a boost dial that is easy
to adjust yet will not slip causing over boost conditions. Incorporated
into the design is a lightweight ceramic ball that is more sensitive
and reacts quicker during boost operation. The ceramic ball also
contributes to fine and consistent boost pressure adjustments.
Also included with the MBC are two additional pressure springs that can
be changed for different requirements; a light and heavy duty spring.
The light spring is ideal for lower boost requirements and when fine
control of boost pressure levels is required. The heavy-duty spring is
ideal for high boost pressure requirements.
