Saab 9000 Manual Boost Controller + Anticipator (MBC+A)
For Saab 9000 - t-5 engines
The 9000 Manual Boost Controller + Anticipator (+A) addresses fundamental flaws in the operation of ball-spring Manual Boost Controllers.
A manual boost controller allows for higher than stock boost levels and power and a faster boost response. Most Manual Boost Controllers are now ball-spring types, as these make the turbo spool up much faster than the older ‘bleeder’ type MBCs. The only downside of the ball-spring types is that they will create boost pressure overshoots in an application where the turbo spools up very fast. And everyone wants fast boost response, so this is a common problem. A ball-spring MBC simply operates too late to regulate the boost pressure when the rate of boost response is fast.. The Saab 9000 Manual Boost Controller + Anticipator overcomes this fundamental flaw in ball-spring Manual Boost Controllers by directly compensating for what the ball-spring Manual Boost Controller cannot do. The Saab 9000 Manual Boost Controller + Anticipator applies a regulated pressure to the wastegate actuator as the boost pressure is increasing. This anticipates the actuation of the wastegate actuator. The anticipator pressure is adjusted to pre-pressurize the WGA. so when the ball-spring MBC starts to flow, its flow can get the WGA open immediately without delay.
MBC+A benefits:
No pressure overshoots; even in cold weather
Higher boost levels when pressure overshoots otherwise force lower settings
No controller induced boost pressure droop when fed from the TB (Due to the # of changes in the 9000 from year to year there is no TB tap included in this 9000 kit)
MBC+A Kit Includes:
Manual Boost Controller(MBC)
High Quality Air Pressure Regulator (APR) – 0-10psi rated
Steel Mounting plate and mounting hardware for the MBC and APR
Vacuum Hose – 2 Extension hoses with straight hose barbs for MBC to stock hose of the wastegate actuator and turbo to MBC+A, short piece of hose to plug off the BPC (to keep it clean) and hoses to connect the MBC and APR including a “wye” hose barb to connect the MBC and APR.
Zipties(cable ties) to secure the hoses to the barbs. Enough for the whole kit.
