Description

Part #: 24396

Under high-boost conditions, the stock actuator's weak spring allows the wastegate to blow open, limiting midrange torque. Bleed orifices (also known as "boost foolers") just make it worse. Only Banks solves this problem by replacing the boost actuator. BigHead holds the wastegate closed for quicker boost, then controls the opening to maintain peak boost for superior acceleration and mid-range pulling power. BigHead Wastegate Actuator Kit for use with 2001-2004 Chevy 6.6L. Power Now! When turbo exhaust backpressure increases, the stock actuator prematurely blows off the seat, softening boost in the midrange and killing torque. With twice the diaphragm area and spring pressure of the stock wastegate, Banks BigHead Wastegate Actuator keeps the valve seated longer and achieves a higher peak boost, sooner. At peak, BigHead opens the wastegate and holds its position, for precise boost control that gives you crisp acceleration and more mid-range pulling power. Key Features: Quick, Controlled Boost. Produces massive torque right from idle. Doubles stock's diaphragm area and spring pressure. Keeps the valve seated longer achieving higher peak boost, sooner. Crisp acceleration and more mid-range pulling power. Fits LB7 engine

  • For higher peak boost, sooner

MIA's Description

The Banks Power 24396 BigHead Wastegate Actuator is a high-performance replacement designed for the 2001-2004 GM 6.6L Duramax LB7 engine. It addresses issues caused by premature wastegate opening, which can lead to higher Exhaust Gas Temperatures (EGTs) and affect drivability.

This actuator features twice the diaphragm area and spring pressure of the stock unit. This design keeps the wastegate valve seated longer, allowing for higher peak boost to be achieved sooner, ultimately restoring lost performance and enhancing mid-range pulling power and crisp acceleration.
