IWG75 TP BW B2 Single/Twin Scroll 14PSISKU: TS-0620-3143
This Improved 'working ratio' is achieved through an increase to the effective surface area of the diaphragm & revisions to the actual springs fitted, resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive.
Upgrading with the same base pressure as the factory, you can expect a broader boost & torque curve through peak boost being achieved earlier in the RPM and being held longer into higher RPM. These improvements can be amplified with higher base pressures, however, tuning & recalibration is likely required.
Twin Port Actuators allow for a wider tuning window by plumbing a reference signal on either side of the diaphragm. The boost control strategy can force the pressure into the top cap for a higher 'high boost' target and, equally, force pressure under the diaphragm for a lower 'low boost' target. Twin Port Control allows greater boost control options around the base spring pressure. Often a much softer spring than usual can be used, resulting in an overall improvement in dynamics and response.
