Description
The Turbosmart IWG75 BW B1 Twin Scroll 14 PSI is a high-performance internal wastegate actuator designed specifically for factory frame turbochargers. This actuator is engineered to optimize boost response and overall efficiency, making it ideal for automotive enthusiasts looking to enhance their forced induction setups.
- Proprietary Silicon Nomex diaphragm for superior durability and performance
- Increased effective surface area for improved working ratio compared to factory actuators
- High-grade billet aluminum construction ensures lightweight strength
- Stainless steel rods and clevis for enhanced reliability and longevity
- Turbosmart’s unique locking collar system for secure adjustments
- Available spring options ranging from 3 PSI to 26 PSI to suit various tuning requirements
The IWG75 actuator allows tuners to achieve a broader boost and torque curve, reaching peak boost earlier in the RPM band and maintaining it longer. This is particularly beneficial for high-boost builds, road course applications, and time attack scenarios.
Constructed from premium materials, the actuator is designed for long-term performance. Regular maintenance involves checking for wear and ensuring that the locking collar remains secure. Tuning and recalibration may be required when adjusting base pressures to maximize performance.
