• Upgrade Your Turbo with Turbosmart! These wastegate actuators are engineered to deliver maximum boost response for your factory frame turbocharger. • Key Benefits: Enjoy an increased 'Working Ratio' over factory equipment, leading to better boost response across all RPM ranges. • Twin Port Advantage: Twin Port Actuators offer a wider tuning window and greater boost control options. With the same base pressure as the factory, you'll get a broader boost and torque curve. Higher base pressures can amplify these improvements, though tuning may be required. Features include a proprietary Silicon Nomex Diaphragm, a choice of springs from 3psi to 26psi, high - grade billet aluminum construction, stainless steel rods and clevis, and Turbosmart's unique locking collar system.
