The Turbosmart IWG75 Series of upgraded Actuators benefit from an increased Working Ratio over the factory equipment resulting in improved boost response, throughout the RPM range.\u003c\/p\u003e\n \u003cp\u003eThis Improved working ratio is achieved through an increase to the effective surface area of the diaphragm \u0026amp; 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. \u003c\/p\u003e\n \u003cp\u003eUpgrading with the same base pressure as factory, you can expect a broader boost \u0026amp; 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 \u0026amp; recalibration is likely required.\u003c\/p\u003e\n \u003cp\u003eTwin Port Actuators allow for a wider tuning window by plumbing a reference signal 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 for 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.\u003cbr\u003e\u003c\/p\u003e\n \u003cp\u003eFeatures\u003cbr\u003eProprietary Silicon Nomex Diaphragm\u003cbr\u003eChoice of Springs from 3psi to 26psi (Optional)\u003cbr\u003eHigh Grade Billet Aluminum Construction\u003cbr\u003eStainless Steel Rods and Clevis\u003cbr\u003eTurbosmart Unique Locking Collar System\u003c\/p\u003e\n \u003cp\u003eThis is a bolt on fitment for the Borg Warner EFR B2 Single and Twin Scroll turbocharger series.\u003c\/p\u003e\n \u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"TURBOSMART","offers":[{"title":"Default Title","offer_id":44667622424759,"sku":"TS-0620-3143","price":320.8,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2114\/4951\/files\/media_fd7aa2d4-644f-451d-a52e-2cf918699b04.jpg?v=1744587494","url":"https:\/\/whittleworks.co.nz\/products\/turbosmart-iwg-bw-efr-tp-14psi","provider":"Whittle Works","version":"1.0","type":"link"}
