50mm external wastegate. Combining a compact body, superior flow path and high temperature resistance makes the Pro-Gate50 a market leader in its sector. Shielded diaphragm housing ensures excellent heat handling capabilities.
The most common reason for investing in an external wastegate is fitting an after-market turbo or better control of the boost and consequently the power output of your engine. Additionally, most large frame turbochargers are not equipped with internal wastegate systems. Most tuners will recommend an external wastegate for any engine producing 400hp or more.
