Garrett external wastegates regulate turbocharger shaft speed by venting exhaust gas around the turbine stage of the turbocharger. CFD optimized design maximizes flow and delivers optimum boost control. Advanced termal optimization increases durability of the diaphram. The cap design makes spring changes and serviceability of the entire Garrett lineup easier and more reliable to perform.
