The Granatelli 60mm wastegate features a traditional diaphragm-style actuator and a larger 60mm valve for higher-flow boost control in turbocharged systems. It’s intended for setups needing increased exhaust bypass capacity to manage higher boost levels or larger turbochargers. The 60mm size helps maintain stable boost control without resorting to extensive header or turbine modifications.
