The advantage of the External Wastegate is to help the turbocharger operate more efficiently. This is done by relieving a large amount of back pressure pre-turbine housing. Less restrictive turbine housing will allow you to run higher boost pressures which typically results in more horsepower and even the ability to run higher ignition advance if needed. It is common to see a 15 hp to 30 hp gain when going from Internal Wastegate to External Wastegate setups. When boost is held flatter throughout the rpm band, the result is higher horsepower numbers at less peak boost pressure vs. the Internal Wastegate.
