I was wondering how would one get a set-up with a twin scroll turbo and, twin scroll manifold to work with a single external wastegate? (if possible)

Hi,
to get the full advantage of twin scroll you have to split the exhaust pulses until the turbo is passed by, but i think i know what you want to do i think you will get a non-equal chamber filling if you just bypass the two equal exhaust pulses greetz -------------------- KEEP COOL UNDER PRESSURE

As has been said you cant have it in a perfect setup, but 1 runner from each side, then joining up before the gate would be the best bet, but in this configuration gas could move from one side to the other.
