Dual wastegate, advantage and disadvantage

Under braking the MGU-H converts to a motor to keep the rotational speed of the turbocharger high enough to avoid the curse of the turbo engine – turbo lag. This is a phenomenon experienced under braking when the turbocharger speed slows as a lower volume of gas is produced.

It does both K, as Micky points out. Another good explanation here:

But what if the wastegate pipes were seperate almost to the gate valve. Like siamesed. Then the gasses/pressurewaves have little chance of reversion and interfering with the other chambers.
Or you could have a tuned length on the gate merge so the reversion pulse has a extractor effect.

But, also consider this whole part of the system is under pressure and these gasses will have some inertia to them

I know this is an old subject BUT FYI / FWIW my TS manifold single WG is fed from both sides via a single pipe that has a central divider that keeps the pulses seperate till the gate..
