Twomodified4u's Turbo S2000 Build

yeah math was off, lol its 76mm total. and where did you get 53mm? I didnt know they make 26.5MM wastegates.

Yes just like my first reply. Divided manifold NEEDS 2 wastegates. No way around that. Has zero to do with boost controll efficiency. If you have a divided manifold, the group of cylinders are completely seperate, usually paired to hit the turbo based on stroke timing.

Yeah never said it didnt. JSE’s question was far to vauge to give an accurate answer, as your answer was missing key facts to answer the question also. Your answer is completely valid if the person asking the question knew the difference between a divided manifold/turbo vs single source of exhaust gasses hitting the turbo all together.

They are two completely different reasons for running 2 wastegates, to be completely accurate with a response.
