I stand corrected. I've personally been N/A since 2005 when I got rid of my Evo 8 that was pushing well over 600AWHP on a stock twin scroll "Big 16G" turbo. Only mod to turbo was the bigger 10.5 hotside from the evo 9 and some machining of the cold side.
I was always under the impression that single scrolls used ind cylinder manifold engineering and the engines natural exhaust pulse rate to ensure no two cylinders tried pushing exhaust through the hot side simultaneously. Thinking about it more thoroughly, that would hypothetically be possible in a 4 cyl like the Evos 4G63 but in a 6 cylinder, 2 cylinders would naturally have to be on the exhaust stroke at the same time at some point.
While I understood Twin Scrolls had two inlets, i just thought that the entire hotside was basically split into two sections with two smaller impellar wheels.
Thanks for the info and the article. I read it in it's entirety. I'm just getting back into pulling power out of a f/i engine.. Your post and the article were very educational and helpful.
