Interesting but the plate is a restriction even in closed position.

Exactly what I was thinking! That is alot of heat in there!

Creamo3, concept is pretty simple. Use an undivided manifold, twin scroll turbo. All of the exhaust is directed through half of the manifold which means increased exhaust velocity making the turbo spool quicker. The valve opens at certain a certain pressure and increases flow at high RPM.
They do in fact work, Ive seen them on the dyno. I saw one that on a bigger turbo, spool was about 5-600 RPM better than non valved.

Chris/Larry have done testing, it spools a LARGE turbo supra apparently ~500rpms quicker, its all about velocity.

It'll theoretically "spool" the turbo a little better than a twin scroll manifold would, because you're technically turing the turbine housing into one half it's normal size. Once spooled, however, a proper twin scroll manifold would have the advantage by properly pulsing the exhaust. Add in the possiblity of the blade/shaft seizing up or breaking off, and I'll stick to a real twin scroll setup any day.

The 64 million dollar question is. would it spool faster than twin scroll mani feeding a twin scroll turbine housing. That would be an interesting test. I wonder if anyone has done this type of testing on it.
