Triple Exhaust Manifolds?
I got an Exhaust Manifold made a while back for my 20b Single turbo.
At the Time for ease i got them to make a None Divided one as i thought with the Size of the engine etc i would'nt have a problem Spooling it up (which i didn't)
Now i wish to go for a huge Turbo and to save as much of my Responce as possable i wish to make a Fully Divided one.
My problem is with there being three Exhaust Runners how do i make it Devided whilst still being ballanced?, is it as simple as running 2 together then keeping the dubble one and the single devided? But would'nt that be defeating the Object?
This is somthing that's been bugging me for a while, Any Idea's?
Thanks.

I don't think that will work. The whole purpose of the divided manifold and turbine housing is to separate the exhaust pulses.
I guess you could make a custom 3-way divided manifold and turbine housing. The main problem with this is that while nozzle #2 would hit the turbine at a nice 90deg angle, nozzles #1 and #3 would hit it at more acute angles, depending on your AR ratio. A radially divided setup would solve this issue, but then reversion would be a problem.
I think you are better off just using a nice low-inertia BB turbo, or going to a twin or triple turbo setup.
