My thoughts exactly. I've not been in the rotary world for a while, but has there been overwhelming success with a setup that has the TB and runner perpendicular? IMO, Mazda designed the system that way for a reason and you'd be better off coming up with something along those lines (TB parallel with runners), but with more volume, longer runners, smoother transitions, etc.

I'm toying with the idea of making a custom manifold for my ITB project, but obviously I won't have a lot of these same problems...
