The radical angle entering the head is what's killing performance with his throttles. You want bends as far away from the throttles/head as possible.

Take a look at kinslers K series throttle setup.

Damn. All it takes is a spark and you start a wildfire.

On the notion of the ITB's, Carrying over from a thread in the DE section here is my opinion of the mess:

It seems the problem is having the base of the manifold that will work properly with the correct angle etc etc. From my understanding on the subject not all engines will need the same sized throttle body, therefore those should honestly be left out of the equation in regards to realistically making a ITB manifold kit that can be used as a base. Fuel rails injectors etc can be outsourced, or engineered to be compatible with this "Base" setup that it sounds like we really need. There are plenty of companies out there that could make such a thing, but just like the subject of this thread it requires a certain amount of interest and sacrificial parts.

Keep the fire going.

Figuring throttle sizes for a given motor is quite easy.

Tuning length and distance from head is the tricky part.
