You don't understand... how is the turbo ever going to suck air if the engine doesn't produce exhaust? You see, before the turbo can suck and push air into the engine, the throttleplate has to be opened first so the turbo can spool.

The air resonance rule always apply to boosted motors... But the discussion was about whether it applies to boost AND ITB's. By looking at the above concept, the rule does indeed apply to boost and ITB's.

It was Fullrace Geoff who mentioned that this rule does not apply to ITB's and boost... But I am not convinced though.

 

I'm not an engineer, nor would I ever suggest otherwise. This question is about curiosity and not my attempt at problem solving, i.e. I just want an answer from anyone who might have a clue.

Could you potentially solve the plenum problem (with ITB forced induction) by running basically the opposite of a merge collector into the individual throttle bodies? I mean, maybe run the charge air through a water-to-air cooler and then into a "medusa" style manifold that would pipe charge air to each ITB rather than to a dedicated plenum where the air charge would be scavanged as needed.

Just curious. You'd get a **** ton of top end this way, although I'm willing to bet you'd be lacking a lil torque in the bottom.
