What about that accordion? - ZR-1 Net Registry Forums

As part of a TB upgrade, I saw where the air horn had been thinned to increase efficiency. It occurred to me later that opening up the air horn could be mooted by the "accordion" tube leading into it.

It raises the question of what (if any) improvement could be had by having a smooth link as opposed to the stock accordion link? Would the accordion type tube negate some/much of the benefit one might be trying to gain by upgrading the TB? In other words, would it be advantageous to installing an aluminum sleeve inside the accordion hose for support (AND air flow) instead of wire support hoops (often used for support)? If so, how much? (I mean when you think about it, so much is done to smooth the air flow when P&P'ing the plenum/IHs, etc, why wouldn't it apply to that intake hose?
