I have seen ITBs on high end twin turbo conversions. There must be something to it. My thinking is that ANY reduction in the length from the throttle body to the intake valve is a good thing, even in a turbocharged application.
I would like to know if there are any negatives to using ITBs with a turbocharged system. I think Goran (BeepBeep) touched on the subject somewhere in his It'sFun2 thread, unfortunately I'd rather not read 1000 lines of posts again to find that sentence.
By negatives I am thinking about such things as "how do you bypass the throttles during closed-throttle events" and "is there a signifcant air flow interruption in the design needed to house these ITBs in a turbocharged application".

As far as having a continuous 1bar of boost available at all times - that would be a good job for a supercharger. I could see some REAL possibilities there.

EDIT - Looks like one of my questions was answered while I was typing. Throttle bypass would be a problem.
