So why even bother with running a carrera, 964 or whatever single plenum intake on these motors? Do most of us use them simply due to $$ when it's ultimately just a 'rate limiting step' or compromise when trying to build the best turbo motor possible?

Or, to put it another way Kenik, when u are looking to optimize all of the above factors, is the cost and complexity of setting up ITB's and individual manifolds so much greater that it warrants going with a single plenum intake which is ultimately a compromise?

Just trying to learn some more stuff here.
