Good topic!
I love the idea of being able to run as little boost as possible but still achiving massive power - which the zetecs seem to do.
But I also love that kick of power that the CVH provides, even on a T34 it still gives you a shuve in the back.
For me 1905cc CVH gives me the best of both worlds. Able to run lower boost to achive the same power as a 1.6, low down torque like the zetec and still have the charactoristics of a cvh.
