Well, I have not been talking absolute power, I think that's been clear, my
point is that power output of a 10v vs 20v engine wrt turbo is relative, say
the 20v head flows about 25% more cfm than a 10v (in that ballpart IME), how
much harder will a K24 have to be pushed to create the same power output, its
relative, especially when you bring in factors such as turbo efficiency and
how they relate to IC size, and other flow related issues such as intake and
exh. manifold design - the 20v is in better shape wrt to all the above.

I'm talking practical application, even with EFI, a K24 will need to be
pushed very hard to produce the cfm needed to make 280hp, of course it only
gets better with head work, cam, etc.

I know first hand how much power a 10v can make, I spent about 2 years
tinkering with 2 TransAm cars, those motors were easily making 5-600hp, but
they were no were near the motors that we get, relatively speaking.

My advice to anyone looking for 280hp is a 10v, stay away from maxing out a
K24, and use a bigger turbo which will be much more efficent at those kind of
air flow levels.
