<< As I understand it, flow would have to be proportional to pressure -- it is
 the same size pipe.  I would even take the stand that it is a linear
 relationship at the pressures we are using.>>

Right, but its not the pipes that are making the pressure, you are completely 
discounting the compressor turbine size, housing volume, and housing AR, 
which all affect the amount of flow through the compressor into those pipes.
 
 <<However, I can see where there might not be a difference in charge mass,
 attributable to the difference in temperature.  A maxed out K26 at 18 psi
 would also be making a lot of high pressure hot air.>>

Well, yes, that is the major consideration, turbo efficiency, which none of 
the older KKK turbos are good for.
 
<< I would sure be interested in what the charge temperature is at the IC exit
 at 18 and 15 psi using a K26, and also using a RS2, all other things being
 equal.  >>

RS2 ain't much better, nothing fancy these days, I have discounted it 
completely as a turbo performace option, especially considering the $1500+ 
price tag, ya right!
