[Diy_efi] "Wet" Manifold Questions

[Kenny W]

Quoting Jurgen Hartwig <jhartwig at midsouth.rr.com>:
"True, but one reason perhaps to bypass an intercooler 
is due to the internal
restriction.  If you are running 6-7 psi of boost and 
the intercooler robs
1-2psi, that would hurt, wouldn't it?"

I don't see why. That why there's a wastegate. If the 
compressor isn't sized to have enough headroom to 
compensate 1-2psi then I'd suggest the whole setup 
should be quickly garbaged. The extra heat generated by 
the compressor to overcome the pressure drop introduced 
by the intercooler is more than compensated for by the 
intercooler itself. So the turbo actually does 9psi of 
compression and the engine sees 7. As long as the 
engine still sees 7 then who cares? And that 7 will 
still be cooler than the nonintercooled 7.
