Since carbs measure in fuel flow based on VOLUME of air flow and are
grenerally calibrated based on atmospheric pressure air, you'll have to increase the
jet sizing to allow for increased MASS flow of the compressed air since more
lbs/hr of air require more lbs/hr of fuel. Also, the fuel pump ain't gonna
move any fuel when the boost pressure is 8 to 10 psig and the outlet of the
pump is only 5 psig. So you'll have to figure out how to boost the fuel
pressure to compensate.
Good luck!

Turbocharging and supercharging work the same way ... they are just driven
differently.
Ford and Kaiser supercharged their engines. I don't remember what Ford did
but Kaiser
built a cast iron box around the carb so the pressure would be on the fuel
bowl as well as through the venturi. There may be a need to adjust jetting.
---------------------------
You can turbo-charge an engine one of three basic ways, with fuel
injection,
or where you suck air through the carburetor, as a standard corvair turbo,
or where you blow air through the carburetor. Does any know if anyone
attempted to modify a corvair standard turbo engine by removing the
standard
carburetor, and just using an air cleaner, and then blowing the air through
2
standard 110 carburetors by modifying the tube running from the turbo to
the
intake. I am looking for anyone who has done it or may have some pictures
of it?
