I'm building a genset for my home power using an old modified 5hp briggs as an
air powered driver, my question is; how much volume & pressure will it take?
If i use a gast compressor must i store the risidual air? Can i produce enough
air with the gast to be viable for turning the rpm needed in long uninterupted
runs?

Multiposting annoys lots of people. Some will tell you about it; some
will keep silent but put you in their kill files, which means you lose
the benefit of their answers to your questions, forever.

You should look up the displacement, and use that. As to pressure, the engine proper will be good to 100 psi, but the components around it are rated for much less. You'd need to keep rpm up, since the engine and its lubrication systems depend on a known speed to keep up with lubrication requirements.

No idea what you are asking.

The gast depends on electrical power. If you have electrical power, there are much easier / cheaper / safer methods of getting variable shaft speed. Like a VFD.

It is not at all clear what you want to do from your
description. You need to include significant amount of detail
including what devices are doing what jobs and the details of
the devices and hookup. Gast, for example, makes many different
types of compressors and air motors.

To give you a general idea of how much volume and pressure there
is a formula and a calculator at:

http://www.engineeringtoolbox.com/horsepower-compressed-air-d_
1363.html

Note this is a calculator for the hp required to compress the
air adiabaticly, that is without the transmission of heat. This
is not trivial to do. In addition, every time you transform
energy from one state to another you loose energy. You can
never get back all the energy it took to store the energy.
