compression and altitude.

[James Nazarian Jr <James.Nazarian@Colorado.EDU>]

Does anyone know how compression varries with altitude?  I should think
that a compression check will not yeild the same numbers at 6k feet as it
will at sealevel.  Also is there a relationship of compression to
horsepower?  For example if compression is increased 10% then hp will
increase by x%?
