Mike, realistically the gains are minimal, I'll give you my basic theory
about Ram Air...it is doubtful that any ram air system will create any
positive pressure within the combustion chamber, Ram Air is useful for
overcoming intake restrictions, however, and helps reduce "negative boost"
within the intake system, mainly in helping overcome the restriction of the
air filter.

In the case of my car running 034efi, my intake tract consists of an HKS foam
cone filter with a 3" opening, about 8 inches of 3" ID flexible hose going
directly into the 3" inlet of my T4 compressor see: <A HREF="http://80tq.com/images/turbo_intake.JPG">

The key is getting cool air and reducing intake restrictions, "ramair" can
help do both, but don't look for more than 1 or 2 hp or none at all due to
the effect of positive pressure.
