Hi Rusty,

    Been thinking about your question of  throttle body position and the
EDDIE.  I've come to the conclusion that with at Throttle body inserted in
the pulse path that at WOT there would be mimimal effect, however, if you
planned to cruise (part throttle) and expect any improved milage from the
increase volumetric effiiciency of the DIE then I think that might not pan
out.  The partially closed butterfly plates would probably have an adverse
impact on the pulse (would reflect a lot of energy back).

However, since most of us would probably want the extra HP from EDDIE when
we really need it such as WOT for take off or WOT speed runs, this probably
would not be much of a consideration.  But, thought I would mention it.  In
fact, I have an 4 injector TWM webber throttle body that I might consider
doing that with.  Depends on whether having a throttle cable running to the
throttle body on the plenum adversly affects the ability of my adjustable
manifold to move up and down.
