Ernest,

I apologize in advance if you have taken the following into
consideration already:

The units of manifold pressure that are usually used are inches of
mercury.  To convert inches of water to inches of mercury, divide by
13.6.  That means that the highest pressure that was generated was less
than 2 inches of mercury over atmospheric pressure of about 30 inches.
I'm not sure this is the amount of boost you were hoping for.

Steve Boese

I take away from this that:
- I will be able to make significant manifold pressure, even with a sub-optimal solution.
- that the shroud will be the most important factor.  A secondary effort

may be to get some of Ed's magical polyurethane casting goo to build an optimal shroud.
