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.

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.
