Hello Carman,
I have been fully occupied with development recently and a buit short of time visit the forum.
The RSR manifold is a nice looking one. My only concern is the material used, water and methanol is not good for alunimium. We made intercooler spraying rails in either stainless or brass. It is not as pretty but functional.
It may not be appropiate mechanically but may be modified to suit.
Here are some pictures of the rail:
