Hi have just bought a used grace as a backup but am thinking of having a toy around with it. Has anyone added a larger adjustable  pump to one of these or any other machine as i wouldn't of thought that difficult once you have built an extra section to house it. Also is it possible to add extra vacs to machines? will save me time playing if someone already tried.

A mytee air hog might be what you require.
