Has anyone built a 90mm Turbinator from Laser Design? I am working on one but am undecided on what size turbine to use. I have a Wren 44 and a Jetat P-20. The web site suggest a P-20. I have a P-20 on the E-Turbinator which is a smaller version of the 90mm and it is perfect. I just wonder if a Wren 44 would be too large?

Thanks in advance.
