But I do think Chuck was asking for the ability to go faster , not over heat .

Lots of little items to find/fix as well as some higher dollar items. Just bought six coach batteries, should replace the tires. Wasn't thinking too clearly when I looked at it and almost no tire wear. Problem is date code 0706.

I've always worked with Multi-Wing on fans. They make a lot of different styles and shapes in both metal and polymers and have some very sharp engineers on board. As far as the shroud, I just find a good sheet metal house that can roll the orifice needed and weld it in. Most of the fan efficiency involves the fan blade style, inlet geometry, tip clearance to the shroud and axial placement in the shroud. I have an older article from Industrial Vehicle Technology that touches on some of these and will attempt to attach it.
