Easy Run Engine Test Stand

Meh, it's nice, but not $2,500 nice. The steel around here would be less than $150, the wheels $65 from a local guy I know. Some cutting, welding, and some extra parts and you're in for far less than a grand. If you can't weld, a case of bear usually does the trick.
I think you may be skimming over some stuff
There is a radiator on there, I'm guessing it has fans mounted to it, a fuel tank, and a dash panel with some gauges

I have no doubt it can be build for less, but it does seem like a nice all inclusive package
