Exhaust gas pressure with a turbo
This may look like just a DIY gas turbine engine, but what it really is (was) is a turbocharger test stand. It was used to test this turbocharger under simulated engine loadings: http://propulsiontech.com/turbo.html & http://ecomotors.com/electrically-controlled-turbocharger#
That is me starting the generic turbo with a leaf blower. Cylinder at the far end is a combustion chamber. Compressor discharge was fed into it. With a VFD on the injection pump motor we varied the diesel injection pressure between 50 and 500 psi. The resulting hot gasses drove the turbine wheel. Eventually we put a throttle on the combustion chamber inlet to better simulate different engine loadings. Without it we could only trace a curved line thru the map. With it we could explore the whole map. We also got to the point where we were blowing those silicone bulge hoses off no matter what we did. As you may expect that was right around 40 psi. I eventually replaced them with more Marmon V-band assemblies.
