We plan to do 2 types of test:
1) Measuring velocity at the vanes
For this we have to remove the turbine wheel itself and use a pitot tube to measure the velocity at the tip of the vanes in order to draw theoretical velocity triangles to determine turbine performance.
2) Full turbocharger test
For this testing mode we will connect up a custom made oil system for lubrication, along with a calibrated air system for setting the rack position in the VGT. We designed each of these systems ourselves for ease of use when testing. Once setup we plan to measure mass flow, pressure, temperature and turbine shaft rotational speed so that we can determine performance parameters for the compressor side of the turbocharger.
Below is a video of the first time we got the full turbocharger running:
