Hi all, a proxy message from our Engine Head. Any advice most appreciated. Thanks,

To all in the loop
For my thesis this year I wish to determine how the restrictor is affecting the air flow in our engine. I have arranged to perform a test on our 450 cc engine which will produce a 0.38 Mach velocity in the restrictor which is only getting to the first part of compressable air flow. But I can determine the effect on our engine.
My problem is gaining access to a larger engine at higher RPM ( 600 cc 12500 RPM)which will push further into the compressable air flow regime and give a truer indication of the restrictors limitation. I have access to a dissasembled 600 cc engine which is not practicable to get running again and complete this final years academic studies. Or ask another uni to assist me in the test. One is willing to but later in the year, which makes it difficult to surmise a conclusion before I need to write a thesis.
The question is simply is there any one who has performed a test of air flow into their engine referance to engine RPM, with and without the restrictor to evaluate air flow through the restrictor into the engine??? If so are they willing to share this information???
Good luck to all in this years competition and I look forward to a response.
