[SOLVED] SuperH compressor map

Does anyone know where I can get (PDF file) the compressor map for a T04B turbo with the SuperH compressor wheel? Turbonetics mysteriously seems to not have any of the maps available.
Thanks, Andy

The Super H would just be a wider version of the existing H-3 compressor map due to the larger major diameter on the compressor wheel. H-3 Map:

Robert, thanks for the information. Can you make a quantitative guess on wider? I am targeting 55lbm/min max airflow. Based on the map of the H compressor wheel, max air flow is 50-52, just slightly less than I am targeting. Specifically what flow rates would you expect for the 120K RPM/60% efficiency and surge line for the SuperH?

Thanks for your time,
Andy

With the larger major I would expect the surge line of the compressor to move to the left at the low end of the pressure ratio axis. 55 lb/min might still be on the harry edge but should still work.

Robert,
I just did a freeway data log this morning with a couple of good pulls in 2nd/3rd gear. The pressure rises to waste gate setting pressure (1.8 atm absolute) at about 5500 RPM but then begins to drop and then oscillate about 6300 RPM. This is a 3.5L 911 motor. There may be other explanations of course but am considering moving up to the 60-1 compressor but would require replumbing the intake as it has a 4" inlet port diameter of the compressor vs the TO4B SH which has 2.75" . Other than the challenge of fitting the 4" plumping in a very tight space, can I easily change the compressor housing and wheel to the 60-1? There is also shown a 60-1 HiFi compressor which still uses the 2.75" inlet. Will this achieve the flow of the 60-1? if so how? it has an impeller input dia that is only .025" larger than the SuperH, the same compressor inlet size, and the same major diameter of the wheel?
Thanks,
Andy

The 60-1 HiFi is a full 60-1 compressor wheel in a machined T04B housing. It flows about 90% of the full size 60-1 unit so it should work well in your application.

Robert,
I am picking up this thread from over 6 months ago as all work on my car stops over the winter and spring months here in Chicago! You had recommended the 60-1 Hifi and I was wondering if I can convert my existing TO4B (with the H-3 compressor) changing out the impeller only, or do I need to also change out the compressor housing? Should I buy a complete new unit? What are my options?

The 60-1 compressor map does not have any efficiency numbers marked on it, do you know what they values are for the island on outwards?
Thanks,
Andy

You would need the 60-1 HiFi compressor housing as its machined out to fit the 60-1 compressor wheel. As for the compressor map the 62-1 map right below it uses the same efficiency rings as the 60-1 and you can use that for reference. Buying a new unit might be the best if you want the latest and greatest turbine wheel as well.
