HX35 Max Boost?

Say MM NO go on the access to the thread. I guess that access is above my pay grade? I'd like to read all about the long hair.

The compressor MAP shows about a 4.2:1 pressure ratio, so at sea level it would be capable of 47 psi. The problem is that it's only a 52 lb/min turbo, and generally on our trucks when you get to 40 psi you are above 52 lb/min so you are over-speeding the turbo. Peak pressure ratio is only at 30 lb/min. Peak airflow on the HX35 is at approx 3.0:1 PR, or 29.4 psig at sea level. So if you lived at 2K rpms you could probably get away with 35-40 psi, but if your tuning your WG for the full rpm range I wouldn't set it much above 30. That's also the comp wheel, and doesn't take into account the flow of the turbine which may create excess backpressure and thus effect overall flow.
