I talked to JBrady few days ago when we were discussing the SSTT issue. He suggested Small turbine, small A/R & Large Compressor. The small turbine will spool up faster, however it will be restrictive and large compressor will provide mass air flow. How would this solve the restriction problem? Everyone want to have low end torque. JBrady suggest the restriction can be moderate by two or more wastegate. Basically, the WG will bypass the excessive exhaust flow to prevent over spin of the turbine and restriction.
Its an very interesting idea and looks bright in it cocepts. Here is a picture of this example:
The WG is the primary gate control to moderate the exhaust flow and turbine speed. Aside from the concept, which turbo (turbine/compressor) would fit into this application of our engines?
FYI: I did not come up with this concept, the credit goes to JBrady.
