Hi everyone,

I'm currently a member of the Ferris state formula sae team and we are in the process of designing a single cylinder turbo engine
for the 2019 season. I understand the basics of plotting points on a compressor map using predicted MFR and desired boost pressure.
However, i'm getting hung up with what happens when I reach choked flow within the restrictor. I calculated the choked flow from a 19mm
to be roughly 8.8lb/min so should I use a turbo that has the majority of its map under that such as GT06 or go with something larger like a GT12 and
choke the restrictor down soon while maintaining higher efficiencies.

Thank you in advance
