Can't give you the torque without a full compressor map and some sort of idea of the intercooler size, sorry!
It's easy to do a rough guess of the maximum airflow (probably slightly generous on the power really but depends on the inlet temps) but flow and efficiency at a specific rpm is a bit more work!
