Any idea what this Schwitzer flows?

[GNVenom]

Here's a challenge. I don't have any spec on this turbo, but I'm using two of them. They're small, and will probably spool like a banshee. I would like to find out how much airflow at what boost the turbo is best suited for, and whatever info anyone might have.

The turbo in question is a Schwitzer designed for John Deere applications:

Schwitzer Mod. S1B
John Deere P/N RE 71550
Schwitzer P/N 316101
Serial No. 03E01-0296

Any help very appreciated.
