Default stock ls1 airflow numbers

i currently have a porsche 944 turbo that i'm working on an ls1 swap. i have an idea for a 1 off turbo set up that i'm not willing to reveal yet, but would be more than happy to when its done. for now my question is on a stock ls1, what is the typical volume of air drawn through the motor at WOT if anyone knows that. i'm looking for an amount in cfm and its corresponding RPM but i can develop my own graph if i had a starting point. any information would be extremely helpful.
