Charger 3.5V6 intake air flow rate and temperature data

Hi All,

I own 2008 Charger 3.5l V6. Nowadays, I plan to do project on installing Eaton M90 supercharger. This is more like an engineering project to practice skills both in designing and machining, so I am not concerned about the fact that I can get 2006-2010 HEMI by adding couple bucks to my existing car price. Before doing something on my car, I plan to do CAD designing and calculations to be safe, so I try to get as much info as possible. I am interested in the following numbers and data:
1. Air flow rate at intake during vehicle operation (e.g. m3/s)
2. Air temperature at intake

That would be great, if somebody has tables or figures that would help me to start calculations related to the air flow. I have tried to find any exact data both in Google and this forum, however no success yet. If this data does not exist as open-source, is it possible to obtain this information from MAF sensor using e.g. Diablosport or something else? Thank you in advance.

Additional comments:
- I do not plan getting HEMI before I finish university. I understand HEMI is a way better platform for tuning and projects.
- I know about Tidalwave supercharger kit and I base my setup on it excluding what's not needed while using roots supercharger.

The cars use a speed density system to calculate fuel and air on the 1st gen LXs. So that means it uses intake air temp, manifold pressure, as well as other sensors to make the engine run. Also note that the 3.5s have a sort of variable runner system dependent on load and RPM. You can obtain some of the data you're looking for from a tuner or standalone datalogger. As to the exact information regarding air flow rate of the engine it doesn't come to mind but someone may have that information.
