CFM airflow in a 5.0 V8?

[Papa]

How many CFM of airflow does a 5.0 V8 suck in @ 2,000 to 2,500 RPM? Does anyone know how to figure it out or can you point me in the right direction?

220.7166404455298 CFM@2500rpm @WOT at 100% efficiency. Cam profile changes this.

5 liters, but it only intakes 1/2 of that per rotation- so divided by 2, multiply by 2500(rpm), then convert the liters to cubic feet

or

302 cubic inches, divided by 2, multiplied by RPM, convert answer from inches to feet

hahaha nice

I am not sure if this has been measured, why do you ask?

Sounds like he's trying to tune his maf for cruising speed MPG

I forgot to mention, most stock engines are around 80% efficient, so multiply my answer from above by .8 This is still assuming WOT.

Actually I was going for 65 to 70 MPH as I try to work some ideas out in my head. Yes turbo chargers work really well but way $$$. I have found the a certain amount of ram air can be developed if you block off the opening below the head light and the OEM air intake. Your information is most helpful.
