I know MAF flow numbers have been kicked around before, and I know Richard Clack had that get together in 2008 where he was checking the flow of a bunch of stuff through turbines (who took notes??). So what I'm looking for is a compilation of whatever data is available. Here is all I was able to find in my old files. It was a post by Mike Licht in 1998:

Stock MAF w/ 1 screen = 687 cfm
Stock MAF w/ no screen = 809 cfm
3" Impala SS MAF stock = 772 cfm
3" Impala SS MAF w/ no screen = 875 cfm
3.5" F-body MAFF stock = 940
3.5" F-body MAF w/ no screen = 1,040

I recall a guy in AZ flowing a bunch of stuff well over a decade ago as well. So, who has more information that can add to this?

I also have a couple things on throttle bodies from Jay Jackson and Accufab... maybe put everything I have here?
 
Amazing how much difference there is between the MAF with a screen vs. without. Wouldn't think the screen was that restrictive (100+ CFM!). How well do these cars run without the MAF screens in place? I was reading the TT web-site & it recommends at least one screen for their chip to operate correctly.

Thanks
