throttle body theory??

[Touring23]

Does anyone here have specific dyno numbers they can post? N/A car, different throttle bodies being the only variable?

Richard Holdener, Chapter Three:

The magazine MM&FF did a comparison, too; I don't have the issue handy at the moment. I'll try to remember to post the issue number when I have it.

I ask this question not knowing the answer either: How can a larger diameter circular piece of steel (i.e. the mass air meter) flow less air than a smaller diameter circular piece of steel with a butterfly in the middle of it (i.e. the throttle body). It just doesn't make sense.

Don't some MAFs have a bar running down the center of the bore, like the stock piece for example? The area calculations then would need an adjustment.

Neat discussion. Glad I checked in. :beer:

Yep, I have that book and the MMFF issues, but I'm in the middle of moving and have everything packed away in a basement.
