air flow #s ?

[Adger Smith]

And don't forget there are other things at play where the laws of physiscs don't apply. Kevin, On the Speed Talk Forum We did a pass around of a calibrated flow plate. Some of the guys were at The Engine Masters Challenge and spawned the idea. It is interesting the different #'s that were obtained all across the country. Most of the guys know a lot about what is going on & why.
I can tell you that a guy wanting to "sell" is more apt to use the 25 number than the 28. There are many reasons for that besides a big #. It is a shame that this industry has the "big is better mentality".
I've had ports that are very bad have better numbers at 25 than 36 or 28. Simply because of twist and turns that cause separation and swirl. You can't even tell the ports are bad until you step up the depression. (also steps up the FPM of the air flow) I don't think there is any number that can be considered the "Best" flow depression.
Hey, What is the best wine? Depends on the meal, doesn't it??
BTW: Just look at all the different numbers these carb salesmen use to sell their work. In the real world they mean nothing with the high FPM flow through a carb.
Yep, It's My .02 :~)
