Intake flow numbers For SBM

I wish you could sleep better...lol. I always question the validity of testing just an intake. Without the physics of a running engine taken into the result it's just not really telling you much. You flow test a port but that has one end, feeds one hole, and is not fed off a common plenum. A perfect example is the Stealth and the RPM. The RPM pulled 30cfm less, and yet it's always making more of the same type of power over the Stealth.
I think you spent a sleepless night working when you could have been enjoying yourself...lol.

Is there any kind of documentation that confirms the rpm realy being that much better than the stealth? or is it just that way to many people somehow got stuck in some kind of magazine hype?

I see people recomending the rpm and the rpm airgap all the time but i cant find someone that can verify if there is a real difference compared to the stealth or action plus. or even the M1 dualplane.
