IMO the only real way to test an intake is with pressure drop data AND dyno test data. I seriously doubt more than 1 or 2 companies even bother to test pressure drop (measure the difference between atmospheric pressure and pressure inside the intake) at various points along the intake path... without this data it is not possible to know what part o f the intake is a restriction and where to focus the efforts... if it is even needed in the first place.
In short if the pressure drop does not improve then the only gains are from messing with afr and or boost... not because the intake "flows" any better than stock.

Well, that just does not tell the whole story. Dyno gains with no tune only show gains not WHY gains were made. My point is that many intakes make power by "cheating" the maf sensor so it sees less air at any given rpm / load combination wich simply leans out the airflow and increases the boost a bit on an otherwise stock un-tuned car. Both of those things can be accomplished with a tune and since most of us will be tuned at some point.... that negates the reason for buying an intake.

Alright,
Here are the #'s!
Car was dynoed stock except for Ultimate Racing Axel Back, HKS BOV & HKS Drop In Filter.

Thats where the 50 shot of Nawwz comes in! lol
Im not sure what the dip is. Maybe the car is leaning out and pulling timing?
I think the dip is one of those things you get from installing an intake and not tuning it.
Im sure the dip will go away once I get a custom tune.
