I believe that it uses a Bell Core and fabricated at Speed Inc. I actually bought it use (new in box) from a guy from BMR so I don't have the original purchase receipt.
As for efficiency, as previously stated by the other poster, the pressure will find the path of least resistance. Remember that your backpressure (after the initial hit) goes all the way back to the compressor housing. That means that every passage is full in the IC and everywhere else in the system all the way to the top of the intake valve.

air doesn't "turn" until it hits a blockage (pressure) unless you are flowing close to the max amount of volume that the core can handle it would in fact go right down the middle because there is nothing in the end tanks to direct it otherwise. That's how I percieve what smokinhawk is putting it. I might be wrong on that but that's how I think the airflow in the core would behave. The 6 inch width can flow more than the typical 3 or 4" and there isn't any "channeling" going on in the end tank going from 2.5 or 3" inlet to 6" vs. the 2.5 or 3" inlet in a 3 or 4" core. Just my humble .02 cents. Correct me if I'm wrong.

The big picture here:
We are dealing with boosted applications. We tell the newbies, "Boost is a measure of Restriction", all the time.
The above is a true statement when blowing into the end of the said intercooler with an open end. When is a boosted application if the above qouted statement was true we would never see boost. Air in itself is its own restiction, causing the air behind it to follow the path of least restriction.
We need to be looking at this as a pressurized system, "Under Pressure" being the big picture. Air flow under pressure will follow the path of least restriction. Center IN/OUT intercoolers make better use of the core space. With that being said, in a pressurized system the core space is gonna be used period. Its all about core effectivness.
Sorry Guys. I had one of those Geek It Up moments

In a fluid dynamic sense the above cooler is not using the top and bottom rows to it's fullist cooling capacity, as dynamically the majority of the air will flow down the middle

ugg its hard to explain fluid dynamics to the untrained or non engineer..
but its not to hard of a concept to grasp, try to imagine the air is now water traveling down a river that widens. The speed of the water is highest toward the center of the river, indicating that most of the air volume is going down the center. If you have a top inlet and top outlet you keep the speed of the air the same, or utilize more of the core.
you will have a slightly more restrictive cooler but since your using more of the core you get a slightly cooler charge, its a bit of a trade off if you would rather have a cooler charge or less pressure drop.

I did a little research today. Here's the most technical write up that I was able to locate that even mentions the subject and is backed by some amount of ALMOST relevant data. LOL

It is also good practice, when you are unable to optimize end tank design, to have the inlet and outlet at different levels on the intercooler, so as to evenly distribute the pressure differences. Otherwise with an inlet and outlet at the same “height” most of the flow will only utilize the rows of the intercooler directly in front of the inlet/outlet.

i dont see the part about full boost thing not being an issue. you still have flow
basically that doc says partly on what i was trying to get across, now your bringing up turbulence issue, which i dont think that cooler will have an issue with.
ever see intercoolers with diffusers in them, they also help with bringing the air equally across the whole of the core.
