Not all intercoolers are created equal!! core comparison pics inside!!
We're a huge supporter of Precision products as well as their intercoolers. I had another intercooler come in so I had a chance to take a pic showing the fin density of each. I just wanted to show that not all bar and plate intercoolers are the same. Precision core have a higher fin density which does make a difference in cooling the intake charge.
This is a Precision 750hp AS1026 core looking in from the end tank
This is a competitor's core used by many shops around the country in multiple different markets. These cores are cheaper than precision or garret cores and while they still work well, they are not the same

Why don't you post some real data rather than conjecture. If fin density was the only parameter which made a heat exchanger perform better you might be onto something.
I think this test has been done by ETS and David Buschur already on a Dyno with IAT data. Look around.

All intercoolers are not equal 
You have a lot to take into consideration when purchasing a front mount.
The first thing you want to check out is the fin pack design. An offset and staggered fin design will be your best bet in dissipating heat. The straight through fin design will pass the air right through like a tunnel, the offset and staggered fin pack breaks up the air molecules and forces the air to come in contact with multiple fins creating a denser charge air.
** ETS Offset and Staggered Fin Pack
** ETS Core (Dense, Offset and Staggered)
** Ebay Core (Notice how the air flows directly through the intercooler and not off the fins)
The next would be the intercooler core design. We prefer a bar and plate core. This cores does an amazing job at being efficient.
** ETS Core VS Garrett (We do something a little different here by changing the size of the charge row to give us more heat transfer plates. If we have an extra 4 charge rows over the competitor core in the same area we get 8 extra heat transfer plates. This is the top and bottom plate of the charge row. By doing this we can loosen up the internal charge rows which gives us less pressure drop and more external heat transfer area.
Here is a picture of the Garrett core that we cut in half to make a smaller SRT-4 intercooler. The internal results of the Garrett core were a bit disturbing. The core doesn't look like it would flow too well.

Hope this helps you out.

There is such thing as too much fin density. Too much and you create a high deltaP. It's a balance.
When we were working with SRT rally, they wanted to increase the inlet/outlet size because they thought the cast endtank inlet dia. was the restriction. I recommended decreasing FPI because they were well within their inlet temp range. All we did was loosen the FPI on the charge air side and they found the power they wanted. Along with increased throttle response. It really is a science.

We have a bunch of R&D in our cores, but if we post all the info, we are going to help out a bunch of competitors which never works good in our favor. I like selling a product that performs on all our customer cars, not sure our shop cars.
We see a lot of big builds from other shops and they can make the power but if the customer can never make the same power, what's the point.

Here is the type of testing we do.
