Also, you have to keep in mind. What is a company's idea of
almost, nearly, virtually, practically 0 pressure drop?
Is it 1psi? 3psi? They should be able to provide an exact # at a given cfm.
Example: A core that measures 6" header-to-header x 24" wide x 3" thick, flows 770cfm @ 10psi w/ 1psig drop out the back.
And that is with the fpi that we use. If we changed the fpi as much as 1, it would change the cooling efficiency.
Out the back= outlet side.
Moving on. The 24"h x 10.25 x 3.5" core, and this is being generous based on the fpi, would flow approx 371cfm @ 10psi w/ a 1psi drop.
The longer the tubes and the greater the fin count, the more resistance you will have.
I have been looking into using (2) 8"h x 12" x 3.5" vertical flow cores/ dual pass.

Get that car on the dyno and take an IR gun to the bottom and top sections of the intercooler. You will find that you are getting NO airflow to at least the upper 30% and probably the upper 60% of the core. If you can't understand something as basic as path of least resistance and laminar flow, I wouldn't let you pump my gas, much less come anywhere near my ECU.
Explain to an idiot like me how you're getting airflow evenly across that core. Until you can, keep standing by your vendors with inferior product. You CAN make that IC work and work well, but you would have to ditch those end tanks and cut the core down on the sides a few inches in order to weld a proper endtank on there. Too much work, IMO, when there are proven solutions out there that work, like the Buschur Racing intercooler with "backyard welds"
Definite bling factor on that IC, if that's what you're into. Might go well with that red IC piping you have that's got more curves than a Siamese hooker.

Hell, that's as basic as Maximum Boost.
"Backyard welds"?? What is that supposed to mean? A nice thick buttered weld is a thing of beauty. Maybe you've seen too many bolt-on parts that have been laser welded.

the end tank design got me thinking too... my buddy really like spearco and he told me that they had a reason to do that... they design the end tank really thin and only limited amount of air can go through the small tubes in the intercooler which forces rest of the air to get pushed up the end tank to get cooled..... i dont know much about intercooler design but that makes some sense to me..
