Some intercoolers are good because they are big and some are good because they flow well. Does anyone which are the best in each department?

Depends on the application. There's no one perfect part for anything.

Which ever intercooler makes the best out of space that is given in the bumper for air to flow. It depends on which bumper you have, it depends on your boost setting, and it depends on where your putting it.

there is a balance you want to get for optimal performance, if you run stock seq twins and you have a Nissan GTR FMIC, you will find a lot of lag as the turbos struggle to push the air through such a large area, not to mention plumbing. If you upgrade to a huge single blower there isnt an issue.
I run stock turbos ( non seq at the moment) and I found a 400 x 300 x 100 FMIC to be optimal for my setup.
Like fastcarfreak said it depends on a lot of things.
My philosophy is Balance.

Actually the turbos don't struggle at all, they just take more time to fill the volume of the large ic. That's where the lag comes from.

which is why I prefer a stock mount intercooler

that and b/c I prefer not to obstruct the radiator so the car cools well.

So what kind of testing did you do? Core sizes, end tank designs, etc?

How did you test efficiency of the core?
