I have been told by an OEM-adjacent engineer that is absolutely a thing with big intercoolers. He also said that many of them were poorly designed as well (though I don't recall the details).
Volume/lag was my first thought. That's more space the turbo has to pressurize before you get the goods.
The 13T flows 390CFM at 14.7psi, which is 184 liters per second. How much intake volume is an 'oversized' intercooler actually adding?...
This is a great video that yall should watch.
Basically, at 184l/s, it would take like .05 seconds to fill a fairly large volume.
Or in other words, "lag" will not change even going to a YUGE intercooler.
