I am suggesting a core without the red area and better designed end tanks,inlet-outlet(diffuser,Nozzle)will work better than the whole thing as it is now with equally if not lower AIT's and less pressure drop.
Keep in mind, that the merit of a core is its efficiency versus its internal drag...
It will conduct heat from the top but no where near as fast as the turbo is putting it in,so will still be hot.
Why would you want to deflect hot air to the top of this core if it is relying on conduction/convection to cool?
If you do fit yours with the 60mm alloy pipes imo the AH one will be better than the Forge.I still think it would be even better if it was a little shorter as there isnt alot of airflow if any going through the top part of your core.
You really havent got a clue why the pipework goes larger in diameter from the turbo to the throttle have you?
The cooler does lower temps but at what cost to the poor little turbo?
The cooler will never flow enough air through a 51mm od inlet/outlet to get anywhere near the claimed...
And you dont think Audi went upto 60mm for a reason,i dont think they just guessed at that size,reducing to 51mm either outside or inside diameter is not good and will cause more of a pressure drop than 60mm,fact.
Its not just AIT's, good heat transfer in an intercooler that has a small pressure drop is what i would want.
You could butcher in an ebay special and get as low AIT's,doesnt mean it is an efficent intercooler.Its easy to have high heat transfer when there is a larger pressure drop because the...
