Going Stage 2+

You've got to read this post off FB :scared:
Yeah the primary job of the end tank is to distribute the air into the core rails evenly. Cooling is secondary. The tanks aren't even in the air flow. The S3 cooler is a massive improvement over the GTI one. People just don't think it is because it's not a lot bigger. There is such a thing as going over the top with IC sizing. And remember, dyno cells have don't have the same airflow compared to the open road, so of course any cooler will heatsoak after 10 runs back to back in a cell. VAG designed the S3 cooler to work in Dubai. Heatsoaking it on the road in the UK would take some doing!
Paradox1:
If your aiming for top figures with k04 or another bigger turbo, go hybrid. I did mine for less that 200quid

I think you are exaggerating. My 6R/S3 intercooler was absolutely fine this summer running 23psi, KO4. Temps were always under the 50 deg timing pull threshold, even on that 33 deg day we had.
I think if people are heatsoaking an S3 cooler on public roads with a K04, they're overspinning the turbo and it's time to fit a bigger one running slower but more cfm.

That too. There are always cool off periods in between full throttle blasts for the cooler to dissipate the heat. If the turbo was in full boost all the time, even a 5 foot wide intercooler would eventually heatsoak.
