I use Wagner Evo2 comp intercooler. It holds up pretty well at 17~18psi full range, either with stock or bigger turbo. A side note - bigger turbo runs cooler (cooler IAT and cooler turbo itself) because of less shaft speed and less backpressure. Turbo shares cooling oil with engine, so cooler turbo means cooler engine.

Last time of HPDE, 100+F ambient temp + 70+% humidity, IAT maxed at 125~128F, pretty stable, in every 20min section. TBH I didn't do longer than 30min as you did, so I don't know what could happen.

When you have enough cooling, you start to care about the rest - pressure loss, heat recovery and weight etc, then Wagner is the clear winner, at least for me.

Bigger auxiliary radiator will help for sure. CSF cooling pack is a nice upgrade, though you have to factor in the weight penalty on the front.
