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.
Thanks, I’ll look into the Wagner.

I haven’t found anyone that makes a larger Auxiliary radiator, yet....
