The intake is plastic, pretty good insulator, but if you're going to gold the manifold, why not.

The stock intake already pulls air from the coldest area possible if the rad ducting is intact.
I dont see a reason to ditch the stock intake, it seems to work efficiently, and even more efficiently by doing the "snorkel mod".

I noticed a world of difference in IAT at the supercharger afterward. As far as the rotors go, you won't see any problems running 12.5psi on a 90F day even without a charge cooler doing spirited runs and street racing(with a conservative tune [although I wouldn't suggest tracking with this setup at these temps]).

There is always the option to go with alcohol injection just to be safe though. It cools the rotors and airflow down substantially, adds around another 1-1.5lb boost, and ups the octane level in combustion. I use it on ambient temps above 85F.
It's worth noting that you'll probably start to feel less performance at around 80F+.

Another thing you'll feel is humidity. A dry 70 degree day will give you a much nicer run than a humid one.
For safekeeping (this hasn't been proven by any means), I vent my charger crankcase pressure through the dipstick when it is at temp about once a year. The oil seal has been known to weep, so my best practice has been to run it at about ambient pressure when hot, and vacuum when cold. Haven't had any weeping since. This is all personal speculation, of course. You can do whatever the $*(& you want to do.
I've thought about doing a meth injection set up but it doesn't really seem all the common. Youre happy with it?

This is proven on NA cars and the theory doesn't change on this setup. It's not an open filter and the actual intake is in the bumper. Air in the filter housing will not really increase in temperature unless it's not being used. Once you get any form of velocity into the system then ambient (bay) conditions really become largely irrelevant.

I do understand that you're in a hot part of the world, I really should try rigging up the MAF IAT sensor into my rear O2 input so that I can compare ambient/pre/post charge.

Think about ideas like:
Better IC radiator
More water in the system
Better coolant:water mix
Larger water pump
Water/meth spray

None of these have been proven, except the last. But it may be what I'd try. However the issue may be the laminova core, which we can do nothing about.
By more water in the system, you essentially mean extend the lines/bigger reservoir so the is more surface area (? fluid dynamics idk.) to transfer the heat to?
