Controlling Underhood Heat on Turbocharged Cars

[derekf]

Ok, from this thread in the archives (it's the New, Improved, Twin Turbo Mule thread from the old site), I gather that twin turbo cars have an.. issue with underhood heat, and to deal with it things like:



stainless heat shields
Header coatings/wraps
heat shielded plug wires
some sort of shield to protect power steering hoses
additional oil capacity and oil cooling
and the obvious upgrades to the cooling system..

.. but what am I missing? Is there more that should really be done under the hood? Air ducts aimed at the turbos themselves (or is that a bad idea)? Anything else?
