I wonder what counter-measures have been applied to the hood and bulkhead areas to handle the thermal loading from the "hot V" configuration.

On paper it sounds impressive but I cant help but wonder what it will be like long term.
 Putting the turbos between cylinder banks doesnt inspire a lot of confidence with me.

Turbos AND catalysts in the "hot V" - with the right sort of hood vent, it wouldn't need a windshield defroster.  Smiley
