I've admired the Veyron since it rolled out. Had no idea it generated that much heat! It even has Titanium con rods and coated pistons. 10 radiators?
I agree, there should be some way to recover some of that energy. I recall in WWII the Wright Cyclone had power-recovery turbines, geared directly to the crankshaft. It gained 150hp per turbine, I think. Found it: 550hp-->
http://www.enginehistory.org/Wright/...ompounds.shtml Could be an idea...a working turbine extracts energy, which would cool the exhaust. The W16 is an 8L (487ci), so I don't think it'd get as much as the R3350, but should get something.
