live4speedNo it wouldn't be cooler, it'd be hotter your getting the same engery being created in a smaller engine, theres less there for the heat to disspate though, also the small ammount of weight saved in the engine would be easilly negated by larger or additional radiators, just what the Veyron doesn't need more of.

I would like to take this moment to point out that the veyron has more radiators than all the houses in my street
