HP gains in GT Speed over GT, explanation?
GT Speed will have 600 HP vs. stock 552. WHY?? Differences with ECU software? Engine size is same bore and stroke and compression. Differences with intake or exhaust side of engine or turbos more boost??
CONTINENTAL GT
DYNAMIC
From Evo car review: Bentley’s head of engineering, Ulrich Eichorn, is quick to kill the not entirely unreasonable layman’s notion that this performance boost was achieved simply by turning the wick up a little on the twin-turbocharged W12 motor. It’s hardly an over-stressed engine after all. But no, instead they took the ‘diligent, in-depth approach’, improving the cooling efficiency and gas flow through the engine, lightening key components such as the conrods, reducing exhaust back pressure with new catalysts, reducing weight with a single-chain camshaft drive and sharpening up the engine management system.
Any direct knowledge appreciated. Thanks mark mburnste@dmc.org

From what I've read, the GT Speed has a different ECU tune, slightly more aggressive cam, and a slightly altered intake. Might also have a freer flowing exhaust and more boost.
