13:1 cylinder compression ratio, 10:1 "net" using delayed intake valve closing, when "OFF-BOOST". And then with climbing boost pressure the engine gradually transitions into lower "cylinder" compression ratio reaching the current 8:1 only at FULL Boost.
Absolutly STELLAR FE in cruise, off-boost, and POWER with widening, WIDER, throttle opening.
Much better than cruising along (95% of the time??) with a derated engine, POOR FE, using low 8:1 compression.
