The Lancia ECV Engine
"The car originally produced over 600 horsepower (448 kW) from a 1759 cc twin-turbocharged engine. This engine, christened Triflux , was built in an unusual fashion; the valves where crossed (for each side of the cylinder there was an intake and an outtake), so that the two turbochargers could be fed with two separate manifolds. A single manifold carried the intake air (hence the name, from the three separate air ducts). However, Group S rules would have artificially limited the car's output to 300 hp (224 kW) to limit speeds."
