Lancia Delta ECV

[jack_christie]

The successor to the Group B Lanica Delta S4, what would have been the Group S Lancia Delta ECV, finally made its competition debut in the hands of Miki Biasion and Giuseppe Volta at the recent San Marino Rally Legend 2010 event.

ECV1

If one car could truly sum up Lancia's DNA it would be the amazing ECV1 and, two and a half decades after its first public appearance at the Bologna Motor Show in late 1986, shocked the rally world this 600 bhp rally 'laboratory' prototype fitted with sequentially-operated dual turbochargers finally hit the special stages in anger over the weekend in San Marino during 8th Rally Legend 2010.

ECV2

A further development of the ECV would have been the ECV2.

The turbochargers aren't sequential on the Tri-Flux as can be easily seen in the below pictures. So unless they are using some completely different powerplant than was originally intended for the ECV (perhaps some modified S4 motor) someone has made a mistake.

That engine looks awfully similar in concept to the aborted Alfa Romeo 4-cyl turbo F1 engine of early 1987... 4 cylinders, 2 exhaust pipes per cylinder, twin-turbos.

huh... Were Lancia and Alfa under the umbrella of FIAT by then?

Yes they can !

The cyl-head had crossed exhaust and inlet valves, with an exhaust manifolds on each side of the cylinder-head, each feeding a single turbocharger. The use of two relatively smaller turbochargers reduced their inertia, hence spin-up and turbo-lag were reduced. The engine also had sequential activation of the turbos; at low engine speeds one turbocharger exhaust was shut-off, forcing all the exhaust gases through the other turbo and thus providing good low speed pick-up performance. As the engine speed rose, the second turbocharger was gradually introduced, until at high engine speeds both turbochargers ran in parallel offering the best top-end power. Pneumatic "throttle" valves were used to control these exhaust flows.
