Kickdown's Take

by Louis Kalendruschat

This 911 restomod is absolutely one-of-a-kind! The biturbo engine was built by tuning guru Reinhold Schmirler and delivers an insane 850 hp. It also features a 6-speed transmission. The look is equally impressive, with high-quality Speedline wheels and a striking rear wing. No expense or effort was spared in this conversion, resulting in a spectacular 911.

    Technik: Trotz der hohen Motorleistung, die der 911 Turbo 3.0 bot, wünschten sich viele Kunden einen noch leistungsstärkeren 911er-Sportwagen. Porsche reagierte und entwickelte 1977 auf Basis des ersten Turbos ein leistungsfähigeres Fahrzeug. Der neue 911 Turbo 3.3 genannte Wagen leistete 221 kW (300 PS) bei einer Drehzahl von 5500/min. Erreicht wurde dies durch die Vergrößerung des Hubraums von drei auf 3,3 Liter, eine Erhöhung der Verdichtung des Sechszylinderboxermotors auf 7 : 1 und den zusätzlichen Einsatz eines Ladeluftkühlers. Durch den erstmals bei einem Serienfahrzeug eingesetzten Ladeluftkühler wurde erreicht, dass bei gleicher Kompression durch den Turbolader mehr Luftmasse in die Zylinder gelangte, denn beim Abkühlen nimmt das spezifische Volumen ab („die Luft zieht sich zusammen“). Gleichzeitig kann wegen der geringeren Temperatur auch die Verdichtung höher sein, denn die Klopfneigung steigt mit der Temperatur des verdichteten Gases. Erst diese verbesserte Innenkühlung ließ eine Erhöhung der Verdichtung zu. Der neue 930 hatte weiterhin ein Viergangschaltgetriebe, mit dem eine Höchstgeschwindigkeit von 260 km/h und eine Beschleunigung von null auf 100 km/h in 5,3 s zu erreichen war. LG Tom
