The 911 GT2 |Drive
Lightweight design.
The six-cylinder twin-turbo boxer
engine is a compact unit offering
excellent cylinder charging and
torque-curve characteristics
as well as first-rate balance with
minimal vibration. The flat-six
design allows a low centre of
gravity with resulting advantages
for traction and driving dynamics.
The alloy crankcase consists of
two main sections, each contain-
ing one bank of cylinders. Thecrankshaft runs in eight main
bearings and is driven by forged
connecting rods. For optimum
strength and durability, we’ve used
forged aluminium pistons running
in Nikasil-coated aluminium liners
and cooled via individual oil-spray
jets. The results: lower frictional
resistance and a lengthy service
life – even when subjected to
heavy use.
The cylinder heads are made
from an extremely heat-resistantlightweight alloy. Each cylinder
bank has two overhead camshafts
driving a set of four valves (two
inlet and two exhaust) on each
individual cylinder. The valves are
arranged in a ‘V’ formation and
have a highly efficient dual-spring
closing action enabling higher
engine speeds. Performance is
enhanced with the aid of both
Variable Turbine Geometry (VTG,
see page 28) and VarioCam Plus
(variable valve timing and lift on
the inlet side). The benefits are
not only greater power and
torque, but also better fuel
econ-
omy and lower emissions.
Dry-sump lubrication.
This racing technology uses a
separate oil reservoir to ensure
consistent oil pressures through-
out the engine, even during pro-
longed periods of lateral and longi-
tudinal loads. After passing
through the engine, every drop of oil is returned directly to the
external reservoir. The flow is dri-
ven by two scavenge pumps in
each cylinder head and a further
two pumps in the crankcase. Gas
is removed from the returning
oil via a defoaming device in the
reservoir. The oil is returned
to the lubrication points in the
engine by means of a dedicated
oil-feed pump. With a further
scavenge pump in each of the
twin turbocharger units, the
911 GT2 has a total of nineseparate pumps driving the lubri-
cation system. The oil level can be
checked from inside the car via
the standard on-board computer.
The 911 GT2 is factory-filled with
Mobil 1 high-performance fully
synthetic oil. The exceptional
properties of this premium-quality
lubricant ensure reliable starting
even in the coldest conditions. It
also reduces wear and contributes
to the long-term durability of the
engine.
