output is 118 hp per litre. This
increase is due to the two new
double-flow air filter housings and
the new variable intake manifold
with larger intake tubes than those
used on the 911 GT3. The greater
throughput of air increases engine
power. In terms of performance
data, the maximum torque of
430 Nm is reached at 6,750 rpm.

A consistent supply of oil to the
engines even at times of high
lateral acceleration, is ensured by
a dry sump lubrication system
(page 36) with an external engine
oil reservoir. The oil is cooled by
an oil-water heat exchanger. Both
of these systems have proven
themselves on the racetrack.
