Dry Sump System
Unlike a wet sump system where oil is stored in the sump, a
dry sump oiling system stores oil in a separate tank, leaving
the sump essentially ‘dry’.
Two internally-mounted pumps, are used to ‘scavenge’ (1)
oil and deliver it to the storage tank, and then deliver (2) the
oil through the engine. The primary advantage of a dry sump system is its ability to
make more power. With very little oil in the sump, the
rotating assembly is not burdened with the weight of excess
oil (windage). The windage tray or screen which serves to
isolate sump oil from the rota
ting assembly, runs the full
length of the sump.This keeps the rotating assembly free of
windage and allows it to spin freely and make more power.
In addition, the extra crankcase vacuum created by the dry
sump pump helps to improve ring seal for additional power
gain.
Other advantages of a dry sump system include increased oil
capacity, more consistent oil pr essure, the ability to easily
add remote coolers, and adjustable oil pressure. And
because the sump does not stor e oil, it can be relatively
shallow in depth to allow lower engine placement for
improved weight distribution and handling.

Exhaust (09.00)
Silencer Assembly (09.01)
Variable Flow Silencer Assembly
The rear silencer assembly has a variable fl ow path controlled by two bypass valves.
The system is intended to enhance top end performance in mo tor sport applications and will not operate in most normal
driving conditions.
By directing exhaust gasses through a modified path at high vehicle speeds, exhaust back pressure is reduced and top end
performance is enhanced.
As engine speed increase from idle, the bypass valve is open until the engine speed is 1500 rpm.
From 1500 rpm to 3000 rpm, the valve is closed
Above 3000 rpm the bypass valves state is load dependent (fully open at higher loads).
