Description
An
indispensable
part
of
any
high
powered,
high
speed
engine.
The
combination
of
high
lift
camshafts
and
these
oversized
valves
will
greatly
increase
the
flow
rate
for
fuel
mixture
to
enter
the
combustion
chamber.
When
upgrading
the
valves
to
cope
with
the
new
high
lift
camshafts
it
is
also
a
requirement
to
upgrade
the
valve
springs
to
suit
the
new
setup.
High
engine
speeds
and
the
dynamic
movement
of
the
valvetrains
mass
can
cause
unwanted
stress
loads.
This
can
cause
abnormal
movements
such
as
a
valve
jump
or
valve
bounce
which
can
cause
engine
failure.
The
Tomei
Retainers
are
made
from
titanium
alloy
for
added
weight
reduction
whilst
maintaining
the
high
strength
properties
and
precision
required
for
the
nature
of
its
use.
This
will
help
keeping
the
valves
under
control
and
secure
the
valve
in
place
during
extreme
race
conditions.
The
strength
and
weight
characteristics
of
titanium
showed
best
results
during
test
conditions
of
5,000
revolutions
per
minute
during
the
load
conditions
from
the
valve
spring
and
camshaft.
The
light
weight
design
aids
with
smoother
operations
and
provides
improved
dynamic
balancing
to
the
valvetrain.
The
valve
retainer's
precision
is
an
absolute
must
to
secure
the
valve
and
valve
spring
in
place.
The
Tomei
precision
design
guarantees
the
optimum
smooth
operation
process
of
opening
and
closing
of
the
valves.
