Additional
Information:
1)
The
VALC
profile
allows
the
valves
to
open
faster
and
for
longer.
This
translates
to
faster
lift
and
increased
area
under
the
'lift
curve'
which
in
turn
generates
more
power.
(Greater
area
under
the
'lift
curve'
=
greater
air
intake)
2)
Unlike
the
valve
opening,
the
VALC
profile
ensures
that
the
valves
close
at
a
slower
rate,
helping
to
prevent
common
valve
train
related
issues.
3)
With
a
conventional
direct-acting
valve
train,
the
maximum
lift
is
usually
determined
by
the
size/diameter
of
the
valve
lifter.
Selecting
a
high-lift
camshaft
without
taking
this
into
consideration
often
results
in
the
camshaft
lobes
travelling
beyond
the
surface
of
the
valve
lifter.
This
causes
the
lobe
to
make
contact
with
the
edge
of
the
lifter,
damaging
both
components
over
time.
Therefore,
the
ideal
performance
orientated
high-lift
camshaft
needs
to
have
a
profile
that
maximizes
lobe
travel
on
the
lifter
without
exceeding
the
outer
edge.
VALC
profile
camshafts
have
achieved
this
ideal
by
deliberately
reducing
the
maximum
cam
velocity
to
limit
lobe
travel
on
the
lifter
surface. （Maximum
cam
velocity
=
lobe
travel
distance
on
lifter) Compared
to
standard
profile
camshafts
of
the
same
lift,
VALC
profile
camshafts
are
able
to
then
then
off-set
the
difference
for
even
greater
lift/performance
gains.
