The
oil
pressure
when
the
engine
is
started
from
cold
should
run
at
90psi
at
4,000rpm.
When
up
to
temperature
the
oil
pressure
should
read
60psi
at
4,000rpm.
Maximum
engine
revs:
‐
8,600
rpm
The
rev
limiter
is
set
to
8,600
rpm.
Persistent
use
of
the
rev
limiter
will
damage
the
engine.
The
engine
oil
and
filter
should
be
changed
every
six
(6)
hours
of
running.
Do
not
attempt
to
adjust
slow
running
speed,
or
any
other
engine
parameter
without
a
laptop
connected
to
the
ECU
running
the
customer
version
of
LIFE
Systems
software
(available
from
Powertec).
It
is
important
to
log
the
number
of
hours
the
engine
is
run.
The
engine
should
run
for
no
more
than
30
racing
hours
before
being
returned
to
the
factory
for
a
rebuild.
If
the
engine
is
stressed
less
(i.e.
trackday
or
road
use)
the
car
should
be
returned
to
the
factory
every
30
hours
for
a
rolling
road
dynamometer
test.
Engines
which
are
not
raced,
regularly
cover
90
hours
without
requiring
attention
(providing
they
are
not
over
‐
revved.
Particular
care
and
attention
should
be
paid
to
the
down
‐
shifts).
Note:
In
the
event
that
the
engine
stalls,
the
ignition
master
switch
must
be
turned
off
and
then
on
again
(after
a
two
second
delay)
to
reset
the
ECU.
