HEAT
BARRIER for KAWASAKI STX
12F, STX 15F, ULTRA 250X
(this is a re-post)
Sense the
posting, I have talked with
Scott and this next year,
this item may be legal for
every class of racing. CHECK
the '08 Rule Book.
This barrier will help keep
the heat of the engine from
transferring to the intake
plenum.
This will effectively help
keep the air cooler, (keep
it from heating up as much)
while passing through the
plenum before entering the
combustion chambers.
Cooler intake air will
always make a four stroke
engine run better.
Touch the engine and it's
HOT as can be...
Touch the intake and it's
HOT as can be...
Install the Rogue Racing
Heat Barrier...
... and the intake plenum in
now just warm to the touch.
The difference is around
20deg. from the engine and
the intake.
We have tested for the temp.
difference and we've tested
for the HP difference on the
dyno and found two horse
power gained from this
barrier.

I was talking with some of
the 'OL timers at the local
speed shop a while back.
They are in to the land toys
but in the end, HorsePower
is HorsePower when it comes
right down to it.
I explained a few of the
parts that I had made for
our type of watercraft
engines and they said it is
all a good thing.
The heat barrier gasket has
been around for many of
years. I installed them on
84, 85, 86 Mustangs back in
the day. With a space of 1.5
to 2 inches thick material.
It worked. If I didn't have
the experience of it working
on the Stangs I would have
never come up with it for
the engines we have now.
The way the guys at the
speed shop put it to me was
like Henry "Smokey" Yunick's
(famous engine builder)
figured out, " every 10deg.
increase in air temp = 1
horse power loss "
The more you can maintain
cooler air while it's on the
way through the engine the
better the engine will
perform.
Heat on the intake side of
the engine hampers
performance.
INTAKE:
The Rogue Racing intake set
up will provide a quicker
response to the pull of the
throttle.
Better reaction times. More
snap in the take off and
better response in turns
where the throttle is
constantly adjusted to
maintain momentum around the
turn.
This set up will help gain
on quicker throttle
response.
INTAKE SPACER:
The Rogue Racing intake
Heat-Barrier will help keep
the air intake plenum from
rising up with the engine
temperature. By installing
this spacer and keeping the
plenum temp down that gives
the engine a better chance
at getting cooler air to the
cylinders.
Hot air is expanded and has
less oxygen in it.
Cold air is condensed and
has more oxygen in it.
This intake spacer will help
reduce the heat transfer
from the engine to the
intake manifold therefore
not heating up,
(pre-heating) the air that
is going into the combustion
chamber of the cylinder
head.
This product has been tested
and proven to drop the
intake temp by 20deg.
adding 2 Horse Power Cool
air makes more power.
Will benefit stock or
modified engines.
NOTE: For those of you out
there with ported intake
runners, you may need to
match-port the barrier to
your custom porting.
I'm sure some will have
questions so please call and
ask away.
Heat Barrier ships with
install hardware.
