you think of high performance trucks, a full-size Ford dually
powered by a diesel engine even one that's turbo charged-probably
does not leap to mind. But TTS Power Systems of Compton, California,
is out to change your mind. With their new module and exhaust
pipe, TTS can not only turn your big Ford into a tow vehicle
extraordinaire, but they can actually make your dually really
fly on the top end. And the best part is that the Ford will
still be smog legal because the upgrades are CARE certified.
to Jim Cole, owner of The Turbo Shop, there are two things
wrong with the Ford turbo diesel in its stock configuration:
the computer program, and the restrictive shape of the exhaust
pipe as it exits the turbo. In the old days, when you wanted
to make your truck stronger, you "hopped up" the
engine; you know, carbs, intake, exhaust and such. Now, thanks
to the miracle of electronics, what used to take hours of
machine work and hundreds if not thousands of dollars to accomplish,
you can now do in minutes with the installation of a high
performance module or "chip." The module is the
brain of the computer, where all the programming is stored.
Without a program to instruct it how and when to handle the
thousands of functions needed to make a modern truck run properly,
a computer is just a collection of electronic parts. And with
the ever-changing government guidelines, it is becoming more
and more difficult to make modern trucks run well at all,
let alone properly.
are different schools of thought about the best way to improve
the programs found inside today's truck computers. Some chip
manufacturers feel that the best way to improve on the original
is to change just a few sites or "addresses" in
the program, and leave the rest of the stock settings intact.
However, TTS feels that it is better to take total control
of the program, arguing that by making only a few modifications
to certain parts of the program, the truck could actually
end up running worse. When making their modifications, TTS
takes into consideration all the variables that the trucks
will actually be working under. They also take into consideration
how the factory designed the engine to run.
modifications to the exhaust system, TTS examines the operation
of the turbo in relation to the exhaust pipe. Instead of a
typical round exhaust tube, the one found in stock Fords is
almost flat in places. In a turbo system, the exhaust gases
coming out of the engine are routed through the turbo unit,
and it is the force of this exhaust that spins or "spools
up" the turbo. It only makes sense that with a round,
less restrictive tube the exhaust would travel more quickly
and spin the blades of the turbo faster. So TTS developed
a new three-inch tube that is not only round but is also mandrel
bent so it does not have the sharp bends that the stock unit
has. Sharp bends create turbulence and slow the exhaust flow,
which adversely affects the speed of the turbo.
TTS pipe has a drastic affect on the performance of the Ford.
Simply adding the pipe increases boost pressure by one psi,
reduces the operating exhaust temperature by 50 to 100 degrees,
and increases fuel efficiency by up to a mile per gallon.
The TTS module simply plugs in. With that the unit is reinstalled
and ready to go.
the new pipe is a little more involved. The easiest way
to remove the stock unit is to cut it out with a sawzall.
Make two cuts: one on the top side about four inches back
from the turbo, and one below at the bend. as always,
be careful not the cut the wrong thing.
hole is drilled for the pyrometer at the junction to the
little trimming is necessary to ge the new pipe in place.
Take the top half of the pipe and install it loosely in
the turbo, using a pen to mark the spot where it hits
the body seam. This seam will have to be shaped to fit.
Ise the saw again to make relife cuts and then bend the
seam against the body.
last step is to install the pyrometer.
recommends cutting a section out of the rubber in front
of the air intake to increase air flow to the engine.
also produces a very nice looking console for mounting
additional gauges. Here, exhaust temperature, tranny temperature,
and boost gauge have been installed. The unit is made
of material that matches the stock colors and has cutouts
The new TTS turbo exhaust pipe. You can clearly see how
restrictive the stock unit is compared to the new TTS unit.
Installing the module in the computer is extremely simple.
Just remove the cover plate and plug the module. The most
difficult part is removing the computer from the truck because
Ford has it wedged tightly in the corner of the engine compartment.
First, remove the mounting plate that holds the computer
in place. Then the bolts holding the inner fender need to
be loosened so that a prybar or screwdriver can be inserted
to spread the fender away from the outer fender. This will
leave enough room for the computer to be removed.
With the computer exposed, use a small blade to pry off
the cover plate. Use a cloth to wipe the area clean. Ford
uses a type of grease to protect the contacts, so this will
need to be wiped off.
