The TRX 2.5 Racing Engine
Introduction
There's nothing like the TRX 2.5 Racing Engine in your new
S-Maxx. The TRX 2.5 Racing Engine is vastly superior to typical
R/C engines and belongs in the category of specialty high-
performance racing engines. It's the result of years of focused
engineering development, and thousands of hours of
controlled testing and rigorous real-world running. It offers
unprecedented power and performance that turns ready-to-run
into Ready-To-Race
®
.
The TRX 2.5 Racing Engine takes a total-system approach. Each
part of the engine, from the air filter to the exhaust tip, is
carefully engineered to work in harmony with other engine
components. Each part complements the next, to extract
maximum power. The TRX 2.5 is designed to be tolerant of
variations in tuning, and to run successfully through a wide
range of variable atmospheric conditions, such as changes in
temperature, humidity, and altitude.
The TRX 2.5 is manufactured to exacting tolerances and requires
a specially-designed break-in procedure to accomplish the final
precision fitting of the internal engine components. It is very
important that you follow the new break-in procedure as closely
as possible to achieve the best performance and longest life
from your TRX 2.5 Racing Engine. Old style break-in procedures,
such as simply running the engine with a very rich fuel mixture
for the first 4 tanks of fuel, will not achieve the best results.
Follow the steps in this manual.
A routine maintenance schedule is also required to keep the
TRX 2.5 in top running condition. Cleaning the air filter after
each hour of running is particularly important. Also it is
extremely important to perform after-run maintenance on the
engine to prevent corrosion from building up on the internal
engine components (see page 45).
Traxxas strongly
discourages changing
or modifying any part
of the TRX 2.5 Racing
Engine. Old tech tips and
tricks that may have
boosted the power of other
engines could seriously
diminish the performance
of the TRX 2.5.
There's more advanced
thinking, development and
testing in the stock parts of
your TRX 2.5 than in many
aftermarket manufacturer's
so-called performance
parts. The TRX 2.5 is already
the most powerful engines
in its class and simply will
not benefit from average,
low-tech, aftermarket bolt
on performance items.
