See the key features that make the TRX 3.3 Racing Engine the pinnacle of power and reliability.
Piston and Sleeve
The lightweight reciprocating assembly allows higher revving performance and reduces parts stress. The piston is composed of proprietary material resulting in less wear and extended engine life. The material for both the piston and sleeve (true ABC construction) was selected for its consistent fit throughout the engine's operating temperature range. The sleeve ports are larger offering more efficiency and better scavenging for increased power.
IPS Crankshaft
The innovative crankshaft design has dyno-proven timing and port flow to optimize fuel delivery into the engine. The crank is surface hardened, precision ground and micro-polished for superior life and durability.
Connecting Rod
Knife-edged connecting rod reduces internal drag and turbulence designed to handle the power of the TRX 3.3. The channeled design directs oil flow down to the crankshaft.
Composite Slide Carburetor
The slide carburetor provides less restrictive, straight through airflow for more power and improved throttle response. Traxxas engineers incorporated superior internal design enhancements and precision not possible with traditional machined carburetor. The composite material also does not transfer heat like aluminum for more consistent tuning.
Crankcase
The TRX 3.3 uses a sophisticated crankcase engineered with high-tech porting, and cooling refinements to boost power output. Precision casting provides the strength needed for the TRX 3.3's high power output.
Ball Bearings
The quality and smoothness of an engine's ball bearings contribute to the life and performance of the engine. The TRX 3.3 uses only top-grade, ultra-high performance, large diameter ball bearings. Top quality bearings improve power by reducing parasitic friction. The rear engine bearing uses a high-tech composite cage for reliable operation at engine speeds that approach 50,000rpm!
Straight-through Exhaust Flow
The rear facing round exhaust port provides unrestricted "straight-through" exhaust flow. The innovative shape of the TRX 3.3's exhaust port was carefully engineered to provide unrestricted exhaust flow while at the same time, maintaining a low exhaust port height. The low exhaust port height provides a longer duration power stroke for increased efficiency and total power output.
O-Ring Exhaust Gasket
The exhaust header features an extra-tough, finned mounting base that dissipates heat and is sealed with a reliable O-ring gasket. This virtually eliminates troublesome, messy exhaust leaks that steal engine power and efficiency.
PowerTune Head
The giant Powertune machined-aluminum cooling head promotes even heat distribution for stable engine temps and rock-solid tuning consistency. The uniquely designed molded head protector is securely fastened to the top of the head with precision hex screws. The impact resistant head protector is secured to cylinder head with screws so it won't fall off. It's designed to absorb harsh impacts and to protect your cylinder head from rollovers.
High-Volume Air Filter
The ultra-low restriction air filter provides superior airflow and filtration for more power and long engine life. The inside of the filter mates perfectly to the carburetor to eliminate turbulence as air passes through the carburetor. The two-stage design features a reusable oiled foam element that's easy to maintain, and a built-in fine-mesh pre-filter.
