Description
 

This is the Traxxas TRX 3.3 Racing Engine with Pull Start.  This will give your Revo, T-Maxx 2.5, or Jato an unbelievable boost in performance.  This is a must have upgrade.  You can also use this with the factory EZ-Start.  These are a direct bolt-in upgrade for any 2.5 or 2.5R powered Traxxas vehicle, and they are a direct replacement for any current 3.3 vehicle.

FEATURES:

  • For use in all Traxxas TRX2.5 and TRX 3.3 equipped vehicles
  • Pull starter can be removed to install the EZ Start
  • 60% more peak power than the TRX2.5, with nearly 50% more power under the curve for strong linear acceleration
  • Round rear exhaust with one-piece IPS crankshaft
  • Composite body slide valve carburetor witt high-volume air filter
  • Blue anodized aluminum cooling head with molded head protector

Traxxas TRX racing engines are fueled by a passion for performance, innovation and quality. Traxxas engineers are dedicated to redefining the state of the art in engine technology. This includes listening to our customers, and developing new standards and conventions that would meet the performance challenge.

The TRX 3.3 Racing Engine™ draws from a legacy of precision Traxxas engine design and manufacturing. Traxxas has always been at the forefront of innovation, beginning with the powerful and reliable TRX Pro.15. Next, the Traxxas EZ-Start™ system ushered in a new era of convenience and ease of use with true, push-button electric starting. EZ-Start later evolved to incorporate built-in diagnostic functions, LED indicators, a constant-voltage glow plug circuit, and more powerful starter motors. Then came the TRX 2.5, a marvel of award-winning power and technology that sent the bar for Ready-To-Race® performance to unimaginable new heights.

Fast forward to the present and 14 years of nitro engine development have culminated into the most powerful TRX engine ever made, the new TRX 3.3 Racing Engine. It embodies everything we’ve learned from over a decade of making engines more powerful, more reliable, and easier to use. The TRX 3.3 Racing Engine is so powerful it establishes a whole new classification of powerâ¦. Extreme Power!

The TRX 3.3 produces an extreme 60% more peak horsepower compared to the TRX 2.5! The overall power under the curve is nearly 50% greater to deliver the smooth, linear power output TRX engines are famous for. The TRX 3.3 Racing Engine offers thoroughbred race engine performance that’s absolutely second to none. There’s no penalty to pay for having more power either. The TRX 3.3 Racing Engine is equipped with EZ-Start push-button electric starting and simple, reliable tuning from the two-needle composite slide carburetor.

The TRX 3.3 Racing Engine is truly the pinnacle of power and reliability and represents the commitment to total performance Traxxas carries to the customer.

TRX 3.3 Racing Engine Parts Descriptions:



Piston and Sleeve
The lightweight reciprocating assembly allows higher revving performance and reduced 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) were selected for their 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 new 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. Traxxas IPS crankshaft design makes the TRX 3.3 compatible with any model equipped with a TRX 2.5 or TRX 2.5R Racing Engine.

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.

Push-Button Electric Starting
The Traxxas EZ-Start is a hallmark of Traxxas Engines. The Traxxas EZ-Start ushered in a new generation of electric starting and today it is still the safest and most convenient solution, delivering on the promise of true, one-handed, single-button electric starting. In an instant, EZ-Start lights the glow plug with a powerful constant voltage circuit and spins the engine. Built-in diagnostics alert you if the glow plug has failed and monitors the starter motor for the most reliable, troublefree engine starting possible.

TRX Composite Slide Carburetor
The TRX 3.3 is equipped with same high-performance slide carburetor that has reliably powered a generation of TRX Racing Engines. The slide type carburetor provides less restrictive, straight through airflow for more power and improved throttle response. Because it is molded, Traxxas engineers incorporated superior internal design enhancements and precision not possible with traditional machined carburetor. The composite material does not transfer heat like aluminum for more consistent tuning.

 

Crankcase
The TRX 3.3 uses a new 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. The external dimensions allow the TRX 3.3 to fit anywhere a TRX 2.5 or TRX 2.5R was installed.



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. There are other rear exhaust engines, but 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 newly designed molded head protector is securely fastened to the top of the head with precision hex screws.

Head Protector
Theimpact 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 air filter is often overlooked as being a key to engine performance and life. Not so with the TRX Racing Engines! It's ultra low-restriction air filter provides superior air-flow 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.
