Traxxas TRX 3.3 Racing Engine

Traxxas® TRX 3.3 Racing Engines

Features

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 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.

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.

60% more peak horsepower than the TRX 2.5

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.

TRX High-Volume Air Filter 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.
