Traxxas TRX 3.3 multi shaft racing engine is for use in all Traxxas TRX2.5 and TRX 3.3 equipped vehicles with flywheel access 60% more peak power than the TRX2.5, with nearly 50% more power under the curve for strong linear acceleration. Two threaded crankshaft inserts for "short" and "standard" applications. Rear exhaust. Molded LCP (Liquid Crystal Polymer) body slide valve carburetor with high-volume air filter. Blue anodized aluminum cooling head with molded head protector .
Some notes on slide valve and rotary carburetors. Rotary carbs offer a larger response in the middle of the power band. This works well for off-road applications when throttle response must be varied. Slide Valve carbs provide greater response at the beginning and end of the power band. This works well for on-road and racing applications for fast take-offs and high speed.
