MEG2855
Precision-machined 8.0mm venturi insert (MEG2855) for Mega SX-21 carburetor, optimizing mid-to-high RPM airflow and fuel atomization for explosive top-end power in 3.5cc nitro racing engines.
Track based tuning and fuel economy with the genuine Mega SX-21 8.0mm Venturi Carb Insert (MEG2855), precision-engineered for Serpent Mega SX-21 3.5cc nitro engines in competitive 1/8 scale off-road racing. CNC-machined from lightweight aluminum, this venturi restricts intake to 7.0mm—ideal for low-traction tracks where power of the corners with no loss of straight-line speed dominate. It enhances venturi depression for superior fuel draw and atomization at wide-open throttle, delivering crisp throttle snap and extended power band without sacrificing low-end response. A must-have for tuners chasing maximum drivability.
