The power for climbing. The speed for racing. The engine for both.
Torque — or speed. Time was that an 1/8 scale engine was designed for one or the other. However, monster trucks and truggies need both — and that requires the O.S. 30VG.
With its virtually perfect balance of bore-to-stroke, the 30VG offers unrivaled adaptability for 1/8 scale and the perfect power plant for almost any application. Put it in a monster truck or truggy and it excels. Put it up against .21s, .25s and .28s, and it blows them away in big-block performance — and drops into the spaces they occupied for easy, no-mod retro-fits.
Engineered for 1/8 scale — designed and tested for O.S. dependability on-road or off.
- Available in three SG-crank versions, including a recoil start model and an SR model purpose-designed for the HPI Savage.
- Rear-exhaust design.
- Machined aluminum piston.
- Double-bushed, tapered aluminum conrod for minimal wear and weight.
- 3-port liner.
- Oversized balanced crankshaft for added strength and smooth, vibration-free operation.
- Rubber-sealed front bearing reduces teardowns — enlarged rear bearing minimizes vibration and improves load-bearing capacity.
- Insulated carb sleeve prevents heat-related vaporization and predetonation.
- Rubber shaft boot preserves smooth, easy slide-valve operation.
