Race-oriented power and durability for 1/8 scale rigs

Designed to give a competitive edge, the O.S. Engine OSMG2075 30VG (P) combines a responsive midrange with usable high revs, making it well suited to 1/8 scale buggy and truggy applications. The engine's geometry supports a wide range of tuning setups for different track conditions.

Engine internals tuned for performance

The 30VG (P) features precision components that contribute to steady running. A rear-exhaust layout is paired with a machined aluminium piston for efficient combustion characteristics. The double-bushed tapered aluminium connecting rod lowers reciprocating weight, and the oversized, balanced crankshaft improves rigidity and reduces harsh vibration.

Features that reduce upkeep and heat issues

A rubber-sealed front bearing helps keep contaminants at bay, cutting down on routine strip-downs. The enlarged rear bearing increases load endurance, and the insulated carb sleeve helps prevent heat soak for more consistent performance through long race heats.

For racers and experienced hobbyists who want a dependable 1/8 scale motor, the O.S. Engine 30VG (P) balances durability and tunability for demanding track use.

Choose a clutch bell and shoe setup that match your vehicle weight and track layout, and set gearing to keep the engine in its strong RPM band without overrevving on long straights.
Yes, the enlarged rear bearing distributes load better and helps smooth out driveline vibration, which improves throttle feel and component life.
Tune the high-speed needle carefully while monitoring plug colour and head temperature. Incremental changes and short test runs help you find the optimum peak without risking damage.
For experienced builders wanting better midrange and sustained power, it is a worthwhile upgrade, but expect a learning curve for ideal tuning and break-in.
