O.S. Engine 21VG (P) Mid-Range Competition Engine  [OSMG2058]

Unlock Better Driveability with the O.S. Engine 21VG (P)

When preparing a 1/8 scale Ready-To-Run model for ROAR competition, the O.S. Engine 21VG (P) provides a reliable upgrade path. Many factory-fitted units do not deliver the controlled mid-range power needed for competitive racing, and the 21VG (P) addresses that gap with consistent, race-ready performance.

Mid-Range Focus for Better Cornering

The 21VG (P) delivers dependable mid-range torque that improves corner exits and lap-to-lap consistency, making it attractive to drivers who value traction and predictability over extreme peak revs.

Engineered for Longevity and Ease

Key components such as the ABL piston liner simplify running-in and extend service life, while the one-piece crankshaft and rear exhaust layout support reliable off-road operation and steady power under load.

Simple Tuning for Club and Race Use

With a straightforward 2-needle carburetor the 21VG (P) keeps tuning accessible for less experienced drivers while still allowing fine adjustments. The wider Tornado head takes a standard glow plug for easy, cost-effective replacements.

The O.S. Engine 21VG (P) is a practical option for racers seeking improved mid-range driveability and low-maintenance tuning for a variety of 1/8 scale platforms.
