Nova B5R EVO Nitro Engine Combo

Win this B5R EVO Nitro Engine Combo, Oil Bathed by Answer RC (This engine was used twice by my daughter, has been ran in rich and still needs leaned out for the final tune, has 8 tanks total through it including 2 at idle on the starter box) Includes a Nova Exhaust, manifold and spares. EFRA 2182

NV-5002012 NOVA B5R EVO .21 5-Port Buggy Engine w/Steel Bearing & DLC Crank

Nova’s latest range of EVO specification engines represent a culmination of feedback from both users and team drivers alike, to further refine the engines to offer drivers with the best performance, efficiency and engine longevity. This has been achieved with extensive testing, optimising both the materials used in manufacture and also the design of the engine.

We are confident that you will love the new EVO specification engines and we expect to see them at the top of podiums throughout 2024 and beyond.

NOVA Off Road Exhaust Pipe 3.5cc EFRA 2182

NV-2002001 NOVA Off Road Exhaust Pipe 3.5cc EFRA 2182

The Nova 2182 pipe makes the perfect choice for use with their own .21 Off-Road engine range, as it was specifically designed to optimise power output and fuel effieicncy whilst providing a linear feel on the track for the bets drivability.

The pipe does not come supplied with a manifold, which allows you to chose between either the 50mm or 55mm, this allows you to tailor the powerband to suit your personal preference or the track size. As a default choice for 1/8 buggy, we recommend using the NV-1902001 50mm Manifold for use with the .21 B3/B5/B3R/B5R, this provides a linear power delivery, great top end performance and good fuel efficiency. Should you be running on a tighter track, or simply want more bottom end, we would recommend the NV-1902002 55mm Manifold – This also makes a great choice when using any of these .21 buggy engines in a 1/8 truggy where more torque is best to move the extra weight.

Manifold length impacts .21 nitro engines by affecting exhaust pressure waves. Longer manifolds create resonant waves that boost low-end torque by improving intake efficiency and scavenging. However, this creates backpressure, limiting high-RPM power.

Shorter manifolds offer less backpressure for improved high-RPM performance but sacrifice low-end torque. Choose the length based on your needs: balance (mid-length), low-end grunt (longer), or high-end power (shorter). Remember, this is just one factor in engine tuning, and experimentation is key.
