NV-1902001 NOVA Off Road Manifold 3.5cc 50mm

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.
