Mistral Velocity Stack - Moto Guzzi V85TT E4/E5/E5+

Mistral Velocity Stack specific for Moto Guzzi V85 (all versions) Euro4, Euro5 and Euro5+.

What is the Velocity Stack?
The Velocity Stack is a high-performance component, conical or cylindrical in shape, placed between the airbox and the throttle body. Its main function is to optimize the airflow entering the engine, improving overall efficiency.

Performance and Benefits
Thanks to its carefully studied geometry, the Velocity Stack improves the engine’s volumetric efficiency, reduces turbulence and optimizes intake pressures. This results in a quicker throttle response and an overall increase in performance.
Parameters such as length, taper and diameter directly influence power delivery: a correct balance of these factors allows a real performance boost.

MISTRAL Version
The Mistral Velocity Stack was specifically developed for Moto Guzzi V85 Euro4, Euro5 and Euro5+. Later, using specific software to analyze airflow relative to intake pressure, we optimized the shape and size by defining several prototypes.
These were 3D printed and tested on our dynamometer, analyzing torque, power and rpm results. This process allowed us to identify the most efficient configuration.

The Mistral Velocity Stack has shown excellent results throughout the entire power curve, even at low RPM the engine feels more responsive and reactive, and around 3500 RPM, where the bike typically dips, we achieved a gain of +1 hp and +1 Nm of torque. As revs increase, improvements continue, reaching a maximum gain of +2.3 HP and +3.5 Nm. To maximize performance, we recommend pairing it with the Mistral Air Filter and the Vtwin Boost.
