Mistral Velocity Stack

Measurements and results Velocity Stack for V85TT

Mistral Velocity Stack is our specific product for increase the volumetric efficiency of the engine by providing in more air. It reduces turbulence and improves the engine response at throttle opening. The result is a clear increase of the performances.

The product is completely studied and designed with CAD3D and then with a specific software to analyze the air flows in relation to the intake pressure. After the realization of some initials prototypes with 3D printer, the final product is completely machined from solid with the best technologies on the market.

During the development stage, there were performed a lots of tests with our test bench in order to obtain the best result in terms of power-torque. The two following charts represent what has come to lights: an excellent result on the entire power/torque curve, from the very first rpms the bike results much more responsive, even at 3500 rpm where it suffers more we were able to obtain + 1cv of power and + 1Nm of torque, then increasing the revs the gain increases both in terms of net power and torque, while the maximum net gain is more than 2 HP.

Beyond the results that we obtained trough the research and the tests, we constantly receive feedbacks from our costumers and following we want to leave a review that we recently get.

A costumers of ours from Germany decided to do some test on his Moto Guzzi V85TT Euro5 to verify firsthand the performance of our Velocity Stack. Through the application of a specific app (Phyphox) he accomplished some measurements before and after the installation of the product. It comes to light, as noticeable in the results in the following charts, a visible increase of the performances.

In this article we focused on the results of the product fitted on a Moto Guzzi V85TT. Mistral Velocity Stack is also available for per Moto Guzzi V7 I (single throttle body), V7 II, V7 III, Nevada 750 i.e. (original flat exhausts), V7 850 Euro5, V9 Euro4-Euro5 and for Royal Enfield Continental Gt 650 Euro4-Euro5, Interceptor 650 Euro4-Euro5, ShotGun 650 and Super Meteor 650.
