Polini Motori have a new addition to add to their exhausts range with a new EVOLUTION 3 exhaust system developed to achieve max power from liquid cooled Minarelli horizontal engines.
This exhaust has been specifically designed for use with 70cc Evolution cylinders. The features are as follows:
- Completely hand made.
- Exhaust manifold flange with three holes to couple perfectly with the new cylinder and avoid possible gas escaping and power loss.
- The manifold has been connected with a turned pipe to achieve the Venturi effect and improve the quantity of the gas scavenging consequently producing a power increase up to 14,000 rpm.
- The visual look and the exhaust's dimensions have been studied to give the maximum yield when used with the TORSEN WD.
- The silencer curve can be disassembled; it's possible to insert nozzles of different diameters to increase engine revs.
- The silencer, made of black anodised aluminum is slightly longer to contain noise and varies in the internal diameter which is larger to improve acceleration.
- The base is detachable to change the deadening material.
All these features improve the general engine performance; both in
acceleration and in speed, for a fun ride at the circuits.
