The VIPER uses ‘velocity air force' to direct cold air directly into the engine. The cold air feed takes air from behind the grill straight into the VIPER 's 100mm diameter inlet, swirling it through a unique Pipercross velocity filter contained within a carbon fiber heat shield, and then into a ram pipe to increase its pressure before feeding it into the induction system.
The carbon fiber heat shield protects the air charge from under bonnet heat keeping it cool - and therefore more dense - thus introducing more oxygen into the combustion mixture, giving increased power.
The reverse flow technology filter and 150mm ram pipe make use of the physical phenomenon of air tending to move towards surface areas, creating more air flow on the edge rather than in the centre of the inlet. The unique design of the filter cone and the inlet 'tune' the moving airflow to increase its speed and therefore its pressure maximising the laminar air flow into the engine, again resulting in increased power.
