The technology used in the VIPER was first seen on the Lotus 340R, but Pipercross are making it available for an ever increasing range of popular road cars.
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 fibre heat shield, and then into a ram pipe to increase it 's pressure before feeding it into the induction system.
The carbon fibre 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 physics involved may sound a little complicated but the increase in power using a VIPER against a standard air box will be immediately evident. Just as obvious will be the VIPER's stunning looks - the carbon fibre heatshield connecting the polished alloy inlet to the 150mm rampipe will be the focal point of any engine bay!
