The appearance of the BElls could be described as looking like a UFO, with two metal dishes joined together to create a Helmholtz resonance.
Intake systems described as 'Helmholtz Systems' have been used in the Chrysler V10 engine built for both the Dodge Viper and the Ram pickup truck, and several of the Buell tube-frame series of motorcycles.
