Elise Airbox and trumpet kit for high performance use

This product was developed on the Emerald rolling road by Dave Walker, Steve Butts and Bernard Scouse.

It was developed to improve the mid-range torque of the engine to increase acceleration out of corners and make the engine less "buzzy". Due to the timing of the ram effect of the pulsations in the intake tract long trumpets give good power low down but restrict the top end, short trumpets have the opposite effect.

Many road cars and some F1 cars utilise this ram effect by having variable length intake systems to spread the effect over a wide rev range but not practical or economic to achieve without a huge budget.

By optimising the length of the trumpets on a bank of cylinders then gains could be had at the mid-range without compromising the top end significantly.
The result is that inner and outer cylinders can run different length trumpets depending on your power optimum
After 3 days of rolling road time we came up with the airbox and trumpet arrangement below.
