WHY CROSS IT OVER
The "Lynx Crossover" is a unique induction manifold designed to obtain maximum efficency from a twin choke side draught carburettor on a 4 cylinder 4 port cylinder head.
Conventional manifolds connect venturi "A" to cylinders 1 and 2 and venturi 'B' to 3 and 4. When applying either of the typical four cylinder firing orders, 1234 or 1342, each venturi feeds 2 consecutively firing cylinders. This results in two induction pulses followed by two static periods.
The "Lynx Crossover" manifold is unque in that it connects venturi 'A' to cylinders 2 and 3 and venturi 'B' to 1 and 4, ie to alternatively firing cylinders. The "crossover" therefore spaces the induction pulses evenly. Seperated by static periods. It is in this situation that the side
draught carburettor was designed to operate effectively as with twin side draught carburettors where each venturi feeds only one cylinder.
