CPL Racing CNC Ported Cylinder Head - Mini / JCW Cooper S (2nd gen) N14 N18 Engine

Product Information

CPL Racing CNC ported cylinder head service for Mini / JCW Cooper S (2nd gen) N14 and N18 engine

At CPL Racing we have been porting cylinder heads for 20 years. Our recent acquisition of a new 5 axis CNC machining centre however, has allowed us to expand our services further into CNC ported cylinder heads. Unlike any other company, we do not digitise hand ported heads and reproduce them by CNC machining.

Our process is a completely new approach which begins by digitising the stock head. Various ports are then designed using computer aided design (CAD), using formulas we have developed over many years complemented by our extensive knowledge in this field. The various ports are then machined into stock heads and tested for both flow and velocity on our computerised flow bench. Once the optimum port has been designed and tested it is then offered for sale.

The N14/N18 cylinder head is of particular interest to CPL Racing. It has a huge amount of potential and the engine is considerably restricted by the bottleneck evident within the stock head. The N14/N18 CNC cylinder head we have developed offers substantial gains in flow without sacrificing velocity.
