Cylinder Head Porting

This is the specialised proces of modifing the inlet and exhaust ports of the cylinder head, to inprove the quality and quantity of gas flow. Porting technology is responsible for the high power output of modern engines, more than any other single factor.

The FW Developments hi-tech workshop contains a gas flow bench, where extensive testing is used to produce the basis of optimum modification.

FW Developments uses its 20 years of experience and expertise to ensure that the best quality product is achieved, through the craft and skill of legendary tuner, Frank Wrathall.
