Our heads don’t feature just 1 port suits all, all our porting is done in collaboration with our customers to suit their setup. Our ports differ between turbo, n/a, 1600cc, 1800cc setups etc. Port shape, throat size etc is all calculated based on your requirements and to suit your application, Drag racing is completely different to rally or circuit racing.
Our heads not only feature high CFM flow but Port velocity is what we concentrate on especially, this is how we obtain good overall power through the entire rev range, not just peak power.
