7 Port Cylinder Heads

Product Description:

This Mini Sport 7 Port Cylinder head is a bare machined casting ready for you to build up and fit your own parts to.

* Optimises power on all Mini 'A' series engines, 998cc upwards, and excels on the larger capacity engines, 1380cc or even larger!

* Tested on a standard 1275cc engine fitted with 1.5:1 rockers, it increased the maximum power to 100BHP. This increase is due to the crossflow design and use of 4 inlet ports.

* Larger diameter inlet ports and crossflow design, overcome the 'A' series engines breathing problems, by increasing the inlet manifold air flow by as much as 20%, over an original 5 port head, fitted with the equivalent size of inlet valve.

* Cast from top quality iron, each casting is fully machined and pressure tested 'in house', in our very latest CNC machining facility, to ensure consistent quality.

* 1.2mm of extra space between valve centerlines, reduces the risk of cracking between inlet and exhaust when fitting BIG or oversized valves.

* The 4 port inlet manifold is cast as part of the cylinder head, designed to fit twin Weber/Dellorto carburettors, or injection throttle bodies, eliminating the use of a separate component.

* Retaining the original 3 exhaust port design, allows fitment of a wide range of LCB exhaust manifolds and systems without the need to purchase a special exhaust manifold.

* All A-series (standard or competition) cam and valve train components are used on the 7 port head to avoid extra costs of special components

* Each cylinder head is individually hand finished to many various specifications, from a bare head to a fully modified assembled complete head, or to a clients individual requirements.

* This 7 port cylinder head design, attained it's competition pedigree by returning many first class consistent results in Scandinavian events, and was used and fitted extensively by the Top Danish Team Works Minis.

Mini Sport have over 40 years of developing our exacting designs and techniques, whilst utilising the latest Flowbench technology and equipment, we have gained an unrivalled wealth of experience, which keeps Mini Sport as a recognised world leader of modifed performance

Each Cylinder head is accurately modified, firstly by CNC Milling machine to ensure consistency, then finished by hand. Each combustion chamber is specially shaped and balanced, each individual port is then gas flowed and finally the inlet ports are highly polished by hand to produce a consistently accurate modified product, guaranteeing the maximum percentage increase in air flow, so therefore increasing BHP and torque.
