Cylinder Head Conversions And Blue Printing

Racing is in our DNA, we have been racing and building race cars and or heads for years and years and we can proudly say that we have more than 50 years of accumulative race cylinder head knowledge. All our staff on the floor have petrol and diesel flowing in their veins – we are passionate about increasing performance and building good cylinder heads.

The technology in manufacturing and production of motor vehicles are moving forward fast but mass production is still the order of the day in modern car building. This means that there is still plenty of room for improvement around performance enhancement especially in the cylinder head.

We are able to build cylinder heads from mild street to full blown race – it all depends on the requirements. We gather information from our clients regarding the vehicle, the application and personal requirements and carefully formulate a plan that suits the needs. So if you are looking for an upgrade on a road going vehicle or a full blown race head, naturally aspirated or forced induction – we can help.

There are a number of aspects to keep in mind in blueprinting or building a good performance cylinder head, it is all about volumetric efficiency, combustion efficiency and of course cylinder and combustion chamber sealing. Valves and camshafts play a big role as do valve spring pressures, valve guides, valve spring travel, valve lift etc. We use the best technology available to optimise all of these functions and more.

Each application when considering a cylinder head conversion is very different, towing, drag racing, drifting, spinning, oval track racing, rally cars etc. mention only a few. Call us to have a chat about your needs.

One very important thing to remember when building performance cylinder heads is that the best head available in the world will be worth absolutely nothing if the head is not assembled, installed and tuned by a similarly qualified person. We can give advice in this regard.
