Volkswagon R32
The standard Golf has never had such a powerful engine as the new R32. Its 3.2-litre V6 engine is a gem of German Engineering. The power output of the R32’s transverse six-cylinder engine is 240 BHP (at 6250 rpm) capable of 0.60mph in just 6.6 seconds.
The R32’s four-valve six-cylinder engine is distinguished by its very acute 15-degree V angle. Two overhead camshafts with continuous intake and exhaust camshaft adjustment are used in the cylinder head. The adjustment angles are 52 degrees for the intake camshaft and 22 degrees for the exhaust camshaft. The valves are driven by roller rocker fingers with hydraulic clearance compensation. Each cylinder has its own ignition coil.
From a technical point of view, the 3.2-litre V6 engine, with its crankshaft with seven main bearings, is of a similar concept to the 2.8-litre engine, which powers the Golf, Bora and Sharan V6. However, it has been improved in so many different aspects that it really ought to be regarded as a new generation of that engine.
Our gas flow measurements show that it has very good inlet flow but there was a lot of room for improvement on the exhaust side. After a challenging and extensive period on the flow bench we were able to raise the Inlet flow by 6% to 161.6 CFM. On the exhaust side we were able to make a huge increase of 30% to 129CF. This level of flow means this engine is capable of over 400BHP in normally aspirated form. (Turbo applications are popular on this head and we would expect over 800 bhp if this head were used with a turbo modification.)
Cost for this head is £1250.00 + vat on an exchange basis (Exchange £600) A ‘taping’ service is also available for this head at an additional cost of £100 which will give the final hand finish to the ports and provide a further 1% flow. This price includes valves.
Note : flow diagrams show flow against specific valve openings at 0.050 inch valve openings at 10″ pressure. Therefore actual flow volume increase is measured as the area under the graph (indicated in yellow for inlet and blue for exhaust). Standard valve sizes are used on our heads unless specified as a big valve version. Tests shown here are carried out on a flow bench on a bare head without filters. Therefore the difference between a standard engine with standard inlet ducting and filters will be larger than shown here.

Custom made Camshafts
With all of our gas flowed heads we also provide a custom made camshaft service. These camshafts are designed to optimise the flow characteristics of our heads. They can also be specifically designed to deliver the power characteristics you require for your specific application.Your existing camshaft will work with our heads, however, if you want to get the most from one of these heads or you have a particular power characteristic you are looking for, we recommend that you consider our custom camshafts.
Price £500 + vat
