Components are designed in house using the latest computerised techniques. Many of these items are also machined on the premises. Uniquely therefore we can pursue a continuous development programme to maintain our status within the industry, without having to resort to buying in components based on old technology.

Every engine is hand built. Whether it be for circuit racing or for road use, the same exacting standards and procedures apply.

New engines are run for up to five hours on our computer controlled dynamometer, and then fully power tested with all variables being uniquely adjusted for your engine in order to guarantee top performance and reliability. Finally, and only if the engine meets the stated power output, the engine is subjected to a final inspection prior to sign off.

Each engine is supplied with a hard bound manual containing full operating instructions, power curves and other useful installation tips.

We are proud of our craftsmanship, and hope that you are able to share in that pride.
