Design and Manufacture
1000 BHP capacity utilising
the latest in computerised testing facilities
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
We are proud of our craftsmanship, and hope that you are
able to share in that pride.
