Bailey Motorsport began 15 years ago preparing race engines and cars for various levels of Motorsport and fast road use.

They were heavily involved in the tuning of the Cosworth YB engine as fitted to the Escort and Sierra Cosworths and produced many race and championship winning cars. Competing at top levels gave them invaluable information on what parts worked and what didn’t.

These early days of rolling road tuning, engine building and exhaustive testing both on track and road led them to develop a range of alloy oil and water tanks and later dump valves that could out-perform and outlast the competition.

The word spread and there ‘tanks’ & ‘valves’ soon become essential kit for people serious about their cars looks and performance.

When Bailey introduced our revolutionary ‘Piston’ dump valves in 1997, this marked a move in direction from engine tuning to full time alloy CNC machining and fabrication to keep up with demand.

Although they no longer prepare or tune cars, they still develop products at their Hertfordshire base and work with many engine builders, rolling roads and tuning companies to make sure that there products perform to their optimum.
