Exhaust ports / Fresh-Air valves

DSPS Engineering produces the highest classes of motorsport stall valves and fresh-air valves used in the top motorsport series, and extreme street tuning applications.
DSPS products are known for their reliability and quality. Working closely and confidentially with OEMs and private teams, DSPS Wastegates and Anti-Lag are used where performance, quality and reliability are important.
Since 1986, DSPS products have won numerous races and championships worldwide, competing in the highest levels of motorsport in the world – F1, Indycar, Le Mans, DTM, SGT, GT3, IMSA, WRC, RallyX, Supercars and Hypercars.
Our motto is Quality Driven Performance – DSPS is obsessed with quality and it drives everything we do – from individual components to the finished assembly itself, from packaging to communication with the customer.
The core philosophy remains as important now as it was when DSPS started – do it once, do it right.   All DSPS products are designed, manufactured, assembled and tested in the UK.
In fact, DSPS uses a ‘zero defect’ Total Quality Management (TQM) process throughout the company, allowing for complete traceability from raw materials to assembled product.
All DSPS assemblies are assigned a unique service life number during the build process, meaning that parts are managed throughout their life, regardless of where in the world they are located, and under the specified operating conditions.
DSPS has been supporting customers for over 30 years with race-winning products.
