About AP Engines

AP Racing Engines Limited operates as a specialized, family-run enterprise focused on the construction, development, and tuning of high-performance race engines. With a heritage spanning two generations involved in motorsports, the company has established a significant track record across a wide spectrum of motorsport disciplines, including International Rally, Autograss, Drag Racing, Touring Cars, Sprint, and Drifting. The firm serves a global clientele of motorsport teams and privateers, providing engines and products for various competitive formats.

The core of the business revolves around bespoke engine builds and precision tuning. The company possesses extensive experience with a variety of well-regarded engine platforms such as the C20XE (Red Top), Cosworth YB, Duratec, Pinto, and X-Flow, among others. Revenue is generated through these custom engine building and rebuilding services, tailored to either specific customer requirements or regulatory rulebooks. A key service is their advanced engine tuning, conducted on a modern rolling road dynamometer capable of measuring up to 600 BHP. This facility allows for the creation of 3D mapping to refine engine characteristics and simulate real-world conditions like wind or road incline, providing clients with detailed diagnostics and performance outputs.

A distinguishing feature of their service is a deep focus on port technology, which the company identifies as fundamental to maximizing torque and power. Their process involves airflow testing on all cylinder heads to ensure optimal design and performance, emphasizing that the shape and design of the port are more critical than sheer size. In addition to engine building, the company specializes in ECU mapping for a wide range of popular aftermarket systems, including DTA, Omex, and MBE. Every tuning session includes a comprehensive health check to ensure the vehicle is safe and to offer advice on potential performance enhancements, catering to a diverse range of vehicles from classic and vintage road cars to dedicated race cars.
