Rally2/R5 Homologation Pop-Off Valve Scrutineering Procedures

The Motorsport UK Rally2/R5 Pop-Off Valve Scrutineering Procedures provide technical guidance for scrutineers checking homologated or formerly homologated Rally2 and R5 vehicles. On this page, you can access guidance on the applicable regulation references, the parts involved, including the FIA Boost Control Pipe, insert and Pop-Off Valve, and the checking equipment used during scrutineering.

The document also explains the pre-event checking procedure, visual inspections, valve stroke checks, sealing requirements, controls during an event, and post-event scrutineering, including when a Pop-Off Valve may need to be returned for pressure testing.
