Engine Performance Additive Specification Example for Export Programmes: Racing Spec

This is a worked specification for engine performance additive in a racing spec programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The racing spec version exists because the duty cycle on export programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually reorders that did not match the approved sample.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Zinc Plated Steel, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • ultrasonic cleaning
  • shot blasting
  • anodising
  • die casting
  • gravity casting
  • laser cutting

Where this example applies

Programmes that run racing spec most often specify this build for export programmes. Related applications include agricultural trailers, assembly programmes, utility trailers, dealership service, export programmes.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 1.5 sampling on the finished lot.
  • Finish inspection under agreed lighting.
  • Carton drop test on the first lot of a new packing specification.

Questions buyers ask

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the DOT-compliant build instead of a fresh interpretation.

Can you match an existing sample?

Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.

What testing is included?

Standard lots ship with dimensional and hardness reports. DOT documentation is issued with the shipment when your market requires it.

How long does sampling take?

Samples leave the factory in 14 working days, and each revision round adds about 3 days once you have seen the first piece.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
