Engine Performance Additive Specification Example for Racing Teams: 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 racing teams is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — PU Leather, 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

  • gravity casting
  • heat treatment
  • ultrasonic cleaning
  • electroplating
  • CNC machining
  • assembly line testing

Where this example applies

Programmes that run racing spec most often specify this build for racing teams. Related applications include delivery vans, courier fleets, scooter fleets, camper conversions, boat trailers.

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

How long does sampling take?

Samples leave the factory in 10 working days, and each revision round adds about 3 days once you have seen the first piece.

How is packing specified?

Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.

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.

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.

Tell us the model, the fitment and the quantity and we will hold a production slot for you.
