ChampCar Tech Desk

Official channel for ChampCar technical questions, interpretations, and VPI requests.

Before you submit a ticket

The Tech Desk is for rules clarifications and technical questions. It is not a post race tech line, a place to protest results, or a place to fish for how other teams built their cars.

Most questions can be answered by reviewing the current BCCR Rulebook. Please read the applicable section before submitting a ticket.

If your question is already covered clearly in the BCCR, your ticket may simply be answered with a reference to the rulebook section.

VPI request checklist

For all Vehicle Performance Index (VPI) requests you must include:

  • Year, make, model, and trim level
  • Engine size and engine horsepower
  • Drive type: FWD, RWD, AWD, or 4x4
  • Transmission type: automatic or manual
  • Car weight and all factory options that affect performance
  • A link to the vehicle on automobile-catalog.com or another site with full specifications if it is not listed there

Requests that do not include all required info and research will be denied without review.

2020-01-09 - EuDM manifold usage

Q.
I have a 1991 Miata I am doing a complete 1999 driveline swap.

The European version of this vehicle has a different intake manifold than the US version. I planned on using this as it came with my driveline swap. I just want to be sure that the manifold does not cost points. Again, this is an OEM Stamped Mazda intake manifold.

A.
When paying SWAP points, to use the EuDM intake manifold you must be using a complete EuDM engine and must prove the engine is EuDm via a verifiable sales receipt with matching part number and serial number if the engine is stamped with a serial number.

If you cannot prove the engine to be a complete EuDM engine you may use the intake but must pay points for the intake as well as any other parts that are not from an OEM USDM engine.
