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.

2020-03-20 - Bumper Structure Replacement

Q.
2020 requires "bash-bars" to be added if the car no longer has the OE bumper structure. When these are fabricated:

- Is there a minimum size/wall thickness required?
- Are bash-bars counted for points?
- If yes, then how are points calculated?

A.
2020 rules require the factory bumper reinforcement bar or a roll bar minimum .095 thickness or comparable beam be used across and connecting frame horns on both the front and rear of the car. Rear must be substantially reinforced to offer adequate protection to the fuel cell or OE tank.
No point add as these are now required.
