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.

2020-02-27 - Reinforcement due to damage

Q.
We suffered a failure at Road Atlanta of our CV joint. This caused the output shaft pulling out of the diff and the subsequent thrashing of the CV Joint and output shaft caused our diff mount to fail on the differential. After removing the subframe we were able to bend the chassis mount back to mostly normal placement. We are worried about the metal fatigue and would like to reinforce this chassis mount. What are our options? Add metal close to original thickness?

A.
Repair the damage with like size material. Make a note in your car info book that the new material was to repair damage keep photos of the damage and the repair.
