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.

2020-01-05 - Patching floor for roll cage

Q.
We had to patch a rust hole in the floor where the main roll cage hoop box will mount. Is this considered safety-related for the cage? Or accounted for material used?

A.
This is covered in BCCR 4.7.6 in the rules. (BCCR 2020v1)

4.7.6. Teams may replace any worn, broken, ventilated, impaled, defective, or bent-beyond-all- recognition parts on their car without affecting their total points so long as it’s an OEM or OEM- equivalent part for that car’s specific model.

4.7.6.1. Teams may repair/replace rusted/fatigued/damaged portions of the chassis with similar thickness metal or OE-approved repair components/methods. Repairs must maintain some likeness to the original body lines of the
chassis.

Now the patch cannot be used as the base plate for the cage roll hoop. We would like the base plate or plinth box to extend beyond the patch for added strength
