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.

Q.
What are the width limits of an aero pan? Is it the extreme widths of the car like a wing? Is it the width or the rocker panels? Or is it the width of the punch welds?

A.
If you are paying points for non-oe rocker panels as an aero device or have OE rocker panels, the flat panel can be attached to, but not replacing the OE floorboards and extend horizontally to the vertical edge of the rockers. It cannot extend beyond the single plane vertical edge of the non-oe or OE rockers.

If you do not have rockers and are not paying points for aero rockers then the flat tray cannot be extended beyond the OE pinch welds.

If you are in doubt submit descriptions and photos of your flat tray mounting for approval to avoid surprise points at tech inspection.
