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.

Is a removable gurney flap additional points?
Is a removable second or third element (which increase the effective chord of the main element) additional points?

Is a permanently affixed (riveted, welded, or epoxied) gurney flap additional points?
Is a permanently affixed (riveted, welded, or epoxied) additional element (which increase the effective chord of the main element) additional points?



A.
Included in 10 point wing = uprights mounts, end plates, blade.
Endplate limits = at this time we do not have size limits, the endplate has to mount to the blade only and this should stop any ridiculously large endplates. 
Can a wing be forward of the rear axle centerline = No
Can the wing be adjustable = Yes. While on track = No. Moveable on track = No
Gurney flap that is attached across the blade of the wing, removable or changeable off track, = included
Additional element = if attached across the wing blade included
Attached definition = if we can slide a piece of paper anywhere between the wing blade and the additional element it is a separate piece and will be an additional 10 points for another wing. The rule states Wing 10 points = 1 wing.
