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 - Dashbar Shape

Q.
Is it okay if the dash bar has any bends in it? I would like to curve mine forward from the A-Pillars slightly such that the bar runs right along the cowl/firewall. Photos are looking somewhat down on what the bar would look like. The factory dash bar shown would be removed or modified to allow the cage dash bar to sit flush with the top of the cowl/firewall.

A.
The purpose of the dash bar is to support the A-pillar bars from collapsing in on each other in an impact. By adding a bend to the supporting dash bar, you have introduced a weak point where the dash bar can fail. Such a weak link can be reinforced via a large gusset, but then this presumably defeats the reason for the bend in your bar in the first place - extra clearance/space. If the reason for the bend was to allow you to tie your dash bar into the cowl, then adding a large gusset or brace to the corners should not be an issue for you. If such a gusset were to be added, tech would be ok with the proposed design.
