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.

2023-02-26 - Multiple Fuel Cells

Q:
ChampCar 2023 BCCR-9.10.4.1 "Stock fuel tanks in stock locations OR approved fuel cells are the only fuel sources allowed for competition". The wording of this rule reads as "cells" (plural) being acceptable.
Detailed ruling - 9.10.5 (Fuel Cells) does not specify an allowable total number of fuel cells.

Please review and provide approval/feedback on the scenario below.
Car A has the stock fuel tank mounted behind the driver / in front of the rear wheels and it has a saddle that straddles the driveshaft.
We would like to mount one fuel cell on each side of the driveshaft (total of two) to retain the factory fuel location. We will also retain the factory single fill location, capacity requirements, bulkhead requirements and all other rules laid out in the "9.10 Fuel System" section.
Is this installation of two fuel cells acceptable (provided all requirements laid out in 9.10 are met)?


A:
NO.  Only a single fuel cell is permitted.
It is worded cells because no specific manufacturer, part or cert number is demanded.
