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.

2021-01-02 - Alternator Mount

Q.
I removed the smog pump and then had to make a new upper mount for the stock alternator. I used some steel, one long bolt ad then a left handed adjuster (not a heim joint). I used the left handed adjuster only so I didn't have to use a prybar to adjust the alternator. There is less than 6 square inches of materials used. Is this points? Thanks for the help!

A.
There is no points for the bracket and adjuster. Updated by TECH 5-7-24
