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 - Head Swaps

Q.
If I were to do a head swap, would the head be required to come off of a car on the VPI list?
Would I be allowed to use the stock header for the head for 0 points, or would I still have to use the stock header from the original engine? what would be the case if the original header does not fit the swapped head?

A.
When you pay the 100 points for a head swap, you can use any head you like. It does not need to be from a car on the VPI list.
Any OE exhaust manifold from the VPI list is zero points. Any aftermarket header is 25 points.
