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.

2020-11-12 - Platform Swap and Engine Swap

Q.
We have a car that was platform swapped. Now we've done an engine swap from another generation leaving all the other swapped bits in place. Can we continue to claim the swapped platform VPI adding points for the engine swap or does the car revert to it's original VPI/platform?


A.
It should be valued as the highest valued model from its generation with an engine swap.  This does allow you to use OE parts from the highest valued model of its generation.

For example, A 1988 Honda Civic EF platform swapped to a 1988 Honda Civic Si now with a 1999 Honda GSR engine would be valued as a 1988 Si with an Engine Swap.  This car would be allowed to use the 1988 Si sway bars.
