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.

2020-01-30 - Non-OE Cylinder Heads

Q.
Car: 1986 Ford Mustang LX with 5.0 V8

Per 2020 BCCR: "Cylinder head(s), non-OE and/or non-matching to your specific engine claimed. 100 pts per engine."

* Does this rule mean installing GT40P heads from a 1997 Mercury Mountaineer incurs the 100 point penalty?
* Does this rule also permit aftermarket aluminum heads in place of cast iron for 100 points?

A.
The 1986 5.0L Mustang was never offered with GT40 heads. The GT40 head made its debut in the 1993 Cobra and was offered on the following vehicles:

1993-1995 Mustang Cobra - Part #F3ZE or #F4ZE
1996-Mid 1997 Ford Explorer & Mountaineer SUV - Part #F1ZE-AA
1993-1995 Ford F-150 Lightning - Part #F3ZE or #F4ZE

A GT40 head on any LX or GT Fox body Mustang would incur 100 points for non-stock cylinder heads.

However, you can use any aftermarket cylinder head for the same 100 points. Trick Flow, Fox Lake, Edelbrock, etc.
