Official channel for ChampCar technical questions, interpretations, and VPI requests.
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.

For all Vehicle Performance Index (VPI) requests you must include:
Requests that do not include all required info and research will be denied without review.
Q.
I would like to utilize OEM fuel injectors from a different vehicle (same brand & same year) which have a slightly larger lbs rating (30lbs to 39lbs) in an effort to solve my lean condition near the redline. Where would this fall under in 4.3.2?
A.
Fuel injectors are treated like carb jets - zero points.
