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.
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.
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:
Am I allowed to replace the flange on an exhaust manifold?
The stock flange design makes removal of the downpipe a bit challenging. I'd like to cut the flange off the manifold and replace it with a welded V-band flange.
This is "modifying the manifold" so I'm not sure this is allowed, but it is downstream of the merge
A:
You can change and use the clamping device of your choice on the end of the exhaust manifold..
