ChampCar Tech Desk

The tech desk is used to ask technical questions and is not to be used as a post race tech line or to phish for how others built their cars. Please reference the BCCR as most questions submitted to the TechDesk can be answered by reading the BCCR. You can download the BCCR here: https://champcar.org/web/rules.php
VPI requests require the year, make, model, trim level, engine size, engine HP, Drive type (FWD, RWD, AWD, 4x4), auto or manual transmission, car weight, and all options. Your request will not be answered if you do not include all of that information. You must use http://www.automobile-catalog.com for all of your information submitted. Include the link to the automobile catalog so we can quickly reference the data. If your car is not listed on that website, please link any website that has the info. If you do not include your research info above, your request will be denied.
Thank you.
