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:
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 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.

2020-11-12 - Platform Swap and Engine Swap

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?

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.
