we pretty much already have one! the race section.

if I have a general question about my car or any other mechanical system, I go to the tech forum, lots of guys there who have restored more cars thatn I'll ever own, and can answer those types of questions.

if I have a motor question, I'll go to the Race section, we have LOTS of engine builders, and racers who build their own engines in the race section.

Never failed to get an engine question answered there.

In fact, lots of good smart guys in the race section who know a lot about setting up suspensions, axles, engines, custom modifications, etc.
