I recommend using Imgur to upload your screenshots, as it would reduce clutter in the forum with big images everywhere.

Have fun!

There are a lot of restrictions, I expect people to get very similar results with this.

There is another thread like this that I think will appeal more to people as the only restriction is the car's aspiration: viewtopic.php?f=34&t=3376&hilit=best+economy Maybe putting them in a leaderboard in the first post might help attract people?

I was mostly thinking that the restrictions would spark some creative designs, but I'll remove some of the restrictions then.

You don't have to change the rules just because of my personal thoughts, and you make a good point with your restrictions provoking people to think more of their designs.

I'll keep most of the engine related restrictions, as those are the more important ones anyways.

what about man hours restriction on the engine?
