There is one key element missing in these. If you place something on the shield, over the flames the symbolizes an engine. Either a silhouette of a V8 engine, a silhouette of a Top Fuel Engine. crossed pistons, exhaust headers, ANYTHING that would identify the logo with engines. Then this would be the one we choose. We like everything else about it (them) The colors. graphics, etc.
I should have been more clear.... I wanted something in front of the flames, over-layed, that symbolizes an engine or engine parts. Whatever you did on your latest versions is too small for me to see.
I also asked logotournament for an extension of 3-days. Thank you.
