OK, I was going to suggest a funny one, but some on here are pretty sensitive, take themselves too seriously, and/or have a phobia. So ...
Alabama Compression Ignition Truck Club, or some such variant. I still say we should keep the name more neutral so we can let our Ford & Chevy buddies share the cost of dyno events!

And maybe a name that doesn't make us sound like like knuckle dragging inbred mouth breathers.
