I've only heard one once a long time ago, and yes it sounded really cool. And after I got over the sticker shock, it occurred to me that it would be some serious bragging rights. It would be a good reason to shut off the truck when you go to a dyno meet.

You cannot explain or explain away the power of God.
The fleet where I worked had some air starters many years ago but proved to be troublesome and expensive. Where fire safety is a concern or mandated that non electrical equipment be used may require air starters.
You know how an impact wrench sounds? Its kinda like a cross between and impact wrench and a singing turbo.... Louder and higher pitched than an impact and louder and deeper than your turbo. Sharp and crisp sound.
The ones used for those monster 3512's is deafening...
You will never forget what one sounds like when you first hear it go off. I hit the deck because I thought the SOB was about to blow-up, all of the experienced hands laughed at me :-/
Air start systems work well on large (very, very large) diesel engines that a starter motor could not turn over.
The air start system pipes high pressure air to each cylinder from a distribution manifold and though air start check valves to each cylinder. The systems I'm used to run with 175 psi starting air pressure and will spin a diesel engine until it starts.
After maintaining the air start systems, I'm glad that my truck has a starter motor....
