It looks like the Caterpillar 3406A from the Revell USA snap kits (take your pick, they used the same engine). The engine is 883 cubic inches, and is rated from 250 to 402 hp. Three turbos seems a little excessive to me.
Can say as I've had that happen before. One of them did clear the bench while chasing something before, and I have one helping me type right now. Well, he thinks he's helping!
