You're about to witness the "scariest thing" ever done in Jay Leno's Garage: the extraction of a McLaren F1 supercar's V-12 engine.

Well, you don't actually get to see the extraction process, but you do get to see the engine on the stand, with some nice detail shots and info from Jay himself. There's even a peek around the vacant engine bay.

Go ahead, get up close and personal with the thumping BMW-built heart of that car that lived on your wall 20 years ago.
