Show Us The Best Production Engine You've Ever Heard In Real Life

Whether it was on a track, though a mountain pass, or while drinking coffee and looking at cars, loosing your Earginity (yup, I went there) is a big moment in an automotive enthusiast's life. The strange thing about Earginity is that you can loose it more than once, and to an even greater degree!

If you can't pick, show us your first.

Side Note: Someone here took this picture, but I can't remember who; please tell so I can praise you for it.
