Well the mph is a little fast for 12's and it could be possible to run what he is saying but I doubt it. Its more fun if you keep them going though
On a side note, I was working on an F450 earlier and a guy commented towards the owner of the truck about it having a really big motor. I looked and the hood was closed, thought maybe he knew what was in it anyways. He carried on a little bit then said something like, "Man, a 450, that motor is huge!" I just smiled to myself
