You haven't raced a really good "riced" out one. They were all show and no go. Your Expedition probably goes 0-60 in about 9-10 second range (if pre-2004). If newer it could be in the 8 sec range. There are some typical modified ones that could get to 60 in the 5 second range. You can make just about any car go really fast with the right mods. There is even a 1000 hp Ford Focus that someone built. They did this with the same 2.0 Zetec that comes from the factory. Obviously this was heavily heavily modified.
