The only thing I can think of that comes close is the Cerbera Speed 12 test mules. They were still 2200# but they put the engine on a 1000hp test stand and broke the input shaft. The owner, a Mr. Wheeler I believe, drove one home one night and before he got 300 yards decided that the cars would kill someone and decided to cancel the program. Wilf can probably get a little more info on this, I read the interview in a British magazine.
