My guess is the Bugatti EB110, with 542 HP in 1991. Am I right?

Since when was that Bugatti a production car? |

I think the 1969 Corvette ZL1 has been documented at 520+hp. |

...but rated at 425. The specific documented case of one producing 523hp on an engine dyno (only two exist) was after the engine had been blown up, rebuilt, lost, found, and rebuilt again. All correct parts were used, but by this point the engine would have been effectively "blueprinted." The L88 can be considered functionally identical to the ZL1, though (it just had an iron block), and there are more-original examples of the L88 that have run just as hard. The L88 also preceded the ZL1 by a year. |

Also, I'd consider a car where only two examples were ever really produced something other than a production car. The term production sort of means it was replicated over and over, and the ZL1 just wasn't. |

i saw an episode of american muscle car on speed where they dynoed old school muscle car motors. they did the 409, cobra jet 429 and a few others, but they did the hemi 427 and it dynoed at nearly double it's claimed hp ![]() |

I wonder how much of this increase may be owing to increased gasoline quality over the past 30-40 years. I'm sure this must have SOMETHING to do with it, but I don't know how much. |
