Beating a world record is cool. Beating your own world record? That's arguably cooler. Hennessey Performance Engineering claims to have done just that, taking the monstrous Lotus Exige-based Venom GT to an even more insane top speed. We'll get the specifics on Monday; for now, there's a teaser video above.

To recap, a Venom GT making 1,244 horsepower from its twin-turbo 7.0-liter LS7 V8 hit 270.49 miles per hour back in February 2014, setting what Hennessey claims is the top-speed record for a production car (video below). We say "claims" because the definition of "production" is nebulous at best, and Hennessey only ran the car in one direction instead of running it both ways and taking the average, which accounts for wind and any elevation change. (Also, the record isn't recognized by any sanctioning body or Guinness.) That attempt was made at Kennedy Space Center in Florida – yes, getting the Venom GT to its top speed requires a runway made for the space shuttle. Before that run, Hennessey's rocket set a record at 265.7, besting the 1,200-horsepower Bugatti Veyron, but ran out of room, necessitating the change in venue.

This time around, the car has more power. This top-speed car is the new, 1,451-hp Venom GT that was originally shown at last year's SEMA show. To get the extra grunt, Hennessey boosted the twin-turbo V8 from 19 to 26 psi and tweaked it to run on E85 ethanol. Where will that put its top speed? You'll have to check back on Monday.
