Video: Hennessey Venom on the dyno - 933 hp at the wheels!

By now, we all know that Hennessey has a reputation for taking fast cars and bestowing upon them loads of horsepower. But now they are working on something quite ambitious for even an experienced tuner - building their own car from the ground up.

And an impressive car it is. We have seen pictures, video, and read lots of specs on the Venom GT, but until all the talk is backed up with some real dyno time, naturally everyone will have doubts. This video effectively silences them.

The final version of the GT features a twin turbo V8 sourced from the Corvette ZR1, and it churns out 933 rear wheel horsepower and 874 lb-ft of torque. And this is with regular old pump gas, no race fuel here. We are just guessing, but we don't think that a gross hp of over 1,000 is going to be a problem.

Hennessey Venom GT to debut at 2010 Geneva Motor Show

It's been two years since John Hennessey announced that he was going to be building his own supercar, but the plans are still a go as it has been announced that the car will make it's debut at the 2010 Geneva Motor Show.

Some specs have changed. Curb weight is down from 2700 to 2400 pounds. The proposed engine is now a "Hennessey V8" instead of a Viper V10. Power is up to 1200hp rather than the inital 1000hp, and top speed is said to be 274mph. Soon we will know if that car can pull off these lofty goals.
