Hennessey Venom F5

Saw this yesterday, I'm having a hard time believing that car can reach that speed.

If I see an electric wheelchair doing a burnout and doing a 15 sec quarter mile I'll take a picture of the Hennessey name badge!

And they said pushrods were outdated

290+ MPH seems very possible because the Venom GT was still pulling hard at 270 MPH. They just need more room. Maybe the Bonneville Salt Flats would be a good place.

I don't. Top speed is essentially a function of cross sectional area, drag coefficient, and power. And enough space to achieve that speed.

A car with a frontal area of 22 square feet, a drag co-efficient of .31, and 1400 hp should be able to hit 290 mph. Those are all very achievable figures. And if they managed to beat them, even just by a bit (say 21, 0.30, and 1450), it gets substantially easier to hit 290 in a given space (such as a very long runway)

There are advantages and disadvantages to Bonneville. A car will go faster on pavement than it will ever go at Bonneville, too much rolling resistance from the tires digging into the ground. And as flat as it is, its still a fairly rough surface. Cars that are built to hit land speed records on salt flats can reduce the impact of these things, and many have no choice as it takes so incredibly long for them to get up to speed. But regular street cars can only do so much. Eventually, you can reach a point where there is no accessible (I hear there are some super long runways on USAF bases in the deserts of the south-west) stretch of pavement long enough to reach a car's aerodynamic top speed. At that point, a place like Bonneville is the only option.

These guys are doing amazing things.

That's pretty sweet. Looks better than the original Venom as well.

add wings + flaps = carplane
