big turbos mated to a big V8 like that it will make most of its torque midrange..unless Hennessey have a sequential system ..which I doubt..I'd say they slapped 2 massive turbos to either side of an LS..he was shifting at 6k which is where it would be running out of steam
Perhaps it would make most of its torque midrange, but that doesnt mean it wont make more Power at the top end, even if torque is tailing off.Megaflow said:
I'm impressed they can make that much power, that they only have to rev to just over 5000rpm, they can get from 70-215 in 10 seconds and can a water temperature of just 76 degrees.
This lot need to show the masses of VAG engineers who built the Veyron how it's done.
Or more likely, it's all total bull..................
The engineering achievement of the Veyron was to build a reliable car that any unskilled, rich, show off can do 200mph in. If you don't care so much about driver friendly handling and can tolerate more frequent drive-train rebuilds there are hundreds, if not thousands, of cars built in sheds that are faster than a Veyron.This lot need to show the masses of VAG engineers who built the Veyron how it's done.

I have no trouble believing Hennessey have built a car that can accelerate like that despite their occasionally flaky reputation. If you want to do it more than a couple of times or put in a fast lap without skill on par with Walter Röhrl it might be a different story.

Having said that, I'd be interested to see how tractable the Venom is and whether it's an on/off type power delivery - which I suspect it probably is.

I am thinking, unusable, undrivable, pointless. I will have a regular Exige please (because thats exactly what it is if were honest)
Where's your sense of adventure? .. It's like a Speed 12 or a Cerbera. Sensible man says Cerbera. I say speed 12. Just because too much is never enough. Fire99 said:

It may be an 'interesting' experience taking one around some damp oily UK roundabouts, with any conviction. It may sound like I'm being hyper critical of the Venom, I'm not. I absolutely love daft stuff like this, but I'm equally savvy enough to realise that it's probably going to be a bit of a pig to drive.
Still, I'm very glad there's still folk out there building mental stuff like this

Why would it be? It has over 6 litres spinning what are probably a pair of GT30s of some sort. ApexJimi said:
True, technically there's no reason why it shouldn't be tractable with such high capacity. Time will tell I suppose...
The capacity may be high compared to most cars, but it's still putting out around 200bhp/lire; it's not going to be short of torque at low revs, but it's still going to have a damned steep torque curve when those turbos come on song. I think the 725bhp supercharged one is probably a bit more... sensible.

70-200 in 10 seconds is "only" averaging 0.6g. Even assuming no down-force, I'm quite surprised it's traction limited at the point of the last gear change. I think mid engined RWD setups are usually good for about 0.7-0.8g of traction? It did look like he was struggling to put the power down though, which does beg serious questions of the setup.
Or have I calculated something wrong?
Maybe he's getting lots of aerodynamic lift at those speeds?Or have I calculated something wrong?

Well as for the 70-215 run I believe it was limited by the track they were probably on covering 0-215 would require a lot of land and of course they can't do it in public. I am pretty sure this is the worlds fastest and quickest car now. I also think hennessey has a very good reputation and a pretty extensive hostory of making the already great cars simply amazing. If you get a chance google some of his vipers.
