agree with you on that one! lol

would love to know more about it though.

[The Black Flash]

It belongs to Gary who's the engineering bod at Dax. Dunno any more than that though...

heres a link to it on start up!!!! http://www.youtube.com/watch?v=xSRx0M2XTx4

But has he actually driven it?

[antnicuk]

thats almost as mad as his motorbike!

does it drive a gearbox or does it use thrust to make it move?

i always wondered how they get those huge jet powered tractor pulling things in scandanavian countries to drive the wheels.

CVT from the shaft?

What does a Jet ranger turbine make? 1000shp? Feckin horrible power curve too if it's not on a CVT!

[The Black Flash]

Be a gearbox I should think - gas turbine engines drive gearboxes, rather than producing thrust - this is how the donor (helicoptor!) worked.

The answer to the second is the same reason the Veyron got built i.e. "because I can"

any idea on how the gearbox of a helicopter works? wonder if they are CVT or fixed gearing. just thinking that its more about the torque the engines put out than the rpm as the baldes change pitch to torque the engines. thinking that a CVT would enable the engines RPM (and thus torque/power) to fluctuate but the rotor RPM to remain the same.......just guessing.

'fraid I don't know...but a post in the engineering/aircraft forum (whatever it's called) will probably get an answer

ok mate i will do.!

[ahdguy]

(Basically in simplistic terms, they have a rotor on a shaft in the exhaust flow and take the power off that (via a reduction gearbox))

There is a another video linked off that youtube one that shows some more pics of the car, and you can see the propshaft running down the tunnel through some kind of transfer box....

[SkinnyBoy]

thats mad!

Everything should have that sound on start up!

i found this through the links off that video

1985 Toyota GTV concept with gas turbine engine

Rover, of all people, made a couple back in the 50s:

0-60 in 14 seconds and 7mpg? Ouch!

[Lefty Guns]

Isn't there a GT-powered bike kicking about? Not sure if it made production but IIRC it was a 250kg, 400shp thing with 3 gears.

[anonymous-user]

Yep, Jay Leno has one of the gas turbine bikes

I remember years ago in Hot Rod magazine there was a hot rod roadster with the same engine, afair it had two gearboxes one behind the other
