5 valve per cylinder all the way to their vee twelve engines. notice how narrow the cam lobes are with that desmo, goes to show how little load is needed to open valve if there was no valve spring. since the combination of both opening and closing would come to the same width as a normal sprung valve, this would might mean it doesnt take much to open and close at those rp/m. however, being ferrari, maybe the lobes are narrow simply from them using some sort of high strength material to achieve thate36jon wrote: ↑03 Jul 2018, 18:31Wow, 3 cam desmo on a Norton?!? I had no idea they went there... Fancy race solution or was this a production item?
Edit: The unit shown was a proto and the article I saw said it never raced... Cool though. Good link here for more info: https://www.desmodromology.nl/norton-500-single/
Since we are getting our desmo on, I submit the 1989 Ferrari 034/5 3.5L V12 F1 mill. 13,000rpm and 660hp. And desmo, at least in proto form. I'm having a hard time nailing down what's what...

Does that thing have some kind of CVT? The last chassis dyno graph looked like a constant power curve. I don't speak French so maybe it was constant tractive effort which would make it a slipper/centrifugal clutch not a CVT.J.A.W. wrote: ↑11 Jul 2018, 06:48Well.. there are toys.. then there are.. 50cc/20hp toys..

Great observations Powerslide.5 valve per cylinder all the way to their vee twelve engines. notice how narrow the cam lobes are with that desmo, goes to show how little load is needed to open valve if there was no valve spring. since the combination of both opening and closing would come to the same width as a normal sprung valve, this would might mean it doesnt take much to open and close at those rp/m. however, being Ferrari, maybe the lobes are narrow simply from them using some sort of high strength material to achieve that
whats also is interesting is if the returning rocker arm is not made to stop the valve lift any further or its lift dead center. this would relieve a lot of energy away from the rocker and stress is only to close the valve
What on Earth are those tires doing on that beastly looking car.
Is that some sort of battery with a gas generator on top? Anymore information about it?
Its an electric car with gas turbine powered generator.graham.reeds wrote: ↑20 Jul 2018, 13:25Is that some sort of battery with a gas generator on top? Anymore information about it?
Clearly not been running as the engineering has a bare hand on the exhaust.
And surely the range is dependent on the size of the fuel tank?
