Re: How Will Electric Vehicles Be Modified in the Future?

The allowable design stress in an electric vehicle is such that it should be able to handle something like a ludicrous made out of the factory. This is the crux of the disagreement and I'm sorry but you're wrong. Coping with the stress of ludicrous mode will have been baked into the fundamental des...

Re: Go Cedric!

There are more rules and inspection than there used to be but the law on vehicle modification in the UK is pretty liberal thanks to a long history of kit cars.

Re: How Will Electric Vehicles Be Modified in the Future?

The ludicrious mode just puts more power to the traction motors, which allows more power to the drive motor. Obviously this means more torque on the components but it's still within the allowable design. What's the distinction between the traction motors and the drive motors? Err, yes? I'm sure you...

No, it really, really wouldn't. It doesn't matter if needs to fold space and time, if the option existed at the press of a button they would still be around. This is hypothetical.

Re: Effect of holes in aluminum rigid fork?

The front and rear faces of the fork legs would be the areas under greatest stress so having the hole in the side like you have shouldn't be too bad.

Someone like Chalo with better knowledge of bicycle engineering may be better placed to comment.

Re: Effect of holes in aluminum rigid fork?

The motor does put a torque on the drop outs, but like braking (but opposite) it does try to rotate the entire bike around the axle, which flexes the whole fork. Aluminium is prone to fatigue cracking and put any holes in a fork that weren't designed to be there would be unwise. In your case, assumi...

Re: Oil cooling your hub- NOT snake oil!

The biggest drawback of oil-cooling for most people is keeping the blasted stuff where you want it - inside the motor. It can be surprising the number of places warm oil can find to escape: it will travel along inside stranded wire. While the ferrofluid seems expensive for a small amount of oil, it ...

Technology doesn't automatically always trend towards ever-greater speed/power/performance. But that's exactly what I said. It's probably going to tend towards efficiency.

No they're going to be better. If you're building off the premise that technology is going to go backwards in the future you may want to rethink this. It's never happened in history. It certainly has. 50 years ago if you could fly on a commercial aeroplane at Mach 2. Fast forward to the futuristic ...

I know the reason I'm not driving a Chiron is trunk space. :mrgreen: No, it's because even if you were given the car for free you couldn't afford to run it. Performance costs.

#1 best selling vehicle in the US - Ford F-series pickup And the Raptor is the flagship $70K 450hp model. Because that's what everyone wants, a "tuned" F-150.

Re: How Will Electric Vehicles Be Modified in the Future?

Of course someone could "improve" the software settings on a tesla to get more power. But the tesla engineers are unlikely to be surprised and impressed and wouldn't immediately push it as an OTA update because it would almost certainly unacceptably compromise some other parameter. ICE power is not ...

Sure but like I was sayin, the longevity curve is really based on stop/starts not top speed. I only way I can think you would need to do these mods would be if you were going to do an endurance race. If you ran a Cannonball and wanted to run flat out for a long time I guess it might make sense. Eve...

Re: How Will Electric Vehicles Be Modified in the Future?

Of course it makes sense. My first car (a Leaf) did just that. It limited motor output to protect the battery from overcurrent. I would say just because they did it doesn't mean it makes sense. I would put forth that the engineers only had the one motor to work with and it's a work around. Tuning n...

We dont know the exact order of events yet As i said... some of the detail timings are not known PUBLICLY. Particularly the exact time of the Hornsea shut down.

Hmm ...as i expected, your bias shines through again. 1)..The blackout was a grid system protection shutdown resulting from a major frequency drop . 2)...That frequency drop was caused by the sudden loss of 850+MW of generation 3) ..the Hornsea offshore windfarm was operating near maximum capacity ...

To put it another way, you've had a month and still haven't worked that out? :D
