Thread: now this is gotta hurt, for sure

Wow, how to split a tractor in record time..

This is how to remove an engine in record time...

I like the bit where it says "Rob has done some work to the engine and he wants to see what it does"...

It actually splits the block and throws the whole top of the engine skywards... What sort of cylinder pressures do you think it was running just before the end...

I guess this shows why flywheel power as an alternate to electric vehicles has never really made it to the public. You'd risk this sort of thing each time you had a minor accident!

There have been trials of flywheel type systems in WA for baseload (fixed power).

Flywheel type drive systems would not have these sort of problems, because you are spinning them up slowly, rather than trying to accelerate them quickly as in the examples here.

There was a US cummins 6 which did the same, running 100 psi boost from memory.

Is this a petrol?

These definitely are petrol (and one kero)

It's no wonder that some of those engines let go... There's just MASSIVE amounts of torque going through those bottom ends.

I'd love to see an instantaneous pyro reading too

Great to hear about the trials in WA. Got any links? I'm teaching a unit on renewable energy systems next term.

I agree, for fixed systems, flywheels can be great. For mobile systems (like cars etc), you can get fairly instantaneous deceleration happening in accidents. If the flywheel could be contained under such circumstances, would surely be a better system of energy storage than batteries.

Rear engined 1/4 mile drag rails were developed after Dan Garlitts clutch/
flywheel came apart and took off part of his foot.
Back in the 70's, I think.

NASA is involved with that.
