Seems David Piper is suing Mark Hales for blowing the engine on his 917...

http://www.telegraph.co.uk/motoring/news/9808987/Y...

... is there more to this than meets the eye?

I would guess only one person knows what really happened - the guy behind the wheel.

Surely Mr. Hales can simply pay a comparatively small fee to have the condition of the gearbox assessed, proving that it was the cause of the over-revv? (assuming it was, but in actual fact probably wasn't)

How did they know it revved to 8200rpm? Does a car that old have an ECM?

917 rev counter will have a tell-tale needle:

Tell-tale needle on the tacho probably

If an engine blows, does can it over-rev as it lets go? (I have no idea)

Not without an increase in throttle or a clumsy downshift over-speeding the engine through the drivetrain. A gearbox issue, however (missed gear, jumped out of gear etc) would suddenly unload the engine and it would rapidly speed up even if the throttle position remained constant.

What a pair of clowns! Spending money on lawyers will only increase the cost dramatically. It's a classic case that they should pay half each just to get rid of the thing. But I guess no-one's keen to shell out £20k for a short day out.

However, the real question is whether Piper can prove a full "you bend it, you mend it" agreement and that the £2,000 deposit wasn't the maximum recoverable.

yes

We've had a clutch pack failure in a lenco lead to a massive over rev as the loaded engine is the free to spin.

Imagine working hard to undo a bolt with a spanner, then it suddenly lets go.. That energy has to go somewhere!

"You bend it, you mend it" - seems perfectly fair to me, it's a famously expensive racing car, if Hales had any concerns about not being able to afford it going 'pop' then perhaps he shouldn't have driven it.

Whenever I see the tell tale needle i think of Days of Thunder.

You'd think that the journalist would have insurance to cover this kind of thing?

Accident damage, yes.. Mechanical failure, unlikely..

I imagine insurance would cover a crash but not mechanical failure.
Tankslider Friday 18th January 2013    
There is more to this. He wasn't driving it for giggles, and he is about as well qualified to drive something like that as a journalist comes.

Very sad that it has ended up in court.
RicksAlfas Friday 18th January 2013    
It's a shame as both guys (in my eyes) seem very respectable gents who I imagine know each other well and should be able to sit down and talk about it.

As an aside what happens in historic racing where it's often a guest driver racing (and pranging) someone else's very expensive car?

Aha! Thanks!

That's exactly the scenario 'bend it, mend it' was invented for. Certainly I wouldn't consider lending my car to anyone who couldn't afford to either insure it or fix it, and I would never consider lending a car to anyone with whom I'd need more than a 'gentleman's agreement' with. Mine is only a cheap car but the logic still applies.

ETA: It's always a little more complicated around mechanical failure though, because the argument will always exist- was the part 'due' a failure, was the car ill-prepared? Or was the failure caused by careless driving? As Ozzy Osmond said, you'd hope that in this instance they could reach a compromise, based on when the engine was last rebuilt- at the end of the day, it's a highly tuned competition engine and it has a finite life between rebuilds, there is a risk every time it is run.

I wouldnt describe Mark Hales as a 'journalist'. He is an extremely experienced racer who now writes too.
