I'm surprised the parts need up on the floor, I didn't really hear a bang which I thought there would be if it went. I'd imagine just doing donuts adds alot if heat to the engine which if actually moving would be forced out.
Yeah, they run hot enough even when not being pressed, and with plenty of air flow.Front bottom said:
Doughnuts and burnouts etc. are for kids. Who knows how many times the driver in the vid has done this to the car in the past whilst showing off to his homies?
It could have been low on oil, it doesn't seem very well cared for after all.

Hamilton
Air Vattenan
Tiff Needle
M Schumacher

Etc etc
Must be the cery expensive to attend Festival of speed is a kids event.
Actually all those car shows and Russ Swifts whole career is just for kids.

On the burnout/doughnut subject though, It's a bit cringeworthy to me, always has been. I appreciate what you're saying with the above examples, but it's really not for me.
I remember seeing some numpty doing a burnout in an e28 5 series years ago, when I was about 18. I should have been the perfect target audience at that age, but all I thought was 'What was the point of that?'.

Bmw m cars should be able to ... sit on the limiter!
No. That's not what the rev limiter is for. It's there to prevent momentarily overspeeding the engine as you accelerate through the gears, not for some sort of near continual use. The rev limiter cuts fuel and/or spark to keep the engine speed down. This is not exactly great for the engine but far less harmful than overspeeding it.And odds are this engine has been chipped, perhaps even raising the rev limit. Not a recipe for engine longevity.

The point is to bring in heat into the tyres to aid grip. Also it’s a traditional method to celebrate a win or its as part of a display (some like synchronised swimming others like cars being used in stunts)On the burnout/doughnut subject though, It's a bit cringeworthy to me, always has been.

Personally I have never done it in my car - and when I have t was in a Caterham where you had to do that as part of the circuit.
You cannot enjoy Drag racing

Not a fan of drag racing tbh. My favourite kind of racing happens at Goodwood these days - 60s Saloon car racing. The classic Mini Cooper S' on the absolute limit doing battle with Mk2 Jags and Ford Falcons etc.Personally I have never done it in my car - and when I have t was in a Caterham where you had to do that as part of the circuit.

Not a doughnut in sight (I'll probably be proved wrong now).
e with no mechanical sympathy.Saw this the other day, what a monumental spanner, what did he expect was going to happen?
Have done a lot of research into the V8 and V10, bearing failures have happened to both engines but nowhere near as many as the internet would have you believe.
Some have failed sub 50k, some have lasted over 100k seems to be luck of the draw! Worth factoring it in when buying a used one now if it hasn't been done. A rebuild is extortion if bearings go south.

You must think all drives at the Festival of speed are real idiots too then?
Doughnuts and burnouts etc. are for kids.Before you start quoting Hamilton ect, they don't pay for tyres or engines and could care less when they give out, money talks.You must think all drives at the Festival of speed are real idiots too then?
I personally i don't see any point in stressing your pride and joy like that.

The poor engine, the poor transmission. It's just so idiotic.
Ex owner here but the rod bearing thing does my nut in. So much BS in this thread.
How is it there are some US cars with 200K+ on original bearings??
This guy swapped out at 65k and guess what...

Failure rate supposedly 1%, ment to be down to abuse of the car as in the OP's link particularly from cold.
They don't just melt away like a piece of chocolate. Just dick heads come online and moan because their car's engine shat itself through no fault of their own, just that the rod bearings disintegrated in thin air. Was nothing to do with the cold engine abuse or the fact they went to tesco car park and did donuts for 30 mins straight.
