Does look much more like the spread from a thin oil.
Petrol would go up much faster, see Grosjean's crash.
the bit that was blowing up before flames engulfed the bodywork was from the front area of the sidepod to the lower rear. Before the blow up, the exhaust can be seen shooting out debris.poz wrote: ↑13 Jul 2022, 18:41turbos can explode. imagine something at 15000 rpm suddenly stopping because a piece of an exhaust valve goes inside it

also the most damaged part is at the rear of the engine, where the turbo (splited or not) is
of course it'all assumptions
I suppose this is not the first time we’ve heard this, but encouraging if they still have this kind of upgrade to come - could be a significant upgrade at these types of tracks.
Perhaps. It is a tad too smokey.dialtone wrote: ↑14 Jul 2022, 19:16I'll repeat that it's very unlikely it's petrol, there's way too much energy in burning petrol, if there was a leak it would have been a lot faster than that, and more violent.
It's more likely it's oil from the turbo, when the turbo broke and exploded, oil started leaking out and the heat ignited it.
Wasn't violent enough?dialtone wrote: ↑14 Jul 2022, 19:16I'll repeat that it's very unlikely it's petrol, there's way too much energy in burning petrol, if there was a leak it would have been a lot faster than that, and more violent.

It wasn't violent at all, that little explosion is par of the course when you stop a spinning turbo.PlatinumZealot wrote: ↑17 Jul 2022, 15:48Wasn't violent enough?dialtone wrote: ↑14 Jul 2022, 19:16I'll repeat that it's very unlikely it's petrol, there's way too much energy in burning petrol, if there was a leak it would have been a lot faster than that, and more violent.

It's petrol alright, the initial explosion.
The flames afterward could be other stuff, but I doubt it's oil because it was burning pretty clean and oil doesn't burn clean.
Thin, hot oil burns pretty quickly and cleanly indeed. That's the basis of most home/workshop oil heaters after all.PlatinumZealot wrote: ↑17 Jul 2022, 15:48

You may be right about the cause, but that's not a representative counter example. Fuel was splashed around in free air where it could vaporise.
More like 150k rpm…..poz wrote: ↑13 Jul 2022, 18:41turbos can explode. imagine something at 15000 rpm suddenly stopping because a piece of an exhaust valve goes inside it

What are the regs like in this area? could the entire inlet be that height?Xyz22 wrote: ↑21 Jul 2022, 13:47
"Significant upgrade of venturi inlet design now double profile. Increased downforce via more volume in the undercut. Evolved floor."
