Yeah, 30s/40s vs 60s is a huge difference. That being said, the bones aren't the troublesome part, it's that your brain gets sloshed around inside your skull and turned into mush without proper crumple zones, restraints, and airbags. That is, if the non collapsible steering column doesn't impale you through the chest. The numbers that get thrown around at work when discussing impact safety are insane. We're talking 10, 20, 30 Gs impact force. There are even standards for safety if the owner is one of those "but it's better to be thrown clear of the accident!!!1  " types, certain fairly significant crash tests need to be passed even without a seatbelt in use. I don't know why we don't just let darwin take care of those idiots, but hey, lawyers.

I wonder what trickery they would've had to perform with the suspension geometry. All the angles would be significantly different at that speed, with the suspension compressed from downforce, than they would be on slower corners. They would have to juggle between it being sluggish at low speed vs prone to railroading and bump steer at high speeds.

So at slow speed the car sits high and is too stiff and doesn't handle well. To sort of get around the problem, most high-downforce cars have gone to a 3rd spring setup where there is an additional spring (and sometimes damper too) that only acts when both wheels are compressed. So going around a corner, one side compresses, one side extends, and the 3rd spring does hardly anything.  Some friends of mine are having the opposite problem and have to re-design the suspension before it will go any faster, no matter how much power and wing they throw at it. jamal fucked around with this message at 05:47 on Jan 6, 2014 |

It's like the opposite of an anti-roll bar.

I visited the Petersen museum here in LA on the last day of 2013, here are a few things I took photos of. We also took a tour of the underground vault they keep cars not on show in (you can't take photos down there), it's amazing. So "The Petersen" belongs in this thread in spirit.

There's a Senna film (The Right To Win) that includes a segment where other drivers talked about the micro-adjustments that drivers do on the fly with the controls on their steering wheels. Going into a corner, you drop the suspension or something, and things like that. He cited it as an example of why Senna was so good: he could make these adjustments faster and more accurately than other drivers. https://www.youtube.com/watch?v=ShPc3nY5m5w&t=1063s anonumos fucked around with this message at 17:37 on Jan 6, 2014 |

What always amazed me about the 1980's era LeMans cars was how drat fast they were. Best example is that the Porsche 962 STILL holds the Nurburgring lap record to this day with a time of 6:37. His qualifying time was 6:11  That was done in 1983 by Derek Bell:https://www.youtube.com/watch?v=G0z9TbFW6tU Look at the "Competition" list of times: http://en.wikipedia.org/wiki/List_of_N%C3%BCrburgring_Nordschleife_lap_times Best part of the YouTubes is all the narrating  Those Porsches were, and still are, something else.

And part of the reason those laptimes have never been beaten is those were the last years that full-fat prototypes raced the nordschleife. Now the fastest thing that goes round there under official timing and scoring are GT3 cars. If the full course was a round of the WEC you can bet that 30 years of advances in drivability, tyres, aero, and the like would mean we'd have a sub-6 second lap by now.

It's also where most of the magic of a good race engineer comes into play, especially since a lot of them are no longer standard shock absorbers - you're seeing, depending on who you ask and when, "J-Dampers" or "inerters". Read this if you want to go cross-eyed.

Yeah, Uwe Alzen ran 8:02 for the new + old track in a VLN BMW Z4 GT3. That would correspond to a 6:22 lap of full Nordscleife and a 5:58 touristenfahrten BTG (Bridge-To-Gantry)lap. At Spa LMP1 cars are some 20 s faster than fastest GTs. Extrapolating from Spa, a LMP1 prototype might be able to run a 5:20 full lap on Norschleife or a 5:00 BTG lap... That's quite fast.  Of course it is a quite an assumption that the extrapolated laptimes would match reality.
