      I LOVE the segment about the exhaust system!! I credit my late Dad for my interest in motorsport and classical music, though I never had the capacity to do anything with either. SO, when I was very young (1981-ish) watching some motorsporting this or that on T.V. with him, I saw the "bowl of spaghetti" pipes on the engine. I had been under the hood of the ol' '63 Chevy handing him wrenches a lot already and knew they were exhaust pipes, but Dad's manifold didn't look like that. I asked why they look so weird and he muted the T.V., took me outside and popped the hood and explained so that my 6 year old brain could grasp the basic why of it and why his was different, etc. What he didn't do is the typical dad reply: "Cause it works better, shut up or go play outside." The video did clarify some more like engine tuning that I never really got.

    The five-in-one header work like a Bernouilli pump so that the flow from one cylinder will create low pressure in all the other cylinder tubes to suck out the exhaust when the valve opens.

    I run a 1950 car as a fun vehicle (Jowett Javelin). If you remove the rear seat cush, you can see the torsion bars running the width of the car. Interesting to see how much shorter they are now, even allowing for the difference between road and race cars. Some dishonest bird-cage gentleman once put my dad off keeping a Wolseley 6/80; said the torsion suspension was "about to collapse". Wanted to sell him another car.

    Fascinating. Torsion spring at the front suspension is quite interesting since it reduces weight, cost, and packaging difficulty. But, how does the front suspension dampen the forces? I'd imagine there needs to be some dampening mechanism to prevent the front of the car from oscillating continuously. Would the damping due to tires and other components suffice?

    So, coil springs were replaced by torsion bars. If the 2000 Benetton's front suspension already used torsion bars, then I assume the 2009 Brawn's had torsion bars on the rear's suspension. Although, anti roll bars could still use coil spring. I think. So, no mystery if that suspension collapses.

    At 4:25 the son says, "If they were the same lengths they wouldn't come out, they'd all bang together." Wrong! They are all the same lengths. The pistons fire at different times and the exhaust pulses travel the same distances to arrive at the collector at different times. The pulses don't bang together. The pipes that start closer to the collector need to be curved to be the same length as from the farthest cylinder.

    The wire in a coil spring twists EXACTLY the same as a torsion bar. Same principle, but merely wound into a coil to fit the design. This is why there are hard rubber/plastic SEATS at each end of a coil spring - it preventthje coil TWIST wearing out the metal in the arms, etc. Don't believe? Get a small coil spring and clamp the wire on one end. Now, compress it, watch the wire TWIST.

    So I'm still confused about the exhaust lengths. It sounded to me like your father was saying that the pipes prior to the collector needed to be the exact same length, which made sense to me since each cylinder (on one side of the bank, obviously) fires at a different time and thus the gases from that explosion would reach the collector at a different time. Meanwhile, you're saying that they're all different lengths in order to ensure that the exhaust from any given detonation reaches the collector at a unique point in time. Which way is it?
