My Dad runs a race team and prepares F1 cars for private clients. Today we got the amazing opportunity to see a 2000 Benetton up close, as well as have the amazing engineering explained by Big Kev! We shows the secrets behind the how F1 suspension is so light, how the gearbox is used to mount the suspension and why the exhausts are so curly!

From personal experience on 1994 Tyrrells and 1998 Benettons - their engines are Judd 3.5 liter V10s for sports cars and detuned somewhat. If memory serves me, 11,000 RPM vs 19,000 so they can run about 1600 race miles between a $45,000 rebuild by Judd. That still was good for about 750 HP in a 1400 lb. car. The cars I worked on used steel suspension parts instead of carbon fiber and used, not new, brake pads and rotors. On these cars the clutch was actuated by a pedal and the gearbox was shifted electrically. I think they had to replace all the wiring in the car to fit the new engine computer and data system. Racing historic F1 cars is not a cheap hobby, by any means.

The exhaust headers are the same length - you keep saying that “if they were the same length”. I’m not sure you’re grasping how this works, it has to do with optimizing the pressure wave through the exhaust to maximize efficiency of each cylinder removing their exhaust gasses.

I agree, I don't think he grasped that at all.. the header nearest the collector has the most contorted path because it has to be the same length as the furthest header from the collector... its not a new concept by any means, performance manifolds have been designed this way for at least 70 years that I know of...

On a tuned exhaust system, the length of the tube from the cylinder head to the exhaust header are all the same length, regardless of which cylinder they are. That length would be determined by the requirements of the engine....a high-revving engine would have a shorter primary pipe, and a lower-revving but high-torque engine uses a longer pipe. Your end requirements will determine the eventual length. This "length" could be measured by linear length or volumetric capacity.

As others have said, a coil spring is a torsion bar that has been curled up. If you looked at a slice of a coil spring and observed it springing, it would be doing torsion bar moves. I think coils are cheaper to make. No precision machined spline on each end. Just roughly wound in a spiral. I seem to recall that the stiffness of a coil spring rises as the sixth power of the wire diameter. Doubling the wire diameter makes the spring 64 times stiffer.

This was really cool to have some technical insight into an F1 car. I know for sure how important the exhaust is. I compete in the cheapest rally class here in Sweden which are running stock engines. The exhaust is free after the manifold though so me and my father built a new exhaust that was designed by my fathers friend. We ended up gaining 8-9 hp just from that exhaust and that is on a 115hp Corolla. In total with a new exhaust with race cat, sport air filter with attempts to make as much air as possible flow to the filter, remapping the control box and top decking and balancing the engine we are almost up to 150 hp!

Pretty interesting. I think you said that the exhausts were all different length. They are the same length and the convolutions are there because they have to be the same length. Also, there is more to it than just gas flow restriction. There are shock waves that travel through the exhaust gas (like sound waves through air) and those shock waves have a positive and negative pressure aspect. The trick is to get a negative pressure wave front reflected back from the collector to the exhaust valve as it opens to help suck the gasses out. A huge amount of power is gained this way. (but only at a particular rev range). Similar waves are used on the inlet side as well. A positive pressure wave can actually help keep gasses in the cylinder before the valves have fully closed. Pipe lengths and valve timing go hand in hand. Also, on the springs. The thing about the rear coil overs is that they coil over 'dampers' so it wasn't a fair comparison. Where were the dampers for the front suspension? Presumably they would still be a piston through oil, like the rear ones so they would take up space too. Also, a coil spring is actually a torsion spring too. It is just wound in a coil. It is still a twisting motion on the actual spring material.

How does that work when the ends of a coil spring are free to rotate around their axis?
@Igbon5
@Igbon5 3 жыл бұрын
@@phamnuwen9442 Good observation. Still it is a twisting motion on the spring that is the primary spring force if you think about it. Each turn of the coil actual prevents the the ends being free as you say. Just as if you bend the ends of a torsion bar 90 degrees to stop it twisting, the coil provides that function over the length of the spring wire. The alternate to it being torsion forces are bending forces like big flat leaf springs and while there may be a bit of that it is primarily a twisting motion providing the spring. So, it is the coil itself that prevents the rotation around the axis. Although I wouldn't be surprised if there was a tiny residual twist at the ends.

@@Igbon5 While I'm sure there is some twisting motion going on in a coil spring, I don't think that means it makes sense to call it a torsion spring. The way the suspension utilizes the different spring types is clearly quite different. Coil springs work by being compressed and torsion springs are twisted.

@@Igbon5 I think you're not seeing the forest for the trees here. A coil spring is used in compression by the system it's mounted in regardless if there is some twisting motion is happening inside the spring itself. A coil spring inside a compressive suspension could be replaced by a solid block of rubber or an air cylinder. You could not replace any of these things with a torsion spring unless you changed the suspension system to one that uses torsion.

Straight torsion bars have existed since the earlier days of the motorcar. The ones featured here are advanced-material versions of a classic design. I wish they would have covered the rebound dampening process inside the nose of this modern marvel. The old-school dampener versions had stacked adjustable disc pads with a tightening screw in the centre to adjust the friction, thus speed, of the rebound. It actually worked well for it's era.

Technically, the torsion bar is a spring. It is not in the sense of how a spring commonly looks like. The torsion bar deforms elastically and when the workload doesn't exceed the yielding stress of the torsion bar, the bar springs back to the original shape. This is fundamentally how things (any springs) deform.

And many Peugeots! And Alfa’s... Loads of great handling light cars in general. I think the main reason they’ve fallen out of favour is due to the increased weight of newer cars, even on light old cars like 205 they’d settle and need the height adjusting over time. Also if they break while a cars under warranty, it’s a lot harder to extract than a broken coil spring on a strut or a rear beam.

Nope. The coils don't twist, they're flexed sideways at any point along the coil, as the whole is compressed. Any rotation observed is due to the sideways movement being expressed along the coil, it's an optical thing, not the actual moment of change.
