How F1 Sound is made

Wait, is this clickbait? Yes, because I really want to tell you about the stricter the phone calls used that made them sound more special. There is a way to turn exhaust noise into something more like music and until today it has been somewhat of a secret. No, they are not dead. Just a moment, before we get started, I really want to show you this rubber horse. That looks so stupid, nobody's gonna click that. With the clickbait nonsense out of the way, let's get started. How a phone sound is made. Remember this? That was one of them, but it sounds probably not how you remembered it. I think this one sounds a lot more like what you had in mind. This is their phone sound, I mean. I figured out how they made that and I can also tell you when. Roughly, roughly between 97 and 98. From one year to the next, even the sound of the V10s was taken to another level. And that was exactly the change I was looking for. But I only came looking because I was trying to figure out the secret behind this 8x1 header that has the same kind of musical exhaust note. At first I thought this is the result you get from an 8x1 header. 8x1 headers are already a cheat code for crossplane V8s. They even out the exhaust pulses like you would get from a Ferrari. But this one is extra special. It has a built-in sequential firing sequence just like a revolver. Most people don't do that. But I did. No, we did. But not on a V8. No, a V12. And it sounds nothing like that. And I was so sure it would work this time. This time? Yeah. For nine years I've been trying to figure out the secret behind this musical exhaust sound. Back then I thought this was easy. But nine years later, nothing made sense anymore. Let me show you what I mean. Here are four equal length 8x1 headers. All with the sequential firing sequence. But only two get that musical exhaust sound. Can you tell which one? It's not these two. It's these two. But can you tell why? I couldn't. I've even called a fabricator of those. Why do your 8x1 headers sound so special? It's the sequential firing sequence. Most people don't do that. No, it's really only the ones he built. After nine years of reading up on engine design, music theory and lots of trial and error, I was completely stuck. I didn't even know what to look for anymore. And I didn't know who to ask. The people that figured it out don't talk about it. Why am I here tonight talking to you about engines? Well, the simple answer is because the engine guys never talk to anyone. In nine years, this was the first time I had nothing left to try. Until I remembered this one question the fabricator asked me over the phone. How many times did you- Suddenly, everything made sense. It was the last piece of the puzzle I was missing. To discover how a front sound is truly made. I've discovered a secret. What to do with secrets? If you find a secret, you face a choice. Do you tell anyone? Or do you keep it to yourself? It's rarely a good idea to tell everybody everything that you- It's these steps. Every time a pressure wave passes by these steps, it splits in two. It increases the amount of pressure waves to a number far beyond what usually comes out of the cylinders. And when these split-up pressure waves arrive at the collector, they get multiplied again. In addition, gradual changes in exhaust size like you find in collectors, X-pipes or cones will stretch out the spike of the pressure wave into something more like a sine wave. Like you find in a music instrument. Formula One teams started using stepped headers in 98. The two 8-in-1 headers used them too. The fabricator of those 8-in-1 headers learned his craft in the 70s. He knew about the power benefits of long tube stepped headers for ages before F1 engineers started using them. He always stepped them up, but in an uneven firing crossplane with regular headers, you won't get that musical sound. This can only be unlocked in combination with cheat code headers that space out the cylinder firing sequence evenly. Even the sound of the Formula One V12s is based on the same physics principle. But it's applied in a slightly different way. But let's be real. For over a decade now, the FIA has shown no intention to bring those screaming engines back. They just don't care. But I do. And I'm tired of waiting for the FIA to change their mind. But with the right knowledge, the tools available today, and passionate people all around the world, I think we can make that happen without them. But I can't do it without your support. Thank you. When you share your secret, the recipient becomes a fellow conspirator.
