009 - Exhaust Design
This will be news to exactly no one. But life has a way. A way of twisting itself into a complicated sticky mess. And that mess has a way of postponing, delaying, sidelining projects that don't fill a basic human need. No one needs to build one of these cars. So when life presents itself in difficult ways... the car will take a pause. We've been pausing, but are ready to hit play again.
Here's Jack and Lena prepping the engine on a stand for some of the next steps.
We mentioned that purchasing the engine was out of order and doesn't typically happen this early in the process. The reason? Exhaust. Or more specifically exhaust designed for a race car with no real considerations towards civility, decibel levels, comfort, and so on. Does it sound amazing? Yes. Does it still sound amazing after driving for an hour and your ears are bleeding? I don't need to answer that.
The stock setup is headers straight out the side of the car into side-pipes that really aren't muffled in any meaningful way. 100% race car. Many builders just deal with it and wear ear plugs or noise cancelling ear buds. We could do that, but I think there's a more elegant solution.
As designed the car doesn't sound like a true V8 because you're only hearing 4 cylinders on each side of the car. An X-Pipe or crossover balances and mellows that sound to achieve that tuned V8 rumble. In addition adding catalytic converters will make the car more compliant and further mellow the sound. Some would argue these modifications take away from the race car essence, but I would argue that if it's painful to drive it takes away from its purpose as a car.
All of this however is a packaging puzzle as the car was never designed for this sort of setup. But for me that's part of the fun. There's always a way to stuff 10 lbs. of hardware into a 5 lb. bag. Is it worth the time and money? Stay tuned as we figure that out.
Below is the basic layout of what we're trying to achieve. This is purely schematic and in no way takes into account the physical limitations or 3D nature of the puzzle.
If all of this seems like ridiculous nonsense you're not wrong. But! And this is a big "but". This nonsense is wonderfully amusing to me.
