What is the sound of one piston slapping?
What is the sound of one piston slapping?

I was coming up with a balancing idea for my flat twin concept. I was wondering if there was a way to use the crankshaft to balance the rocking at higher rpms. I also had an idea of using the exhaust pressure to push a counter weight that balances out the rocking. The exhaust would still be directed to the turbo right afterwards. The intake pressure would push the cylinder back to the exhaust side of the counter weight.

I was also wondering if unequal header lengths (like subaru had there turbo EA engines) effected the boost transfer to each cylinder (It would effect the intake lenghts too right?).
