[Angel And The Wolf]

And here's a neat thing about joining the two at an intermediate shaft with chains. If I synchronize the second engine 45 degrees apart (instead of 90 degrees apart) from each other, the sound will be like a Harley. (if that gets you off,) instead of a 90 degree V8.
Of course, with a redline of 8000 RPM, you will get a harley sound like a single harley engine at 3 times the redline, (16,000 vs 5,400)
and with the engines 90 degrees apart, you will get a CB750 sound at twice redline (16,000 vs 8,000)
