Other made an engine-sound simulator that doesn't take much CPU, here's what the porsche mission s might sound like
the simulation is quite simplistic rather than a full-on physics-backed sim like angethegreat's one. this does mean it's cheap to run CPU-wise, this one's running in the browser. which means something like this could be used in sim engines.
lots of engine layouts are possible and sound (to my ears) fairly good, including rotaries! no 2-stroke engines yet. I'm also not quite happy with how the burbles/pops sound.
turbo stustustustu is there in some of the cars, as well as straight-cut gear whine, and supercharger whine in the r53 mini. I'll record some more clips demo-ing these.
the cool thing is plugging in configs from real engine parameters, and having the result sound pretty close to reality with a bit of parameter twiddling. the v10 for example has that major-3rd harmonic interval that sounds so cool.
I went a bit overboard and had too much fun with the doppler flyby feature, and a 'tunnel' toggle. and the silly engine animations.
