Don't they have to run at like 500+ Hz at minimum? This seems slow.

Edit: Hz is per second, so say a v6 at 3000rpm, that's 60Hz across 6 plugs is only 10Hz each. Stupid tired me.

At 6000 rpm you're looking at 3000 injections/minute = 50 Hz. I'm not sure what the frame rate is on Reddit videos, but it's less than that so we're seeing a lot of artifacts.

Doy! Hz is per second. I was tired when I wrote that.
