2:17 Launch

7:03 Outro, and more revs

Recently added some HKS high cams and a skimmed and ported head that raises the compression ratio of the B6ZE(RS) to 10.5:1. The sound and tone of the engine has changed significantly and the top end is great, I've dialled in the fueling and was able to increase the ignition timing to great effect. The audio is taken from just the Zoom H4 mic as seen on the dash.
