Wow. So the mule loses out by .3l and a bit of compression. But has a spool valve, and for all intents and purposes, those are pretty similar sized turbos.
It'd be nice to see the mule building boost "normally" without surge. Still, the 07k is making so much more torque early on its insane.
Very cool to see how the different setups work. Only thing better would be same exact turbo.
