Thanks for this, this is super useful and tbh quite exciting, especially as that's the smaller housing again. It says Pump in the dyno run at the bottom, was that a pump gas run? And are you sure that's the 0.49? If it is, amazing.

I won't be using E85, I'll be using UK 98 RON fuel. I am trying to find what that means in the USA on google, looks like the comparison would be 90 MON or 94 PON, does that make sense?

I haven't been told I need to go bigger, I appreciate how well the compressor flow on these G series turbos.

I had a twin scroll EFR7670 on my last SR20DET and it was just awfully mismatched to me, so I'm looking for a much punchier car.
