93 Octane warm-weather FATS, as I commute to work last week ;)
I still haven't installed my new intake manifold and phenolic spacers, IC water cooling and a bunch of other little things... of course my cats are installed and my car was full of lots of stuff. It's a daily driver 
It's a bit off 94 octane FATS but practically the same. FWIW, my K16 would normally be pulling ~4.0's in similar conditions.

Thanks MarkP for the smooth EcuX-friendly fatscalc

16<24?
I did a few comparison posts. But the main thing is that it spools slightly quicker and flows more at every RPM point.
When K16 level off at 6600 or so the K24 increase right to the limiter. Because of this, I'm convinced I can crank it up more, but 24.5psi at redline somehow seems sufficient to me.

Yep, by quite a bit...

Larger inducer and clearancing nets 300rpm or so
This graph doesn't fully illustrate it, but you can see how the low end flow diverges.

85 too :) 95, nice octane!
I still have to do some "real" FATS runs and use some of that 100oct nectar around here. It should be pretty brutal.
Those stock IC's recover pretty quickly at speed. Honestly, on the FATS front I couldn't prove data-wise that the upgraded ones helped me on K04.16. On the 1320 they were worth a solid .2 though

) Oh, and nice results too ;-)
