I think the bigger you go on the turbo the easier it is to run more boost on a given octane. I think my 10:1 compression on 92 is a pretty good handicap and I still squeezed out 30psi spike dropping to 27. I wont say its exactly like 91, but its probably pretty close.
When you have a bigger, more free flowing turbo and other parts of your setup have been optimized for flow (bigger, ported, etc) then your knock threshold goes down and its easier to run higher boost on a given octane.
The 24psi you quote as max on 91 oct is basiaclly the stock turbo max.
Also check out razorlab/GST motorsports about testing bigger boost on 91oct. Dynos and info about running 27lbs w/ a FP Green on 91oct.

That's where I am at. I'm looking to buy cams, trying to get a good setup for track days and autox that I daily drive. This setup would be a road course monster, but exactly what is the magic here? I mean an FP Red spooling like a stock 9 turbo. Just staggering area under the curve.

I know this is old but I don't care. Is this powerband like this because its a 9? Because of the tuner or what? Cause 95% of the reds are not doing this on pump. I'm not calling job a liar at all. Just asking if this is seen often or was this just a monster car?
