We both know the values, hell I even provided the knowledge for a 800+rwhp 12A! running a GT45R turbo using 36psi gauge boost, using C16 fuel only (and that is on our dyno's that read lower than yours) car trapped 167mph in a RX3 with a 28x9 tire. Only used 9000rpm though, bridge ported with 13B-RE inlet manifold and adapter plate.
I have a couple of customers who run C16 at similar mph and similar rwhp figures on just C16 but with 13B's and all are water injected to make the steel apex seals reliable long term.
AFR's in the 10's Timing in the single digits.

I'm not being shy, but apparently we don't both know the numbers as mine are not the same as your. But honestly I don't care what other people "claim" to run for afr's, ignition timing, boost levels etc...there are too many variables, mix that with a bunch of half truths and you'll be really confused.
9000rpm is also not the same as 10-11k rpm. Water injection as good as it is (and I'm not being sarcastic) is not a real lubricant.
167mph is respectable, depending on the vehicle weight. At roughly 1800lbs it only take 640hp, but a full weight FD would need about 1060hp to trap the same mph.
Do you have any dyno graphs to share? Vehicle weight? How about the dyno graph for the GT45.
