Mag;
The discussion here is the ability to make 100 RWHP for a street 904 (360-270 don't matter), versus my comment that you will not get that horsepower from a 904 street motor.
You already said to consider lighten rods than Carillo's, different pistons profiles,titanium valves,etc,etc, perhaps you will need a properly design brand new head from scratch. So with unlimited budget like you seems to have maybe will be doable like Fred said.
Him and I spent many hours talking about that possibility for a 904 and come up to the conclusion the the expenditure will be astronomical, without any guarantees to achieve the target.
Besides that how many people ( besides you) will have interest in a 100 RWHP 904, that will not last many miles.
If you want 100 RWHP reliable HP street motor consider a 988 or a 1087.
See my sig.
So I don't need to post any dyno runs here,maybe I'll wait for your dyno runs when you can show me and the rest of the members that your target was accomplished
