It's potential gains won't be realized until you start spinning it much harder where smaller units start to lose efficiency and create more heat.

What Oldman was trying to tell you is that you will run out of fuel system before you ever tap the full potential of that F1. If you were only planning to run 7-9psi, then you could of just went with a D series. F1 isn't even getting into it's prime operating speed till about 15psi+. You will likely take a hit on low end spinning that unit for only 7-9psi. It's no different then properly sizing a turbo for the application and goals. If it didn't matter then procharger would only offer 1 or 2 units.
I plan on forged pistons and rods and going for 900+ in the next year, that's why I went with that head unit.

If I can get 750 rwhp out of this set up I'll be happy until I forge it.

Just remember - "boost" is a measurement of restriction. The number of you want to look at is the CFM being moved.

Lets say you put a out of the box P/C setup on a stock engine and tune it and its running 10lbs. A year later you do do a cam, headers, and intake manifold. Since the engine is able to flow much more CFM, the restriction is less, so boost will go down on the gauge, but CFM is going up (and making more power).

I am over 700wheel (SBE, stock cam, stock intake, LT4 fueling, E85, and a little meth) and have yet to see over 10lbs
