I forgot about that story, but as Mark said, breaking the 300HP barrier
requires significantly more effort than what the basic BOS stuff gives.
And from what I can tell, you're not going to go much past that number.
I'm not knocking the number. I wish I had it. But it does require a lot
of cost/effort, and what might be even worse than that is post install
maintenance (ie. leaky injectors).
To put this all in perspective, an F1 engine has 3.0L displacement, albeit
via 10 cylinders, is normally aspirated, and makes 1000HP.
