Thanks for all the advice. A few questions arise.

What compression ratio allows for big boost? 7, 7.5, 8:1? It would not be hard to fly some material off the top of the pistons. Actually, it would be pretty easy. I think the edges of the JE's are a bit sharp at the valve pockets anyway.

How much cam is too much cam? Where does boost make up for the fall in torque due to duration and lift limitations? I see builds with SC or 964 cams. From a NA perspective, these are really mild. There are grinds that build just as much low-end torque and a ton more high rpm torque. I would think that combined with boost you could really build some big HP numbers.

I will keep reading this sub-forum. There is some good info here.
