Hi Ed,

I like your thinking, and I enjoy reading your posts.

If, under boost, (15 psi in this case), we could double the air packed into the cylinder before the intake valve closes, then we "could make" double the power.

But with 12.5:1 compression, would you then think it would detonate itself to bits? Or the ignition timing has to retarded so much that the compression increase is hardly worth anything?

Note that they are running .900 valve lift, since the heads are the restriction to power.

Considering it makes nearly 800 on 12.5:1, I would be happy 1000hp on 9.5-10:1 on 15 psi for a street car. Imagine the manners, something your wife or good friends could drive with 5 psi.
