ok, 20PSI~=1.4 bar. Wouldn't you want to be between 1.6-1.8 for the sweet spot? Ug, I must be reading this wrong...

Pressure ratio is the Y-axis. Unitless.

For a rough estimate thought, multiply those numbers by 15 to get near the PSI rating...

EDIT
i mean subtract 1 and then multiply it by 15

I've been doing it for like 4 years.

Compressor maps are a very tricky thing to base a real-world decision on. We don't know what is generating the curves (what engine/displacement, what ambient temp, ect.) and we'll never know the differences between two different manufactures.

I have known people who have run crazy high boost on TD04 turbos, some in excess of 22psi.

Zak I don't think you should have any fears of running your vf30 at 20 psi. 25psi might be a bit over the top however, even with alky injection.

My boost gauge only goes to 20
