P2c/P1c is the pressure exiting the compressor/pressure entering compressor (atmospheric)? If so, I can expect to double boost pressure at rpm's higher than roughly 2000 rpm. (That's 14.7 psi of boost). Little to no boost at rpm's less than 1500.
I haven't figured out what the units are on the semi horizontal curves are with the numbers 65853, 91977, etc.
Thank you for taking the time to work it out and post.

Yes I've put the red line roughly where I think it'll work out on a 3B. If you wind up the fuel then you'll get boost sooner, if you have conservative fuel settings and/or a more restrictive exhaust then you'd get boost later.
Those arcs are rpm of the compressor wheel. 65,000 - 170,000rpm. Pretty quick really.
