It's really hard to compare how a cummins I6 with a log manifold is going to spool a turbo VS a V8 with a custom header to accomodate a turbo.

Anyway, just to answer your question anyway, the WH1C (same as HX35) on my 94' completely bone stock got to about 17 PSI by 2000 or so RPM.
After I added enough fuel to make ~100 HP over stock (175 stock) it spooled to 30 PSI by 1700 RPM. And after I had 325 RWHP it spooled an HX35 to 37 PSI by 1600 RPM.

Thanks, I know, just trying to get an idea. Another guy on a Cummin's forum was the same as you. Now I need some auto and HE guys to step up.
