Well it is known fact that radial rotary pump (VP44) reaches almost 1000Bar in injection event, but that is whole other story with so much stronger hard lines compared to that spaghetti on 606 and steep DI "cam" profile. I think you will be surprised with how low pressure you will measure on this engine.

Ad that duration time... CR may have bigger pressure but take this. Both of those engines need lets say 120cc/1000 to make 200kW. If one was much slower to delivery this fuel it would have to advance maybe 50 maybe 80°BTDC to complete injection event before pressure drops after piston reaches TDC. So they must have simmilar time of injection, CR od IDI matters not. Both engine use simmilar SOI in range of 20-30°BTDC so assuming that injection takes 1.5-3ms is good guess.

Here you have CR duration table.
