I guess you misunderstood something.
Motorunterzetzung DB 601 A = 1:1.55
Reduction gear ratio DB 601 A = 1:1.55
1 ata = 1 kg / square centimeter. I am not going to convert this to PSI (0.454 kg = 1 lbs, 2.54 cm = 1 inch, have fun
) but keep in mind the British used relative boosts, ie. (+) 0 PSI = 1 ata, and + 6.25 PSI boost on the Merlin III is 1 ata plus whatever 6.25 PSI is in ata.
Bottomline, the Merlins always used much higher boost than DBs to compensate for smaller displacement. IIRC the 1.7 ata boost of the methanol boosted 605AM was something like +7 PSI..
