From memory, my old Volvo had more of an on/off switch than a gradual power build up in regards to the turbo.
In the 122hp 1.4 TSI it builds from 1500 to 1750, then there is full torque (= boost) until some k rpm.
In the 86hp 1.2 TSI it builds from 1700 to 1900, then see above.
In the 105hp 1.6 TDI it builds from 1000 to 1500 90% of the power is available from 2500rpm, that's 140 in 5th. As a result it feels much more powerful because an oldfashioned engine wouldn't have that much at such low revs... but then it dies from 4500 :lol:
