On a Ford Focus 2003 1.8 TDCi 115bhp, at what RPM does the turbo kick in?

Maybe a better question is when does the wastegate open, letting the
turbo come up to speed?

“A turbocompressore integrated Garrett to variable geometry with the
exhaust manifold. Valve is not necessary one wastegate, seen the high
efficiency of motor and the electronic control of the
turbocompressore.” from

Appears to be all computer controlled…

“…ultra high-pressure second-generation common-rail injection system,
variable-nozzle turbocharger (VNT)…” from

“Taking advantage of exceptionally high turbo pressure rates, the
Duratorq TDCi achieves a peak steady torque of 250Nm at 1850rpm. But
the driver has even more torque available on demand, thanks to a
sophisticated transient ‘overtorque’ feature for improved performance
response.” from http://www.dealernet.ie/features/Ford_Focus_TDCI.htm

“And there's a great torrent of torque on tap just as soon as the
turbo spools up to speed…” from

This implies that it’s not when the turbo kicks in but how quickly you
try to kick it in.
This is why some race car drivers ride the brake pedal and gas pedal
when going into a corner; keeps the turbo up for a quicker exit.

“With today's direct-injection technology, the downsides of driving
diesels have all but disappeared…” from

( the vehicle is not available in the U.S.)
