Hallo,
folgende Infos sind aus der Doku zur Trionic 5 herauskopiert. Dort finden sich auch die Maps zu den Ladern:
Garrett T25 specifications
Weight: 7,5kg
Compressor diameter: 60mm
Turbine diameter: 65mm and 59mm
Bearing span: 37,8mm
Moment of inertia: 5,4x10-5 kg/m2
Oil flow: 1,7L/min / SAE30 / 90C / 2,75bar
Compressor wheel: 54mm 55 trim, A/R 48
Turbine wheel: 53.8mm 61 trim, A/R 49
As you can see the T25 (trim 55) can flow 18 lbs of air per minute @ pressure ratio = 2 and efficiency
will be ~65%. This 18 lbs/minute converts to about 260 cfm. The maximum efficiency zone (73%)
reaches up to pressure ratio 1.9. This would be ~0.9 bar overpressure.
In terms of usage the T25 can take us up to ~1.1 bar boost pressure and bring up to 250 bhp.
--------------------------
The TD04-15G from the 9000 Aero can flow more air than the “little” T25. Looking at the map we can
see that the TD04-15G can flow ~428 cfm @ pressure ratio 2 and efficiency of 60%.
Also, the maximum efficiency zone (76% vs. 73% for the T25) reaches up to 1.9 pressure ratio with
would be ~0.9 bar.
In terms of usage the TD04 can take us up to ~1.4 bar boost pressure. The TD04 can bring up to
~330bhp.
