Just to clarify for people, since many are interested in these two turbos respectively:

2.5XT-R = 60.0mm Turbine Wheel, 71mm XT Compressor wheel
1.5XT-R = 56.5mm Turbine Wheel, 71mm XT Compressor wheel
Both 49lb/min

The idea of the 1.5 was to aid in spool for smaller displacement engines while giving back some upper-end power.

1.5XT-R TS = 56.5mm Turbine Wheel, 71mm XT Compressor wheel
47lbs per min.

Does anyone know why the twin-scroll is rated at a lower lbs/min?


I can't wait to start seeing spool comparisons between the twin vs. single scroll.
