Anyone wanna see what Ford has done with the new 2020 f250 turbos? I can tell you they are gonna spool SUPER fast... but doubt they are going to make anywhere near as much power as the 15-19 turbos when tuned.
They went back to something very similar to the 11-14 cab and chassis turbos. They are dual ball bearing and are much smaller than the 15-19 turbos, 54mm compressor with 55mm turbine. The vgt system is also completely different.
Here are some pics.
