But the TDO4 doesnt even fall off until around 6500 rpms. A vf39 will hit full boost at about 3300-3600 rpms. This is hitting full boost at 2500 rpms and pulling to almost redline. The vf39 drops off just shy of redline, and both turbos will hit the same amount of power to the wheels.
my buddy has a vf34 on his 2.0l and made 282 whp and 272 wtq. and this guy made 277whp and 277 wtq. i would say they are almost identical. The vf does have more up top but i cant imagine that much more that you would really notice.
I think the 16g would be a great turbo but the 16g is double the price of the TDO4. and you only get a little more up top.
