what effect does water/meth injection have on a non-turbo diesel ?

[dvldoc]

Same effect, but less power, Allows a more complete burn of fuel and engine efficiency, you will get smoother acceleration and lower engine operating temps as well as the big time reduction in emissions and internal carbon buildup as well as soot throughout the intake tract.

You'll see around 10% more power on a regular diesel.
