I was a bit concerned if our instruction stated that you should put your water jet by the TB, that was the reason I asked.

There occasion that water can be placed by the throttle if inlet tract cooling is not as important. There is still some distance betwen the TB and the inlet valves, some evaporation will still take place.

For knock control. TB injection is effective.

What is your aim to achieve with water injetcion?
