Pre Turbo Injection - How Much and When to Inject

I can be sure that the turbo spools up much more quickly in the 10~20psi region than the 0~10psi. Probably, that's the work done by water.

Which stops me make it earlier is the worse atomization in the low DC injection. I'm a little worrying about the larger droplets caused by this, especially pre-turbo.

Im not too sure what my water pressure is set at now, i need to get a couple of pressure gauges to monitor that both systems are working and set to the same pressure.

I ve noticed and i think it may have been yourself that said if the pressure is set to high the HSV starts to behave strangely, like the flow is being restricted.


I want to set mine to the highest permissable pressure to ensure good atomisation.
