Has anyone got any ballpark figures of how big is big enough for water injection pump line diameters?

My Aquamist setup wont flow enough for the 500-600cc per min target I want, so I'm upgrading with an WRC pump I have which does 6.8bar max pressure and has a max flow of 7.6 litres per min.

The question is, how big will the water lines need to be? The water tank outlet is only 8mm, is that big enough or will I need to change that?

The current lines from pump to jet are a mix of 4mm and 6mm line, will they need increasing, or?

Thanks

 

i used 6mm and it works for 1500cc of water from a coolingmist 150psi pump

 

Should be fine then, brilliant. Worth leaving until I can test it at least.

Thanks
