Default Aquamist jet flow rate

Richard, I've got the image showing flow rates for the different jets at different pressures. I'm wondering if the 0.3mm jet is the 3-scroll or 4-scroll? If it's the 3-scroll, what is the flow rate for the 4-scroll?

Thanks.

I need to track back on previous communications.

3-scroll = 68cc/min at 125psi
4-scroll = 98cc/min at 125psi

Hmm. Well, neither number matches what was shown on the Pressure vs. Flow chart I nabbed from you. It shows the 0.3 as flowing 155 cc/min at 125 psi. For comparison, the 0.4 is shown as 207 cc/min at 125 psi.

I'm trying to nail down my flow rate for my jets vs. my fuel injectors. Fuel injectors are (6) 508 cc/min @ 4-bar of pressure, and I have (6) 4-scroll 0.3 mm jets, one in each intake runner.

At 100% IDC (which I know I will never hit), I'd have 508 cc/min of fuel per cylinder, and I'd like 125-130 cc/min of water/meth. I know the hfs-6 gives me 20% adjustability on flow vs. IDC, but I need an idea of what the jets are flowing. The pump with my kit is at 160 psi, correct?

I believe the flow rate given was on our small piston pump, measured manually. Th figure on the chart is measured with the shurflo pump. The difference is probably due to the way the pressure is generated. Piston pump has pressure gaps between strokes compared to a diaphragm pump - injects less.

I can measure the 0.3mm 3-scoll and 4-scoll for you tomorrow with the aquatec pump for you just to be sure if the previous chart are calculated ot measured *only apply to the 0.3mm.

Thanks, Richard, I would appreciate that. I'd hate to flood out my motor first shot out.

I know my nozzles are the 4-scroll, so I really only need that measurement.

Interesting results on the 0.3mm 4-scroll :

125psi = 97-98cc/min
160psi = 102-103cc/min

tests done over 1 minute- 5 samples each.

And that's with the Shurflo, correct?
That amount actually works out really well for me. 102 cc/min is almost exactly 20% of my 508 cc/min injectors. So, a 20% increase would put me around 25% of my fuel.

It is an aquatec pump. I mention it earlier. I think you have an aquatec pump?

If that's what comes with the US-spec HFS-6 systems, then yes.

You know, it's interesting that there's very little difference in flow at the two pressure levels. Kind of nice, because (if I'm thinking right) I could run 35 psi of boost, and have nearly the same flow as at 0 psi of boost. Correct?

So, I'll go with 100 cc/min at my 20 psi of boost.
