Dual CM7 (superatomizing) nozzles and 94 octane

Just put an order through for these new awesome nozzles. Thinking of running them together instead of one single standard M8. Dp you guys think this will work at all, is overkill for 94 pump, or could there actually be a benefit?

I was gonna run a single M10 but Noe that cmgs came out with the redesigned nozzle I thought dual CM7 might be a good way to go, even before RB Turbos arrive.

Thoughts?

It's probably just me, but I have no idea what you're talking about. Can you please elaborate a bit and tell us what these are? Are they for meth, nitrous, or just direct fuel injection nozzles, or ?????????????

Meth injection nozzles..new redesigned ones that provide a lot better atomization characteristics than standard ones, of which I have the m8 in my meth setup now..

probably okay with a controller, if it is too much it should pull back

trick to dual nozzles... 2 check valves.... or 2 solenoids. One before the T will make for air in the line every time and loss of Prime...

I recommend 2 check valvesat the nozzles and a solenoid before the T. This will slow the meth down just a bit but keep the lines full of meth at all times. Air in the line at 18psi will make for an ugly run and ugly timing logs.

I know as I struggled with this issue and nobody could figure out that when you have 2 open holes past the check point that fluid was going to vent and drain.
