Default multi nozzle meth setup suggestion needed. - 10-03-2014, 01:44 AM

Hi guys

I have cooling mist 200psi pump, FSB controller, Valve, tubes etc. I was using cm14 nozzle and the car performs strong with RB turbines. Now I plan to go next level, and the reason I want to add more meth is that gasoline quality is not the best here.

Any idea what should I do?

I sow lot of threads before in this board but Terry deleted all old threads so forced to ask again.

Thanks
Taron

if you are going to go dual nozzle I think terry recommends a cm10 + cm5 or a combo of cm10 + cm7. the dual nozzle kit is available on the burgertuning website

spraying before or after turbine is producing more power ?

CM 7 and CM 5 Should be fine.

When I had RB's I just did CM14 single nozzle.

Would there be benefit to spraying water with one nozzle and meth with the other? Maybe you could tune your mix on the fly, or have more of one spray at low/high rpm or boost? Or maybe water before the turbo & meth after, or vice versa. Just brainstorming here.

would a cm 12 and cm 10 combo be too much for fbo+ RB turbo car?

If you are worried about timing..... up your water ratio.
Pump pressure will really take a dive with that combo.... but your call.
Instead of speculation just log.

You're over 3 1/2 years late to the party. Haha But yes, dual 7cm over a single 14cm. That's dependent also on your setup wether you need that much volume.

Depends on the power goals.

I usually rec dual Cm10 for anything over 600whp.

I used to run 2 nozzles but am not a fan of it now.
- more connections to leak/monitor
- smaller jets clog easier
- cost
- if you don't run a second solenoid then the meth will get siphoned out of both lines from the "T" to the jets. I think some guys have done loops to prevent this but not sure.
- due to pressure loss you can't just add the jet sizes together as the overall amount will be far less
- I drilled and tapped the outlet of the intercooler to get the best distribution. I will take this over any perceived gain with spraying closer. My trims are identical between both banks.
- You can spray more on these cars than most of the sites recommend. As long as your trims are not bottoming out then as I understand it the fuel in the w/m is accounted for.

Hi Payam! Ok i changed to the PHOENIX RACING chargepipe with dual CM10 nozzles.

Need some advice, when running dual nozzles, does the length of WMI hose from T joint to the bungs affect anything? also, Iíve noticed that thereís a difference in bank 1 & 2 trims when the meth comes on, itís consistently 8-9 difference, am I doing something wrong?

I got to your email, send me pics of your setup since we're talking about it.

Tried a DO14 once and the trims were terrible.

One bank got very little meth. The other bank got loads. I imagine the big dropplets just followed the air within the manifold to a very large degree.

Yes the length is important if running dual nozzles with only one solenoid. All the meth will drain out from both jets up to the "T"...read my post above. I have heard that a loop in each line after the "T" may help with this but I never tried it. FYI I am now using a single CM14 that outputs 1100 ml/min tapped into the outlet of the intercooler and both banks of my trims are identical. Also not a drop of meth leaks out of the jet with this setup.
