    Wow, I am surprised its going out located there. I figured it was located in the engine bay being exposed heat. I wonder how long the underhood kit pumps will last.

    That's an interesting thought...

    so, my question to you is, is there a benefit from having duals as opposed to a single if total flow is equal? are yours mounted near eachother? i could see if you had them separated, lke what i was trying to say earlier, 1 maybe post fmic, and one pre tb. but i dont see the advantage if they are inches from eachother

    does that make sense?, its kinda late

    I would venture to guess better atomization than a single DO12/14? The CM10 nozzle isn't much for atomization as it is, although better than the DO10 I used before.

    They're separated.
    I did improve my 100-200 km/h Vbox time after I installed the duals.

    Here's a pic of them:

    yea that makes sense then. I always like the idea of seperating them just like that

    wouldnt spray pattern be effected if both nozzles are spraying to close to each other? Maybe thus generating worse atomization?

    maybe thats why your fuel trims were pretty much the same if i remember correctly while i have 1 bank running richer on meth than the other.
    Could be too much difference between banks i terms of trims triggers missfires.
    On the other hand you had missfires to on procede rev 2.5 . did you solve that?

    I haven't been able to try the car after I installed the new spark plugs.
    My meth system is also of the car right now, as the pump is kaput and my DO fittings are leaking...
    I hope to fix the meth as soon as possible, cause I really want to see if the misfires are gone.

    ...and on top of that I'm in China right now for some work... Click here to enlarge

    Going dual nozzle and having them trigger at different stages basically helps in preventing bog/quench. It also helps to save meth at the same token.

    but you cant do that on a just a "T" line, you need a true dual like i had, and im tellin ya, more meth is not the answer, it will eventually blow out the spark

    Yeah I agree having two pumps is the best way to go for sure. Better atomization of each nozzle. I think you were the only one that ran that setup.

    Correct, it is the same as drinking too many G&T.

    It's possible to make it work with only one pump if you're using dual solenoids with dual boost switches.
    But in my world that's just more stuff that could stop working, and that even includes a dual pump set up.

    I can't even get a single pump setup to work 100% reliably let alone a dual pump lol

    lol So true its not even funny! Two pumps would make me worry even twice as much..I have dual solenoids working so my setup is almost a true dual setupClick here to enlargeClick here to enlarge

    The pump appears to be holding up perfectly fine for now. Maybe I'll replace all the engine bay fittings with the AM compression fittings, at least it will offer me peace of mind.

    It can work but the atomization would be compromised since the pressure of 200 psi to one nozzle drastically decreases with an additonal nozzle added to the line. Having two pumps you get the true injected ml/min and atomization is so much better when pressure is at its peak from pump. Not alot of people will do a setup like this as it makes things more complicated and more things to go wrong.

    While we are on compression fittings, I think I found the ones that we need for our solenoids and the rest of the 1/8 NPT female parts that require a compression fitting...
    These are pretty cheap...I tried looking for identical ones made in nickle plated brass but came up empty, but these look to work for sure!

    Guys I found the one shop stop for compression fittings that sells to the public!!!! Forget about the link I gave from summit racing!! These are better and are nickel plated....Remember when you order use 1/8 npt threads and we are using 6mm meth lines and the metric threads....DO NOT ORDER THE G-THREAD ones

    Calling these guys tomorrow! If your interested look under: Rapid fittings for plastic tubes

    Nice! I want to replace my nozzle holder and solenoid fittings with these compression fittings. Won't have to cut line or do other nonsense any longer.
