    Question Hi & help with Nitrous?

    Hi, I must say this is a great site, glad to have found it and I hope that someone can assist.

    I've read and re-read posts regarding nitrous installs, but I can't seem to pin down the problem with our pwc in any of them.

    My husband and I put our own dry nitrous setup on our 07 GP1300R. We ran two nozzles which point into the intake on either side of the center throttle-body. When we run a 28 jet it seems to slow it down almost like its on the limiter or the ski is bogging and then it will speed up for a second just as we let off the throttle. We have 14/20 solas, riva fuel controler, a D plate, a jet works valve, an Intake grate, a homemade air filter kit and a shredmaster ride plate.

    Do we need smaller jets? Is there something else that needs adjusted/modified/upgraded?

    Any suggestions would be greatly appreciated.

    Thanks

    How do the plugs look after you spray it? Thats the first thing you check. Nitrous is cool.

    Yep , Happy to help

    What do you set your fuel controller on ? 11 ? I have different jets you can use, but it sounds like your running way lean. Do you have a EGT on it ? Are you running 2 .028 jets in each nozzle or one?

    When I ran a .029 jet and just using fuel controller to richen, my jet was about 36 inches away from intake path.... I had it going into 1/2 pipe so it could warm some and expand.. then it would mix with ambient air to make it super oxygenated air....... If I sprayed directly into cleaner, the .029 jet was too big. You can post details here or give me a calll and I will help you get it sorted out.

    Give me a call 252-341-5126

    Sounds like lean to me. You can not spray a "dry" shot on a GPR without having a way to increase the fuel.

    Its not like a LS1 camaro that has a mass airflow sensor to add more fuel when it senses more air flow.

    I run a "wet" kit. With a stand alone fuel pump and fuel tank. That way you know its getting the right amount of added fuel along with the nitrous. I have 3 nozzles that inject into each cylinder. Each cylinder gets equal amount of nitrous and fuel.

    I think what he is doing is same thing i was.... A dry system on EFI ski is easy way to get a few extra mph without any plumbing issues.
    I ran my pots 2 2 1 5 on my controller when I wasnt running nitrous.... When I knew I was going to make nitrous passes I would spin pot three to 11 so it would be 2 2 11 5 I experimented with having my nitrous relay activate my controller by disconnecting the ground... but it wasnt effective. What he is doing is good for 3-4 mph depending on how its propped.... btw... what prop are you running ? I ran a 14-25 with setup like your doing. What are your rpms on and off nitrous

    The fuel controller is set at 8, no EGT (yet), 1 jet - we have various sizes of jets .018 +, have ran it with the .028 and as you say 'too big'.

    Dynafly 14-20, just had it pitched and rebalanced to a 14-22

    Danger1049 - spark plugs look as if she is running too rich, which goes against general consensus.

    Ronn25 - As David said, just trying to get a few more bhp, not wanting to compete with jet boats or Camaros just yet.

    Again thank you guys for your quick responses, food for thought.

    We will do a few adjustments as per your suggestions and take notes of rpms etc. tomorrow. David, I will pass your phone number to my husband as he talks the talk better than I do.
