1361+NOS
Need some help.I am running a 1361 kit with Muzzys new Stealth Nos,I also have a pc111r with the Muzzys 1361 map installed,and a sidewinder exhust.First time on the spray I had it set up as per instructions and no improvment.Called Kurt at Muzzys and he said to invert the jets,they were 16 fuel and 14 nos.I changed them to 14 fuel and 16 nos,still no improvement,but I am starting to get a little nos pop out of the exshust when I shift.I do have an air shifter and a high flow fuel pump,which may make the fuel side run richer.They give you a setting for the fuel reg. but there is no gage.If any one is running this set up please help.Every thing is working selenoids are firing and there is nothing blocking the lines.I'm going to try 16 fuel and 20 nos and 3degs out of the timing.

Are you sure the nitrous solenoid is firing?

What's your bottle weigh? Pressure is related to temperature, but weight is the critical factor. Same thing happened to me first time I tried it - bottle was less than half full.

when you say no improvement what does that mean; no quicker ET or no change in MPH or both? You should at least see some MPH on the spray. Have you dyno'd it to see whats going on? I would think a 75 hit would be very noticable

Mack,
I'm assuming that you have the dual bottle setup, that both are filled with 1 lb (900 psi at 85-95 deg. F) of N2O and that you followed the directions regarding the siphon tube locations. The fuel pressure adjustment is very sensitive. Please re-check the setting on top of the red regulator. The correct dimension is .437"(7/16") from the TOP of the adjustment screw to the top surface of the regulator. Any larger and you can reduce fuel pressure easily and over lean the engine. Remember, the kit is simply plumbing and solenoid valves that deliver the fuel and N2O. After that, it is simply tuning. In that regard, the 16N, 14F is a solid 50 HP. The feedback that we are getting (as well as our testing) is that this is VERY noticeable. Be Careful. One customer who also has a stroker engine is very happy with a 18N, 16F setup. More than a two jet spread is pretty lean and with compression could get you into some serious detonation. And to any one else concerned, the stock pistons will fail above 70 hp. Regarding Curt, yes he is sales person, but he fields most of the feed back calls on this kit. Therefore, he has a lot of comparative information to pass along. True he has not ridden with the kit, but he has talked to several people that have.
Doug

I do have a two bottle set up,yes they were filled and over 925psi.I had a very little increase in mph about3to4mph.not much for a 50 shot.NOS tech info shows HP gain 4-cyl motorcycle 14n=24hp,16n=36hp,18n=48hp,20n=60hp.These are with a hi-output pump running the same size fuel jet.They also state NOTE:Higher fuel pressure applications will require a smaller fuel jet,however,the nitrous jet will remain the same for the given horsepower gain.I will try the 18n,16f,combo first.But I think the 16n,14f,should have shown some et especially for a 50hp shot.The bike has a slick and a bar,and has gone 8.85. I did notice the pipe is real black after a NOS pass.And Curt has been very help full,I had a bad switch with the new kit,he helped me work figure out the problem and sent me a new one.

Mack,
The chart in the NOS book is a "conservative estimate" (their words) on a carbureted engine. It is a calculation based (only) on a BSFC for a given amount of fuel through the (fuel) jet. It does not take into account cooling effect or any "make-up" of poor fuel efficiency in the base engine. In other words, that chart is nothing more than a WAG. We call those jets a "50" shot because that's what they gave on our bike on our dyno. Like I said earlier, it's tuning. If all indications are that you are rich, either take away some fuel or add some N2O. I can tell you clearly, there is a BIG difference between how a rich bike runs and the way a correct one does.
zxlnt,
Yes, we have the "nitrous" pistons available in the 85.4mm (1270) size. And no, they are not Wiseco.

Thank you Doug,I have run NOS on a dragster but the system was already setup for me.7.09sec 189mph.I'm going to step it up and go for it.Hey winters almost here anyway.If I melt the pistons it will be a good winter project.By the way how is that progesive/retard setup coming.$$$???.
