as far as clutching is concerned,, ASK SOMEONE ELSE!!! i could NEVER get the science of clutching right.. Nitrous will usually make 400-500 RPM increase, so you need to install heavier flyweights to take care of that problem... As far as the timing retarding, you'd have to ask someone who knows all about those cdi boxes,,,but,,, I HAD TO buy a special cdi box for my 98 SRX to get the motor to run at 10,000 rpm's to race!!! I got a lot of running around to do today b/c of that 2 weeks in the caribbean,,,but,,,,it SURE WAS NICE!!! TTYL!
I have to work all day, i'll call tonight. I'm not sure of the time difference. Its 11:20 here now. I'll call around 5:00.
I must have been sleeping last night.. I came down with a HORRIBLE cold or something on Sunday and I've been home sick since!!! Try and call tonight and I will talk with you!
If your sick i'll leave you alone. I won't get the kit till this weekend anyway. I'll see whats all there and call next week. Hopefully your feeling better by then. Take care...Jeff.
I've got the kit installed. Before i test i was wondering if i should run pre mix in the external fuel tank with the C-12?

yes
the NOS system is after the oil injection
and when would you need the most lube ? when you are adding 30 to 45 more HP
so definitely add oil to the fuel
pics, we need pics
and specs, what components to you have

I havn't intalled the fuel tank yet but here's what i have so far. I'm useing size 18 nitrous jets and 22 fuel jets. I mounted the battery in the back of the boss seat and ran the wires under the seat. The relay's are behind the left panel. Switches are on the left side of the cowl opposite the ign switch. I've ordered a fuel pressure guage. Not sure were to put it yet. I'm also thinking of istalling a co2 cylinder to hook up to the nitrous bottle. That way i don't have to rely on the heater. Its not all there yet but hopefully i'll be testing early next week.

looking good
how does the co2 bottle work?
I had a small compass installed on my dash when i bought the sled. replaced it with the fuel pressure gage. and ended up cutting a whole opposite for the nos pressure.
If i ever sell it less NOS, i will find a totaled sled and replace the dash panel
so there aren't open holes, otherwise it will all go complete

My understanding the c02 keeps the bottle at the desired pressure all the time and pushes the nitrous out. The c02 will not loose pressure with temp change thus eliminating the need for a heater. The c02 is not combustable so when the nitrous bottle is empty of nitrous it will have whatever pressure is left in the c02 cylinder but will not harm the engine. The only problem is you have to fill the c02 everytime you fill the nitrous. Unless you use a big c02 cylinder.

that is very interesting
not sure how it works. if there is a barrier between the gases, or they are mixing, which in turn affects the partial pressures of each compound. not sure if the resultant NOS flow vs. fuel flow is calibrated then. hmmmm
Keep us posted on this
another interesting concept is with one of the "turn key systems" that uses a pressure regulator calibrated down to about 500 psi ( which is about the lowest pressure you would see with N2O in cold conditions ( 0 deg celcius)
the jetting charts are all different of course becasue you are pushing 500 psi instead of 800-1100psi, but you are always consistent, pushing out 500psi, even if the tank is at 550psi, or 1100psi.
the other solution (which you know i am using) is controlling the temp of the N20, which in turn controls the pressure,
but with various speeds, and convective cooling via the airflow across my tank with my tank placement, it is tough....
keep the info coming. I want to hear how much weight you add to keep them R's down when you hit the juice

C02 is a gas, nitrous is a liquid therefore they do dot mix. There is no c02 coming out of the nitrous bottle till the nitrous is gone. The c02 stay's on top of the nitrous pushing it out. (So i understand) It will just spray co2 when the bottle is empty of nitrous. Nitrous and fuel flow is consistant till the bottle is empty. I was told this from the shop that filled my bottle. They have been useing this system for a while already and said NX is has been doing a lot of testing with it with a lot of success. Because there is nobody local filling c02 i'm sticking with the heater for now. If its going to be a problem maintaining pressure i'm getting the c02 system and possibly a filling station. I'm already looking at getting a nitrous filling station for my buiseness.

that makes some sense
their statement need to be clarrified some though . ( nitrous is a liquid and co2 is a gas at a particular temp and pressure.
if the pressure falls ( below its partial pressure), the nos liquid goes to gas.
thats how we use it.
no disagreeing at all , just trying to think this out loud i guess
the N20 properties act similar to propane. if you exceed the partial pressure it will condense to a liquid ( filling a outdoor grill tank) this allows suffient mass of propane to transport in a small tank. same story with N20, jsut at a higher pressure.
the C02 at that same pressure and ambient temperature must still stay as a gas....hense the very cold refrigerated trucks that transport liquid C02.
I will try to find the pressure/temp curves cuz I am curious.
THANKS justaviper

You have a point. If the nitrous is vapor at the same temp and pressure the c02 is vapor or opposit, both liquid at the same time it will not work. All we really need to find out is at what temp and pressure c02 changes to liquid. I would emagine its pretty cold. The nitrous comes out as liquid but its fogged out of the nozzles in a vapor. I don't think its vapor in the lines. I could be wrong though. I'm still just learning.

Well i took it for a rip. First pass went well except for the ratcheting track, (anti ratchet drivers are on the way) rpm's were 9000. Second pass same thing. Third pass it lost power and started to bog. I'm not sure if it just over shifted and didn't recover or if there is a problem. Clutch is warm to the touch not hot. I checked the plugs and all is good. Maybe a bit rich but thats ok. The fuel pressure is at 12psi i'm thinking its a bit high?? Anyway it all looks good and the pistons are still in it lol. If the weather is ok tomorrow i'll try it again. Oh and the bottle pressure was at 750psi. Maybe i should have let it warm up a bit. Got to excited i guess. I wasn't sure how mutch to premix the race fuel. I used 1/4 litre for 1 gallon of fuel.
I figured out why it bogged on the last pull. The bottle is empty!! That didn't last long. Anyway i'm getting another bottle so i'll have a spare. Also working on getting a filling station. Another thing, the fuel pressure is 12psi but it drops to 9psi on the throttle so i should be ok. This is fun stuff!! But now i have to go the whole weekend without it. Oh well its raining right now anyway.

awesome justaV !!
welcom to the dilema of runnign out of NOS WAY TOO FAST
I have a purge valve on my system and made some short video clips of the spray, adn showed about 5 friends. and on my trial run I made it about 3 passes and ran out too !!!!
the tank does not last long. use spairingly.
you need two tanks for sure. and make sure they get filled properly.
my NOS filler does not have a pump on his large tank so he has to freeze my bottle and fill three times to get it full.
if you get a "station", get the pump.
my jetting charts are for fuel at 6psi, and NOS at 1050psi
once you cannot maintain about 850 psi with the heater, you are starting to run out of N2O
I found that the long nylon line to my fuel pressure gage , running near the engine, warms the air up which is caught in the line. This raises the fuel pressure until I hit it, it then falls down. I may try to purge the air out of the gage line. I assume fuel can enter a fuel pressure gage. this should help my pressure some. I also thougth about addign a fule pressure regualtor close to the fule solenoid ( all this to better control the mix)
on a long run sometimes, it pulls at 9000-9200 but I get a fluttering. Bruce at CBperformance says that I may be blowing out my plugs. Not sure how to improve that condition.
what plugs are you running. you want a cooler plug. BR10ECS is working fine for me on and off the NOS. the normal srx plug is BR9ECS. the "C" plugs have a larger electrode that will hold up to potential detonation/heat of the NOS burn.
Let's see more pics of your setup !!

I don't know what the premix should be either
I assume a standard mix ( which is what.... 32:1 or 50:1??)
I just " added a little" to my tank to be safe vs. just gas
the 100 or 110 has lead so there is some lubrication.

I had to fab up a shield for the fuel tank. It got so hot after a ride i could barely touch it. (NOT SAFE) I'v installed the fuel pressure guage beside the ign switch with an adapter and 5/16 hose. I have a hose coming so i can remote mount the nitrous guage. The heater, solinoid and fuel pump switches are on the opposit side of the ign. I think i'll have room there for the nitrous guage too. I'm running BR9ES plugs. I havn't done enough testing yet to see if there's a problem running them. So for now i think i'll stick with them. But ya i think a colder plug would be safer for long runs.
