n20 help
n20 help have H/C, longtubes etc......and a Cold Fusion N2O wet kit with their solenoid style bottle opener...tried the 150 shot today but seems like i'm runnin out of N2O...initial hit is very hard and feels good but goes away right after acitvation, also get a little surging before the problem starts...all wiring good, relays good, bottle pressure 1000 psi, window switch works obviously (MSD digital).....no KR, wideband shows very gradual leanout but i dont think it's fuel related....didnt have any problems with the 100 shot....is the solenoid botttle opener holdin the 150 shot back ? also have a Racetronix pump, and am using a NX Shark nozzle with jetting for a NX kit, so the N2O hp is wheel rated....thanx
Problem:
Surging
Things to Check:
WS Settings, bypass and see if problem still exists. Adjust as necessary.
Fuel Noid Operational- unhook line place in jar, N Bottle closed arm and activate system with car running, fuel should be spraying out. Check, change filter.
Nitrous Noid Operational- unhook line, hold away from face or persons, bottle open, with car NOT running, arm and activate should see a big cloud spraying out of it. Check noid filter screen, pull inlet fitting out, looks thru it, if its dirty clean it. Add separate nitrous filter.
Wiring- check on smaller/larger shot size, if problem is gone, rule out wiring. If problem still there, start tracing wires.
Bottle Full- Make sure bottle hasnt been emptied down to the last couple pounds. Nitrous systems dont like sucking the crap from the bottom of the bottles too well. generally you will have about 3lbs left in a 10lb bottle when you go to fill it.
I empty my bottle completely and then have it vacuum pumped prior to filling so I dont worry about what is or not left in the bottle. Cost more, but I dont have these issues.

i dont think it'a mechanical problem...N2O noid works obviously and the fuel noid works because i can see the extra fuel dumping in on my wideband.....like i said everything works fine on the 100 shot

And you had no surging running the 100hp hit? If so, like cat said you may be running out of fuel, or dirty/clogged fuel filter. One way to check, put the 100hp jets back in, then if it goes away again, you've just eliminated a whole bunch of stuff. Your bottle opener should be able to handle a 150, IIRC they are good for 180. You can bypass this noid and try again. keep at it you'll find the little gremlin. Keep us updated.

Im running the cold fusion kit on my car. I had it jetted at .048 and .026 to get the best result and based on their calculator that is way rich for stock fuel pressure, but it works perfect.
I tried a bigger shot based on their calc and my car surged, looked at the A/F and was headed lean, havent tried it figuring stock fuel pressure since, found best results on their calc at 45 PSI for the fuel side. just my personal experience....

I wouldn't think the opener would cause that much restriction. The newer style solenoid ones like Edelbrock and possibly Cold Fusion are using are a .310 oriffice. And even the older NOS solenoid one was .250. Seems like a really odd problem. Maybe Cold Fusion is using a smaller solenoid as an opener than Edelbrock

so what are the chances of that happening again ? if it was the valve, i dont want to be at the track not being able to run the N2O cause the damn valve wont open all the way
It's really hard to say. We don't even Know for sure if this is the problem, maybe a sticking main noid? You'll have to stay on top of things until the gremlin is found, or maybe it left allready.
