update on $30 nitrous setup, RESULTS!!

Here are the specifics of my nitrous setup. 
 
I have a bicycle/ATV CO2 tire inflator, a needle for inflating basket balls/foot balls/soccer balls, some misc hose, and some 16 gram nitrous cartridges. 
 
 
I zip tied the tire inflator on to my handle bars on the left hand side so I can easily hit the trigger while keeping both hands on the handle bars.  I screwed the needle into the end of the inflator.  From that needle, I used a very small hose adaptor and then ran some 5/16" hose from there to my snorkel. 
 
 
I then tested it this weekend at Mud Nationals. 
 
 
Now, my quad is only a 250 cc motor, but I currently am running a 140 jet in it and had a set of 25 X 9 X 12 Super Swamper Vampires on the back. 
 
When running in thick mud, the quad would occasionally start to bog down in 1st gear, so I reached up and tapped the nitrous for a split second.  I was suprised that instantly, the rpms rose and I was able to continue spinning the tires through the rest of the mud hole.  I also found while running on tight trails in 2nd gear, if I came across some mud and started to bog down, I could tap it again and it would give just enough of a power increase to maintain enough rpms to use 2nd gear. 
 
Each 16 gram cartridge was good for about 7-10 "taps".  I went through 3 cartridges the entire weekend, but one cartridge was just trying to get everything working right, one cartridge was used to see how long it would last with keeping it pinned, and the other cartridge was used for normal trail riding.  So in reality, one cartridge lasted an entire weekend.
 
If I had to guess how big this "shot" is, I would have to say it's around a 2-3 hp shot. 
 
 
The CO2 inflator ran me $20
 
A 5 pack of 16 gram nitrous cartridges ran me $10
 
I had all the hoses and fittings laying around the house.

Yes I do.  Once I get back from work today, I'll put the pic online so everyone can see how I did it.

[sm=lol.gif]        You crack me up...I cant beleive you actually did it!!!!  And looks like it would work to.
 
Do yo think there could be any harm done to the carb in the long run? And where did you get the inflator at???

lol, yep, I did it!  [:D]
 
 
Since this is just nitrous that is being injected, it won't hurt the carb at all.  I picked up the inflator at a local bicycle shop for $20 (you can probably find them cheaper).  I then ordered a 5 pack of 16 gram nitrous cartridges from www.bestwhip.com for $10 after shipping. 
 
I'd like to see if 8 gram cartridges work because I can buy a case of them locally for $15.  They wouldn't last as long, but it would be even cheaper.

Those would be the 8 gram ones.

Hmmm...I think I might try this as a experiment on my little Honda...seems simple.  Thanks for the useful info.

One thing for you guys to kee in mind, I tested this out on a 250 cc motor.  Bigger motors will not see as big of a gain in power. 
 
Although, I am using a restrictor of sorts.  I imagine if I were to remove the restrictor it would do just as good on a larger motor. 
 
I'm going to go take more detailed pics and post them up.

Ok, due to popular request, here is a picture showing the break down of how I assembled the nitrous setup.
 

 
 
In order from bottom left, circulating around clockwise...........
 
bottom of inflator
nitrous cartridge
top of inflator
football/basketball/soccer ball inflator needle
hose adaptor (found at any autoparts store)
2' of 3/16" hose with a loop on the end, held in place with a zip tie
 
 
The nitrous cartridge goes inside the bottom of the inflator, then you screw the top of the inflator in to the bottom of the inflator.  There is a small pin that punctures the top of the nitrous cartridge when it is screwed in far enough.  The needle is screwed into the top of the inflator where you would typically screw the tire valve stem on to.  The plastic hose adaptor then pushes very snuggly over the needle.  On the other side of the needle, the 3/16" hose gets pushed on to it.
 
Now, you can run any size hose you want.  With a smaller size hose though, the nitrous will travel quicker through it thus giving you less of a lag time.  Speaking of lag time, as soon as I hit the nitrous on this setup I would start counting out loud.  I couldn't even get the full number one out of my mouth by the tim it would hit.  This is with the nitrous going through 2' of hose, then going through a 4' long 1 1/2" snorkel!!!  I would guess it has about a 1/2 second delay to it.

that is some ingenious n---- riged stuff right there. props on that 91cav.

I am gonna try this out, but I am gonna run the hose directly to my carb.

Ask me about 300trx gear reductions.

WTB/WTT:  9.9hp outboard, preferably merc, preferably electric start.

CAN YOU NOT RUN THE HOSE DIRECTLY TO THE INFLATOR OR WOULD THAT JUST DUMP ALL THE NITROUS OUT AT ONCE? I GUESS THAT IF YOU CAN'T THE NEEDLE MUST ACT AS SOME SORT OF REGULATER. YOU SAY THAT THESE NITROUS CARTRIDGES CAN BE PURCHASED AT WALMART? I THINK THIS IS AN AWESOME IDEA. I MIGHT JUST HAVE TO DO A DUAL OR TRIPLE STAGE SETUP. WHAT YA THINK ABOUT THAT? ALL THAT EXTRA PICKUP MIGHT MAKE ME...

You need to connect a hose tot eh inflator in some way.  If you don't, then there's going to be leaks in the system and it won't perform very good, if at all. 
 
You are right, I used the needle as a regulator of sorts.  With a larger orifice, you will get more flow, but it won't last as long. 
 
No, WalMart does not carry them.  They carry CO2 catridges but not nitrous cartridges.  You can buy the nitrous cartridges online (just do a search for "whip cream chargers"or go to www.bestwhip.com for the 16 gram cartridges) or you can find a local "smoke" shop (often refered to as a "head" shop) and buy 8 gram cartridges.
 
About 95% of all the nitrous cartridges out there are 8 gram ones.  The only place that I have found the 16 gram ones at is at the link above.  I do not know yet if the 8 gram cartridges will work in the typical inflator or not.  I will probably find out in a week or two.

be careful with the NOS.....when your running it your mixture of fuel and air will be real lean on fuel and may damage your piston. Keep a spare spark plug handy too.

1.  I always keep a spare spark plug with me just in case as well as all the tools to change it.
 
2.  I run 93 octane gas minimum when I do this.  Otherwise, 87 octane is fine.
 
3.  I don't continously spray, I only used it in very short bursts to keep the tires spinning in thick mud.
 
4.  I ran a VERY small shot of roughly 1 1/2 to 2 hp shot. 
 
 
Thanx for the feedback!!  I'm sure there are people out there who haven't thought about the issues that you brought up. 

2005 Suzuki Ozark, modded

I think as long as you only use it for short periods of time you wont hurt anything, at least that is what I am hoping!

Ask me about 300trx gear reductions.

we set it up on 4man450's foreman. just waiting on the nos. we did it different though. put the cartridge and holder under the seat and run a hose with a button to the handle bars.

Sweet!!  Post up and give us the results once it gets tested!!

nitrous works good. we had to spray it directly in the air box to notice. one tap raised the rpms by about 600.

That's good to hear!  Just make sure you're running high octane gas and/or jet it up a bit extra to make sure you don't run too lean and blow the motor.
