me and my bud have a little one seater cart we bought online. it breaksdown all the time and we dont really like it. weve takin the gov. off the 2 motors we have and it runs on pretty good. since we have 2 and a fully equipped shop and some good mechanical knowledge w wanna try somthing. My friend has one of the big full nitrous bottle that he cant use. how can we get it into the carb???? i was thinking putting a small nozel in the small hole for the valvecover breather. will that work???? Do i have to buy stainless steel line or can i use some good ruber hose??? it doesnt have to hand full bottle pressure just enought to give it a little boost. i dont think a little 5hp briggs is gonna stay together under a full shot. since we have 2 motors and a lot of parts we dont care if we blow it up. just bord looking for an afternoon project.

One problem, when it gets that shot of nitrous its gonna go way lean and BOOM. Why not get out a dremel tool and port the head, if you can have it milled down for more compression or use silicone for a head gasket, then buy one of those cams online. See if you can give the sucker some OOMMPH and dont forget to give it a straight pipe. If you wanna use the nitrous, jet that sucker way way way rich on the top end, lean or normal in the mid and bottom then do a shot straight into the carb with a fogger right inside the engine side venturi or between the motor and carb on that little runner thing it has for an intake manifold. Only bring it on at full throttle.DISCLAIMER I KNOW NOTHING ABOUT NITROUS EXCEPT WHAT I PICKED UP FROM HOTROD TV SO DONT HOLD ME TO IT lol.


P.S. dont forget to gear it higher cause its gonna haul **** and you wanna have the gearing to use it.

 

<< My friend has one of the big full nitrous bottle that he cant use. >>



Then why are u asking about using it on a gocart if he cant use it.

I also hope you realize that the NOS isnt a combustable fuel and sticking it in the breather isnt going to do jack. You would have to get a real Nx kit from Nitrous Express for it to have any sucessful runs. They retail for about 399-499 (cant remember how much it is exactly). But they do make them expecially for go carts and go peds. Check out NitrousExpress.com and read the FAQ. It will teach you alot. NOS tanks run at an EXTREMELY high Psi, so I wouldnt even bother with anything less than 1000psi hose. If I were you, learn a bit about porting and get yourself an alky carb conversion for it too. Mill the head for higher compression and like Jakal said, get a strait pipe. Then you might be talking..

U dont get it. he doesnt have anycars he wants it on so we want somthing to do with it. i have a nozel why cant i spray it in the carb???? thats how the real system works. Anbody know were i can pick up a regulator thats ajustable??? anybody with a better idea on how to get it in the motor would be nice. i wanna run a nozzel in thru a already made hole and have it so it intakes the nos with the fuel. Nick i know that nos is a combustable fuel its just an accelerant that makes it burn faster. i just wanna know what i need to hook it up. and can sumbody come up with a type of jet im gonna need?????


Thanks Ryan

 

This is directly from the NitrousExpress Webpage..

Q. How does a nitrous system operate on a carbureted vehicle?
A. The most common method of boosting power on carbureted applications is the use of a &quot;plate&quot; sandwiched between the carb and the intake manifold. This plate contains orificed tubes that deliver the nitrous/fuel mixture in precise ratios.

Id like to see you shove the NOS nozzle in the breather. See what happens. Its really not worth the time and effort to hook it all up just to have it hurt the engine in the end.

I can see how you could call NOS an accelerant, but it technically isnt. All NOS does is provide the engine with MORE oxygen inside of the combustion chamber to burn more fuel. Burning more fuel = better efficiancy and more speed.

 

Lets put it this way, NO2 is nitrogen with two oxygens stuck to it. Nitrogen makes up 70% of out atmosphere and does absoltely jack. When the NO2 has more oxygen than nitrogen, therefore its super air. Oxygen is the only thing in air that burns. In other words a turbo shoves more atmosphere in there, but its 70% nitrogen. Thats an option you get more oxygen but you get other crap in too. NO2 skips putting the other crap in and loads it up with lots and lots of oxygen and lil nitrogen. Not to mention its cold and super dense. Imagine it as a super turbo that removes the most of the extra stuff, then super chills it to get even more in. What do you need with all this new Oxygen? Fuel!!!!. I have no idea how you work it with a carburator but i think some systems fog gas in too (wet system?). Have to have that sucker tuned. Fuel injection sensors handle the problem for you in modern cars. So its just not as easy as adding the NOS you also need more gas, lots more gas. Figure that out and figure out what the proper ratio is at what preassure and then youll be alright. Then get a spare piston rod crank and head ready for when that one flys 10 foot in the air.


Sorry if im down on my hot rod terms, dont have cable tv no more so no more Hot Rod tv. The theroy is simple chemistry though.

 

all they use on carz wit carbs is a basplate with a nozel in it. the more i talk about it the more i question my idea, subody said that some motor parts might look nice in the back of my head when she grenades. i dunno im still gonna look.

go get some of that moddle car fuel from the hobby shop. zzzooooooooommm!!!

 

Nah, last time i tried a small engine with nitro meth the carb didnt like it. Besides nitro methanol is way to potent, in top fuel dragsters they start them on normal gas because the nitro meth would throw it apart. As for it blowing up, well, probably so. These things just arent built too tuff, ive seen one throw a rod from reving with not enough load. So seems to me that the rod and rod bearings just plain suck, do they even have rod bearings? I dunno though, my old tecumseh 5.5 sport had the air box covered in holes and a home made ram air kit. Not to mention i put a straight pipe on it. Used to rev like crazy all the time and it never flew apart after about 3 years of it. It was OHV though.

Give up on the nitrous, if you really want to have fun find an old monster chainsaw engine, rebuild it, have some engine shop do a port job. Use a junker dirtbike pipe from an engine of the around the same size. If you can get ahold of it get it a light weight piston. Now you can rev into the stratosphere and haul some serious ****. Most big chain saw engines already have a good bit of power anyhoo, after that porting all the fun starts. Heck if you want get an alcy carb. Consider is a bad **** dirt bike engine that was real cheap. You dont even want to know how much you can make one of these things rev.

Hehe, found two bad chainsaws on ebay, one with like 101ccs and 7.5 hp, the other was real old monster one with 250cc, hp not stated
