  Testimonial:
A quick story, Big Red (CR500) was already fast about 65HP to the rear wheel with the engine mods, but with these NOS shots I ran the Back Side Sand Mountain all the way to the top in 5th gear! Before that I would have to shift down to 4th about 60% up or run it in 4th depending on the Sand conditions. 
 
I also raced the Face where the High Dollar Boys play and speed wise I kept up (with all but the 100 mph machines)
 
Again, thank you!

Nitrous Explained

Nitrous oxide attacks the problem of how to get more oxygen into the cylinder from a different angle, don’t change the amount of air the engine can breathe by forcing air in like a Turbo or Supercharger, but increase the amount of oxygen it can breathe. Air contains only about 20% oxygen, where nitrous oxide contains about 36% oxygen. If you add nitrous oxide, you increase the total mixture’s oxygen level significantly, which allows for up to a 50% increase in oxygen level.  That's a huge increase in POWER. The nozzle mounts on the air box or air filter where it sprays a fine mist of nitrous that is then drawn into the engine through the carburetor. This allows the nitrous to be naturally aspirated into the cylinder instead of being forced, which is much friendlier to the motor and allows the nitrous to be used in a much wider range of throttle and rpm settings.

An interesting side effect of using nitrous oxide is the cooling effect it has on intake temperatures. When released from 6 Sigma's pressurized container, nitrous oxide temperature drops to around negative 129 degrees, which will cool the overall intake charge by up to 75 degrees, resulting in even more horsepower. When it is installed before the carb, the denser air flows through the venturi faster, creating a larger pressure differential in the venturi. This larger pressure differential draws in more fuel from the Bernoulli effect.

The big advantage of nitrous is that it provides power on demand at the touch of a button. Otherwise, you don't even notice it's there.  

 

Boost Bottle Explained

It's function is to absorb & release pressure pulses within the intake vein, assisting engine breathing of a 2 stroke engine. During the intake stroke, air is sucked through the intake manifold and into the port at a considerable velocity. Because of this velocity with the air's mass, it  has inertia. When the intake port closes, the kinetically charged air suddenly has nowhere to go, creating a high-pressure area. Naturally, the air wants to release its pressure in the easiest way possible, so it tries to shoot back out the way it came, creating a pressure wave in the opposite direction of the intake direction. Then no sooner does the wave begin to travel, the intake port suddenly opens again leaving the motor to try and pull the pressure wave back in again. This dramatically effects the lower RPM power band, wastes energy, and kills low-end performance.

Now with a BOOST BOTTLE, Air goes down the manifold until the intake port closes. The air, still all charged up with energy tries to escape back up the manifold but is met with a small port that has a residual vacuum. This vacuum being caused by the previous suction of the intake stroke, sucks most of the pulse inside the Boost Bottle, storing much of the pulse's energy. The intake valve then suddenly opens, creating a low-pressure area outside of the Boost Bottle. The gasses then shoot out of the Boost Bottle, directly into the intake system as a pressure pulse, instead of having to be pulled in by the piston. More air is then also pulled in from the manifold to completely fill the cylinder… Thus giving you an additional boost of power. These have been Dyno tested and proven to work, they show more hp increase on the low end,  some hp increase at mid rpm, and a little hp increase on top end. Boost bottles work best in conditions where a rider is constantly going from full throttle, to closed throttle, then back to full. like on a motocross track, or very small tight road course.

Want to tell you how well your little nos shot worked. set up exactly how its sent, picked me up 2tenths of a second. i was hitt'n it right off the launch. the bottles can get three passes...  i know that because i won my class with it

Nitrous Oxide (NOS) is the simplest, least expensive way, to provide a significant horsepower boost to your engine, and add performance you can feel in the seat.


Nitrous Benefits (2 & 4 stroke engines)

• More Peak Horsepower

          Designed to gain 20% in Horsepower at Wide Open Throttle

• More Low End Torque

           Torque gains are even greater as there is an increased combustion at a lower rpm range and causes the significant improvement in acceleration.

• Low Cost, High Performance

           Nitrous offers you more performance per dollar spent, than any other performance modification. 

• Easily Transferable

           Nitrous Kits can easily be removed or transferred to another vehicle unlike conventional tuning parts, such as exhausts and intakes.

• Easy Installation

           6 Sigma N20 installations are very easy, literally only taking a few minutes with basic hand tools to install. No wiring needed.

• Fuel Mileage and Drivability

          Since 6 Sigma N20 is used only when needed, it offers you the advantages of complete drivability and normal fuel mileage while not "on the button."  In fact, nitrous works best with motors that are stock or mildly modified.

Boost Bottle Benefits (for 2 strokes only)

• More Low End Power

          Designed to gain Power at lower RPMs

• No Maintenance Performance

           You do not need to refill the boost bottle as their sole purpose is to even out your fuel mix and apply the right amount of pressure to take your pre-atomized fuel and dump it into your cylinder when you are on and off the throttle. Once your boost bottle is mounted on your engine, please do not remove it. It will outlast the life of your engine and only operate better. It does not need to be refilled.

FAQ'S
Q: Can I simply bolt a 6 Sigma N20 kit onto my stock engine? 
A: Yes. In fact Stock engines are often best!

Q: Do you ship international, and how much?
A: Yes, we ship worldwide, for $19.42. Make sure it is legal in your country.

Q: How much performance improvement can I expect with a nitrous system? 
A: Depends on how you set it. You simply choose!

Q: How long can I hold the Nitrous button down? 
A: It depends on how large of a shot you are giving the engine, but typically 3 passes.

Q: When is the best time to use nitrous? 
A: At wide open throttle. 

Q: Can I install this kit?
A: Yes, you can install it, don't be intimidated if you've never done this before, only very basic skills are needed, and it has instructions with full support. 

Q: How long does it take to install?
A: A few minutes, up to an hour, depending on your skill level.

Q: Does this kit come with everything I need?
A: Yes, it is a comprehensive performance upgrade kit. 
 
Q: Will this nitrous kit work on my Fuel Injected or Carbureted Engine?                             A: Works on both carbureted and fuel injected engines 

Q: Where can I get more NOS bottles? 
A: We sell them

Q: What effect does nitrous have on an engine with considerable miles on it?

 A: Mileage is not an indication of engine condition.  Worn engines may be a problem, high mileage will not be. 


Q: What are the advantages of using nitrous compared to other performance options? 
A: The cost of many other performance options can put you in the poorhouse. You can't buy more performance with less money than nitrous. With a 6 Sigma Nitrous System, performance and reliability can be had for a much more reasonable price while retaining the advantages of a stock engine during normal driving. And, nitrous offers tremendous gains in torque without having to rev the engine to excessive rpm's. These factors help your engine last longer than many other methods of boosting horsepower. 

The Flow Shot Size jet is also included. (Not in pic) This restricts the flow of the Nitrous to produce the correct sized shot for your engine.
