\Now, I've been thinking about Nitrous Oxide lately in the road scene...50 shots here 100shots there, yeah, big horsepower gains.

Nitrous works by adding a volatile combustible gas to the combustion chamber to allow the combusting fuel to move from a liquid to gas state easier and more efficiently....you're not "Burning" the nitrous...you're enhancing your air or fuel supply with it.

Now, large dry shots are dangerous, cause your oxygen sensor sees a leaner mixture and compensates with more fuel which results in more power or...explosion.

A wet shot is preferred because you're taking a gas, which is under pressure and therefore a liquid, adding it to the fuel supply, and blowing the shit through your injectors. Therefore you can achieve a better blend of your nitrous, fuel, and air! Which means? Mmm...power. Cause even motors like things wet and lubricated.

Anywho, moving on

What if, instead of large shots of nitrous, using a computerized system to automatically shoot nitrous into your motor depending on what it reads from your car's onboard computer.
Say, this program measures the amount of fuel the engine is using, the RPM's the engine is running at, the rate of acceleration, the gear you're in, the amount of oxygen the engine is using, and of course, how fast you're going and add's nitrous accordingly for circuit use, jsut like the ECU does with your fuel supply.

On the circuit a 50 shot of nitrous used at a strategic point is nice and effective, but what if, say I'm coming into a corner under Natural Aspiration, brake, make it through the corner, but i've lost speed.
You're normal car would require track length to gain that speed back...and maybe there's another corner before then.
Why not aid your car in regaining that speed with small intermittent shots of nitrous.

Say your car is leaving the corner, and the program reads that from just a second ago, you've registered a 30mph decrease in speed, an RPM jump of 3K from where you've downshifted into or out of the corner, your engine is burning more fuel, and sucking more air just to accelerate...so it adds nitrous to the mix. Depending on how hard your car is working is how much nitrous it adds. If you're at 4.5K RPM and you redline at 6K...it won't shoot as hard as it would if you were lugging out of a corner.

So basically, it's a need based computerized shot of nitrous. If you're sitting a dead stop, the computer reads you are not moving and shoots a predetermined shot of nitrous.
The driver would be able to Tell the program about his/her requirements. If he/she wanted a 50 shot of nitrous every time the car was at rest and was launched the program would respond.

Say the program would have a 500 mile "learning" period. it adjusts to YOUR car and knows it's speeds, shift points, your driving style, blah blah...much like a lot of turbo oriented programs, but instead would use this to adjust for nitrous shot. So if you come into a corner wrong, and mis calculated, lose a lot of speed, the program would compensate by adding to your car the extra 20 horsepower required to accelerate back to track speeds.

OR you could put the car on a trickle system, where it blows a 10+ dry shot into the intake...now we are saying, what about the o2 sensor? What about Mass airflow?

Nitrous blown into the intake system does three things.
1. It adds a volatile combustible gas to your air induction...now your incoming air is combustible!!
2. Nitrous is a compound substance. Meaning it's made up of two or more substances for those who don't remember high school chemistry. This means when it combusts, the nitrogen and oxygen separate, the fuel explodes, the nitrogen is discharged, and the oxygen is stolen to combine with the fuel's bi products. So adding Nitrous is adding oxygen to your intake...which is already drawing oxygen
3. Last but probably most important for my method of dry shooting....a dry shot of nitrous will drastically drop the air temperature as the liquid nitrous changes from liquid to gas, resulting in denser air flow.

Won't the o2 senser read this denser air flow and send more fuel? YES!!!!!
So now you're adding a dry, cold, combustible substance to your intake, but how much? You're not looking for huge HP numbers...you're looking for track efficiency and reliability...you dont' wanna be pushing a 50 shot for 9 laps and blow up your engine before the finish line. So, you add 10+ shot throughout the race. What's this DRY 10+ shot doing?
1. It's a substance containing nitrogen...which removes moisture from the air...motors don't like moisture in the air.
2. Dropping the air temperature. Meaning denser air, meaning more fuel = MORE N/A HORSEPOWER
3. It's Nitrous Big smile

So essentially you're taking small amounts of nitrous to drastically BOOST your compression ratio. So if you're running a N/A engine, you can push larger power numbers, run with the turbo guys, and keep your nice clean and efficient compression ratio

Turbos are fun, but in my opinion very wasteful.
What happens when running turbos? Usually you lose overall compression for a compressed air supply. Why? High compression and turbos don't mix. Anything over a 9.5:1 ratio and you're asking for your engine to explode, which is why turbo guys will build their heads to "handle boost" ...basically they are opening the heads up to increase air and fuel supply, but drop the compression.

My nitrous idea doesn't do this. It's a bolt on alternative to turbo, for similar overall gains, no lag, immediate power, the ability to still shoot that 100 shot at the touch of a button, and never have to drop your compression to run a turbo.
Instead you can actually up your compression to that nice peppy 11:1 or 12:1 ratio and purge next to the turbo guy at the light, only to waste his wastegate!

It already exists , its called a programmable nitrous controller. You can dial in the the amount of N2o based on throttle position.  A normal 10lbs bottle wouldnt last long even at a trickle and N20 aint cheap.
