Whats the deal with NoS then lads, i know you can get two types wet and dry.

whats the difference between the two?

Will it work with carbs?

I imagine you use it in 3rd gear or higher, say just changed into third then hit the lil red button?

How much does it improve your times on the 1/4 mile (i know there are a lot of factors that come into play here but anyone with any spec engine got with and without times i'd be really interested)

What's the highest "brake" shot you can get or is it the more brake shot you have the more times you can use it before filling the bottle up?

Am i complete dumb a$$ with this stuff so lay mans term please fellas:thumb:

Wet kit injects fuel with the nitrous.

Dry just injects nitrous, leaving the standard system to do the fuel.

Use a wet kit.

Yes it will work with carbs

For 1/4 times etc etc it depends how much you use, and whether the clutch etc withstands the huge torque gain.

Oh, and its nitrous btw, nos is a brand name ;)

google is your friend ;)

In vehicle racing (http://en.wikipedia.org/wiki/Racing), nitrous oxide (often referred to as just "nitrous (http://en.wikipedia.org/wiki/Nitrous)" in this context to differ from the acronym NOS which is the brand Nitrous Oxide Systems) is sometimes injected into the intake manifold (or prior to the intake manifold), some systems directly inject right before the cylinder (direct port injection) to increase power. The gas itself is not flammable, but it delivers more oxygen (http://en.wikipedia.org/wiki/Oxygen) than atmospheric air by breaking down at elevated temperatures, allowing the engine to burn more fuel and air, resulting in more powerful combustion. Nitrous oxide is stored as a compressed liquid; the evaporation (http://en.wikipedia.org/wiki/Heat_of_vaporization) and expansion of liquid nitrous oxide in the intake manifold (http://en.wikipedia.org/wiki/Intake_manifold) causes a large drop in intake charge temperature, resulting in a denser charge, further allowing more air/fuel mixture to enter the cylinder. The lower temperature can also reduce detonation (http://en.wikipedia.org/wiki/Detonation_internal_combustion_engine).
The same technique was used during World War II (http://en.wikipedia.org/wiki/World_War_II) by Luftwaffe (http://en.wikipedia.org/wiki/Luftwaffe) aircraft with the GM 1 (http://en.wikipedia.org/wiki/GM_1) system to boost the power output of aircraft engines (http://en.wikipedia.org/wiki/Aircraft_engine). Originally meant to provide the Luftwaffe standard aircraft with superior high-altitude performance, technological considerations limited its use to extremely high altitudes. Accordingly, it was only used by specialized planes like high-altitude reconnaissance aircraft (http://en.wikipedia.org/wiki/Reconnaissance_aircraft), high-speed bombers (http://en.wikipedia.org/wiki/Schnellbomber) and high-altitude interceptors (http://en.wikipedia.org/wiki/Interceptor_aircraft).
One of the major problems of using nitrous oxide in a reciprocating engine is that it can produce enough power to damage or destroy the engine. Very large power increases are possible, and if the mechanical structure of the engine is not properly reinforced, the engine may be severely damaged or destroyed during this kind of operation.
It is very important with nitrous oxide augmentation of internal combustion engines (http://en.wikipedia.org/wiki/Internal_combustion_engine) to maintain proper operating temperatures and fuel levels to prevent preignition, or detonation (http://en.wikipedia.org/wiki/Detonation_internal_combustion_engine) (sometimes referred to as knocking (http://en.wikipedia.org/wiki/Engine_knocking) or pinging).

Ok Ok, anyone got times...with and without.

Cheers

Depends what engine you have to what gear yuo can use it in, I use it in 2nd gear upwards, any thing below a 2lt an I would be using it in every gear/

philsutton you sell off old kits cheap ? will be looking for a extra buzz once my new rebuild car as worn off
