Nitrous Oxide Injection (NOS)

Unlike conventional tuning, or Turbo's & Supercharging, Nitrous Oxide Injection is only a "short term" hit,  In that the bottle of Nitrous Oxide will run out sooner or later!

Nitrous can however give a much BIGGER boost in power than other forms of tuning.  Not only that but it can be used on otherwise stock cars.  When correctly set up on any road car there will be no engine wear penalty and it is completely safe.  Typically different types of tuning give at best the following approx power increases:  Other advantage is that once switched off, the cars is completely original.  No bad idle, no fuel economy losses or emission changes, and it will be as smooth and quiet as a stock vehicle should be.

Conventional tuning  - 15 to 80% power improvement.  Typical = 25%  Cost = High, Drivability = worse than stock.

Turbocharging - Up to 100/150 % power increase is possible.  Typical 35 to 60% on road cars.  Cost = High,  Drivability = good but some turbo lag inevitable, increasing with performance per cc.

Supercharging - Up to 100 / 150% possible. Typical on road cars = 40%. Cost High,  drivability = excellent, no lag.  Fuel economy less good due to power sapping supercharger driven by engine.

Nitrous Oxide Injection - Up to 600 percent power increase possible!  Typical on road car 50 to 100% increase peak, but much higher at lower RPMs.  Short term use only until bottle runs out...  Cost medium, but same system can be moved to all future cars later on.  Does not "wear out" and not vehicle specific unlike cams, heads, etc.  No lag.   Can be used with a turbo to eliminate turbo lag!

Here is an example of a simple single stage nitrous system on a standard motorcycle.  This shows 2 runs (power x RPM).  This was a single stage operated from a button as the engine reached 7,400rpm on the dyno.  It speaks for itself!  Click for more detail

Same run, but showing HUGE torque increase!!!  This was my own bike.  It was running on my own Dynamometer system
