The way to understand the principle is as follows;
1) As things stand, at some level of nitrous injection airflow IN TO THE ENGINE COMES TO A STOP and beyond that point, nitrous flows OUT OF THE INDUCTION SYSTEM ALONG WITH ANY AIR THAT MIGHT HAVE MADE IT'S WAY IN during any drop in manifold pressure.
2) This phenomena becomes the limiting factor in how much power the engine can make.
3) By shutting off the INDUCTION SYSTEM AT THIS POINT we are NOT shutting off the air flow, because that has already happened.
4) What we are doing, is preventing what would normally escape from doing so and should result in any additional nitrous that is supplied to the induction system, to be made available to the engine on the induction cycle, that would not otherwise be possible.
5) The device/system that I have designed will ONLY come in to operation when there is a loss of negative manifold pressure, therefore no loss in performance will occur as there will be no loss in airflow that would not already be lost in the operation of a conventional nitrous system.
6) Under these conditions I anticipate that it will be possible to supply adequate nitrous to achieve an increase in performance over and above that achieved by a conventional nitrous system, rathyer than it being wasted by blowing out of the intake.
They're the points i did get a grasp of.... What i'm getting at is that at points 4 and 5, should you be using lots of nitrous, is there a danger that after the induction event has occurred that there is still positive pressure in the inlet tract, and you then become a sealed nitrous only system??
I appreciate that at lower pressures this will result in a more efficient use of the nitrous, which im all for. Guess where i tripped meself up was taking it as looking to get more air than NA as opposed to more air than normally associated with that quantity of nitrous.
