NOS DirectPort Injection: How direct port nitrous oxide injection works


an NOS direct port system is
easily identified by noticing multiple foggers one intended for each individual intake
runner each nozzle will accept fuel and nitrous Jets and
the appropriate feed line connections when the system is activated additional
fuel and nitrous will be introduced just prior to each cylinder because each cylinder has
its own nozzle this method of delivery allows for
higher increases in power and accuracy when compared to other nitrous systems
but is also a more complicated system to setup multiport fogger systems can be used on
carbureted or fuel injected engines however single plane intake manifold are
preferred for carburetor applications for fuel
injected engines plastic or other non-metal intakes are
not recommended for multiport fittings the alternate and
preferred method for adding fuel is to install a second fuel cell
and use a second fuel pump to feed fuel to the solenoids additional
fuel is combined with the additional air from
the nitrous and much more power can be created in the cylinders

  1. Why is a 2nd fuel pump recommended? Why can't you just tee- into your existing fuel system (assuming you have enough flow volume/pressure) ?

  2. Nitrous is ok on certain builds but with modern turbo and supercharger technology and tuning, you don't really need all the extra hassle of running a nitrous system when a larger turbo or blower would do the same thing and give you consistent power. Though, it is good to help spool large turbos or add a blast of power to help pull through gears, you just have to refill the bottle a lot and keep it heated for proper use.
