The principle difference between dry and wet Nitrous
injection is that with the "wet" kind you injected additional fuel along with
the nitrous input into the air intake. So the manifold is "wet" with
fuel. With "dry" concept, you pour the nitrous oxide through
the normal air intake and increased the fuel through the normal fuel injectors
by extending injector PW during the Nox injection or turning on additional
injectors. Since with this approach the intake does not have fuel squirted
(except through the normal injector ports) the manifold remains
"dry.
Variations abound but this is the basic conceptual
difference between the two. Some claim you need a mass flow sensor
to do the "Dry" approach, but that is not really correct, you just need some
means of sensing the onset of Nox flow and increasing the fuel flow to
match.
I was interested, but after seeing what nitrous oxide can
do (see photo of auto that had a bottle in its trunk), I lost interest

Subject: [FlyRotary] Re: Carlos' theory
on Nitros
About the only thing I would consider it for is for a quick boost on an
amphib to get off the water or challenging Bruce Bohannon to a climb
contest.
Carlos was explaining the difference between wet & dry nitrous
injection which I still don't feel like I understand well enough to explain
myself.
I was trying to explain an idea I had for using the EC2 to deliver the
extra fuel required (via the EFI injectors) when injecting NOX instead of
using a separate gasoline injection port. Not sure I explained it well
enough for Carlos. It might not even be a good idea. Goofs
on laughing gas tend to be expensive.
