on Nitros
I have been flying for 1400 with nitrous
and its the only way I can get the coot out of the water, I use it for about a
5 second burst to get it up on the step and may give a longer burst if I need
to get out of rough water or out a tight spot, also use it to get a heavy load
out of a short runway.
Good explanation on wet and dry, I use the wet
system made by NOS.
Yes Bruce used it for the time to climb and
also Pushy Galore used it to set a altitude record of 32,000 ft with a 0-200,
they used 10 lbs at a rate of 1 lb per minute, actually made it to 34.000 ft
but when the nitrous ran out the plane stalled and he dropped to 32,00 ft to
hold level flight to set the record.
As for that blown up trunk there is no way that
nitrous did it alone as its just an oxidizer and is no more dangerous than the
oxygen bottle next to you for breathing, I suspect he may have had a leaky gas
can in that trunk with it on a hot day and the blow off disk blew off and
mixed with the gas to cause the explosion.

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 {:>)

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.

Tracy,
I walked up on a conversation between you and
Carlos. Ya'll were
discussing Nitros in our applications. Can you
give us a synopsis of
the conversation. I picked up just enough to
tell he was not for it.
Please
explain!!!
Bob
