DrMayf, please except this response as simply coming from somebody who
uses the stuff, and does not claim to be the magna-fluid/thermal engineer.
To my limited knowledge base, the induced charge is simply more oxygen rich
thanks to the nitrous. In other words the induced column of air and fuel, runs
into
and picks up and or is drug into the nitrous/fuel mixture. I am told that on a
port
type system the port velocity actually does increase with the nitrous on, with
nozzles
injecting at 90 degrees to the port wall, even with the nitrous expansion in the
port.
Dont have a flow bench handy to prove it.
As to the column of air fuel mix that eminates from the port away from the
valve,
as I am told during dyno testing is very impressive, on say a motorcycle
cylinder
head
with individual cylinder induction systems, and surely this column is full of
nitrous as well, and
I must assume contributes to airbox explosions on bikes, that has plagued many
the
past few seasons in drag racing.
I am sure Dahlgren, who gets to dyno many nifty motors can shed some light.
Joe :)
