everyone KNOWS turbo equals added fuel demand... and turbo ALSO forces air into the motor...

well a dry nitrous kit DOES add extra fuel to compensate, BUT it adds it through the stock fuel lines, rail, and injectors... the injectors unless upgraded are already being taxed on boost.. so now you are going to spray on top of that and push them even more, in a lot of cases TOO far.. till they fail.. and you detonate..

the OTHER problem is this.. when forcing air into the intake path of a car AND you add a dry nitrous kit you are now doing even mor epotential damage.. the dry nitrous is now being force fed into the motor, and being PUSHED to the back cylinder this is causing uneven nitrous distribution, and since its a DRY kit the fuel is being added equally to EACH cylinder through the injectors, thus causing the last cylinder to lean out... like this..

you spray...
the fuel pressure rises (thats how dry kits work)
the increased fuel is EVENLY distributed to each cylinder
the nitrous is THROWN to the back cylinder by the force of the turbo
the last cylinder runs hot and lean..
thats the deal..

this does not happen with a wet kit because a wet kit does not use the stock fuel system...
it sprays gas and nitrous.. and the cars fuel pressure stays the same
so it is still unevenly distributed BUT so is the gas so it compensates preventing serious detonation

its easy to sit here and say dry nitrous is stupid, but id rather try to explain it for you...

i hope you guys spraying dry and turbo have invested in some real nice fuel pumps and injectors.. because if not... i can't see the stock shit holding too long..

hope that helps you understand better

if your saying that the turbo is going to force the nitrous into the far cylinder then why isnt the plain air being forced into the far cylinder? which would also result in uneven air/fuel across the cylinders.

also i've heard quite a few bad things about wet kits and Hondas because the IM cant flow the fuel correctly, so the nitrous goes evenly to the cylinders but the fuel doesnt.

maybe that guy did have upgraded injectors/fuelpump.
