This thread is about FI and the cylinder pressure involved, NA is a different animal. Regardless of HP I can't see a NA car producing the cylinder pressure of a boosted motor.

You're really just showing how limited your experience is with these posts. Think outside the box, instead of limiting yourself to what you commonly see on this board.

Is Nitrous still considered NA?

Read the OP; poster claims 300hp needs new rods/pistons no matter what, although this IS the FI forum

Yes. You're not forcing more air mass into the air, but the composition of that air is different.

Do you know the fundamentals of nitrous? Last time I checked it added cylinder pressure. Mike your reaching stop 300hp n/a that no one has scene add nitrous lol just stop

FI section, FI in the thread title

I think calling a nitrous car NA is a stretch

Please reread my first post, poster never claimed 300hp needs new rods/pistons no matter what. Stop twisting things
Your adding oxygen and condensing the cylinder charge so you packs more air in so yes you are forcing air in. Come on man really...
I would love to see a 150 shot of nitrous hit that little 2.0 on a stock bottom end it would be epic 1 time....and I seriously doubt it would make 300 and live

There is more to in-cylinder pressure than boost.

So many tuners desperately try to hit MBT in controlled environments, and then have their customers pop the motors when conditions deteriorate in the real world.

Allowing more oxygen in, not forcing more mass of air in. Your MAF and MAP will read identically.

The air is still being sucked in by the engine, not being shoved in or being compressed.

in·duc·tion
inˈdəkSH(ə)n/
noun
noun: induction

the stage of the working cycle of an internal combustion engine in which the fuel mixture is drawn into the cylinders.

Soooooo somebody gonna show this NA 300hp frs or naw?

This sounds like a summary of tuning in general, any setup

A nitrous bottle operates at about 1000psi, is that not "shoving in"

That is a good point but its adding a new fuel source rather then compresed air right??

Edelbrock Performance Nitrous Systems Support



HOW DOES NITROUS OXIDE WORK?
As stated before, nitrous oxide is an oxidizer. An oxidizer supports combustion by supplying additional oxygen. Initially, the nitrous doesn't help the process. This is because as long as the one oxygen molecule is bonded to the two nitrogen molecules, the oxygen isn't free to aid combustion at all. Only after they've been exposed to the heat of the combustion process will the chemical bond be broken (the bond breaks around 570 degrees), allowing the free oxygen molecule to then contribute to the combustion process. Additional fuel is added along with the nitrous to maintain a stoichiometric air/fuel ratio. The end result is more horsepower being created pretty much the same way a blower or turbocharger does.

Depends how you look at it, wet or dry kit. Nitrous is 33% oxygen which is really the goal here no matter what we are talking.

Dry vs wet, why nitrous also has nitrogen is another discussion (absorbs heat, stability)
