You could google it or wikepedia so you can feel the shame and discomfort of humiliation in private.

 

Why are you asking me, I'm the moron remember?

 

AHAH ok... i figured you could get the sarcasm in my post.... i was laying it on pretty thick there...

 

Doesn't nitrous just help the fuel burn by breaking into it constituent atoms (Nitrogen and two Oxygens) as it enters the cylinder and is exposed to high temps ?

I doubt it could be considered FI since it really isn't actually compressing anything, despite being supplied in compressed form, it really is just an accelerant.

Now, having said that I could be wrong, I don't want to get into this pissing contest, just wanted to put forth my take on N2O

 

we all know how it gets to the engine... ITs forced there through pressure. what happens when your bottle gets low or empty? NO pressure to sustain proper flow and no power... Therefore its clear that its forced induction. Just as if a turbo didnt spool or the S/C wasnt spinning, you wouldnt get the extra power.

 

You tell this story however you want to hear it.

Simon, you are dead on.

 

again... typical that youre totally changing the discussion.... AGAIN!... this is totally pointless. Either way, i guess i cant win... If i had NOS, then it wouldnt be considered a bolt on, but i still couldnt beat a 997S.... or if I dont have NOS, i have no chance of beating a stock 997S. Seriously.... wow. thats all i can say. You want to argue the semantics of the term "forced induction" but in the grand scheme of things it doesnt relate to the core of this discussion at all.

 

youre right, it doesnt compress anything... it uses decompression to force gas into the motor. In a wet kit, it uses a fuel line and a gas line to INCREASE the volume of combustible elements to make more power... thats exactly what a turbo or s/c does.

 

What? You have NOS? Yeah, I honestly don't know how effective it is in an E46 M3 but my guess is that yes it would be enough. Do you have it or no?

Is that the gizmo?

If you do have it, you ought to know it is not considered FI even if its funny to strangers in a chat room.

 

I think this is a weak argument, under these rules one could call your fuel system forced induction too since it's pressurized by a pump and forced through the injectors into the cylinder, but clearly this is not the case.

I think FI normally refers to the actual air charge being compressed (and cooled) before getting to the cylinder and mixed with fuel, although that is my (fairly simplistic) view of what the term "forced induction" means.

I'd be happy to be proven wrong though, always happy to learn something new.

 

no. i do not have NOS on my m3. And yes, it is very VERY effective on making power on the s54. as far as my argument goes: turbo and S/C increase air volume through compression and increase fuel through tuning and injectors. NOS increases air volume through decompression of the bottle and increase fuel through the injectors and added fuel line if running a wet kit. SAME main goal: increase combustible air volume and fuel volume for more power. How is it faulty logic to consider NOS as a source of FI?

 

i have an M3 with boltons N/A light weight (500LB weigh reduction) i had no problems racings 997s and beating them. ( i own both cars so i really dont need to prefer one car over the other)
its very simple M3 stock makes 343hp and with boltons N/A around 380hp+ ( Air box CF (CSL), ecu, Full exhaust system and further reducing its weight to around 3000lb, it will make out perform a 997s making 355hp since it will be making more power than the 997s with less weight.
A stock M3 with an ECU upgrade alone would probably have no chance ( i agree with that )
But comparing it to an M6 or E60 M5 is a joke.

 

Super chargers and turbos are basically pumps that physically force/compress a larger amount of air into the cylinders to increase power. Nitrous when introduced to the air in the manifold interacts with the atmospheric air and oxidizes it and the evaporation of the liquid nitrous cools and condenses the fuel/air charge which results in more effecient combustion.

 

500 is a LOT of weight....


gizmo is a metal screen replacement in formt of the mass air sensor...good for 3 hp..

 

500pounds is a SIGNIFICANT weight savings.... that car must be REALLY fast. Sounds like a very awesome vehicle to have. Thanks for adding in your experience!
