All motor, baby!
BTW, that's all motor with a shot of nitrous.

Was that 9 seconds on ALL MOTOR? If not then it was the fastest KA24DE-T, while this is the fastest KA24DE. There's a little more to the story here.
The car is not TropicalJewel's, nor is it mine. I've never even met the guy, while TropicalJewel has. I know it's a blazing fast non-turbo S13, though.

Nitrous is not all motor. Nitrous is forced induction.
Unless he wasnt spraying on that run because is says in the forum he leaves it in 11s for bracket racing and puts it in 9 second trim for import events. So i assume nitrous is used to run 9s but thats a big jump from 11s to 9s. Still a sick car, no matter how you look at it.

It's not shoving more air into the engine... the engine is still naturally inducted because there is no positive manifold pressure.
Nitrous is a power adder, not forced induction.

NITROUS IS NOT FORCED INDUCTION.
Forced induction is where compressed air causes pressure above an atmospheric rate in the intake manifold. The nitrous is ingested naturally through an intake tract. BY saying its forced induction, you also say that alky injection is forced induction as well. I suppose ram air is forced induction? no--power adder--yes. forced induction, absolutely not. Oxygen content Desnt have anything to do with how nitrous or any other foreign prporty is introduced into an intake tract, nitrous is breathed in just as the air around the filter. if you open a bottle of nitrous above a filter element, and rev the motor--what happens? does the nitrous get forced in? nope--it gets sucked in. forced induction---higher induction rates as a result of boosted atmospheric condition(above 14.7) in the intake manifold. Next time you see someone spray --if they have a turbo and a boost gauge--check their boost gauge--youll rarely see an increase, and if you do--is because of the efficiency increase cuased by lower temps that occured when they sprayed.

i totally agree, if you are talking about a dry system. imo a wet system is a power adder, not forced induction. dry and direct port use force to enter the engine, while wet systems just add nitrous to the gasoline.Exar-Kun wrote:nitrous has a higher oxygen content than atmospheric air, and its being forced into the engines intake tract..thusly, its a form of forced induction.-chet
" suppose ram air is forced induction?"
no its not, it's not shoving more oxygen than is natural, or presurizing air into the intake tract. this isnt hard to figure out. and by typing in caps, it doesnt make you right. alchohol injection or meth engines are a completely different ball gamelets keep this to gasoline powered engines, shall we?
"if you open a bottle of nitrous above a filter element, and rev the motor--what happens? does the nitrous get forced in? nope--it gets sucked in"
yep, thats true, but n20 contains a far higher ammount of oxygen than is in the air you breathe, and I dont think either of us are talking about running a car in a room full of n20, are we? Nitrous uses JETS to push a abnormally(in regards to normal ambient air) high oxygen content gas into the engine, making, depending on the "shot" of nitrous, a cetrain percentage higher oxygen level than would normally be present in the system...wet systems just add extra fuel to compensate for this...
now, a turbo or supercharger generates additional oxygen into the intake chamber by compressing ambient air using either a belt-driven compressor or a exhaust gas driven one,
in all 3 methods, the O2 level in the manifold will be much higher than without the systems, even on an unrestricted engine. thusly, they are "forcing" oxygen into the engine that is not there..
forced induction.
"if they have a turbo and a boost gauge--check their boost gauge--youll rarely see an increase, and if you do--is because of the efficiency increase cuased by lower temps that occured when they sprayed."
duh. nitrous is a great oxidiser and generates lower intake temps. that can lead to an icnrease in turbo efficiency, sure...but it's still a form of forced induction.as to this point:"The nitrous is ingested naturally through an intake tract."I dont see how using a pressurized jet or compressed gas system to deliever something not found otherwise into a intake tract is natural....then again so the compressed air from a turbo is 'ingested' through the intake manifold, albeit at higher pressures.... the point I'm making is that the oxygen content of the n20 isnt "supposed" to be there, more 02=more combustable material for the engine, same as compressing ambient air to shove more oxygen into the chamber.
n20 is forced induction, for all intents and purposes...you';re engine burns oxygen, the gasoline simply allows the chamber to iginite the oxygen, and gets burned in the process.

no, but thanks for trying!!
the term "wet" is used to describe a nitrous system that also injects fuel along with the N2O.
IT DOES NOT ADD NITROUS TO THE FUEL!! i dont know what crackhead told you that.
it just sprays fuel AND nitrous. the mix is tuned so that there is fuel injected along with the nitrous to equal the amount of oxygen released when the N2O breaks down.
and nitrous IS FORCED INDUCTION because nitrous is not available for the motor to NATURALLY ingest.

Force:
The capacity to do work or cause physical change; energy, strength, or active power: the force of an explosion.
The engine's vacuum is the only thing drawing the nitrous charged air into the motor.
FORCED induction... meaning work is required by something to induce it into the motor. IE. something mechanical like a turbocharger or supercharger. Nitrous jets do not FORCE air into the engine. To do so it would have to have positive manifold pressure.
Increasing the amount of oxygen present in the mixture seems to be what Chet is talking about. If thats the case then me driving my car down a mountain face is forced induction because the air suddenly becomes enriched with oxygen the closer to sea level I am. If I put a cold air intake on my car it's forced induction, if I put a piece of ice on my manifold it's forced induction, if a cold gust of wind blows into my engine bay it's forced induction by that logic.
I'm sorry, argue all you want it is NOT forced induction.
