Why a Supercharger or a Twin Turbo is needed in a G-35

[Jacko3]

C-Kwik:

In the world of arcane physics, anything rooted to this earth by the weak forces of gravity, is actually falling, even if it does not appear that way. Falling is not used literally, as most people would like to understand it.

I never said gravity was not a constant force. I only possed to you that depending on the vector force, the effect of gravity cannot be the same depending on which direction the body is moving.

Did you notice that I said that the velocity of light is constant, however, when in a vaccum? What Einstein postulated, was in a vacuum--all things being equal. Well, the real world is not a vacuum. It is doubtful the theory of black holes is in complete and total acceptance in the science world.

Yes, gases do experience changes. For example, if you were piping NO2 through a pipe using impellers. If the volume of gas starts to drop, as a result of say, changes in temperature, it is possible for the Nitrogen to seperate out from the oxygen. When this happens, the density of the main fluid or gas reduces, thus, providing opportunities for one gas to exert a different pressure than the main gas, which leads to cavitation because all pumps and impellers are built for specific viscosity of fluids, which also depends on the fluids density. This problem of seperation of components of gases is a real engineering problem in the real world. To ensure cavitation does not occur at the pump, engineers have to figure out how to pipe a gas over long distances while ensuring the components of the gas don't seperate out.

Shafts,bearing, etc, are not operating in a vacuum. They have air or other gases around them, and so, they are subject to a terminal velocity, because they are affected by acceleration due to gravity. You used an example of a feather falling through air. Try turning the feather horizontally so that it is moved through air by a force. Yet, do not forget that the acceleration due to gravity is still acting on it as well. However, terminal velocity of a body falling vertically will be different for the same body moving through air horizontally. without a doubt, the feather moving vertically will approach terminal velocity faster than the feather moving horizontally. Thus, the feather moving horizontally would likely reach its terminal velocity close to its maximaum velocity.

Still having a great time, more popcorns for me

AZhitman:

Speak for yourself. The results you present are magazine results. What if the driver of the Masda 6 speed you present was not as good as the driver of the G-35? Or, vice versa. This is a possibility.

I think you may have had more fun poking a grizzly in the eye with a stick..

[Jacko3]

Azhitman:

The fact is that each auto magazine has its own interest at heart. In addition, driver skills cannot be overlooked.

I don't remember reading every auto magazine agreeing or producing the same results on the same cars, all the time. Bias is a natural human propensity.

I personaly don't like the looks of the Mazda's and i have heard about transmission issues with them (don't know how true this is).

Anyway, I need me some popcorn right now,

Jacko, you seem okay sometimes, and other times you seem like you skipped a dose of Lithium, Adderall or Wellbutrin.

I don't understand WHY in the G35 forum a thread about superchargers and turbos gets turned into the theories of gravity?

This crap should be in general chat, not in the G forum.

[USAF_G35_Guy]

C-Kwik:

Well, the fact is that gravity is a weak force. it is weak enough so that humans can produce enough force to overcome its ability to pin us to one spot.

Jump out of a plane without a chute.....then you'll see how weak it is!

......Just because it's not pinning us down, doesn't mean it's weak.....I just like to think of it as, I'm just that strong! HAHA

Oh BTW.... ......but it's kinda like a car crash, it's just so hard not to look at it so I'm sure I'll be back later to see what other nonsense is going on in the thread!

But I do agree.....the 350Z's and G35's should have a factory turbo or SC option. The RX-8's could definitely use a factory turbo option as well. Ya, that car (the upgraded model of turbo car X) is gonna cost more, but it's just like a WRX or WRX Sti. They have the option for you if you want it, and can sell more cars that way cause they'll cover more of the spectrum/market with more options like that. Hell, even the already bada$$ new GT-R is gonna have an upgraded model in the GT-R V-Spec in 2010. But the past is the past and it looks like Nissan/Infiniti have learned their lesson and will have a more wide array of models to prove it!

+1 on looking forward to my next Nissan/Infiniti !!!.....used GT-R in 2011,12?

somebody owes me ****in' tylenol for reading this.

[KoukiS14]

The 350 was designed with the idea of a linear power delivery -- it's not meant by Nissan to have turbo, or any other sort of forced induction (although it's baller if it does). How come the warranty doesn't cover these mods if it's what Nissan WANTS us to do with their vehicles?

edit: my mistake -- we're talking aboot gravity now. I'll step on outta here.

[WDRacing]

Fact 1For the record, NA will always make less power then forced induction...always.

Fact 2Jacko knows damnit about turbo's and this whole gravity vs boost thing is an obvious attempt to use collegiate level words and theory that has gone horribly wrong.

Back to playing with blocks bro...seriously.

[adren77]

So you are saying my can of soda, sitting on my table is falling? It is not. Perhaps you are misusing terms here, but it is remaining motionless on my desk. The force of gravity is acting on it. But it remains motionless, because there is an equal but opposite force acting on it. That is, the normal force from the table.

Are you serious? Think vectors here. If you have a force pushing on an object horzontally within the field of a vertical gravitational force, then guess what, both forces will act on the object. Gravity does not decline unless the gravitational field itself becomes weaker. This can occur in areas where the mass/density is lower. It also gets weaker as you move away from the source. Otherwise, it is a constant force.

Umm? Albert Einstein proved light is affected by gravity. Black Holes are simply small dense stars that have a gravitational force so strong that even light can not escape.

Terminal velocity is absolutely related to wind resistance. Drop a feather and a ball off a building. The ball will fall quickly while the feather will fall slowly. Now if, you remove all the air from the atmosphere, and do the same, both will fall at the exact same rate. This is beacause the feather has much more surface area for it's given mass, which increases the effects of wind resistance on it.

Another example is to jump off a plane. Open your arms and legs so that your body is open to the air you are rushing through. You'll stop accelerating towards the ground until you reach your terminal velocity/ Then close your arm and legs and either aim your feet or head straight towards the ground. You'll actually accelerate some more falling at a faster velocity until you hit the terminal velocity. By doing this, you change the amount of surface area being subjected to the air rushing by. This changes your terminal velocity.

Absolutely. Speed is a scalar and velocity is a vector. Now that were past the technicalities of it, how does this even relate?

Cavitation occurs when the molecules of the liquid vaporize. This occurs as the density of the liquid drops in the low pressure areas that occur when the velocity of the liquid moves past an object. When the density drops to a point below the vapor pressure of the liquid, it turns into a gas until it slows down and the density goes back above the vapor pressure. Then the gas turns back into a liquid. Gas can not experience a physical change like the liquid does in this instance. Therefore cavitation cannot occur.

An air filter, dirty or clean, is a restriction. A turbo that sucks more air through a filter simply creastes a lower pressure area behind the filter. As the pressure differential is higher, the flow will be greater.

I already explained cavitation so I won't go into more detail in the paragraph.

A turbo motor with a more restrictive or dirty filter will become a greter restriction (read: it would require more energy to reach the same intake manifold pressure).

C-Kwik you really amaze me. By now you should know you will never win any debate with Jacko3. I foresee this turning into another 10-page debate.

[AZhitman]

The misinformation this dillweed has posted should be a testament to his credibility.

Bottom line, Mazdaspeed 6 ain't "spanking" a G35. Period. I couldn't find ANY tests that could even be misconstrued as such. In fact, most were pretty consistent with the R&T results.

When you get some experience in the garage and on the track under your belt, then you can step up and lip off. Until then, you're playing way outside your league, kid.

[rn79870]

Dammmmnnn, 7 mods/admins checked in in the last page. I'll bet the mod forum is rather active lately, probably entertaining as well. I'd pay for a 1 day pass to that forum, yep I would.

[G_whizz]

LOL... how much

And yes it would be sooo worth it..

[Beezer]

Name calling....lets all resort to that now

[rn79870]

Jacko3, Slow down, take a deep breath, roll up the windows, turn on the XM and enjoy the view. Life isn't long enough for you to beat every car out there so why worry about it?

In other news I was beat by just about every other car on my trip to the library to get Words that Work by Dr. F. Luntz. A great book if you're looking for something to read.

[WDRacing]

It's the nature of the beast my friend.

I ask you what is worse, the meaningless blather of a single person that confuses and irritates the many or the single person that silences the fool for the sake of all?

USAF, with only 1500/yr. (Or so I believe the number to be) they are going to be rather scarce. That may drive the price of a used one up to or near the price of a new one. Better start saving now...

I want to see what the $3000.00 "special paint" option is, anyone know?

[!979TransAm]

also if anyone picked up on it yet, google velocity and speed and you will see exact definitions pulled from the google search. If I remember right jacko got on a certian mod about searching the net for answers. BTW I searched to double check the defintion. I thought I had confused velocity with vector but then remembered they were both scalar quanities.

Oh well I stayed outta this one because of the last 10 page arguement showed the train wreck created by theories applied without experience. I don't know everything of course and will be the first to tell you. I'm always up to learning new concepts

[smockers83]

Of the 4 forces of nature, gravity is the weakest at the atomic scale, but it dominates over scales larger than 10^-6, which is the typical distance between molecules. Therefore gravity is not a weak force in our application. It is not electromagnetism, the strong nuclear force, nor the weak nuclear force that keeps us in orbit of the Sun, it is gravity. Humans can also create the conditions for overcoming both nuclear forces as well. The problem here in the two arguments is that Jacko isn't taking things into context.

Terminal velocity has everything to do with resistance under the explicit definition of terminal velocity.

Light also has a constant speed anywhere, according to special relativity. Gravity does have an effect on light in a vacuum. In outer space, light bends with the forces of gravity as it follows spacetime--a star behind the Sun, we can see because its light is being bent around the Sun as it follows the curvature of spacetime.

Things are not said to be in a constant free fall, especially here on Earth. What is said, however, by Einstein's equivalence principle is that an inertial reference frame and a freely falling reference frame are equivalent. What that means is that something that is accelerating at 9.8 m/s/s looks and feels exactly the same as the force of gravity. Gravity is a constant acceleration, but when a force acts in an opposite manner an object is no longer in free fall. Us humans are not in constant free fall, however, we are constantly moving. Everything orbiting Earth is in constant free fall, Earth is in constant free fall around the Sun. But one can say everything is always falling because there is no privileged reference point, but for simplicity and understanding we should state what our reference points are from now on, as again things are being used out of context.

[Beancooker]

Didn't anyone notice where I had said that the theories of gravity should be discussed in General Chat, not the G35 forum?

I have to go to the store. I see a lot of deleted posts/blather in the near future...

Could you be referring to the bolded text in your post on page two?

[AZhitman]

movement in a horizontal way is actually a counter effect to the horizontal effects of gravity. And. if you can move fast enough horizontally, the effects of gravity declines considerably and not totally.

More erroneous info - Need we break out the old "bullet dropping" physics example?

[Minmey15]

Jacko has been speaking for Nissan engineers. How G35 and 350Z are meant to be. I disagree with Jacko after reading interview with V36 engineers, however, he seems to believe G35 and 350Z are race car like compared to.... Accord.

Jacko loves to debate, and most of his threads turn out to be like this one. And once people start to bash on him, he disappears and start another one. I feel like he would go all over to back up his theory, and his behavior is often childish.

But I like reading his thread for some reason. It makes me laugh, reading a kid thinking G35 is a race car. I just hope he will be safe to himself and others on street.

[Jacko3]

Dear Beancooker:

Beleive it or not, I was just having fun with C-Kwik. I am sure C-Kwik understands. Now, take a read of Minmey15's comments, and tell me if you would like such remarks?

Yes, some days, I take my meds and some days, I forget where I kept them the night before

Look, it is all in good fun. Debating with C-Kwik does not mean I don't agree with him. Science is multidimensional. And, beleive it or not, during the design of our cars, this same debate style goes on with the engineers as they decide what best to use in the car. Nothing is clear cut and dry, until the car is tested and found to be road worthy.

Anyway, I really liked the responses of everyone who made attempts at explaining the phenomenon. You all rock!

As always

Koukis14:

Three months ago, I walked into a Nissan Dealership and found a brand spanking new 350Z, all souped up with Stillen Supercharger with a price tag of $49K--with everything covered under warranty. I know I am not blind. They actually tried to sell the car to me. I am of the firm beleif that Nissan intended for us to modify these cars as best as we can.

[SVTCOBRA]

Perhaps the engineering debates should continue in General. I'm sure there will be more colorful comments there....Should be lots more fun for you.

Azhitman:

I could not keep up with a Mazda 6 speed. Period! I can't be in a state of denial about my G-35 Coupe--it ain't as fast as you would like it to be. It is too heavy. It may require forced induction in order to get its groove on with the Mazda 6 Speed.

[Jacko3]

Minmey15:

I am glad I bring joy to your soul. The magazine I read (I can't remember which one becasue I read it at a Barnes and Noble) noted that Nissan Engineers are not happy that most 350Z owners are not modifying their cars the way they had hoped, in order to take advanatge of the full potential of the 350Z. 350Z and G-35 have the same engine.

Nope.

Just needs a better driver.

It's OK, you're much better at typing than driving, I'm sure.
