right now I only have $260, but im just getting started, I look at it this way, there is a car for everyone, not all cars will suit everyones needs, I did not know the MSP existed until I had to find a replacement for my 02 protege ES (still miss that car), I found the MSP's by accident while scrolling through pages of used car listings online. I knew it was the perfect car for me, it already came stock with everything I wanted my ES to be but would take forever to obtain. I liked how it has many mods to suit almost every need and allow for each MSP owner to make their car their own and something unique from every owner on this forum. I also know what it is like to have a car that you cant go any further with but you cannot sell because of the money invested. I had a car that i had the aspirations of making my own and like nothing any owner of that car had ever seen, i planned on having the car awhile but sadly I realized I could never afford what i wanted to accomplish but with the miles i could never get the money back I spent. The decision was taken out of my hands when i wrapped the front end around a mailbox, followed by a telephone pole. The ironic thing was I got more money for the car from the insurance company that what I was quoted at Carmax for a trade-in value. My point is maybe it is worth losing the time but making the money back by selling to a young kid for the value of the car with the mods or putting the car back to stock, selling the mods and getting out. You gotta do what makes sense for you, but you gotta do it before you get any deeper into this car in time or money. Thats my 2 cents(mp3blue)

You just said the turbo "stuffs" the air from the intake inlet into a smaller space. That means the air is denser, i.e. greater amount of air the MAF has to read at a certain time. Just because the same air that came into the intake inlet eventually passes through the cold pipe, doesnt mean the density is the same at the throttle body as at the intake filter.
Again, turbo compresses air or in your words, "stuffs" it into the intercooler piping. The MAF has to read a denser air (larger amount of air) on the cold pipe than it would read at the intake filter. Again, at the intake inlet the air is at atmospheric pressure. The air is less dense and the MAF measures a smaller amount of air at a certain time than if it were on the charge pipe (again, where the denser air is passing through the charge pipe).

you are failing to account for the fact that the air going into the turbo is going at a higher velocity. PV=nRT
think about it. if there is consistently more air after the turbo than before it.... where is that air coming from?
but again, the air is denser in the charge pipe. The denser air is passing through the MAF and being measured. The MAF measures less dense air at the beginning of the intake. Less dense meaning a smaller amount of air molecules. In the charge pipe, the MAF measures compressed air molecules meaning a greater number of air molecules at the same time period.

you just aren't grasping the physics of this. Mass air flow is just that. the MASS of the air flowing through the pipe. which CANNOT change just because its pressurized. when something is moving faster, it does so at a lower pressure. this is the principle on which Lift is based (aerofoil). on the front of the turbo, the mass is say 20. its moving at 10 m/s, and it is at 15 psi. (these numbers are obviously just for the sake of example.
after turbo: still mass of 20, speed would drop to say 6 m/s, and pressure goes up to 22 psi.
point being, the mass (moles) stays the same.
and i am still arguing the density is different...

and I'm not contesting that. but just because the air is more dense doesn't mean theres more of it. we're not talking about a sealed box, we're talking about flow.
i realize you're in pretty deep here to admit you're wrong... but... seriously, cut your losses dude!

I'm with Wagonbacker9 on this one.
MAF sensor - MASS air flow, which measures the MASS of the air. All of the air passing through the valves and into the combustion chamber, no matter how compressed it is, is still the same amount of air that was read at the MAF (unless you have a leak somewhere).
This is why they use MASS airflow sensors, and not volume sensors.

wtf does air going thru the maf have to do with your best/worst moments with your msp?

yeah, pretty bad thread jack. sorry guys.
Mazdaspeed2oo35
600whp - 600wtq at 30 PSI
im sorry for the thread jacking but im desperate looking for ACT Extreme Pressure Plate Part # MZ-018X does anybody knows from where i can buy one, i really need these Urgently. these is for a Mazdaspeed Protege or Mazda 626. any help would be highly appreciated !!!!

though technically, one could say that this is half the reason these cars are both so fun, and such a pain.. at their respective times.
glad we can go from one thread jack seamlessly right into another though. haha
Side not on the air mass question: if you take a given mass of air before turbo that occupies a given volume at atmospheric pressure, you compress it with the turbo to a certain pressure, the same mass will occupy less space. If you compare a equal volume of air on both sides of the turbo, the volume after the turbo will contain more molecules because it is compressed (density=mass/volume), therefore more air molecules available for combustion for a fix space available in the cylinder. The MAF is a heated resistance that calculates the velocity of air by associating the heat lost caused by convection with the required speed to lose such amount of heat. You can then correlate to a volume and a mass of air since you know you are at atmospheric conditions.
Now, back to the purpose of this thread....
Best moment: When I picked up my MSP at the dealeship and drove it home blasting Civil War throught the speakers
Worst moment: When I got home and my girlfriend test drove it, revving the engine to 5000 RPM and droping the clutch with the hand brake on....I almost cried.....

she would of gotten the **** out of my car real quick after that

wow, why the hell would she do that, and i thought i was being dangerous teaching my girlfriend how to drive stick in my car (only conked once becuase she knows how obsessive i am about my car so she is real careful)

yeah.. i wanna teach my gf how to drive stick, but the clutch on my subie is way too touchy... and idk if anyone will drive my next car barring some emergency... lol
