what porting though?? bridge? or extended dtreet port??

 

This is with an extended street port and massive exhaust ports.

 

bar boost * 14.7 = pounds of boost

 

very informative posts

 

oh wow... there is a whole world of disinformation in this thread!

The entire theory that pressure is pressure is totally WRONG! wow the amount of volume over a given pressure is dirrectly proportional to the area of the compressor Blades. there are of course other variables that come into play, however here is a formula you need to look at;
This is a derived version of the Ideal Gas law... which is hugely used in thermodynamics. is attached see the bottom of this post for the formula.


Here is the deal... as you can see the same substance air which we will treat for ease of argument to be a Noble Gas.
now ;
P1=1 bar
P2=1 bar
T1=40 Deg C
T2=80 Deg C
V1=3m cubed.
now if you go ahead and plug in the above into the formula and solve for V2 you will find that it does not infact = the same amount of volume. it infact equals;
V2 = 6 m cubed

Now that showes that temperature plays a crutual role... so ignoring it does not make any sense.
Now lets assume you have a compressor of specific area of .01 m squared and compressing air to 15psi at 70% efficiency @120,000 RPM.
and you have one of .005 m squared compressing air to 60% efficiency @120,000 RPM. and do a little complicated formulae and math, u will find that the compressor with a higher efficiency will have a temperature 33 degrees higher than the compressor of half it's size and less efficient at 15 psi.
so as you will see. using the above formula again.
adjusting ALL THE VARIABLES FOR THE ABOVE INFORMATION;
P1 = 0.6 bar
P2 = 0.7 bar
T1 = 40 Deg C
T2 = 73 Deg C
V1 = 3.0m cubed
V2 will = 4.692 m cubed

So now concidering larger compressors are generally more efficient and the same level of compressor than a smaller one. now that I have mathematically proven that a larger compressor pushes more volume at 15psi than a smaller one.
If you need an explination go to your local university text book store and buy a first year thermodynamics text book read and learn it, Or pay for the class at the university then return and please enlighten us with the same information that I have provided vs the incorrect information portrayed earlier in the thread!

Just for sake of completeness, there is also another formula that includes the variable Z which is the compressibility factor, which further helps point out that pressure is not pressure.
