this has now become another waisted nitrous thread. Eventualy I'll learn not to comment on any of the nitrous threads that are created. Sorry, it was my own fault.
I just wanted to know what method worked in measureing the bikes actual VE so perhaps I would be able to perform the same tests on my own. I didn't intend to get sucked into this whole stuff (for a lack of a better term). oh well.
so now it's a different question that you're asking and it's no longer VE related.
How much volume a cylinder can hold if it's TAF (theoretical air flow) is 296 @ 100% VE would depend on many additional factors. Therefore any answer I give you can be proven both valid as well as invalid.
Again, I don't wish to play along in this stuff.
Sounds to me your the one dancing. You posted yourself that a spraybar ensures a even load and now you say it depends of how the motor is? WTF?So tell me how does the enigine knows how much air it needs to be a even load?
NO NO NO......see there you go AGAIN, trying to spin, you asked whats the difference in using a spraybar vr's fogging the air box....i answered "to ensure a more even load on rotating assembly"
Then you asked how much could a cyl hold....i answered "it depends on a lot of different variables"! NOW WHO'S DANCING?
The short answer would be for you to say how you measured the actual VE of you engine to determine it's at 90 whatever percent as you stated. There is no long answer to the question.
Your books at home can't tell you or me what the actual volumetric efficiency is for my engine combination. btw, you haven't added any knowledge on anything for me.
So to ensure a more even load on rotating assymbly you add nitrous to all 4 cylinders evenly, correct? Is that what your saying?
What im saying is that a "spraybar" puts a more even load on the engine compared to "fogging" the air box, and WILL make more HP in doing so!
why is this so hard for you too understand? how come on wet kits they install a nozzle per cyl(direct port)? Why don't they just put one(or two)nozzles in the front of the air box and let the air charge take it in? ???
I've only asked you two very basic questions. Both of my questions were directly related to statements that you made within this thread. Neither question that I've asked have been answered by you. Instead you simply ask different questions.
Again to answer another question that you have:
The volumetric efficiency is the actual volumetric flow rate divided by the theoretical volumetric flow rate multiplied by one hundred.
To determine the actual flow rate multiply the mass flow rate (MFK) by the density of the intake air (d2) at that specific mass flow rate. This gives you the actual volumetric flow rate of your engine.
To determine the mass flow rate is where you need a sensor to actualy give you a measurement. This is what I wanted to know from you is what you used.
Given a mass flow rate for air, you must have the density of the air to find the volumetric flow rate. Density is proportional to the temperature and can be calculated for any temperature. The density of air at 32 °F and 1 atmosphere is 0.0808 lb/ft3. (I had to look this up because I didn't remember this off the top of my head). Knowing the density of air at a given temperature, you can use a ratio determine the density for the incoming air temperature.
You already know how to calculate the theoretical air flow in cubic feet per minute (cfm) so I wont include that here.
That is true. If I have a theoretical VE of 296cfm, how can I get the actual cfm that the motor has?
re-read my post. Your answer is in my response. "To determine the mass flow rate is where you need a sensor to actualy give you a measurement". The sensor I would assume would be a mass air flow (MAF) sensor. That's why I posed the question to you in the first place. I wanted to know how you did it so that I wouldn't base things off of an assumtion.
I keep answering your questions and you've yet to answer either of my 2 very basic questions.
If you would answer my first question you would have the answer to your most recent question. Since you already stated your VE is 96% you must have figured out a way to determine your mass flow rate. Right?
