Well the generic answer is bore x bore x stroke plus adding in piston to head clearance, piston specs, compression ratio, fuel requirements, etc. I like to give you a more exact answer so everyone can follow. There are a bunch of factors to get the actual VE instead of theoretical VE. Excuse me for being so technical.
forget it... a simple mathematical approach would be to multiply the mass flow rate (MFK) by the density of the intake air (d2) at that specific mass flow rate. What I was looking to know was how you are measuring the flow rate (such as using a mass aif flow sensor) and determining the density based on the intake air temp (the busa even has a sensor already for this which is the IAT sensor in the airbox).
never mind though.

Hummmm..... equal load on rotating assembly! :stoopid: Whats your book say? :leseratte:

So if thats true, how much load can each cylinder take? Why would it matter if you sprayed nitrous down each cylinder or just fogged the airbox? Don't hate on books, thats where learning comes from. You should get a few.

Maybe the answer your looking for isn't the question your asking. Right now I'm explaining how much a cylinder can hold, not what flows too it. Since its simple tell me if I have a cfm of 296 @ 100%VE what would decrease that number to 90%? And I'm not talking about flow, I'm talking about volume.
even though you never answered my question I'll reply to your question. Either RPM and/or Displacement would effect the theoretical VE. This doesn't account for atmospheric conditions.
btw cfm means cubic feet per minute which is flow not volume.

after re-reading your last post several times I'm trying to understand while you're now talking about volume (maybe cylinder volume) with Volumetric Efficiency. For VE the volume a cylinder can hold has no relevance.

How much load each cyl can take depends upon ALOT of different variables, what kind of pistons,rods,cyl head,quench(comp ratio) and list go's on and on!!! Why does it matter how nitrous is disspersed?, well i thought we already covered this, but maybe you were not paying attention....TO ENSURE A MORE EVEN LOAD ON ROTATING ASSEMBLY!!!
Books are great bro, but it seems like all you like to do is quote theory's and then when asked a direct question(HOW ARE YOU MEASURING/WHAT TOOL YOU'RE USING FOR "VE" ON "YOUR" BUSA TO COME UP WITH THE NUMBER YOU THROUGH OUT?)you dance around it by giving us more theory's/formula's, anyone can use google
. But hey, i gots no issues with ya bro.....you make my day at work fun....like i said before I LIVE FOR THIS $HIEOT!

If you read my earlier post you would see I said what cfm means. I also stated that I was doing it at sea-level-standard-day. How much volume can a cylinder hold if there is 296cfm?
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.

BTW, what have you shown to prove him wrong, and that your way is more efficient? ???
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?
btw, "tell me if I have a cfm of 296 @ 100%VE what would decrease that number to 90%?" was my answer to this incorrect?
