good theory but not exactly. when the air compresses in the intake track it doesnt put more air in there. liek for example, take the zex air filter with the nitrous bung in it. it shoots nitrous in the air intake for the specific reason to do such idea, but when you add the nitrous and the air in the intake your gettin more cfm through the intake. but dotn forget when you spray the nitrous your adding n20 particles in the air intake alog with a few more aid molecules. it allows more room for air to enter in intake track by compressing it
now say if you have a intake for arguement sake that flows 300cfm well say. you spray nitrous in there you get an extra 40cfm ok, no that nitrous doesnt hit the motor at all when sprayed at end of intake track. its disapated by the time it hits motor. ok here example number on.
number 2, is if your runnign dirrect port nitrous oxide in your motor. its put in the intake track at the last second. dirrect port is at the very end of the intake manifold right before the head. you have no more tim eto add more air in there. the air in the intake track is allready there over and done with waiting to make its way into the head. when the nitrou s hits it say you have the same cfm of 300 then add nitrous on top. wont give you anymore cfm and will add nitrous to make the power. now say your running a 75 shot, you will not see 75 hp form this unless your motor is the most effecient it can be. but with different atmosperical pressures, elevation, and humidity it wont be. at any given time in a natural habitat your motor will not run 75hp form a 75 shot due to variations in the air.
number 3, say you run same 75 shot but in the intake track right before the throttle body. same hting you wont add any more air into the intalke track. the air in there is compressing to get the nitrous in there. its basically moving out of the way and adding the nitrous molucules in the air exsisting in the intake track. but same will go for number 2 i forgot to mention. nitrous disipates in the air while is travels to combustion chamber. dirrect port is the closest and you will see most gains form it as it has no time to really disipate. but some does. in the intake track it has time to dissipate so you will see less gains from it vs dirrect port nitrous.
ok i think im done. thats basically how it works on everythign ive read on nitrous and motors. it gets way in depth but that how i understood it in my words.
also i found that video link. linky no work but if you can get ti to work this is the dyno pull i was talking about. high hp and doesnt get the hpxshto size. sick video too

, yup kinda makes sense altho dsmjim puts it more eloquently :laugh:
then with the nitrous you say you go from 130whp to 170whp after drive train loss with a 75 shot? so now your saying a 46% drivetrain loss. manuals usually have 120hp to the wheels stock, or about 15% drivetrain loss. you say our cars make 105whp stock and you have 122whp with intake and 3" exauste? sooo almost 20hp from intake and exaust... come on...
... I think w/o cams 200whp on a 75 shot of nitrous is going to be very, very tough.
