If you don't understand that, go back to science class. Not trying to be harsh, just saying that psi is a measurement of pressure, not airflow. Quote: 100psi of air/boost would be one big intake restriction (i.e. feeding your manifold via a stirring straw) or a diesel turbine for a submarine. I never learned about "boost" in science class. I heard that word and assumed he was speaking of conventional methods of boost, ie: Turbo or Supercharge. Hence the cap off that would keep the greater 100 PSI pressure flowing into the cylinders.

This kills the air boost theory for the experiment(any disagreements to my thinking?) So would explosive gas injection (methane? ) be the way to go? 95 Contour GL V6 ATX full of little experimental mods that make me happy

Not to sound dumb but...I don't understand this part? Can this be expanded on a little? Missed this one. "Boost" is just a measurement of restriction/resistance. To generate 100psi of "boost" you would need a HUGE impellar or a HUGE restriction. Passing air through a stirring straw is a HUGE restriction for an engine. Therefore you could generate 100psi of resistance before the straw but flow maybe 1 CFM after it. "Boost" numbers mean little to nothing without the information to generate airflow on a specific engine with a specific compressor driven by a specific turbine. Basically stated. 2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.

If you could actually pressurize a 2.5L intake to 100psi, what would the effective displacement of the engine be, or in other words, how "big" would a naturally aspirated engine have to be to consume the same mass of air/fuel mixture? Go ahead and assume room temperature air for this fantasy engine. 1. Too many variables. Pressurizing the intake to a specific PSI is one thing. But CFM flow to the engine because of it is another story altogether. If you mean raising the cylinder pressure to roughly 6.8 atmospheres (14.7psi natural plus 85.3psi "forced" ) then that's your answer. 6.8 x 2.5 = 17 liters of effective displacement. Provided of course the temperature doesn't change. (100% efficient intercooler - hey this is a fantasy setup ) However this is only applicable if the engine is being force fed. Like discussed previously just shooting air into the intake does nothing because CFM draw is dictated by the engine's displacement and volumetric efficiency. Quote: How about at 6 and 9 and 12 and 15 psi (practical pressures)? 2. What if the pressurized air is at 200 Fahrenheit? 3. as opposed to 100 deg F for naturally aspirated? 1. Just derivations of the previous calculation. Provided if you meant 6, 9, 12, & 15 psi "above" normal atmospheric pressure of course. 2. BOOM! Detonation is a biotch... 3. Air density drops as temperature rises. How in-depth do you want this fantasy formula? It's late and I really don't want to break out my old physics books. 2000 SVT #674 13.47 @ 102 - All Motor!
