You're that far, put a psi guage in the hole...

So you raise hell about ram air being a "HOAX", flat out say it is bullshit.....and make a post to ask everyone on the board to see if it works???
Man O Man.......LMFAO.
I know MY IAT's are lower than a CAI, that means cooler air which mean more power.
If you REALLY think a 3 foot long CAI laying against a 200 degree radiator with 2 90* bends, 18 inches from the hot pavement, enclosed in the fender. makes MORE power than a straight shot of 12 inches from a high pressure area OUTSIDE the car....I TRULY can not help you.

Then we see the difference in percent of IAT tempts to ambient, and viola. Its science!!
It would be interesting for someone with a g-tech or whatever it's called and an aftermarket hood to get together with someone with a stock hood and do a few runs each way and see how much the averages vary by, or even cars at the track to swap hoods and see if they can tell anything. I don't imagine it's much for any street car in the 1/4 though. Like I said before, maybe a little for lower IAT.
Exactly! a full front ends worth of air resistance is not going to force its way into two fist sized holes at 120 mph! I can understand a huge scoop opening at 250mph...but a street car? c'mon!

....ok i got it!!... your mouth = throttle body, go get a high pressure hose and try drinking the water fast enough that it doesn't start spraying backwards(back pressure). kind of hard? that's because your body (ECU) is only programmed to drink (intake) so much fluid (air) at the givin speed at throttle...Yeah, maybe if they were basketball size openings it might do something.

Yes, but you could lessen the margin of error by averaging multiple runs and comparing the averages, the more runs, the less error.

Why do you think a stock car can run just fine in Denver and drive the same car to Miami? Way different hp in those altitudes and air ingestion capabilities.
In Denver with the ambient temp at 95* and Houston Tx at 35* do you REALLY think your car is taking in the same amount of air under WOT?
The engine will ingest as much air as it can,Positive pressure in the intake tract makes it possible to get even MORE down its throat, the ecm is responsible for adding fuel....you are now touching in an engines VE capability.
AND AGAIN you describe EXACTLY what ram air is, keeping the plenum/filter box in positive pressure.

You can't compare air and water, air compresses very easily relative to water that compresses so little it basically doesn't. Sort of like brake fluid, the pedal is solid until you get air in the system so it gets soft.

i have braught my car to a number of different places and i do understand what you mean. i have drove it in FL where i lived, NC, NY, NM (HIGH elevation), texas ECT. so trust me, i do understand all that. you have a strong arguement, but you picked the wrong side to study. as you can see, everyone here agrees it works, but hardly.

Are you guys "discussing" that a Ram Air compresses more air into the motor over a CAI or simply which one yields lower IAT's? I think the gains get miscontrued when lower IAT's are obtained (more hp) and people classify that as a "raming" effect.
In a N/A state a motor is only going to pull as much air as it needs. There is no raming force like a FI car. Ever try sticking your head outside the window at 100mph and try to take a deep breath through you mouth? Your lungs didn't explode did they? Why? My $.02 -Mark
