Cool site!
Very informative and interesting. Especially for those of us using CAI's. While placing the filter into an area where the air is cooler we are not necessarily helping the positive pressure into the intake. Are you gonna build a Manometer and do some testing?

The other thing that struck me was to try to find out if cutting a hole of some kind in the bottom cover of the front quarter panel might incrrease the amount of air pressure at leas into where the filter is. OR finding a way to bring higher pressure from somewhere else into the filterOr just forget it all and modify my stock airbox with a PVC pipe and sell my sweet looking carbon fiber MHP. It would be interesting to see the measured differences between these approaches though.
It interesting to note as well that this is the kind of performance that can't necessarily be measured on a dyno because it take air pressure being "forced" for the positive pressure to actually happen. Something that can only be seen while actually driving the car! I guess you could use a GTECH meter to see if it improves you 0-60 times or some 1/4 mile runs.
 
Also I wonder if that PRM velocity stack air filer thing can do something to get rid of negative boost?
 
I was hoping to do some testing when the weather get's a little warmer. I'm still trying to figure if it's worth buying the gauge or just doing to two-liter bottle trick.

I can write up what I find out if you guys want...
 
ok, i'll be the one to ask...what's the 2 liter bottle trick?

two liter bottle trick????
 
In the article about taking the negative pressure out of your intake system, it says you can make a gauge out of a two liter bottle filled with water. You measure how much water is sucked up a tube, this directly relates to PSI in the intake. Obviuously, the higher the water goes, the more negative pressure (or negative PSI) there is in the intake system.

Voila, the two liter bottle trick...Intsead of buying the gauge that the article also talks about...
