Default Air compressor and some hose= Major cheap HP?

OK, I have thought about this and it seems like it would work great to me. Here's the plan. Mount my air compressor into my truck bed. Fill it up to 150PSI. Run the air hose and connect it to an electric sprinkler valve wired to a WOT switch, and have the hose after the valve tapped into the stock air box. Set desired CFM rate by regulator on air compressor. Go WOT, sprinkler valve opens flow of air goes into air box, and runs through the MAF (fuel compensation) and you have a forced induction set-up. It would be set-up just like a dry shot of N20, but instead it would be compressed air, which is cold,100% effecient and extremely cheap to rig up.
Wouldn't this work? Why pay oodles for FI set-ups when you can tap and thread an air hose and run your air compressor to create boost.
What's your thoughts?
Cost to me would be $12 sprinkler valve, wiring, a WOT switch and some thread/barbed fittings.

what would stop the air from blowing out the front of the air box, you would have to seal it off but if you did that your motor would not get any air under normal driving conditions

I have seen a guy running a bottle of compressed air and using it to blow air in front of the MAF. I rode with him and felt a slight gain, but to verify that it did gain anything at that time i used the TAZZO. We didnt have a dyno at the time and the guy would never pay for a dyno anyways (Which cost more than his Forced Induction system ). Anyways he gained an avg of 2mph(20HP) in the 1/4mile by turning the bottle open from behind the seat LOL, but that was it. I wouldn't be comparing an air compressor to a SC or Turbo which flows over 1200 CFM in most cases. Anyone can tell us what does 150psi of compressed air translate in CFM? I hope its over 550cfm at the least to see some gains.

Same set-up as dry shot of N20, it would be acted upon at WOT and would be spraying right in front of the MAF, I want to know if 150PSI of pressure would yield good CFM ratings to get some HP.

Just have a very large brass "L" fitting tapped into the air box and the L part points down toward the intake tube/MAF or something better which I can't think of as of this moment.This would be on a 4.8 litre truck too, so the intake is different than that of LS1 guys.

Yes, I may do this over the weekend. I just want to make sure I don't run so much pressure (PSI) I will lean out my injectors. I would like to keep hearing y'alls thoughts and ideas please. This is an idea that might work great if we all put our great minds together.

Man the pressure coming out of the air compressor won't give u more than 20HP because i have seen someone who did it before and we did measure the gains. I dont think u will lean the car with an air compressor. As i said before you might see 10-20HP gain with a really high pressure air compressor or bottle and thats it. Don't expect anything more and again don't compare it to real Forced Induction.

If this isn't a joke and I hope it is...

The weight of the compressor alone will probably negate whatever power you make. If it worked someone would be doing it already...

Umm...yeah. This has to be a joke.

A good 80 gallon air compressor will flow around 28 cfm at 90 psi, less than that at 150 psi. Good luck using that to feed your motor.

28CFM lol.... The LS1 will suck that whole compressor in it ROFLMAO

No offense...but it will never work. As the others have said, there will not be enough CFM's to make a difference, especially on a V8. You obviously have not seen what a Blower does even at idle. My D1SC at Idle blows cfms similiar to a leaf blower on full bore. Remember too that's a 3" orfice blowing that hard. The short lived gains from a compressor blowing air through a hose and sprinkler head will hardly be noticeable IMO.

On a better note...keep thinking outside the box....that's where great ideas transform into technology!

Good luck with your efforts!

How much air flow can you get from your compressor vs. how much can your engine flow? My engine will flow at least 750 cfm but I have yet to see a 3/4 inch hose that can do that. I am guessing that you could gain as much by packing the intake manifold with ice to help cool the air. Just my thoughts.

If this was all you needed then why am I buying NO2? Why don't I just fill my bottle with Oxygen and inject that? Might be because the **** don't work. Go take a chemistry class, some engine technoligy classes, and you will find out how luticriss this joke is. It will not work, you need more then 150 psi behind a water hose to move enough air to feed an engine. There will be no incress in manifold pressure because it will blow back out the air cleaner box. even if you had 150 psi coming down a 3" hose, the air box is open on the other side so the air will leave in the path of least resistance. You would still need to seal the air bock off. I would suspect the reason you might see any power incress would be because you have just caused your MAF sensor to lie to the computer and cause the computer to lean or richen the fuel. You would do better to get a good profesional tune done.

But please, do not let me, a trained tech, keep you from screwing up your truck. I love making money off people like you. See you soon.

Actually PURE Oxygen would work. Of course I am not going to try it on my engine.

thats what i was thinking,
I heard the problem with running pure oxygen is that it burns way too hot and that it is pretty volatile, but if you could get away with it your bottle would last way longer
