I'm bored and an idea popped in my head.
If I had a small air compressor in the back seat of my car,and the air line connected into the little plug bung on the CAI of our sixxers and when we went WOT the air compressor would activate via a pedal switch to throw 7 or more psi of air into the CAI what would happen? Nothing? Phuck up my engine? Like I said its not a plan just a thought

The compressed air would most likely flow both ways, like even through the air filter going out.

But when the engine is at WOT it sucks in so lets take into consideration that maybe we lose 50% through the filter, doesn't mean we cant up the compressor "boost"

The engine always "sucks in" when it's running. Yes WOT it "sucks" more lol, see what I did there? :bowrofl:


Try it and let us know :shiftyeyes

shooting a lot of unmetered air into the car isn't a good idea....

at best you will get a lean condition, the car will retard timing and dump fuel and it will run like ****

at worst you will get some detonation and maybe fry some pistons

Yeah that makes sense, like I said it was just a thought,i want even gonna try it

Your car takes in way more air than any compressor could dispense that would fit in a car relatively easily. Even if injected before the MAF so it would be metered it wouldn't work... good thinking though

Just wait man, I think that this new idea has some serious potential.

Im assuming by the lack of your reply my description wasnt too good, here is a quick picture I made to explain the new concept

Wouldn't work for a number of reasons-

1.) You'd need to push the air upstream of the MAF, or be running a MAP setup.
2.) You'd need an effective way to shut the normal inlet path to keep a large chunk of it from escaping elsewhere.

But the biggest reason I see is the physical limits of trying to push enough air to make a difference. If you're trying to make ~400hp I would expect you to need around 40lb/hr of air. That is a LOT of air. You would need to have a very large reserve tank, and pressurized at a very high pressure, as pressure will decay and become unusable as it empties. That's not even taking into account losing a large portion out the intake.

Just think about how much energy it takes to boost the air intake charge. For a roots blower on low boost, you're talking a good chunk of crank horsepower just to compress that air. With a turbo think of how much very hot, high pressure gas it takes to provide that large of an air flow with the compressor wheel. It's just not practical.

This. Except the high pressure part. The only pressure that plays into a turbine is back pressure. The less, the happier the turbine. It's the expansion of said hot gasses that spins the turbine.

Just an FYI on blowers, Top Fuel dragster units take 500HP just to run their blower. Let that sink in for a minute...

lol

So, do you realize how much air flow it would take to make +1 psi in your intake system. It has to be enough air and fast enough at that to fill the entire intake tube, intakes, heads, piston with that much extra air.

Now that may not sound like much but think of how instantly you would have to do that ....
Plus as said before that pressure would just bleed out from the air filter location.


Now if you had a huge bottle of pure oxygen ... you might could get a small increase that you probably wouldn't notice .... just because you were increasing the amount of O2 particles ... but then you run into lean conditions if not done correctly as said above.
