Could it be done buy running some sort of compressed air into your intake like a turbo.. but different.. same concept.. different principle..

I wonder if I could run some sort of electric fan into my intake to get sort of a constant high power ram air???

ANYONE THINK ITS POSSIBLE

they sell kits like that on ebay for like $10.. just a little fan.. i thought they sounded good 2.. but i dunno.. might get more PSI outta a leaf blower motor

you know thats funny to hear that cause i have been wondering the same thing. I was thinking of taking a fan that they use on computers and trying to add that in somehow. The compressed air also sounds good cause it would be really cold when it came out. But how would you make that work. And what would be the benifits of hooking up a fan, i mean would you get some gain out of it???

I do a bit of work with compressed air... I was a big paintballer and was sortof a closet airsmith...

I was thinking this same thing. I could take co2 tanks, put some compressed air in them, and then basically just ram it into the manifold. Only problem, you have to retard the timing, which you can do if you have an MSD, and you also have to let the ECU know that it needs to dump in more fuel, or you´re gonna be running as lean as I am, weighing in at 124 pounds at 5´10"

Compressed air isn´t cooler than normal, it´s actually hotter. Thats why you´d need an intercooler for a turbo. Cold air is what you want. But that is an intriguing Idea...if any of you could make it work i´d like to see it.

No electric motor will produce enouth compression. Only solution is
to take a real turbo. Out of car you want and power it by leaf blower. Turbo spins on extreamly high rpms up to 100K Thats why it´s making so much boost. Leaf blower by itself will produce almost no results. Will help engine a bit but will give you no compression. There is only 2 problems with running leaf blower -turbo combo. First Leaf blower is not designed to run all the time. And you´ll have to tune up your blow off valve.And make something that will sense RPMS and adjust leafblower.

Now wait! Are we REALLY talking about forced induction using a leaf blower? LOL!

You sure on this?
I do know for a fact that in paintball when you fire off a tank quickly like I do
(rapid depressurization), the tank and gun will become very cold. Although this is specifically with co2...

But it also happens with other gasses, when you compress them, they bcecome quite hot, but then they bleed off the extra heat, and when they are decompressed, they become very cold.

In either case, you´d need to seal off in intake or something, otherwise you´ll lose all your compressed air out the "normal" entrance.

pumping pure Co2 in your engine would probably act like a bomb. "NOS" has a hair more Co2 than "air" does but its still below something like 40% I think. Someone who knows more about NOS will have to chime in. I don´t recall exactly what it is but NOS also helps cool and keep detonation down. Co2 while cold as hell when it comes out of the bottle as soon as it gets compressed in the chamber its going to heat up big time.

The leaf blower etc would never work well enough to make it worth it. At most you would be pushing 1-2 PSI

ive often thought about running a duckt from the air-conditioner, but running the ac takes power away and would probably balance out and make no more power.
i would just make some kind of ram air intake, and make some sort of ice box to run your intake through

As soon as someone convinces me that they have an electric motor that can supply enough air to overcome the electric power needed to generate even 7 or 8 psi I would remember you can´t create energy, and you would need one heck of a blower motor to generate a 7 or 8 psi boost at high rpm. just the weight of the setup would most likely offset the gains. on the other topic, as air expands the temperature of the goes down. so releasing compressed air will cool it down. oh yeah, some fire extinguishers are co2. carbon dioxide does not really support combustion, actually it stops it.

Ahhh....FI with a leafblower. Wow, this is going to take aim by haters of ghetto-engineering and Message board haters.

Okay electric fans, leaf blowers whatever the case might be...probably wont work. If you could find an electric motor that could get rpms that high, you´d more then likely end up with a dead battery and an alternator going out all the time (not an easy change in a GT).

Now back to compressed air. I too thought about it. It would take some pretty hard control logic but could be done. Even like a little 10lb take would work pretty well. But you will need increased fuel flow and timing control. Lets say you could figure out a way to only get about 5psi into the manifold, you could increase fuel with a fuel pressure riser and a new pump. So fuel would be easy. Timing could be easy too. Boost sensitive stuff like an MSD BTM would be great, but honestly you could do it just by running retarded all the time. Still...it would be a cheap way to get some boost for a second, it woudn´t be limited by rpms or anything. And unlike N2O its cheaper to refill.

I thought of the concept about 3 years ago and my research into the topic led me to actually just turbocharging my car. I´m really hoping that I can still figure out a way to do it....because it would be the answer to turbo-lag. I just thought it would be something different and a good clean air alternative to N2O.

Yeah CO2 isn´t a good idea. H2O would even be a better idea, just because under high pressure it seperates and becomes combustable. ---burns clean too

H2O is water. yes.
Siragan, I´m pretty sure that when you compress air it gets hotter. The reason being when you compress air you´re stuffing the same amount of air into a smaller area, creating more air molecule collisions and that causes friction...which creates heat. Friction is also why your brakes get hot after hard use. Using an intercooler on a turbo´d or supercharged engine keeps the compressed air as cool if not cooler than if the same engine was normally aspirated. I´m sure that engines don´t "bleed" off the extra heat at a sufficient rate to keep the engine from knocking/pinging.

Different gases will react differently to temperature variances.

Here´s a new idea... Since we are talking about releasing compressed air into the engine like Jason was talking about, would it be possible to take a small air compressor like the ones used for air ride suspension, have it build up to like 100 or so PSI and then have a hose purge it into the throttle body in the front of the intake? Would it have a similar effect to NOS but also be an unlimited source?

JUST A THOUGHT

Hey Type,
That would be forced induction but 100psi would be a little high. In fact the most I´ve ever heard of a stock internaled BPD8 holding is 30psi and that´s Dave Lazier and he has it in a MX3. Heck I´m hoping to hit 14psi safely.

You could do that but you´d be bleeding pressure so much the compressor wouldn´t beable to keep up....you do realize that a turbocharger is just an air compressor that´s powered by exhaust right?
