Custom ehhh I guess supercharger....
Ok, heres my idea, do a custom I guess supercharger with approx. 2-3 psi, using this: http://www.horizonhobby.com/Products...source=froogle
except a high performance version of that, and some tubing, and at the same time make a snorkel. Let me know what you think.

thats never going to work. your engine will pull more air than that can push. all that cheap fan will do is bog the engine down.
a lawn mower, you may get lucky with

hmm
Well Im really into hobbies, and with the right setup these ducted fans put out 10-12 lbs. of thrust, the motor I will be putting on spins at 56,000 rpms. Not a cheap 11.11$ one, so What I am saying is I'll be looking at approx 500$ into this. Not 12$

Ok, there is one core problem, voltage, it's too low. I posted this in another thread but I'll repeat it here.
This electric supercharging can work. My little brother shoved a leaf blower into the intake of his Civic on the dyno and got 40 more HP. In fact, at sufficient voltage it's more efficient than belt driven superchargers. The reason the voltage is an issue is that at low voltages high current is required to make sufficient power. (power = voltage X current) Resistive losses are a function of current. If you had the voltage bus of a typical hybrid, (200+V), you'd be good to go. My friend did his master thesis on this very subject so maybe I'll get a copy of it and can post more details.
Now, if you wanted to race and just dump some high end lead acid batteries into an electric super charger for the 1/4 mile you could get a car to go fast. However, trying to pump adequate amperage from your alternator to power sustained boost is probably going to be a net loss.
I don't want to discourage you, I just want to make you aware of some of the challenges you'll face. If you can solve these issues and make it work that would be awesome.

well heres what Im looking at
I am looking at upgrading my alternator to the best one I can find, was planning on this before I even thought of this due to all the lights I am going to be adding when I finish my lift, so The highest one I can find is 190 amps, which I think is low, I'll keep looking, but with a brushless motor, from novak, (rc car motor) it will draw a lot of power, but what I could do is get 2-3 yellow tops and just have an on/off switch and turn it on and off whenever I need the power, so my question is, would it be worth the time and effort? I have everything I need except the duct, Looking for an aluminum one atm, because the motor is so powerful it rips the plastic ones to pieces.

As stated above, it can work. You need a big electric motor, like a leaf blower.
At 12v the amps required to run that kind of motor are huge.. Like in the scale of 100-200 amps.
Might be able to run it part time, beyond that - good luck...
We're talking - best case - 2-3 psi.
Don't confuse thrust with CFM or manifold psi.

well of course
Ill stick with hobby motors because I can get the high performance versions of any size motor I need, the the problem becomes, If I get a huge motor then the air flow around the motor (seeing as it will be inside the intake pipe) will be restricted, so then if I go with a smaller motor I should be fine, and I am testing the motor right now on a spare yellow top I have so far its been running at full rpms for 35 minutes without even showing a sign of slowing down.
The other thing I could do is just make sure I don't drive to far away from an outlet and just show off my power with a 100ft extension cord

it does, guys seriously do some searching on this website and you will find more supercharging/turbo/whatever threads than you could ever need. the general consensus is that boosting this engine is pointless because its still choked at the VAFM, it has one intake and one exhaust valve per cylinder (undersized at that) and the headgasket plague also. i'm not trying to discourage, just making sure you know what you're getting youself into. personally i'd love to see something work

the VAFM and TB are sized about the same, so getting rid of the VAFM isn't going to gain you much without addressing the TB.
Forced induction is the only cost effective way of getting a 200hp 22RE and keeping it's driving manners.
I've seen dyno runs of 180hp 22RTE (rear wheel) - stock AFM, stock ECU, using a nice Garrett ball bearing turbo.
I do RC stuff too, I still don't think that the "hobby" motors are going to work.
You're welcome to prove me wrong, however!

One thing about the VAFM, it is a choke point but FI will still flow more air through it. Differences in pressure is what causes flow. FI will create a large difference in pressure.
Like I said, a leaf blower produced 40 more dyno verified horsepower in a 2003 Civic. However, as stated you need a motor with that kind of power.
Now for intermittent use, you bet this will produce more power. Sure there are other options like nitrous which might be easier but there is a fun factor in integrating a system like this. You can experiment with how much continuous duty your charging system can handle too.

ok, kinda off topic, but isn't the point of the VAFM to regulate how much air is flowing into the engine. ie, regulate how much air is going into the engine?? I've always been kinda fuzzy in that area, so i'm just stating what i've observed.

just need the amps.
Ok the top end yellow top puts out 900 amps. This translates into a lot of power for that leaf blower. Now if I can mod a semi alternator to fit then I am set, I am going to pick n pull tomorrow hopefully to see if I can just see how big it is
