OK so I've got this rep of being the Ghetto builder, and I was tinkering with a desgin thats been on mind for a while.
So the problem with running boost is either the installing all the compnets and everything right?
Superchargers on J-Body's only come on the Quads not LN2s right?
The electronic superchargers/turbos are stupid and don't work unless you run a system that costs more then the car and needs like 3 batts. right?
Well I like the idea of having a turbocharger ran off a power source that the engine, so I was looking into the idea of making a way to spin the turbine of a
turbocharger inducer side. After hours of research and physicaly making a few, I've found that to make at least a few psi (2-3) you need the eqivulant of at least 1 horsepower in a motor power source to spin the turbine per psi.
So I was at my mothers house the other day and seen alot of broken weed wackers laying around.........
And BAM it hit me the weed wacker is compact and only function is to spin at diffrent speeds, it can even handle a bit of force slowing it down.
now I'm getting into building a system that can mount this into the engine bay (removing the stock air box and maybe relocating the batt. to the trunk)
and someway linking the throttle linkages of the two throttle bodies together.
So when you give it some gas it speeds up and when you back down it slow down and lowers the boost just like a normal turbo with the LAG!!
So one thing I will have to think about is the noise made from the weed wackers engine:
maybe routing the exhaust system down and out the engine, and in-casing the motor in some kind of box with sound deadner.
I can't wait to get at least the compresser and wheel hooked up to the weed wacker and see what kind speeds it spins at and if it makes anykind of boost/how much air it can move.
I'll be getting back to the work and I'll let you know what I can come up with.
Let me know if you have any thoughts, or ideas to improve the system!!

So, if I'm reading what you wrote correctly, you want to use the gas engine from a weed wacker to spin the compressor wheel of a turbocharger/centrifugal supercharger?
It's a neat idea, and I know you said at least 1 hp but I guarantee it will take far more than 1 hp to sustain positive pressure on this large of an engine. If that's all it took, then centrifugal superchargers would be as standard as a camshaft on engines today. It might take 1 hp to spin the impeller 65k+ rpms, but compressing the air is another story.
I have no signiture
theres a vid on youyube of some guys puttin a backpack blower to a ranger on th dino and it showed gains. lol
Just buy a centrifigul supercharger.
My question is would it really be cheaper to make this work even compared to the most "ghetto" turbo set up?
No matter where your boost is coming from, you still need an upgraded fuel system and tuning.
Also keep in mind that most gas powered weed wackers are two cycle engines, so forget running them off the car's fuel source.
Next - all but the most heavy duty units are pretty weak. Yes they can spin some RPMs, but when they encounter resistance, they stall out..
The next dillema is once its all hooked up and installed, how do you plan on throttling up the weed wacker engine? I'm sure you could work up something like an ITB set up, but that adds to the cost.
Not trying to hate, but as a whole complete project, this wouldn't be cheap and it would be a pain in the ass

On a side note, I agree with Whalesac. Thats why the electric ones suck as well. Electric motors make good numbers in HP and especially torque, but still don't have enough steam to make PRESSURE. They can move air like crazy, but not pressurize it. I've looked into this stuff too, as I'm very cheap when trying to tune up a cheap car. I always wondered how it would work if you had a tank of compressed air that you periodically filled up at gas stations or at home and had some type of electronic regulator; just incase you wanted another idea to pursue. Good luck though, I look forward to how out of control this thread gets.
"In Oldskool we trust"
I just want to see you start your weed wacker motors and then your car. That in itself is funny to me.
o wow... this is gunna be very interesting no matter what the outcome... subscribed
for the amount of work needed you could just buy either a GMPP s/c kit and create more power or build a turbo kit.
or just build an n/a motor, run 13's and be done with it.
i understand the want for something different but a j-body boosted is different. that should be enough.
Trailer Queen corvette wanna-be with 40 coats of wax and powdercoating that soaks in.
Do you realize how many RPMs the turbine needs to spin?
219whp - I <3 whine
I didn't know weed whackers spun at 100,000+ rpm
Just to be a smart-ass:

I didn't know the weed-wacker engine and the compressor wheel had to spin at a 1:1 ratio...
However, this idea seems fruitless, a standard turbo kit would be easier and probably even cheaper.
fortune cookie say: better a delay than a disaster
o god i didnt realize this was the umods guy.... lol this WILL be interesting... which kit will this go in btw? pro? street? race?
give it a go and report your results....
Skip a whole bunch of superfluous fabrication and duct tape a leaf blower to your intake.
Make sure you install some sort of throttle control for the leaf blower. Or just Google the phrase
"civic leafblower" and realize that somebody has already beat you to this horrifically moronic idea.
[Your scheme] is so lame and played out that i laughed much harder at JO3Y's picture than
I did after reading the first post. THANK YOU for this! YOU WIN!
ZZZZZZZ
Chapparal built a Can-Am racer in the early '70s that used a 2-stroke engine to turn the fans that sucked the air under that car body (It also had spring-loaded skirts that contacted the ground!) to help create down-force, in hopes to aid handling. It worked, but the 'stroke engine failed mid-race. Still, a lot was learned thou....
Don "Big Daddy" Garlits played with a compressed-air tank to force air into the engine of his top-fuel dragster's engine, as opposed to using a supercharger, in the early '80s. The tank was as large as the entire area under the skin of the front of the car, and took forever to refill. Not to mention that as the tank exhausted... the manifold pressure level dropped.
Wynnjammer made a centrifugal blower for the S-truck double-deuce, try adapting that... if you can find one.
Go beyond the "bolt-on".
HOLY @!#$ I JUST GOT A GREAT IDEA!
I was at my mom's house just the other day (I also live there...), and I was making myself a badass protein shake and it hit me! What if I use the motor from the blender to boost a weedwhacker? Now I figured it out and I'm going to need atleast 500watt blender to make this work. I'm going to go out to my dad's garage and hook up a bunch of blenders to see which one looks to be spinning fastest. Only problem is this thing will be so powerful I won't be able to put it to good use.
Anybody know of something I can do with a super powerful boosted weedwhacker?
