Duct fan equals homemade super charger

[Spiderweb]

This is a seriously odd post I know, but I wanted to get some help with an idea that I had.

To start let me explain what it is that I want to do. I bought this dune buggy recently with a 250 cc motor on it. I was looking at aftermarket parts and noted that they have all sorts of things to boost power, but nothing like the supercharger on a car. I looked at an electric model charger on the web that boosted HP by 30. Now a 250cc engine is roughly around 15 HP so I am guessing that a Super Charger could give an addtional 2 to 3 which is alot on such a small engine. I need more power :)

My idea is to make an electric homemade super charger for my buggy. After searching the web, I located one designed for a Mini Cooper. It was much to large for my idea, but I did note that it resembles the duct units on model aircraft. This Mini cooper designed charger put out 2psi which boosted 30hp.

The ideal duct size is around 2 1/2 inch, but I can reduce it a little if need be.

Now my questions are as follows.
1. Do they make a duct fan and motor that runs off a 6 volt system?
2. Do you think this thing will over heat my engine?
3. Do you think I am nuts? :P
4. What are my varibles when attemping to do this?
5. Does anyone have a old setup they might be interested in parting with cheaply so I can test this before I spend serious money on the attempt to make a better system? I need something with some pretty decent air output.
6. Do you think this will work?
7. I do not know alot about the force these things are able to make. Does anyone know of some good sites with the proper info on the pounds of thrust various props generate?

Alot of stuff to know and I hope someone here is a rocket wizard and can help me out. Thanks alot ahead of time and please feel free to email me at anytime at spiderweb@sledgehammerproductions.net or MSN handle Spiderweb@keywaves.com I look forward to hearing from you.

I used to work on snowmobiles(2 stroke, usually less than 600cc). In my own experience, if you want more power, it is usually simpler and safer to change out the engine. I was able to pick up a 440cc polaris engine(free air) for about 50 bucks. I am just saying this because if your not carefull setting this up, there will be problems.
Second, I don't know if you have worked on engines before or not, but after fitting it out with anything that changes the intake stream, you will have to retune the engine. You will also have to adjust the timing in order to get the most out of the engine, but the ideal spot is usually stubborn to start the engine with.
On overheating the engine, it all depends on the engine design, ambient temperature, carburetour settings, ignition, and several other factors. If you do it, just put a temp sensor on the cylinder head and have a meter up by you so that you can keep an eye on the cylinder temp.
As far as the "Do you think I am nuts?", no I don't. I used to see how much power I could squeeze out of small 2 strokers on snowmobiles.
Will it work? It all depends on the setup that you use and how you tune the engine. It might or might not give you the boost that you are after.

The best advice on this, Be carefull and have fun. If it works, let me know.(Always looking for a way to sqeeze a little more out of my 292cc single)

if you want a supercharger on it use an automotive smog pump, search the web for smog pump super charger and you will find tons of people that do it but, to be perfectly honest...its a pain in the...................

if its a 2 stoke engine on the buggy, forcing air into the cylinder will do nothing. it wont help bottom end, it wont help anything. If its a 2 stroke engine, look into tuned pipes for it.

now if the engine is a 4 stroke, thats a different story, but I dont know jack about FI on a 250cc engine. im sure the carb is going to be a problem.
