Performance 80cc

i still think it's a pretty good idea, but i have no idea how it would actually work.
i think it is possible for it to add some amount of power, but not a whole bunch.
I don't think it would make an 80 c.c. engine run like a 200 c.c. engine.
but, anything is possible and as long as the turbo is sealed, as well as the entire intake tract, adding compressed air to any engine will make more power.

but i am a little confused on how it would work on a 2 stroke because the fuel-oil mixture goes into the crankcase before it goes into the cylinder.
so would this compressed air hurt anything in the crankcase?
i realize that it would not be like blowing 100 psi of air into the crankcase, but i'm wndering if it could cause any prpblems with the bearings or the gaskets due to too much pressure?
i wonder just how much psi that little blower can put out.
man, i know it's crazy and expensive, but i am very surious about this little thing and i am wondering how well it actually works.
The gear head in me is being curious, and as the search for more power in these engines is ever increasing, a turbo makes a little bit of sense to me.
i wish that someone neutral who actually has one of these turbos would put a video out there telling everyone if it's good or bad.
i still can't get over the price tho....it's too expensive for me to justify buying one.
if it was a lot cheaper, i'd buy one just to see how it would work.
 
Welcome to my world. I've been searching the web to see if I can find one, but no.
If you think about it, would the 80cc be able to spool it up? Isn't the exhaust and intake at the same level? Would you lose all the power every stroke? How much pressure will the turbo spool up? Will it blow the head off? So many questions!
How about;
Electric blower motor forcing air when you flip a switch?
H2O fogger?
Just some food for thought.

yes, the intake and exhaust ports are at the same level on the cylinder. you woudl have to custom make an exhaust to feed into and out of the turbo. you would think that there would enough exhaust pressure to spool the turbo up as long as the exhaust is 100% leak free. having a sealed, non leaking exhaust, and a sealed, non leaking intake would be partially the key to making this thing work. you would need every ounce of exhaust getting into the turbo to spool it up and every ounce of intake air getting into the engine to get any power.
in theory it would work, but i am still curious as to the effect of the compressed air going into the crankcase before it goes into the cylinder.
i'm thinking that it would be fine, but would that take away from the effect?
you need to cram as much air into the cylinder as possible with a turbo, and by the air going into the crankcase first, would it have the same results as if it were going dorectly into the cylinder?
curiosity is getting the best of me, and if i had a couple hundred $$ laying around collecting dust, i'd just buy one and see how it works on one of these engines.

good point.
is is possbile that this little turbo would make enough boost pressure to blow the head right off the engine with the stock head studs?
an electric blower motor would probably not work. it would need to put out A LOT of air, and it would need to be in a totally sealed set up to gain anything from it. a blower motor can move air, but it can't create compressed air unless it is in a sealed case or something. if there is a way to get the air compressed, you would need a pretty big blower motor to get any effect out of it in my opinion. this is why the compressor wheel blades are shaped like they are in a turbo the shape of the blades, the number of blades and the sealed case is what compresses the air.
after all a turbo is just an air pump, but the way the compressor wheel blades are designed is what makes it work.

H20 fogger? (H20 is water)


this is crazy!! we are tallking about a turbo for an 80 c.c. 2 stroke...we have too much time on our hands! :)

Way too much time!
I'm planning on building this bike and taking it to the Shriners Temple for an auction. All the proceeds go to the Shriners Children Burn Hospital. Now with that in mind, I'm going to call the company that makes the turbo(or the dude who is selling it) and see if they could donate it or give me a good price break. hopefully that will work.

With the fan, look at it this way;
When you go to the drag strip, make a couple of passes with no wind, you have average time slips. Now you have a head wind, your forcing more air into the carb(not much, but enough), your going to shave your time down. So your picking up a little HP, MPH and helping the MPG. Not much, but a 0.01 will win a race. Its like a K&N cold air kit, with a fan.

:unsure:H2O fogger(injector);
Your atomizing water, say 1/4th of a teaspoon. mix that with air and fuel(heat), compression, you have a steam/fire explosion(in theory). Im still working on this one. Im going to try it out on the lawnmower first.
:cry:
 
oh ok, so you're talking about water injection. i thought you typed it in wrong, and you were trying to refer to nitrous oxide (N2O).
they did make water injection kits for v-8 race engines a long time ago, but i have no idea if anyone still makes them, so, in theory it can work and is supposed to help stop pre-detonation in the cylinders.

you're referring to a ram-air effect (like on pontiac gto's) and it does work. the key is cramming as much cold air into the intake as possible, but i'm not sure how a fan would work. any time you can reduce the temp. of the intake air, you will build power. cold gas and cold air going into a hot engine will make some more horsepower.
 
Well I think I am close now. I have all my parts except for the rims, and they are the most important part of the build:confused: . So....I need to save a couple three hundred for Surley Large Marge rims.:D

I have a few of questions about the 2 stroke;
Difference between the carbs?
Where do I get a USA 2stroke?
Are they that hard to tune and keep running?

I have been reading alot of the posts and its alot of; "it wont do this", "its doin that" and alot of "I cant...".
Is there a Forum that has "POSITIVES"? :unsure::unsure::unsure:
 
RC nitro ignites very easily, but detonates like mad. you DO NOT want to run nitro. just dont do it

I've run nitromethanol in a few small two stokes before, it eats fuel line made for gas (just as gas eats silicone line)

it does not require a lot of compresssion at all, I can get a weedeater engine to diesel on the stuff (run with no ignition when hot)
 
I don't want to be negative but there are just some things that will not work. Simple laws of physics prevent you from ramming air into the engine through the carb. These carbs all need vacuum to draw fuel up through the metering jets. If you have enough pressure you will shut off the fuel flow from the carb. With a scoop on the air cleaner you probably won't get enough air to shut off the fuel but you will lean out the mixture. This will give a small performance boost but at a cost. (lean=heat) Heat will kill these engines real fast. Another problem with the turbo that I see is with a 2-stroke engine you do not have a pressurized oiling system. Without oil flow through the turbo, it will fail almost immediately. But hey, best of luck with your project. I would love to be proven wrong.

wow, i never thought if that!
a turbo needs pressurized oil to feed the bearings, and without it, it will lock up in no time.
