what gets me is all these people goin along with it. superchargers working on 2 strokes is like people saying gravity is not real or the sun revolves around the earth. it has been proven and you can show someone how it wont and cant work.

won't work to any significant gain, you'b be better off paying $70 and getting adam at AB mods to do some of his tricky finger work to your internals, for $25 it isn't bad though.

I think it's running lean with that extra air being pushed in.

Dude check this out don't say anything is impossible.

Conventional Two-Stroke
Dirty and Inefficient

The title may give this away, but if your auto mechanic were challenged to a word association game, and the first suggestion was "two-stroke engine", the likeliest two first answers would be "dirty" and "inefficient."

This is because, for the last 120 years, almost every effort to improve engine efficiency has been expended on only four-stroke engines. The results are commendable; top of the line four-stroke engines have reached the zenith of their potential. Only by supplying the cylinders with pressurized air, as is done in either super charging or turbo charging, can efficiency be increased.

Looking at such four-stroke engines, you have to wonder why, since the air is pushed in, air still needs to be pulled in by an intake stroke. Once you push the air in efficiently enough, you should consider using only two-strokes, which doubles the number of power strokes. A LIM type engine, even with a slightly shorter power stroke, can make up to 90% more power at a given rate of rotation (rpm). With this system, smaller engines can do the work of larger engines, and at lower rpm, with less friction, fewer parts, lower fuel consumption and longer oil change intervals.

Those two words, "dirty', and "inefficient" are the magic words which have deprived the world of the valuable benefits of two-stroke technology developed for the twenty first century. LIM Technology, LLC., located near Baltimore, now offers the next meaningful step in engine development: a clean, powerful, yet fuel conserving system, in which supercharging enables two-strokes to operate as cleanly as four.

LIM has two prototypes which have already run, and which can be displayed and demonstrated on little or no notice. These are supercharged two-stroke engines with patented, and patent pending, features. The testing to date indicates that even with some of the latest modern enhancements which are now off the shelf parts in four-stroke engines, the cost of making an engine, buying an engine, and operating an engine would all be less.

The next prototype is being readied for testing and demonstration in a car, which is expected to be road ready this June.

Lower fuel consumption will enable lower pollution. Lower fuel consumption will extend the life of the world's petroleum reserves. And of course, lower fuel consumption will save owners of LIM type engines tons of money.

By investing in LIM in its first, and probably only and final, round of capital solicitation, open only to accredited investors, you would be justified in anticipating unusually large returns, once industry adopts LIM's break through technology.

Early adoption is to be anticipated because the cost of production of a LIM type engine for any given task is going to be about thirty to forty-five percent less than a conventional engine designed for the same task. There is lots of room in those savings for significant royalties.

the only way to make a two stroke more efficient and use forced induction effectively is by using direct fuel injection (which i'm sure these high tech turbo charged two strokes are ) and to use a power valve system (a valve in the cylinder head for the exhaust, which instantly gets rid of the less friction in a two stroke advantage) to allow the exhaust to open before the intake to allow scavenging, and close before the intake to allow it to build pressure, all of which have been done before, and of which have been deemed less efficient then comparable 4 strokes except in very large scales (ship engines), Yamaha uses a similar system in the two stroke in there jet skies except they still use loop scavenging in conjunction with electronic fuel injection, but it still isn't as efficient as there 4 stroke snow mobile engines, and on top of ALL of this, no glow engine has electronic fuel injection, or a power valve exhaust, and no computor to calculate the amount of fuel the for injectors in inject into the cylinder, so makes it a pointless discussion for here and now.

god i don't know how many times i have to say that for people to get it, on our small scale engines, you will not see any gains from forced induction that cannot be gained from doing a little port work.

I was replying to snoking 16 he said:what gets me is all these people goin along with it. superchargers working on 2 strokes is like people saying gravity is not real or the sun revolves around the earth. it has been proven and you can show someone how it wont and cant work.
As you can see he did not say small scale I just wanted to prove you could supercharge a two stroke. And I completely agree with you model engines and superchargers go together like water and oil they don't mix. I do find it amusing that Brent is having a result because no matter how you spin it he is getting more power. If he was leaning out you could hear it when he lets off the throttle it sounds pretty well tuned to me.

yes you can supercharge a reed valve two stroke.. but our engines its worthless... it might as well be a wind tunnel .. no one said a 2 stroke couldnt be supercharged.. dude said in reference to our engines im quite sure.. point is.. kids buy the gimmiks up like crazy so these companys keep ramming them out..

snoking16

ok.....hows this, SUPERCHARGING A CONVENTIONAL 2 STROKE ENGINE WILL LEAVE YOU WITH NO PERFORMANCE GAINS!!! if you guys knew how these little engine really worked this thread would be dead by now. im done trying to convince people. its common knowledge. if they worked then every single two stroke would come with a supercharger on it. just like 99% of any diesel engine out there come with turbos. they work so good that they come from the factory like that. even superchargers for 1:1 scale cars are bad for the engines they take thousands of miles off the life of an engine. if you search supercharger in these threads you will find thousands of people like me trying to help others by informing them that superchargers are a waste of money and can harm engines.

ttoks

snoking i'm not trying to cause an argument here because believe it or not i do respect your opinions, but jesse and turbot are right, there really isnt any conventional two stroke, there are just as many power valve two stroke out there as there are reed valve, two stroke and disk two strokes, we all just need to learn to get along really.

RCCanuck

I think it is simply adding more dense air to the carb......so in reality its just leaning it out....it may be that it is set way rich whitout the RB part on.....What ttoks said makes sense as well it may be adding to the scavenging affect on the 3.3 making it run a little more efficiently

drag racer

i think the only reason things things are still on the market is because of noobs buying these up without researching them at all. or they buy them for the wow factor, so they can say they have a supercharged rc.

Sweet! Those LIM guys are pretty much putting scaled up supercharged versions of our engines in real cars!!! I like there ideas on improving the enviroment and just about everything else. I really hope their 2-stroke idea pulls through because I don't want to see 2-stroke engines go. In some states 2-stroke dirtbikes are illegal and they are trying to get it nation wide... it is thought that in the future companies will be forced to stop making 2-strokes.

BRUSHLESS BASHER

That's only California as far as I know, and it's only illegal to sell them, not to ride them.

DriftingDragon

any 1 have a link to the nitro supercharger

DriftingDragon

its cause they have bad exhaust

BRUSHLESS BASHER

Bad Exhaust ROFLMAO[sm=lol.gif].... please excuse me while I laugh some more[sm=lol.gif][sm=lol.gif][sm=lol.gif][sm=lol.gif][sm=lol.gif][sm=lol.gif][sm=lol.gif][sm=lol.gif] What on earth would make you think that? What could the exhaust have anything to do with it? They were outlawed because of emissions, you aren't even allowed to own a gas powered lawnmower in California.

ttoks

by bad exhaust i think he meant be exhaust gasses... they burn oil which doesn't exactly make them very clean in terms of emissions.

DriftingDragon

like awhile so they are getting more strict about emissions

so any 1 have a link to the nitro supercharger?

ttoks

i wouldn't bother with the RB innervations supercharger seriously, you will have to make you own mounting braket, for the same amount of work and less money you could buy a dermal and a pointed carbide cutting bit for it and add fangs to your piston sleeve and get the same result, or spend $110 and send it to AB mods and get the 3.3 making .21 big block like power.

DriftingDragon

im gunna be putting it o my mt2 g3.0 when i get it

ttoks

unless your getting it for 25 bucks you'd be better off giving AB mod 110 bucks to do his stage 2 mod's to your engine then paying the $150 RB innervations ask's for there supercharger, regardless of what engine it's going on.

DriftingDragon

would it be possible to find 1 off of an old rustler? or stampede i can remeber wich 1 had it

ttoks

if your going to buy a supercharger at all, look into the one made by O.S for there 4 stroke plane and heli engines, it is a proper supercharger, very well built.

DriftingDragon

ok but will that work on the mt2?
