****HOW BOOST BOTTLES WORK ****


As the engine draws fuel and air in through the carb on the intake cycle, the spark plug fires this mixture forcing the piston down and sucks a small amount of air into the carburetor for the next intake cycle. As the piston and crank bottom’s out on the bottom of the cylinder, the piston begins to make its return upward. As this cycle is happening, the piston pushes air back through the carburetor naturally under pressure. This action creates a reverb effect and causes the air / fuel mix to become double rich as by now it is processed TWICE by your carbs fuel jets. Most commonly, this results in rough idle, hesitation, bogging, and the ever-so- frustrating: Sputtering at top end. The reason the sputtering and bogging is happening is because of the double rich mixture. Heavy exhaust smoke, heavy engine loading is often looked at as too much oil / fuel ratio, bad carburetor, etc. While this may be one of those problems, it often is not. Your engine is actually choking itself out with a bad fuel mix! The installation of our Boost Induction Systems™ Boost bottles eliminates this nagging problem. (Hence the location of the inlet) Our Patent Pending Internal Metering System™ Automatically adjusts itself to work with your engines compression and carburetor. Our bottles will eliminate the reverb caused by your pistons return to top dead center (TDC) and remove the double mix! Now, with the bottle installed, operators are now no longer fooled by the double rich mix. This now allows proper adjustability of the carburetor! Tired of sacrificing top end speed for low end? Or low end speed for high? That’s because you have a double rich mix.You cannot have one or the other without a proper intake booster (Boost bottle).


WHAT ARE THE ADVANTAGES OF A "DUAL" BOTTLE KIT? WHY ARE 2 BOTTLES BETTER THAN ONE?


This is a great question. Having 2 inlets on the manifold doubles the passageway for both the rising pressure of the cylinder, and the other inlet for the downward. They will both work together to smooth out the incoming airflow and add a substantial amount of power rather than just one bottle alone. While a single bottle kit is VERY effective, the Double bottle kits are demanded by the more savvy engine builders, and competition racers whom have upgrades their engines and are going for the "Elite" in horsepower, torque and RPM gains rather than just a recreational hobby enthusiast.


WHAT IS IN THE BOOST BOTTLE AND DO I NEED TO REFILL IT?


No, you do not need to refill the boost bottle as their sole purpose is to even out your fuel mix and apply the right amount of pressure to let you carburetor breathe better. Once your boost bottle is mounted on your engine, please do not remove it. It will outlast the life of your engine and can be transfered from one engine to another for years to come. It does not need to be refilled.


Is this true and if it is would you have to retune your carbretor???
 
I have read mixed reviews of people that Like it and people that say it doesn't make a difference. Personally, I don't have any experience with them. Just saying you may hear some mixed reviews so go ahead and get one and let us know if it works!
 
I did a little research on this and haven't come up with a conclusion if they work. From what I have read if you do a boost bottle you want the bottle, hose, nipple to total 1 - 1.5cc larger than the CC's of the engine. So a 26cc engine should have 27- 27.5cc total capacity. Too big or too little of a bottle, you'll get no benefit of a boost bottle. I haven't experimented or played around with one yet.

I read up on these. Most positive reviews were posted by users who quickly followed with "ps I sell these here's my website or eBay link". I found multiple threads of people saying they gained no performance whatsoever. There was also a YouTube "mythbuster" done with these and it was found to give 0% improvement. I can't find the link though.


Long and short, from what I've read and seen......save the money
 
View attachment 3643I've got one fitted to my 28.5 its been on there so long i would have to take it off and see if it changes performance. Was fitted to a 23 first and i do think it helped to make it a little more snappy on the throttle.For the gain if any ? would rather buy other mods just my 2 cents.

At one point I was about to pull the trigger on the ADA juice box boost bottle but after doing extensive forum reading it seems like everybody concurs that these are just a waste of money and extra weight. Some guys says it does help reduce the lag a bit (bit better acceleration) but at the expense of upper RPM's. They look cool but I guess that's about it :p
 
Alot of the description does not make sense to me. This is just my opinion based off of a few limited set of articles I've read about 2 strokes and boost bottles that actually seems to compliment each other. All the other documents were off on their own unique theories.


As the engine draws fuel and air in through the carb on the intake cycle, the spark plug fires this mixture forcing the piston down and sucks a small amount of air into the carburetor for the next intake cycle.


This is bass ackward! When the engine reaches TDC and fires the piston is forced downward which creates higher pressure beneath it, therefore, the crankcase pressure increases. When the piston drops low enough the transfer ports will open to the combustion chamber. The higher crankcase pressure will force the fuel air mixture up the transfer ports but not through the closed intake port (back to the carb). There is a small amount that does not go through the transfer ports. Very little of it bypasses the pistol walls and back into the intake manifold. This is what creates the "reverb" they are talking about.


As the piston and crank bottom’s out on the bottom of the cylinder, the piston begins to make its return upward. As this cycle is happening, the piston pushes air back through the carburetor naturally under pressure.


Bass ackward again. The compression/up cycle creates low pressure beneath the piston which pulls air from the carb into the crankcase and also compresses the fuel/air mixture above it. There's no way for the piston to push air back to the carb because the intake port is always closed to the area above the piston. Everybody take their carb off and rotate their engine through a complete cycle. Look into the intake port and see if there's any way possible to push air into the carb on the up cycle.


This action creates a reverb effect and causes the air / fuel mix to become double rich as by now it is processed TWICE by your carbs fuel jets. Most commonly, this results in rough idle, hesitation, bogging, and the ever-so- frustrating:


Double rich huh? Okie dokie :rolleyes: Now I think the seller might have gotten some of the cycles descriptions wrong. It could have been a typo. Who knows.


The one and only thing I agree with them on is that there is a "reverb" or pulsating of the intake charge within the intake manifold. Another bit of information I've read on boost bottle theory is that the up cycle pulls air into the crankcase right? The down cycle creates higher pressure in the crankcase and pushes the fuel/air mixture up the transfer ports into the combustion chamber. Well not all gets pushed through the transfer ports. Some of that bypasses the piston walls and flows back into the intake manifold. This creates a pulsing effect. The call it reverb. Same thing. The additional volume the boost bottles create withing the intake manifold just lessens the effect.


Now with all that being said.... If you really really want to stop the intake charge "reverb", get a reed engine. I think Mr. Trevor Simpson was way ahead of his time by figuring this out. The reed plates basically act as valve preventing and charge from backing up into the carb. The flapping reads also create a #$% load of turbulence which helps atomize the fuel/air giving you a better ignition.

im not saying if they work or not but all my buddies that run 2 stroke quads we all run some sort of boost bottle it might work better for larger cc motors but not sure as to the comment of them being 1-1.5cc larger that the engine mine on my quad are no where near that. but as for what demon was saying as to things being backwards doesn't the crank on a 2 stroke pull the air into the crank case and then one the exhaust stroke the piston goes down and pushed the air+fuel mixture thought the transfer port. that is how i always thought they worked. so it pulls air into the crank one the compression stroke and forces that same air into the cylinder on the exhaust stroke and then repeats itself. so i still don't know how the boost bottles would work only to hold a little more air and fuel to it may force a little more in the engine i am not sure let me know what everyone thinks. and if anyone runs them i would love to here if they work on smaller cc motors
 
I've got guys down here that run em and they swear that they could see a difference. On the other hand I got guys that tried em and they say they didn't do a darn thing. I really should have paid attention to what motors they were running.
 
I had these on my FG, tried one bottle, and tried 2, seemed to not make any difference, accept for the fact that since I put them on I had idle issues.


Pulled them off, truck runs perfect again, so my opinion they are a waste of money, they do look cool though!
 
Thanks E5B


That was quite the video, showing us what happens in a BoostBottle.
