translate dri laman web indon tu..

Theres much talk about building a boost bottle. Id like to get some input. When building a boost bottle it seams in general most people have stated that the bottle should be built to the size of your engine. So if you have a 26cc engine the bottle should be 26cc in volumn. Some believe it should be slightly larger maybe 2cc others dont. But my real question is when your building the bottle do you take into account the length of the hose. For instance 12 inches of 1/4 ID hose is approx 9.5cc.

So do I take that into account when building the bottle and reduce the size of the bottle by 9.5cc to acomidate the hose. I purchased a juice box in the past for another scooter I had and did measure the volumn. That particular juice box was for a 49cc engine. The volumn was 49cc when I did check it. But the Juice box is part of the manifold and doesnt require a hose to connect the two. Thanks in advance for any and all input

What is a boost bottle?

The boost bottle is a small sealed chamber connected to the manifold of a 2 stroke engine by a small tube. It works with a 2 stroke by when it sucks in gas, then the piston goes up the gas wants to keep going forward but hits the piston. It would then usually go back into your carb making your fuel mixture double rich in the time fractions of a second. With a boost bottle this flow back of gas goes up into the bottle and compresses itself to do inertia, it will then shoot back down into your cylinder. This makes gas go into your cylinder quicker, allowing for a better explostion and quicker stroke.

How to make one

You want the boost bottle to be greater then the cylinder volume. IF its a bigbore rc 25.4ccs you should make the bottle to be around 27-30ccs, not to much bigger then the cylinder. The bottle should be positioned above the intake manifold so that it drains down; an incorrect position of the bottle below will cause air/fuel sepersation and form a puddle of fuel over time.

If your going to make one, drill the intake manifold and put a 1/4in barb in it pointing upwards (you got have a drill and tap if you want to do it right, not having it ghetto with jb weld or something. You can really make it out of anything. I wouldn't recommend using pvc pipe because of gas. But you can make it out of pipe fittings, or even possibly butane bottles just something that is sealed all around. You don't want to have any air leaks. And use a 1/4 in fuel line, I would use pipe clamps around the two barbs(like what airfilter use to hold it to the velocity stack.

How a boost bottle improves performance
Written originally by: SRE

Air rushes thru the carb on the intake cycle. Ignition accelerates the piston down closing the intake port. The momentum (Intertia) of the air has to go someplace, it goes back thrue the carb causing a double rich mixture. The result can cause hesitation.
Due to the velocity of the air/fuel mixture through the carb, we need to take advantage of this momentum/inertia energy. The boost bottle provides a storage tank for pre-atomized air/fuel mixture. Now when the piston moves up towards TDC (top dead center) the boost bottle assisits in filling the cylinder with preatomized air/fuel mixture for a fraction of a second until the carburetor venturi gets enough velocity to fully atomize the fuel.

The boost bottle provies a "BOOST" supercharged effect to each cycle. The advantage is that it brings up the torque and horsepower in the lower RPM range.

Supplies:
Bottle of some sort
6in of 1/4 fuel line
2 1/4 in barbs
Drill and Tap
Some brains

What I experieced
I noticed when I was warming up my ped after installing it was quicker throttle response. When I got it running how I like it I had it tuned a bit richer on bot L and H. I noticed a lot accel power. When I would rev it a little in the air and drop the back tire to take off it didn't hesitate like it did prevously. A buddy of mine dj jon, that had been racing for meyer a while back and owned his own shop for a little while years back said that that thing had crazier torque that he ever seen. He said it was like the old reed motors that he use to mess with. IDK what there called but a couple sponsers^ use to sell them.
