How Does A Boost Bottle Work?

Comments: Hi, I was curious about the MIP boost bottle for the nitro vehicles, do they work? if so how?

Response: The way a high performance two stroke engine is designed causes it to send unburned fuel the opposite way through the intake of the carburetor at low to mid range RPM's. This reverse flow of fuel causes restrictions in the flow of useful air/fuel mixture and makes the engine run poorly.

A boost bottle is a chamber that allows the reverse flow of fuel a place to be stored until it can be used by the engine. All it does is act as a little storage cell for fuel. This will help smooth out the power band of your engine by removing this unused fuel from the engines crankcase and carburetor.

Note, a boost bottle will not increase your engines output. It is simply used to smooth out a rough idle and mid range that is very common with small 2 stroke engines. You may witness a slight increase in fuel economy with a boost bottle since it recycles fuel a little more efficiently but there is not a huge difference.

It seems as though a boost bottle is used mostly by serious racers that require a very smooth power band. Most backyard hobbyist would not appreciate the benefits of this upgrade and their money could be spent on more useful upgrades.
