Default Nitro Boost Bottles???

Is it just me or does this seem to be a bit excessive with the Nitro cars?...not to mention illegal.

They don't do much anyway.

They COULD be legal, but only if you had so little fuel line that the volume of your tank, line and boost bottle met the required limit.

It IS a nice carbon fiber sticker on it, though.

Default Illegal?

Ok, How could they be illegal, all they do is expand the crankcase capacity of the engine, all it is is an empty vessel.

they go on the fuel side, right?

if they go on the fuel side, they increase the potential fuel capacity. According to ROAR rules, maximum fuel capacity (including lines and tanks) is 75cc.

If you put it on the pressure side it won't have any effect other than to provide a small amount of volume which would actually even out the pressure pulses a bit.

No they dont, a nipple is tapped into the crankcase and that tube only runs from the crank to the bottle increasing the crankcase not the fuel capacity, the pulsing you are refering to is a fuel issue but caused by the small crankcase capacity of the engine by increasing the crankcase capacity you rectify the pulsing.

PS; I had one guy try to tell me they are full of NOS

you've got to be kidding. tapping a hole in the crankcase? Holy cow - who would do that? What would be the benefit of it?

If that's such a good idea, what ever happened to the turbo backplate thingamajig? Wasn't that on the same principle?

Default Boost Bottles

Years ago Dirt Bike Magazine tested all the available boost bottles on a dyno and on various size motocross bikes, and thier finding was that the boost bottle did absolutely nothing on any machine displacing less than 490 cc. It was a fad that quickly passed and faded from the motocross scene. It is possible that they do something on an RC Car other than looking cool, but I have yet to fugure out exactly what that might be.

Default Blow-off valves - is it possible?

Do u think its possible to use the pressure line on a nitro engine and have a blow off valve somehow by using the pressure inside. HMMMMMMMMMMMMMMMMM that would be sick. Does anyone know how a real blow off valve works?

no it isnt possible or its a waste of time
a real blow off valve lets the pressure out of the inlet manifold when you change gear in a car.
