boost bottles

[dirtracer1188]

i have a 01 banshee set up for tt and i have a vito's boost bottle, bored .80 over noleen pipes, reed spacers and 2 k&n's right of the carbs and the throttle response is like my dad's cannondale witch is fuel injected.

thats just good jetting.... not the boost bottle mod

Boost bottle are almost just for the look No HP gain

pretty much

Sounds like a good test for Mythbuster's. In theory the bottle should work, but were talking minimal volumes of air with a slight increased pressure transfered across the system. I can't see a major benefit but I definitly can't see a decrease in power. During the upstroke with resultant suction or neg pressure placed on the intake, there will be less resistance or the neg pressure will be lower v/s no crossover tube/boost bottle. This to me should mean better crank case filling, kind of like running a bigger carb, you have less neg pressure cause of less resistance. Hmm makes me wonder about velocity though. That may be the key right there. Some set-ups benefit from more intake velocity than others. Thogh atomization of air/fuel through the carbs have already taken place but filling pressures could drop meaning less of both for combustion. Where's CEJ when you need him. This may be like some motors benefit from larger carbs and some suffer. Ok my head hurts.

Yeah, what he said

my understanding was that it helps with throttle response, by storing a small fuel/air charge, not to gain any more power. and that won't show on any dyno thait I know of.
