PVC Boost Can Set up Exactly 69.71CCW/Tube and-Ftngs
Note: CID = No. of Cylinders(1) x 0.7854 x bore x bore x stroke (all in inches)
CID to CC"s Conversion multiplier is 16.3870641
Reason being there is 16.3870641 CC"s in 1 CID

Intake BackPressure Canister for Continuous Flow:
2ea.: 1/8" npt King nipples
9-1/2 " of 3/16" gas line
5-3/16" of 1" schedule 40 PVC pipe glued, capped (both ends)! one end tapped for 1/8" king nipple (another for Manifold)

69.71cc theorium and solution
TUBING : 3/16"=.1875"
.7854 X .1875 X .1875 x 9.5"(1/2"=.5") = 0.262311328125 CID = 4.298512548141 CC"s
Engine Displacement of Mine is 69.71CC - 4.29851254814cc (9.5" of 3/16" Tubing Displacement) =
/side note 66.0802038 Left for (Cylinder/Booster can) Displacement/
Plus the Booster can being 1"x 5.1875" (5-3/16") = 4.0742625 = 66.7652007477 CC's
There it is the Print out for you build a PVC Intake Backpressure/Booster/Normalizing Canister
Make sure to either mount it vertically or Clean it out now and then.
I was gonna say that you guys were ignoring the volume of the tube that goes to your bottle but post 175 stated the volume so someone is considering it. If you think it doesnt matter then picture using a 20 ft section of tube and say the same.
I tried to pretty up the link and couldnt figure out the url part on this vbulletin. Odd that a 700 cc machine accepts wht looks like a 10cc boost bottle. Maybe because its a 2 banger or because it has reeds that it needs less. I have this bottle on my snowmachine so I have been aware of their use on 2 strokes for a while but never heard of a 4 stroke using one.
Also another poster pointed out the calculations for 2strokes should be the volume above the intake port and not the entire stroke. I wonder which calculation you should use for boost bottles.
I installed a 80cc kit from Powerking. I am interested in trying a boost bottle.
I am led to believe that the 80cc is really a 69.6cc or so. I need size to order correct boost bottle. Thanks.
DO a Google search of "two stroke Boost bottles" and read the reports on there success or failure, before you purchase one. Look at the factory bottles and use the rules that must be adhered to for any success. Good luck. Have fun, Dave
PS: I would use the space for a drink bottle at least you could have a drink.
I got a boost bottle and nitrous kit for my bike and I was not happy about the outcome at all. I'm not saying it doesn't work, I'm just stating my experience with it. After having to painstakingly drill my intake manifold for the nozzle and hooking it all up I started my bike and to no surprise it idled higher. I knew this would happen but after messing with the idle and trying to tune my air/fuel screw it just wouldn't stay running. It made my motor have massive vibrations and the nitrous did not help in any way. The crew and Dimension Edge now has this kit and is figuring out ways to make it work for me. Something about the tube lengths and stuff.... I was just so mad about it that I didn't care anymore. I'm positive there's a way to get it to work, I'm just not smart enough to figure it out. HAHA
