Perpetual Boost Bottle Debate & Discussion

[racecar001]

does anyone use boost bottles on their scoots? if so are they good or not worth it...everything I read on the net says they help lots on 2stroke..

[XPS1210]

I'd like more info on these as well... I know boost bottles work well on RC cars... kinda the same concept as a scooter motor?!?

King you know anything on these?

[Lennox]

These are comon on race skiis. I never even thought of it for a scoot. Think there enough room?

[XPS1210]

I've never seen them on a bike, where do you get them and how big of one would be needed on a scooter?

It basically has a "stored air" supply right?

[racecar001]

they have them at www.maximum-rpm.com I made one out of 2" pvc and 2 caps..... was on a web site and they said for singel cyl. engines bottle should be same size as the cylinder to 10% larger... ie my bottle is aproxamatly 6in long and is in my under seat compartment...on my bugeye...havent tryed it yet will post when I test... :D

[Davey-boi]

would any of those variators and boost boddles work on vinos from that one site?

[King Vino]

Wow, haven't heard this stopic in a while. Man, I'm banging my head. If someone wants to do a search on the forums on this...

[XPS1210]

now king you know that it's just not fun to look at the old forum wheb we can ask it all over again...

[King Vino]

now king you know that it's just not fun to look at the old forum wheb we can ask it all over again...

Not sure back in those days we'd have four conversations going on at once in any given thread. Hell, we could have had ten posts about boost bottles under a thread about turn signals. May have been in the NOS thread. I'm sure it's an achieved thread from 03 though. I just haven't had the time yet to go back and search.

[XPS1210]

I looked at the boost bottles on the site mentioned above... I really don't see how the cost to benefit is worth messing with this... You need to get a new intake manifold (or mod your stock one) as well as get the boost bottle.

Litterally the boost bottle is supposed to hold extra fuel and it can be drawn out of the boost bottle at WOT by suction from the engine...

Not to sure I need this. Just my pennies again but thats what I think...

[King Vino]

Here's my suggestion. Wait till your tank gets near empty, and either put racing fuel in at 4 bucks a gallon or, buy aviation fuel at 2 bucks a gallon which is the same thing. I use to cheat on my SCCA Stang. While all the chumps were paying for racing fuel, I was using aviation fuel at half the cost and yet it was the same Exxon product, LOL. :p

[XPS1210]

could always dump a bottle of octain booster into the tank... they are supposed to upgrade 4 octain points in a 16 gallon tank... for a 1 gallon tank thats like!!!!


154 Octain.... WOW!

[Lennox]

Race and Av gas are way different!!

How do you think higher octane gas will benefit you???

The only thing it will do for you is run at cooler temps with absolutely no preformance gain!!!! Race gas allows you to run higher compression and other mods saftly. Race gas on its own is a waste!!

[Lennox]

and Octane boosters are the biggest waste of money......and they don't work

Anybody wanna make thier own race fuel???

4 gallons of 92 octane + 1 gallon of Xylene = 5 gallons 103/105 octane.

[King Vino]

Lennox, hat was a joke hence all the " :p "' and LOLs

[XPS1210]

now i got to say it... the higher the octain the higher compression you can safely run...

high octain make there less chance of detonation...thats it... nothing else...


i know it doesn't make it faster or anything... just keeps it from blowing a hole in the top of the piston....

[racecar001]

I regret posting this thank you for your replys but upping the octaine has nothing to do with boost bottles....dont you guys always complain about changing the subject? I just asked a simple question.... :confused:

whats another 50 bucks anyway

[XPS1210]

Who complains about changing the subjects?

Also why get upset... It's good info being passed on... Some more useful than others...

You got info about the boost bottle... And there was additional info about the octain stuff as well...

It's called learning and teaching... Then there's always complaining and fighting... Thats all here too.!

:) :mad: :confused: :eek: all in one thread!

[Lennox]

I am often misunderstood on a computer. And I often misunderstand others. Even with all the smilies. :confused:

If any of you ever talked to me on a phone for example..... then It might all make sense? :)

[XPS1210]

well said...

[racecar001]

got the boost bottle installed its way quicker :D 2"pvc 6-7in long 2 caps and a brass fitting $5 bucks to make very cool worth trying

[Lennox]

Faster acceleration or top speed?

How did you document your improvements? Do you have rpm readings for us? GPS? Any data would be great.

[racecar001]

faster from 1/4 ot wot.. no it doesnt help top end but does give it more mid-range snap....rpm's are about the same just better responce

[King Vino]

Actually, I'm pretty anal about topics staying on subject and do not hesitate to merge, or split threads accordingly, but I did not see this thread getting that far off of topic to justify doing such. The discussion of octane stayed within the bounds of the question posted as an alternative way to accomplish a similar result. :) I held back posting this earlier because I wanted to see how the membership reacted, and I for one am quite pleased.

With that said, how are the boost bottles doing on the scooter.

[XPS1210]

all I have to say on this... There are boost bottles... and that's the best I've heard of on 2-strokes for a "supercharger"...

Now... other than that....

LET's PLAY NICE!

[King Vino]

OLD POST: OK, this is one of those topics that comes and goes around here, eternal like the fuel debate. So here's the deal, a thread to bicker all about it.

First of all, just for the sake of debate everyone seems to have a different idea of what a boost bottle is, what it does, and why it sucks. Now go forth and battle brave warriors.

I want a boost bottle for my Nissan :p

[Ghostrider]

Boost Bottles? I'm figuring it's nitrous?

[SychoSly]

It's not really a supercharger. It is a fan like device that just pushes air only CFM no PSI. So the little fan stays on constantly if you would wire it up to the electrical supply, so it might owrk if you add enough fuel. If you make a switch for it then when the fan goes on/off then you will be either rich/lean.

Hope that makes sense.

[scooterconvert]

For too much air and fuel there's got to be a point where the piston just will not come up anymore because the pressure is too great. However, you would need some serious compressed air to do that so as far as super charging goes, there will come a point where there's a max pressure and you just won't be able to fit more in.

[XPS1210]

No not NOS... It's a boost bottle... it's a bottle that holds fuel and adds the extra fuel at WOT runs...

Not totally sure how they work but they supposedly do... I've never used them...


What your refering is a fan that causes a low PSI in the intake system...

1st... plastic fan pieces... I wouldn't use on a intake...

2nd... if you add a bunch of extra air, you'll run lean... Which will cause the bike to go faster due to over RPMing... as well you run the risk of damaging your cylinder...

This is what a boost bottle looks like... I looked at a handful of google results but they were all for the stand up auto parts store scooters...
I can't remember the link for them someone had on here... might try a search on the forum to see if it will pull up...

[King Vino]

How about hooking both up together a boost and a NOS :)

[Zuma88]

boost bootels look tight, but dont do much unless you have somthing like a 120cc honda elite stroke motor. putting them on 50 and cheaper 70cc cylinders are carbs dont really make a good enuff diffrance in perfromance.


reason to buy one: 1 you got a really nice set up. 2 you want it for its looks.
3. its cheap and some one told you it was nos lol. 4 your cheap and you want it to look like you have NOS. 5 all the above.

reasons not to buy it: 60 bucks with shipping. 2 not a big differance unless running a full MHR or EVO kit. 3 hmmm hmmm uhhhh ok next. 4 its a pain to hook up really easy to screw up and have to a new one. 5 got milk?.
6. i farted and i cant find a places in indiana that sells boost bottels.

[King Vino]

I'm going to buy one and wear it to work on my back, so I can claim to be friends with James Bond.

[hybridrazz]

maybe a boost bottle with some cam2 racing fuel in it lol

[scootinforlife247]

A boost bootle will give NO extra topspeed.
It will give a slightly better acceleration.
And it will give a quicker / better responce to the trottle.

The boost bootle is mounthed on the intake manifold.

For performance is does not matter which boost bootle you choose.
It depends on the space you have to fitt the bootle , and which brand you like :-))

[Lennox]

do you think this boost bottle will give my scooter 3times as much power? :rolleyes:

[hybridrazz]

too much power lol

[isoscelesjones]

Is it possible to have a boost bottle for your boost bottle? Boost bottles chained together like kegs at a bar....

[Lennox]

haha, now, thats good humor! :D

[hybridrazz]

boost bottles are also called power box's for some reason, id call it a boost bottle since its a bottle lol.

[SychoSly]

I have been looking into the boost bottles and it is hard to find any real answers.

A few people that have actually used them said they had better throttle response and low to mid-range power.

I figured I will get one. Anyone know of any other place that sells them besides max rpm?

When I google I only seem to find ones for ATVs or Snowmobiles.

Thanks for the help.

[King Vino]

Boost bottles are da bomb :p

[shayandaman]

I was looking at some manifolds with nipples on them to attatch boost bottles and i saw that some of them have 2. I was wondering if instead of just attatching just 1 boost bottle, i could attatch 2. Anyone know if this will be better than just 1?

[lilsilva99]

could i get the site or sites youve looked at them on??

[shayandaman]

sry, I cant do that, its against the TOS because it also sells other parts that are on provoscooter.com and im not trying to take away buisness from that. Anyhow, whatever you need, erich can probaly get, just send him an E-mail or just go to google.com and search. I usually find what i am looking for there. :nerd:

You are mistaking You have to know what the boost bottel is made for ususally they are made for small motors!!!if you have to get one that matches your displacement. good luck finding one..it doesnt even do that much anyway it only gives you allitle bit better throttel response i have one... o_o

[florida derbi rocket]

I don't know much about Boost Bottles...But I DO follow a lot of EURO scooter trends..Boost bottles are not that popular...If they were the Real fix...I would see much more about them...I agree with Wideopen..If your Larger carb is Jetted Corectly...I would think you would have your Joy at WOT..Remember folks...There are more Jets than just the main one..I think Jered or Lennox covered this..The 3 Jets Cover 3 or 4 Throttle ranges..(Look in the Archives).......................................Jo hn From Jacksonville.....(Damn..I got a night off...I'm gonna get Kim..and watch the superbowl Fireworks..) --o

[Aviatrixie]

Boost bottles always seemed kind of silly to me. How much Nitrous can you pack into a bottle?

John... we did the fireworks at Riverwalk on the 99/00 new years eve... amazing show!

no nitrous!? It simply holds a small charge or atomized fuel from the carb.... Gives an extra little burst of fuel when needed.... it would be the electronics version of a capacitor..

depends on the nitrouse bottle....for example 1 gallon tank will hold 1 gallon of nitrouse no more but you can get less.oooo your talking about the boost bottle yea they dont hold nos thanks for quoting lenix i didnt quite understand the question

[florida derbi rocket]

Lennox..how can I put this..Is the Boost bottle something to use..cant this performance be found elsewere? ...I,m thinking a Lot of our forum isnt jetted to the Tweak max..( A Lotta Big Thirsty carbs out there..) :spiny: .. John

[King Vino]

I'm going to put a boost bottle on the cat and she if she can run any faster :p

[florida derbi rocket]

Damn King!! We told You to re-Jet that Cat!!

[King Vino]

Meow! :neko:

[RC51 Daytona]

Boost bottles were first used on 1981 yamaha IT 175's I believe. The theory is: During the two stroke phase of an running engine, the piston actually bounces some of the charge back out thru the carb. If you run a boost bottle, two absolute rules must be obeyed: The bottle must be above your cylinder, 2) the cc's of the boost bottle, including the area of the line going to the boost bottle, must be calculated. The size makes all the different in the world and a finely tuned bottle will help your low end. Jolly moto in Holland, sells two different kinds for the 50cc motor. You could probably make one out of pvc, but it must have a free flow for the gas and vapor to flow back into the intake manifold , where most of them are plugged in.. My 1984 Yamaha RZ350 two stroke , had one , and they do work if properly tuned. So many elites have different big bore cylinders, you would be better off making one yourself... ;)) A lot of guys in the islands , put the bottle up behind the seat, under the fairing.

[florida derbi rocket]

C'mon RYDAH .. Represent our 50th state!!..(is that correct?) Tell us how the Island boys use the Bottle.......John :race: Thanks daytona ..its nice getting Real info..

[lilsilva99]

Ive seen a system where you have little bottles like Co2 botles full of "nitrous" or something...But it was an in jected boost bottle....How come I never hear bout these, and do they work have any one seen them? and are they safe for scooters?

[RC51 Daytona]

I saw a picture of a drag scooter in Hawaii with a nitrous bottle under where the seat should have been. The scooter was stretched and made simple for drag racing. I think it held some speed records, but I am not sure.

I always think of ways to increase the speed of these two stroke motors. I just had to rule out Nitrous. For a number of reasons. First , the only place to put the bottle is under the seat and then you have to turn the bottle on , before firing. Then you have to ignite the solenoids and arm the extra electric fuel pump. Then you rev the engine, Bang on the nitrous injector, HOLD on for dear life , and Pray To Hell SOMETHING big does not get in you line of trajectory. Turbo is out of the question because it needs a constant oil supply for its full floating bearings, Which leads us to belt driven supercharging. I actually saw picture of a guy who had a little six inch long, roots type blower on his scooter. Where he got it , I dont know. I would love to check that out. :)

If you can get some info on that supercharger i would love to know me aqnd a friend have thought about how to make one for quite some time but could never figure out all the little things how to get the parts and how to keep boost perfect and how to make perfect seals.any info about it would be appreciated. :spiny:

[RC51 Daytona]

I will try and find it. The bike looks like a ruckus but made in europe. I would not have believed it , unless I saw it with my own two eyes. I heard it might be a air conditioning air pump off a mercedes, adapted to the bike , with fan belt running off the rear pulley. Believe me, I want one just to experiment with. :)

[shayandaman]

yea, i would also like to see some more info on that supercharger.......

[shayandaman]

Does anyone know where to get a nitrous kit for a 2-stroke scooter?? i am trying to buy one but i cant find someone that sells the kits(N20 bottle, hoses, gauges, buttons valves, etc) send a PM if anyone knows.........

[smokin]

ya I do but it's gonna burn a hole in your pocket... o-- 215 for a dry kit 650 for a wet.

[King Vino]

I think my old boss, Matt up the YMC dealer started to sell them for his Kymcos, cause peeps want them, but he refuses to install them. The man hates scooters like I hate emission inspections.

[smokin]

If I had the bread to back it up I would throw down the 650 or so dollars and get that wet system but I can't because my motor parts alone are burning a hole in my pocket but there will be no need for nitrous i will be going plenty fast enough after what i've seen and arisal do I am expecting super big speeds but it would be cool to have it especially to see the look on peoples faces when you have a four foot blue purge coming out of the slits on the front of your body at a stop light race and then see the look on their face when your front wheel is way up in the air!!!!

[King Vino]

Ah, bullocks, it's only money!

[smokin]

Ah, bullocks, it's only money!

ya but i don't even have my motor together yet. maybe after???maybe smokins how to's ?!?!? :D

[King Vino]

meh excuses, excuses :naught:

[RC51 Daytona]

I went too a site that turbos bikes and they had a side bar on supercharging bikes on the cheap. What I refered to earlier, was a smog pump, or an air injection pump. they were mandated on cars in the early 70's, they are made of aluminum, centrifical in design and they have a pully to run them. I hear you can pick them up for as little as five dollars at your local junkyard.. How and Where to put them on a scoot is the problem.. So people, SUPERCHARGE THOSE MOPEDS!!!! :)

[marylandmark]

Info I found on what a boost bottle is in case others didn't really understand:

SUPER INTAKE BOOST BOTTLE
Anodized blue boost bottle is designed for better throttle response and faster acceleration. Attach the hose to the intake. When the engine is running the boost bottle will fill up with atomized fuel. When the throttle is quickly cracked open from a closed position the intake will suck pre-atomized fuel from the bottle providing the engine with an added burst of fuel off the bottom when it is needed without changing jetting which could cause it too run rich (too much fuel).
Good for getting the holeshot when also adding other hi-performance parts.

[911elite]

well i have one and it dose help with acceleration, its easy to install as long as your ok with drilling your intake. The part about atomized fuel is a bunch of BC it dose on the other had improve your acceleration and mpg it picks up the fuel your motor wiaste and sends it back in during take off. I would recommend getting one for 3 reason's 1. Looks good. 2. improves acceleration and mpg. 3 with a big carb it helps out the take off alot.

[monzav8]

Im curious, how long is the tube that connects from the bottle to the intake, and about what diameter is it?

[bmt49]

Two strokes do not have valves like a 4-stroke does and many if not most 2 strokes operate on 'pulse power'. Meaning the air/fuel mixture is constantly pulsing through the intake tract, cylinder and exhaust port hundreds of times a second, thousands of times a minute, back and forth back and forth as
the piston goes up and down. Except for right before and after the spark plug ingites the compressed gas the cylinder is virtually always 'open' due to the open ports. As the piston moves down it creates suction which 'pulls' the air/fuel mixture through the intake tract and ports. When the piston reaches BDC (bottom dead center) it starts back up compressing some of the air/fuel mixture and 'pushing' some of it back out through the ports and
intake as well as out the exhaust port. When the piston reaches TDC (top dead center) the spark plug ignites...KABOOM...and starts the whole 'cycle' again.

As I understand it, although the boost bottle dosen't really 'hold' anything, theoretically one can smoothe out these 'pulses' and aid the mid range and acceleration by adding volume to the intake tract...without adding length.
I think of it like this: water flows into a small lake from one end through a swift stream, then eventually flows out the other end in another swift stream. But while in the lake, because of it's volume, the water is relitivly.....calm.
