Boost Bottle for freestyle?

[Big Kahuna]

I learned something a few years ago when I started trying different setups........ Keep It Simple..........

Dont fool with it (unless you just like to tinker), If someone found that they actually worked good, then R&D, Riva, Protec, Novi, Full Spectrum, Blackjack and others would be selling manifolds with the boost bottles on them or Modification Kits for them.

i think it is a case by case situation as to whether there are significant gains from it. a heavier rider such as myself can use it for that bottom end hit off the starting line rider, a lighter rider would not see as much as gain from it because there is less strain placed on the motor because of the decrease in the weight of the rider

I do Love to tinker:smile: Just because no jetski companies manufacture them doesn't mean it is a bad idea, I don't think the 2 stroke motor in a ski is much different than a banshee motor. ATV's are a larger sport than stand-ups, yet still there are only a select few quad related companies that manufacture boost bottles for them (Vito's, Nacs,Graydon,etc.). Why? I think it's because the two stroke is a dying breed. But, for the basic jetskiier It would probably be best to leave it stock, stick to bolt on goodies, or pay an engine builder to get the power out of your motor for you. For those who like to tinker here is an interesting read:http://search.aol.com/aolcom/redir?...dItemPage=1&clickedItemDescription=WebResults

I disagree with your theory Big Kahuna,if everyone thought that way there would be no Lamey cylinders,no aftermarket heads ,no pipes and only single carbs.Just because it hasn't been done yet does not make it a bad idea.It is proven on most other types of two stroke applications and the thing is freestyle is relatively new ,not to long back no one was worried about low end response and acceleration it was about hp and the more the better.I think it would be well worth looking into.To the best of my knowledge their are no drawbacks to this system and there are no moving parts,as far as the keep it simple theory it doesn't get much simpler than that.

but do the costs justify the gains?

 

[WFO Speedracer]

Geez Don how much can a boost bottle and a manifold cost?

 

[xxx2]

Costs for me would be just time (I have a spare 44 manifold and enough scrap aluminum To build any size bottle), But retail for them is usually around 40$

when riva made the boost bottle intake for the 66V application, it retailed for 399.99

I was refering to the atv world. With riva I would imagine it is more supply and demand, cause let's face it if riva is the only one making them for watercraft.....Where else could you get one for your ski?:dunno:

 

[WFO Speedracer]

Yeah I really don't see why this couldn't be a do it yourself project.Its fairly easy to do one up.

I am thinking to get the size of the bottle, If you Know your engine CC's on your twin, divide it in half (my case 650=325cc. Take your tube and weld one end shut. The other end pour 325cc's of water in. cut the tube @ the water line and weld a cap on.It needs to be on top of my F/A to be above the cylinder head but that shouldn't be a problem.

They where used a bunch on snowmobiles too, a more similar application....

Try to tune a Yamaha Phazer, You can't get one to run right with-out one!

 

[ROTATION]

Outlet must be at the lowest point of the tank and must be at a height above the cylinder so that any condesating fuel drains to the manifold.

IMO it would be totally useless in a Superjet. The instant you hit the gas you are over 3,000 RPM, which makes the bottle useless. If it does help your low end like they claim, it'd be a lot more beneficial in an ATV.

I've tried one on a banshee before, I didn't feel a difference.

I agree the moment you hit the throtle the RPM's jump. There is no actual traction like a bike or atv so the rpm jumps up past the bottles range to help.

And about Riva or someone making one. Boost bottles are not new so the idea has been kicked around more than once. I am sure that they have tried it..

 

[WFO Speedracer]

The snowmobiles are turning better than 3000 rpms when they start pulling also,yet they still use boost bottles,hmmmmmmmm I wonder why? Also it is questionable how much actual traction snow offers.

 

[Mile9c1]

Yeah I wouldn't think a sled would need a boost bottle either.

ITo the best of my knowledge their are no drawbacks to this system and there are no moving parts,as far as the keep it simple theory it doesn't get much simpler than that.

Tunning difficulty with various setups. Lack of R & D makes a big diff. Volume of bottle, length of hose, interdiameter of hose, manifold inlet size and placement. There are tons and tons of diffrent combos for anything.
