So exploring things for my next custom performance engine and came across this. Its a intake reservoir that takes advantage of the intake ports inertia and "boosts" the intake...

online forum users are reporting that they are seeing an additional 2mph top speed on goped scooters... the same reports of higher RPMs and power on smaller sub 30cc engines... now this does not sound like much of a gain until you do the math and realise how much more power you need to get from an engine like 40cc to push the load (rider aprox 170 lbs) from a top speed of 25mph to 27mph...

I wonder if something like this can be redesigned for use on an engine that is not always upright... it does make the carb stick way way out there though.

would't it be much easier and cheaper to just buy a gallon of 30% (less oil) and mix 12oz of 30% to 116oz of gas to make 1 gallon, add your oil and fly,, you would get a good kick in power, and with this mix 1 gallon of 30% would mix with 10 gallons of gas

easier... not sure, but not cheaper over the course of a few gallons... this item sells for $47... it does not get any cheaper or easier than that to add aprox 20% (maybe less i dunno) more power... bad thing is that its designed to operate in the upright position only due to fuel puddling in the box if used upside down.

you might talk with TRM, he has fooled with this setup before.

I have seen the Boost Bottle for a gasser here::::
The manifold is much thinner but I guess the same principal I don't know.

I would be skeptical. I remember about 5+ years ago, they cam out with this thing for trucks, i think they were called hurricanes. The went between the throttle body and intake i belive. They had fins inside that claim to have put a spiral on the air saving MPG. Then there was some magnet thing to save MPG. I think these are the same, money making gimics.

but if it doesn't work , will you be the first to try LOL
but not cheaper over the course of a few gallons
if you pay $30 a gallon for 30% with no oil in it, and mix 12oz with every 116oz of gas, that will raise the price of gas pre Gallon by $2.50

I don't find that a lot $$$ if a guy flies 10 gallons a year or less, even at 20 gallons a year what is $60 more a year in this hobby..

don't forget to open the Jets a bit for that first flight

Both of these things have been around for awhile and if they really did anything I think we would have heard about it by now.

I think an actual bench test is needed to determine whats actually happening... I agree, if it were really that good we would hear more about them... but the go ped guys are the ones talking about them, some claim more top end power etc, but the one on the e-bay heli would not work... the long hose would cause issues with resonance... as with all intake runners, the shorter they are the more they favor high rpms.

reah I remember the "hurricane" and vortex items for cars... they worked by fooling the MAF sensor, so they didnt do anything. these "boxes" on the other hand effect the intake volume without changing its length...

might pick one up to see what the deal is, its not much anyway and an easy bolt on.

Maybe they do work for the go ped guys but at what rpms is this thing tuned for if it works? Maybe way out of our helicopters workable rpm band. I wouldn't think it would be tunable for different rpm. If that tube thing I posted ,,the bong or whatever it's called worked at all I would think it could be tuned by the length of the tube leading to the manifold.

according to what I can find pretty much WOT on the go-peds... these guys are running all sorts of mods... big bores, top of the line tuned pipes, etc, and are pushing these engines into the 10k to 13k rpm range to get full use of the HP.

been reading up alot on these intake reservoirs and they are not for engines that operate over a wide RPM range... seems they work just like a tuned exhaust pipe but on the intake side... so right there that tells me that to be effective it probably has to be tuned and that there is a PITA.

yes, but you really should know more about what you are doing, when using Nitro you can not have to much Compression or your engine will over heat or make it very hard to tune.

I have a Super Tartan Twin 44cc and a Super Tartan 22cc Plane engines, they run on Straight Methanol, no Nitro, these engines have a 11:1 Compression Ratio, and 11:1 Compression is too too high for any amount of Nitro,,,,, these same Tartan engines with 11:1 Compression were also manufactured with Ignitions to run on Gas/Oil,

in my Link) I know people do mix 1/3rd 10% Glow Fuel to 2/3rds Gas and run a Glow Plug with no Batteries/no Ignition in Large Scale Plane engines from 22cc up to 40cc and even in twins,, see my link for this Gas Glow Mix Info,,,, just know that Heli engines run Hotter than Plane Engines.

http://www.rcuniverse.com/forum/eng...o-ignition.html

a good place to start if you want to try adding Glow Fuel to your Heli's Gas is adding 5oz of 10%,,, please know and understand that NOT all Oils that are used in Glow Fuel will mix with gas, some will mix some wont !!!!

my 44cc Twin,

my22cc,

The problem is just like tuned pipe exhausts I would think,,,they will hold like stink in their rpm band and when you exit this area they are SLOW to return unlike a regular exhaust.

I assume gearedheads posted that. That maybe true but do you want to risk your stock or modified motor to this kind of experiment?
At least I would go to Hanson or Toxic and ask. Who knows what oil they use in the nitro fuel? It may NOT mix with gas. I would say either you fly gas or nitro ,,not both unless you have expendable engines to figure it out. Want more power?? Fly nitro and pay the price. This I feel is not good advice to attempt in my opinion.
Also why would you want more alcohol in your gas than there already is? I have read the gas engines {Zenoah] can work up to 10% alcohol,,you would then be increasing it to add abit of nitro to make it work even harder. What is the effect of higher alcohol content and nitro do to the diaframs of the Walbro carb?
My 26cc Hanson is going on close to 10 years now without a problem.

They do work, but mostly when a fast change in RPM is needed, like changing gears, it gives a little extra pop, just a little, as far as tuning goes the reservoir has to be close to the engines size, so a 26cc engines should have a 26cc reservoir and they work better with a reed valve engine.

P.S. sorry for the spelling or the grammar I am dyslexic!
