aa...'m the same guy...after that posts was away with academics...so back again now...
sorry guys again for the sms language...wont happen again!!

NOS safe test 1

hai guys 'm doing ma final year mech-automobile engineering in trivandrum
'm not an expert in things 'm saying ..just with limited knowledge and stufs i learned...

2 days ago i tried by injecting oxygen from a cylinder to the air filter box of rtr180 ( without removing filter)..

as i increased the flow using regulator from 0 to higher the rev started increasing from ideal state to 5000+ rpm ..then started decreasing...i stopped o2 supply then....that was day 1 .... ... i think the decrease is due to lean mixture....

next will try between filter and carb. with throttle adjustment..

about that o2 supply....its used for medical purpose and welding ...u will get ur cylinder filled from any refilling station...where there is hospital they need o2 ...so there will always be o2 station nearby... rigt!!

for filing that mr. butler bottle well not many dealers will agree. ..check pressure capacity and make contact with them

( note: ... 'm having o2 cylinder , because its needed for ma btech project...so cant push others to buy that. it costs around 6k + regulator price)

hmn....E...C...U !!

i think there is no roll of it in here....

see...lean mixture happens when more air is passed ...it happens when u put free flow filter in r15...if u try to introduce free flow of o2 into r15....and ride....take an insurance before riding ....bike will be history...insurance is for you!!

no much of a flow is there ma friend!!
(guys.....fell free to criticize even if you are not sure...who knows??.... u may point out new ideas accidently, believe me..)

this is very much like supercharging.............!!

You will have to adjust the carb in the rtr for the extra oxygen in the mixture..
That will increase da fuel supply so mixture shouldnt be lean..
But by doing this your fuel mixture will be rich at other times when you are not using your cylinder.
Good luck with your project.

Hey man! I think o2 would be something too much to try with our smaller capacity bikes.. With more combustion.. the engine also would revv higher..

What i was trying a few days ago with my yamaha is, making a turbo like stuff.. i fitted a small CPU fan in a circular box with filter element passing the air in.. and that was connected to the carb.. Generally.. our engines suck air.. my idea was to inject air.. adjust the mixture ratio and see the difference.. but sadly.. my yamaha doesn't have a battery currently.. so trying to get it on.. actually no place left to fit any.. so working on it.. u can try that to if you have all the resourses available.. by the time i get my battery working to test it..

Ha ha ha..R15 won't get killed so easily.....It is only when the Air Fuel mix is at ideal 14.7:1 that maximum heat is produced in a ICE...Adding more oxy will definitely increase combustion chamber temperature to a certain extent only, since you need adequate fuel droplets also to burn.It is the increase in the volume of exploding gas oxy mix which will blow the gaskets,seals and make a Banana of the connecting rod.....One other incident to happen will be pre-ignition..since Oxy also ignites with spark,and early intake will lead to dieseling...(Hope this throws more spanners in to the gears..).....

i have allready tried that one in my rtr 180 that was my "ALTERNATE TO K&N FILTER" fitted a small smsps fan at the air filter inlet with a switch near handle......it worked like supercharging...there was small noticeable increase in performance ..everythg costed less than 50 rs ..but the thing was rotating at same speed when idiling, acceleration, high speed...idiling became lean...i tried to put up a circuit to increase speed of fan with engine speed...mean time got another idea, so went into that

well i think, its not that difficult o blow up an engine...if u introduce 100% o2 at the idiling time ..then also u can blow up the engine. .....if anybody got doubt pass o2 to a burning match stick , it will become a flamethrower for a sec...wihtin a short span of time all the combustibles will ignite at once, that's the blowoff point..

so i think its always safe if we increase the o2 ratio from 21% of air to 50-60% !! rgt guys? lets find out!!

@ metal manic

heres some pics for u!!

alternate for k&n

hope this will help u for ur mods!!

Did you remove the air filter ? because the little compression of air you get with the SMPS fan will get damped by the filter element...try without the filter..I think the bike will have some improvement at lower rpms

there is no gain without pain (risk).....

generally the power boost for engines are used at high rev, and high speed, to reach that extra 20-30 kmph speed beyond ordinary top speed.

another simple fanda is
Additional O2 fastens the combustion, but doesn't give additional power.
rich fuel with extra O2 can delivery additional power.

there are dozens of experiments done around the world like this , Google you idea and see the results, before you take any venture.

It will surely increase the power output at the cost of engine life due to the flow of dirty air. Another idea could be that the fan should be fitted after the air filter & not before it.

Yes , but the SMPS fan is a whimpy one and cannot provide sufficient pressure for any noticeable improvement..which is why I had suggested without filter to KNOW the difference...otherwise I am against even any cotton free flow filter.Paper filters are air filters of choice for engine longevity.

guys.. i dont know how easy or difficult this will be, but i had an idea.. not any different. just maybe a little simpler and easier to test while actually riding on the road.. what i thought was, if someone here has the resources and can get a hold of some pressurized aerosol cans compressed with O2, then that can be connected via a thin pipe which goes into the air intake box beneath the seat.. a small hole can be drilled in the air filter box easily (have done it on mine) and the pipe fitted into it.. then while riding, the aerosol can button can be pressed to see how much actual difference the pure oxygen makes..

one more thing it discovered is that the opening of the air intake box, that is beneath the seat, is not big enough for the air to be sucked in freely. so what i did was, drill lots of 3 to 4 mm holes on the side of the box before the filter.. so that dirty air doesnt get sucked in.. i drilled atleast 70 to 80 holes at a distance of half a cm each. after that, i started the engine, and put my hand near the holes, just close enough but not covering them.. and as soon as i revved the bike even a little, i noticed that inspite of the stock air intake passage open, a lot of air was getting sucked in from these holes too.. i could instantly feel a slight difference in the responsiveness of the engine.. i wont claim i got some major performance boosts out of this, but i definitely noticed that the engine had to struggle less from lower rpms.. i could ride at lower speeds than before on the 5th gear on my 2003 pulsar.. moreover, although i did feel a little difference throughout the rpms, i couldnt measure it as my speedo's dead. but the tachos working. so i saw that earlier my bike used to struggle to climb rpm's after about 7000 rpm. but now it easily climbed upto 8000 rpm..
