Forget TURBO in today's scene, here. First, bring liquid cooling to higher capacity bikes (150+) and then talk about fitting a turbo. A bike engine should be capable of handling that & plonking a turbo on a single cylinder 150cc, well, sure a MIRACLE.

I dont know about turbo feasibility on the bikes .. but we guys tried out sumthing called naturally aspirated engine used by the famous ferraris .... well actually not at that level but we tried it on our P-220Fi and the results we got were amazing .....
What we did was get 2 cones and attach 2 tubes to them and put them where the air supply of the engine goes ... so now instead of the engine to suck up the air and do some work we provide the engine with air as the bike moves .. and it is pressurised too ... it leads in better combustion and more mileage since the bike is an Fi .... I would uplaod the pics of our setup shortly ...a s soon as we put it up again (removed it for some reasons not technical)....
The results we got were amazing ... our bikes pick up and response to gear changes was so much better and we also got all the data checked at service center and also at our engine lab in institute ... the results were all very positive and they suggest that we can go on with our experiment as a proper setup.
I could give u details in case neone wants to try it out (it will hardly cost arnd 50rs to set it up)....
The only drawback of the setup is that ur topspeed reduces coz in Fi the fuel supply is constant so now at high speed the airi is too much and fuel less..... so for that we are making a electric controlled switch ... What it will do is ... at arnd 85-90kmph it will shut off one of the air supplies and only one tube will be open ... this way the air will be not in tooo much pressure and the results will hopefully be gud ... We are working on making it ....

Sadly i dont hv the pics of our setup but I will definitely put them up as soon as we hv it on again ... it was one of the experiments we did on our bike and the Fi bikes owners can surely try it out .. its cheap and gives excellent responses....

Seems Intresting. Please post pictures and tell me how to do it?

Did you put one end of wire into the exhaust gases coming from the silencer and other to the air filter box?? What is a cone??

Great experiment lavs...
But the main thing is that turbo is not meant for 100cc,150cc or 200cc bikes basically Turbo was made for Diesel engine for Mountain climbing.Main thing is that were we can find such small turbo to fit on a small engine,the bike which comes with 1000cc engine can find a turbo for its displacement.If we put bigger turbo the bike will suffer from turbo lag means no power in initial pickup and it will make engine hot and after sometimes engine will be ruin...

ur experiment is nice. It's basically a ram air induction and works only when u r on move.This can be seen in old as well as new american muscle cars. It's them who made this popular.

BTW should u guys really need a turbo on a small single cylinder engine? for more power u can force induce the engine at a lower cost and effort if u r willing to use a super-charger. The SC works without hesitation even on small engines unlike turbo. Also it is not as complicated as turbo.And theoretically there will be no lag with a super-charger, providing a boost right from the start through out the rev range.It can work fine with carb, but u may need to upgrade to bigger carb since the stock ones won't be able to handle the increased air flow. Also i should say since it's driven frm engine some power is consumed by SC. But still ,considering the pwr boost it can provide, the favour will be for SC.

guys wont the usage of a free flow exhaust in combination with a K & N be a better, simpler & cheaper idea for a good power boost. We are just talking on a topic which is virtually impossible.

NOT BEEN THERE NOT DONE THAT

Nithin.J

The mods u said are basic which will increase ur pwr by a max of 5-7% on well tuned set up equatin to some 1bhp on our indian bikes. which is very marginal. And adding a SC is not impossible u need some patience and necessary contacts. This mod can give u power boost >50% flat. That's Like getting some 26bhp+ on a ZMA. tuning for higher press boost obtain some crazy figures, along with sometimes a blown engine. But a 50-70% boost can be achieved safely.
Hope now u got the difference

Dude.. who said its not possible?? It is very much possible if you know someone who knows the art.. And ur K & N is no good.. its such a waste of money..

Dude i meant two stage turbo charger, not stage two turbocharger. Two stage turbocharger means a smaller turbine running on the exhaust gases which drives a larger turbine.And yes those cars do sport turbos on them .But they were built strong enough to handle the massive pressure due to the turbocharging of the engine. I suggested titanium valve kits to strengthen our little engines which were not designed originally to handle so much pressure. You can also use normal valves. but the chances of their failure is high.
@Nithin.j: Search TeamBHP for Venugopalan's supercharged fiero.

^^ either ways, even if you use a smaller turbo to drive a bigger one, the lag will still be there dude.
