I don't think a Turbo can bump up the bhp of a bike, & that too double it, is highly doubtful. I was on the verge of getting my Comet Turbo'ed, but I sold the bike before temptation got the better of me.

CHEERS,

Obviously it cant double it.. But Ninja 250R is 33ps.. and the results were shown by a guy who did a dyno test from US.

Not necessarily. Indian car engines that have turbos ( like scorpio, safari, linea etc ) dont run titanium valves etc. There is a certain amount of boost that a stock engine can also take. But you need a solution to the heat generated by the excess fuel burning. ( same for 2 wheeler engines ).

A 2-stage turbo will be too laggy to say the least, and will have power only during cruising.


Here is some info on how turbo works to clear your doubts - Turbocharger - Wikipedia, the free encyclopedia

First problem is to get a small turbo.Only IHI makes one AFAIK which is small enough to be used on small engines, but its difficult to get it and parts for turbo are not easily available.Then even if you can make piping for the intake and exhaust lubrication will be a problem for which you will need to make another tank(oil).After that you will need waste gate and blow off valve.If you succed to do this much the engine will be able to take no more than 6-7 psi of pressure.Then comes problem of fueling.Its next to impossible to tune the carb for turbo engines.It wont work properly and fry your engine.So u need to fuel injection.So the amount of time and efforts wont yield the expected results.So better option is to go for bigger engine and then for turbo.

^^ the issue of tuning can be solved by installing the turbo between the carb and the intake manifold.

here's a video of hayabusa with turbo the best hayabusa ever...

With turbos there's one big issue and that's getting it to spin up properly. WIth a single cylinder (like most indian bikes) you have only one exhaust pulse followed by a long dead period. So the turbo will never really spool up to the speed needed to build boost. Only once you have three or four cylinders will the turbo get enough continuous exhaust pressure to spool up properly. (Not saying it's not possible on a twin cylinder engine, but the challenge will be much greater.)

On top of that you need a fair amount of plumbing to route the exhaust and intake to the turbo, oil lines would also be needed. Let's just say the gain compared the expense would be less than stellar.

Oh, and fitting a turbo on a bike is a great way to turn yourself into a fine paste sticking to a tree or the back of a truck. Boosting the power of any vehicle without also upgrading the brakes is suicide. With great power should come great brakes.

Have a look at this.

^^ Neat, however that's a supercharger he's running. That's a different beast, since it runs from the crankshaft instead of exhaust pressure.

JD sir can please tell me how can we place the turbo after the carb.I didnt get what you said.Can you please explain more.
