Any one converting bike from carburetor to EFI?

[user-xxx]

Excellent work bro a lot of guys are looking for this efi system in past threads. It will be really helpful for them.

[k-four-nine]

lol for what purpose you came here ?

illumination.

OK.I just told what I observed (after PRACTICALLY doing it), opinions might vary from person to person.

I'm not saying you are telling a lie; I simply stated facts and you can look them up if you like.

I think what you experienced is called 'psychological illusion'. An EFI bike can't be noticeably faster than the carbureted one, but your mind told you otherwise when you rode one!

Here's an example of illusion:

In this video people were handed two identical iPhone 5 smartphones but they were told that one is an iPhone 5 while the other one is the latest iPhone SE. And their reactions are absolutely hilarious!

Anyhow, like I said; everyone is entitled to his opinion. And all I'm doing is putting 2 and 2 together so lets not start a debate.

Well done Wajahat Ali thumbs up for your Great work the best ever project i seen in my life

Yeh i know the psychological illusion. In this case, It is like if you have spent more on EFI system vehicle than you will make reason in your mind to justify the extra spending But you have to consider that EFI system adjusts according to air intake and exhaust readings so it just put the precise amount of fuel in the engine to make optimum power. So as a result you get more power output with less quantity of fuel.

With today technology they want to extract maximum amount of power from each drop of fuel so the competing machines used in circuit track racing are given limited quantity of fuel with that they are racing to get the top position so they dont use use simple carburetors in these machines. with technology advancement they used efi than port injectors and so on..

That's harsh! You just broke my little heart by saying so many mean things about me.

But... Do whatever makes you happy.

Free world, eh?!

So as a result you get more power output with less quantity of fuel.

Precisely! And I don't recall saying otherwise. You're absolutely right about most things.

But the thing is Mr. 'Arnold Schwarzenegger' (I can't help myself!); the power output of a naturally aspirated engine heavily relies on the displacement of an engine; which means a 70cc engine can't possible make power output comparable to a 100cc engine (with everything being equal i.e number of cylinders, valves, camshaft, intake and exhaust manifold to name a few.)

In short:
EFI dramatically improves the combustion process and makes it more efficient and reliable, no question about it but... I doubt you'll witness 'significant' power output gain or sharper throttle response with EFI modules as compared to old fashioned carburetors.

It's just...

Physics!

To squeeze more power out of a given displacement; you need forced induction (Turbo or superchargers), not EFI modules!

Hope it clears any confusion!

Au revoir!

Benelli recently launched two bikes in Pakistan ( 150 cc category ).One of them is EFI(Oil cooled with 2 spark plugs),other one is non Efi. Power output of non-EFI is 11hp and EFI version is 14hp (Mileage is also better) according to company officials.Torque figures are also different.Problem is not with Physics but with your understanding.In simple words which you might understand ,Power was always there but EFI just increases engine efficiency to reach that optimum power.You need some detailed research that how EFI,fuel pump and injector atomization works, rest of your viewpoint is fine keeping your image of EFI in mind.Not trying to start a debate but please do some detailed research and not imagine things. This forum was to help someone who needed help about EFI installation on bike, not to clear concepts of EFI.

Bro i am extremely sorry if any of my words disturbed you

I was just joking, if it wasn't obvious already!

Don't worry. I can endure a lot of beating without breaking a sweat and don't mind getting criticized.

Cheers!

Power output of non-EFI is 11hp and EFI version is 14hp (Mileage is also better) according to company officials.

Well, an engine's compression ratio also plays a major role when it comes to power output and two spark-plugs per cylinder dramatically improve combustion efficiency. Lastly;

Horsepower = Torque x RPM ÷ 5252

In my personal humble opinion, power output heavily relies on an engine's state of tune, compression ratio and combustion efficiency (1 vs. 2 spark plugs per cylinder). And EFIs and carburetors do nothing but provide air/fuel mixture to the combustion chamber and you being a physics student; should know better!

I'm just a bloody banker with a degree in Commerce!

Nevertheless; EFIs are indeed efficient and hence they do provide slightly more kick than carbs, you're right about that but... I doubt they can offer upto 30% better power output on their own; as compared to carburetors!

This is just... Wrong, my friend! That's not how internal combustion engines work!

So... Any takers?

Great work. Well done.

[Khurramchauhdary]

Benilli launched only one efi version which is called 150i and not the simple one which is 150 but rest of the word have them both.

[umarkamran2001]

Bro is the system 100% waterproof

[mariah190282]

If any one does that I would really love to take a course from him. I would give him money to him for teaching me this stuff. Efi is so efficient than curb-orator and saves lots of our fuel. Turning curb -orator into something like that would be amazing.

Wajahat Bhai can i have your contact ?
i need to convert a 200cc engnie to efi.
need information about it.

can i get 30mm thotttle body and tps and injector ?

[asjdsm]

where can i get this ? is it available i cars ?

@Xulfiqar bro need your opinion

[margallar]

You are very wrong

There is no comparison between efi and carburetors.

just the timing control achieved by efi gives major gains

[docvr46]

The guy converted a lame ass CD70 carb to an EFI. Thanks for pointing out the facts and being an honest mofo. I'd let him think he got his 40% on power and efficiency, you know, for all the work he's done - unlike some bloody banker.
P.S. Thanks for letting us know you studied English at Hogwarts.

How much HP and mileage difference is between Carb and EFI Mehran !
Does Carb Mehran produce 40hp with 15km/L and EFI 98 hp with 35 km/L ?

[Hassan1991]

Efi mehran does not have 98 hp.
And does not provide 35km/l as well.
Hp is less then cultus G10 efi.

[user-xxx]

Yeh obliviously cultus is 1L and mehran 0.8L
