    My reccomendation is not to rely on the "expert advice" of the road side shop mechanics. They are not "trained engineers"

    IN Pakistan, your best bet is to go to the best possible shop where the shop can actually be held responsible for the work they perform and where the technicians are atleast somewhat better trained than what is available on the street.
    It is not good or proper (ethical) for me to reccomend shops but in Islamabad, there are several proper shops in I9-i10 area. As I always reccoemend , u can never go wrong with the dealer. They are rip offs but atleast their workers are properly trained

    when u will block the air intake,
    u will reduce the gas(from the 17# nut for adjustment) as well to make the air/gas mixture perfect

    if u will keep the gas a bit more open, acceleration would be good.cut it down a bit, pick will be reduced but oonsumption would be better

    if i dont block my hondas car intake, it does not iddle with AC switched on majboori hai
    Life is short and very unpredictable just like a Quarter mile .....

    Explain me / correct me if im wrong
    i guess
    50% Methane (CNG) + 50% Air=100% power
    Suppose mehran`s engine is generating 35bhp on this above condition

    Methane 50% + less air 30% =80% power ,therefore engine will eat try to gain power by taking cng a lot
    there for for 100% power=70%cng+ 30% air=100% power

    Methane 50% + air intake 70 %=120% power
    there for engine will take less CNG to have 100% power
    30% cng + 70% air=100% power there for
    low consumption of cng
    correct me plz
    Trying to be real slow turn up the bass real low get the sounds that head low tune the channel of EXO gonna take to the level where speaker streams ,ready to rattle up the box

    as far i know , don`t close air intake ,let air flow to engine freely , if there will be closing of air , then to generate same amount to power , engine will take cng a lot to generate same power

    immidimi
    under same power of engine
    13" greater acceleration / lower top speed
    14" lower acceleration / greater top speed
    IN drivetrain
    acceleration is inversely proportion of top speed
    top speed is inversely proportion of acceleration

    Assalam o Alicom Guyz,

    My Civic and Alto are CNG, in that there's no blocking of Air intake..

    But in my City i-DSI M/T when i got it installed the cng installer didn't blocked the air and said it will choke your car engine.. the pick wasn't good it was worst, I was like I did mistake in buying City i-DSI, afterward from other CNG mechanic he blocked the intake 70% or somewhat like that and adjust the nut for perfect mixture.. beleive me city pick has gone good and so consumption... But I'm still confused if I'm choking my car while my city intake is 70% blocked!

    I have driven mehran on cng and It pick is good I don't think Mehran need air intake blockage!
