    Default How to increase Mehran Performance On CNG

    AOA,

    I have mehran 2007. When I put the AC on, it reduces the performance remarkably and AC is also not so good.
    Please give me some suggestions to increase the performance of AC as well as engine. I have some list of upgrades, that could be considered for the solution.

    1.ngk ix plugs BKR5EIX-11...
    2.10.2mm plug wires
    3.simota intake....
    4.oil breather......

    will these help in increasing the engine performance while AC is on?
    any suggestions about to improve the AC performance.
    Waiting for positive response.

    Meray bhai!

    Nani jaan kay pechay koon prrain hain... 800cc CNG car hai aur uper sey AC.

    I really dont think that you should spend that much on Mehran. Treat it as a city car, it is very good little thing.

    Hi Dear, I have Mehran VX-CNG 2007 and installed DENSO AC from Authosised dealer. I dont think performance or pick can improve. I also used Mehran 1994 on AC and CNG, and faced same problem in it. You have to go for 1000 cc for better pick. Guys plz advise. thanks

    @ mazhar nazeer and masif33
    my bro has a mehran also for travelling in the city (karachi) crowded places etc, he had the same problem, but when i advised him to do the followings that problem rectified.
    if ur ac perfromance is not good, chk the gas level first, make sure u r using 134A gas and not the 12number gas so refil / charge ur gas frm a reputable place.
    if still your perfrmance is not good chk the dryer as well as the coil VALVE too. if the valve is weak then you will loose 50 percent of chilling !
    if u have some ample amount to spend on , change to sanden 505 or compatible compressor (but of sanden) not denso.
    put relays on AC condensor fan as well as on blower too., chk your cut out settings whn u r switching on the a/c is ur car cut out and generator working n charging the battery properly or the volts are dropping ?
    hope this will work

    @nadeem
    What about the engine performance, whether the AC load will decrease after that?

    @Nadeem:
    I m concerned about the usage of aftermarket performance add-ons as follows:
    1.ngk ix plugs BKR5EIX-11...
    2.10.2mm plug wires
    3.simota intake....
    4.oil breather......
    What r prices on them? if possible post pics? r these good for a CNG Mehran?
    MAX sports guy said SIMOTA cannot be installed to CNG Mehran. Another parts shop guy said they will make slight alteration and adjust above carbeurator for CNG Mehran.
    Is it possible, please show if u have pics?

    About AC performance, i have an aftermarket SANDEN genuine installed to my Mehran 2007. It has been 10 months since install and its running perfect, still cooling very good.
    You have to perform some routine maintenance to let it work better. like, air blow ur AC grill, pressure water AC grill, get AC serviced at least 1ce annualy, check battery water in routine and fill up whenever necessary, park at shaded areas, get tints on glasses or get netted shades for windows.
