Hi,

i have been doing this research for long on how to compensate the power loss caused by CNG which is a dry fuel in nature. as of now i havnt find any support in that.. but couple of thing that comes to mind are, will adding :-

1) K&N air filter
2) Free FLow exaust
3) single turbo charger
4) high performance spark plug

can compensate the power loss or will they harm the engine for CNG being the Dry Gas ?

any inputs will help

@ Fl|rty
High performance spark plugs will help but will not fulfil your requirement. Instead go for tuning of your CNG kit. If it is properly tuned such as air/gas mixture is set properly, power loss is reduced to minimal. If you could kindly tell me your car type such as EFI etc, I may be able to elaborate further.

Keep one thing in mind though, at best 5-10% power loss is always there for CNG.

thanks for the info Bkahive..

i have '05 baleno done 7000 KM.. though as of now i havt retrofied it with CNG. but will be doing so very soon after getting its 3rd service done this sat.

i think adding the air filter and comple air intake and exaust makeover can fill the gap between CNG and petrol though i am not looking for a peak performance or very high performance but i guess if i can get around 15-20 More HP then that can compensate the power loss.

on older car there is extra loss of power cause of old spark plug, old clutch plates etc.. apart from burning CNG..

for air mixture i have K&N stock air filter..

wats you call on this ??

Honestly....for the amount you will be spending on a Turbo set up....

fill your car up with some decent petrol...and enjoy it!!!!

Instead of Turbo C, Get a Free Flow system done from Auto Mech would cost around 12- 15,000 considering thats what manveet paid for his OHC.

Basic improvements can be made by By getting nice cool air into the throttle, Suggest you go for side vents or bonnet vents to enhance cool air intake and also cool the engine..!+ Free Flow would be a better combo..!

I think Mico Bosch had launched the CNG 4 Node Spark plugs, You may want to search for them...Even Iridium or NGK have special CNG plugs..but they are expensive though.

Advanced Timer or Lamda ECU system for the CNG Kit, To enhance Pickup and FE.

So In all if you get all of these done, It might cost around 25 K or Less.

Also you could look into Alloy wheels to reduce overall weight...! Unless your Baleno has them.

yep.. infact i did some research on them.. but wasnt able to find any special CNG plugs.. all i got was NGK...

i have given my car for the CNG conversion.. no one was willing to convert my car into CNG as my car is a EURO III and no one is athorised to fit the KIT.. but then i heard abt nugas and they were willing to fill the kit without voiding the gurantee of my car.. will be piking up the delivry of my car today..

then will be going directly for NGK plugs.... i have exausted all the money so probably will be going for cool airintake next month once i get my salary.. this Kit costed my whooping 45k just for kit.. will be shelling out another 2k for RC and and some 1k for insurance but that all will be done in another coupleof months once the norms match..

alloys.. yep i went to karol bagh yesterday for alloys.. seen 17 inchers plus 205 kumho all costing me some 25k.. i guess next month will get those..

seems like you din't search the market well enough, Bedini Kits are Euro 3 ready, Sold by Shrimanker in Okhla. They are authorised fitters by TATA. Any CNG system you got will void warranty unless offered by the company itself..Maruti as of now does not offer any warranty for CNG converted Cars, The only exceptions are GM Chev Optra,HM-Mitsubishi Lancer,TATA-Xeta and Marina( All these cars have Euro 3 norms and Euro 3 ready kits)
I hope you got the Advanced Timer or Lamda controller.

Plugs, I really don't know how effective they are, However cool air intake will def help, along with Free flow system.

OK.. i accept that i was a lil bit of a lazy *** over the weekend.. after comming home at 6 in the morning from office and after spending nearly 18 hours at office i was dead tired so. yes i did tried my level best..

about the warranty... saya motors will fit the KIT with all the warranty intact.. they said there will be no wire cutting this is a plug n play kit all they have to do is drill the boot to fix the cylynder,, rest the kit will be installed without much of fuss.. which will in no way void the warranty of my car.. there will be some certificate that they will provide... and they have given me shurity that the warranty will not be nulled after getting my car converted to CNG.. PLUS an option that if i wanna sell my car i can remove the CNG kit.. get the NEW RC done.. and sell it..

all i can do is HOPE that the person there wasnt bluffing..

I don't get it. The only reason people buy CNG over Gasoline is to make the car cheaper to run.

But by trying to compensate for the power, you're spending a lot more, just to match a petrol cars performance.

Even with all your efforts, how much gain do you expect?

And even if you succeed, what FE and maintenance would that add up to?

The rule is simple. If your car in a CNG, don't touch it. Use it the way it's supposed to be used.

i can easily recover the cost of the kit withen 9-10 month so after that its all saving ... and then with that saving i can spend that on my hobbies..

if i install a lambda controller which if i am right in guessing will cost me around 10-15k .. again i can recover its cost in another 2-3 months.. wont be a problem..

its all abut experimenting yaar.. just wanna feel the same power and pick up with CNG based engine. i guess thats worth it..

It is definately worth it, as long you consider it an experiment or rather, personal achievement.

But practicality has nothing to do with it.

Guys,

Is it safe to have a Free Flow exhaust on a LPG fuled car? I was told that its a little dicey to drive a LPG fuled car to run with FreeFlow exhaust.
