Which Car - CNG Installation

[invincible7]

Ok Guys, i want to know which is a better car in terms of overall performance and realiability for installing CNG kit.

By performance i mean, the car should be not very sluggish in lower gears with AC. this is the reason i am not listing any small/hatchbacks here.


Baleno, Accent(which models), Honda City (Vtech/1.3/1.5), Lancers, Icon(1.3/1.6).

Cheers.

I guess the CNG kit for the CITY VTEC Will be an insult to the cars performance

I think if u can get the OHC , go for the 1.5 one, install a CNG

I think that should give decent efficiency and the performance drop wont be too much

abhinav yaar,

I have seen Honda CRVs with CNG kit

There's enough Toyota Qualis 2.0P with CNG in Delhi as well.

Sorry bro i would like to differ your POV here, an OHC VTEC/NON-VTEC with a TAP/ FFE/ CAI will perform better than petrol.
I have an Ikon 1.6 on CNG with TAP and it performs better than petrol. The only problem with CNG is initial lag in the lower rev range till about 1500RPM-1800RPM which can be sorted out with a custom designed header.
Unfortunately CNG is looked down upon as an inferior fuel, which is very sad to know when its benefits surpass that of gasoline in most respects. I have posted this statement before aswell that turobocharging an engine on CNG/LPG/Diesel is far better than one on gasoline in terms of performance gain.

All the cars mentioned here will perform good on CNG but as much as i have seen and experienced with these cars, Baleno is the best on CNG in terms of performance.

Pick a car with plenty of extra power and torque because you will lose quite a bit after conversion.

For example, a Palio 1.1/Maruti 1000/Ikon 1.3_OHV are all bad choices because they are underpowered as it is.

I would like to add Corolla 1.8, Accord 3.0 iVTEC, Skoda vRS, BMW 316i amongst a few others with CNG. In delhi there is a CNG filling station at Kalkaji/Nehru Place and if you go there at 11.30pm-1.00am you might catch these big boys there, i have seen them there quite often.

what abhik is saying is right. CNG has a higher octane value than gasoline and hence better performance with tuned up engine. But you need right kind of settings and installation. TAP is absolutely necessary to negate pickup issues.
But i'm really curious to know that what would be the performance of an octavia vrs on CNG, i dont think it will remain the same unless it is a sequential kit installation.

The vRS was being fitted by the same guy who fitted my car so coincidently i was there when it was being done along with the BMW 316i.
A bigger kit comes for cars over 140BHP so even if you dont get seqential injection, the bigger kit wit a TAP or Lamda(depending upon closed or open loop operation) will give equivalent performance as compared to stock petrol, and anyways Skodas come with 4 point spark plugs which further help effective combustion of CNG. The owner after taking a drive after fitment said he could'nt make out any difference between performance on petrol and CNG even when he switched fuels on the go.

accha abhik tell me onething. I have this tomasetto kit installed on my OHC 1.5, got it installed in Tilak Nagar. There's a slight drop in performance in CNG mode but only slight. I'm now planning to make it as good as petrol mode. So would installing a TAP will take care of the whole issue or should i have additional things also?
and how should i find out that my current CNG setup is in open or closed loop because if its in closed loop than i would prefer lambda as TAP would be useless in this case.
and from where did u get your CNG installed?
also i want to get rid of this fluctuating ideal RPM which occurs sometimes.

TAP(timing advancer) would make a lot of difference in performance, infact you might even see better performance than petrol.
Go to your dealer and enquire about the kit, most kits are installed in open loop operation where TAP does good and Lamda is good for closed loop ones.
TAP would be for Rs1000-1500, they come with 3 settings like a tuning box and have 3 remaps(dont confuse it with ECU remaps which play around with AFR signals etc,its just for timing ) as option.
I will PM you my fitters details.

Oh God CRV's. Why Do People Buy such cars when they cant fill 'em up and run them

Vtec Will always feel insulted bro.

Gosh, I thought 3.0V6 and vRs's owners bought the cars for performance and not looking at efficiency, even if they can get great performance installing other components with CNG

[invincible7]

hmm so i think i would start my search for used baleno or city to get this operation completed. I was willing to go for a new car (Swift VDI), but the increase in fuel prices have left me with no choice at the moment.

I head about Lamda and TAP out here and also on another thread which talks about performance mods for CNG cars.

Can anyone guide me from where can i get more information on this and where to contact to get it installed in Delhi.

Cheers.

@invincible ill PM you my fitters details, he is a person with excellent knowledge about CNG.
