Apart from great pickup,good mid and top range, they also compliment with superb fuel efficiency, Which is approx. 250-300 km for Swift and 200-225 for SX4 (Both have 12kg cylinder) and max I got was close to 400km in Swift on NH1.
Now I am keen to install K & N filters (conical types with intake pipes) on both of them, also installed the same on my cousin's Xeta (again running on CNG) and it changed the car performance a LOT. But going by Gangsta logic doesn't appears to be really a good option.
@gangsta: Could it be possible that Green cone filter is not compatible or K & N is better with CNG, or maybe its Accent or your Lambda which might not be compatible, because I have read some previous thread where people are driving with performance filters with no problems at all. Please advise as I might go for the conversion tomm. itself.
As per CNG meet, count me on for it :-) |
lol you are getting a super mileage in your swift and sx4 , my friend's alto also don't give that much mileage on CNG (A slow driver).
Well..!! for the CNG meet you are most welcome for it mate
now coming on to the lambda in Accent first. In the month of feb, 2008 i had installed universal twin conical green filter and at that time i had cng installed in accent with no TAP. It's been a long time that i have cng installed in my accent and on that time no lambda or tap was available in the market to increase the performance of the car. then in 2 months or so , i don't remember how much time, i had installed TAP in accent and a kick after 1500 RPM... then also i had no problem with the car with green filter. Then the problem came, tuning was going out regularly because i'm a hard hitter of the gas (Infact I was). then again after lambda installation the tuning was going out then that guy asked me to change the air filter because he had a talk with the lambda dealers regarding this, they also told him that it may not be compatible with the performance airfilter. I changed the airfilter to the stock and it is working fine. It is running fine without any panga.
If it is working fine in your friend's car then may be this combo is not compatible. I don't know the technical reason Why it havnt worked with performance airfilters in my car? Also, my friend's OHC with the same green filter, lambda havnt worked in his car too. He had to change it to the stock.
Now coming up to the Performance airfilters in CNG cars. There is no use if you will install a performance airfilters. This is because of the fact that CNG uses less amount of air to burn unlike petrol. Performance airfilters are good for petrol where you need good amount of air while revving. I'm absolutly sure about it that it's just psychological and nothing else. I don't have headers and manifolds changed in my car, so again i don't think it will be a drastic change in the performance of the car unless you revv it hard, it will just make the car a bit of free revving. that's it. it also depends what type of headers and manifolds used by your friend. you can find it in some threads for exhaust on the forum. But Performance airfilters? Nah!! Guess what? Stock Airfilters infact the airfilter assembly is acting as a CAI. where is the intake opening for the stock airfilter assembly. You can get a hot air in performance airfilters as it is sucking air from the engine bay. You may go for Cold Air Intake. but that too no use for CNG cars just because of the fact cng needs less air. In short CNG is getting enough amount of air from stock airfilters and that too cold air, means much better performance. Simple Logic
now WHY THE HELL I HAD INSTALLED PERFORMANCE AIRFILTER WHEN I WAS RUNNING IT ON CNG? 1. i wanna do experiment.
2. I do have a frequent visits on highways and on highways, i need better revving.
my car is running better with stock airfilter on CNG. But i miss the petrol revv. This is a fact that if you will pull your car hard on petrol after 100 kmph - 160-170 kmph, performance airfilters do work much better than stock airfilters.
HELLO DELHI CNG GANG INTRESTED IN THE MEET?
