Default CNG + Turbocharger

I know most of you will have the following Reactions but still i am very keen on knowing the Technical Implications of installing a CNG Kit in an Octavia RS, so please be kind enough to shed some Light on this topic. The Pros, Cons, Modifications required to carry out such installation.

Is it possible? Definitely Yes.
Would I recommend doing it? a BIG NO!
For one simple reason that Skoda/VW engine parts in India cost a BOMB.
If you still want to go ahead,
You will need a sequential CNG injection kit which should be good enough for 175-180 bhp and the fuelling should be pucca. Run a turbo engine lean is something which will make you cry tears of blood.

Yes I do have the above reactions. CNG? on a RS? Why? the 5 RS price rise? Turbocharged cars as far as I know dont run lean. running a TC on Gas is not at all advisable.

Better solution, sell the RS and buy a Octy TDi then Pete it.

Yes sir it is, I would have thought my statement earlier was legible enough but still I'll reiterate, he runs a LPG Baleno with a Turbo!

IF you have full control over the mixture I don't see why there are any disadvantages? CNG has an octane rating around 110-130 (this high variability is one of its disadvantages though its still higher than petrol) and burns much cleaner. You can easily run 5-7 degrees more ignition advance at peak torque keeping everything else the same. This translates directly into a 5-10% increase in torque.

As far as technicality is the factor, basically anything is possible. Pros...might save fuel cost. Cons - a lot of work. Has anyone done this before?
Availability of fuel partucularly on a long drive can be a problem. Even finding LPG is difficult.

Hi Arpit, you have a great car and why do you want to have a CNG kit for that? RS is to have the pleasure of the drive.. you need to feel every sec of what you spend in a turbocharged car, if you are planning to save the fuel and want to do something wakey then do it on some other small size car and not on a India's fastest car. I dont want to see an RS in Pics of weird and wacky mod jobs thread....

Turbo + CNG a very very good option. My CNG fitter fitted a vRS in front of me and it runs like a bomb! The owner had a BIG smile on his face after a test drive after CNG fitment.
Google will also help you and so will Wikipedia.

You would need a ECU Remap, to negate the extra Air reading...!

@ Nitrous: I know Skoda parts are expensive in India, but the recent fuel Price Hike has made Driving such a powerful Car very expensive on Daily basis, and what is the point of having a good car if you cannot enjoy the drive, so i was thinking if there was any way that i can get my car fitted with the best CNG kit and enjoy my drive without any penalty on performance.

@ Abhik: I have gone through almost each & every post on CNG before posting this topic and havent found anything useful for me that is the reason why i posted this thread. Thanks.

or you could try and get a standalone ECU, and keep the stock ecu stashed away in case you need it later.
