Team-BHP - How to Modify / Tune your car - 2

All this technical jargon and no actual help with the jetting and fuelling sizes? Keshav, I remember you having the recommended jet sizes document from my kit. How about putting up a scanned copy for everyones benefit? I think the most important thing for people to know about Nitrous Oxide systems is to know the safe limit to use on an engine and the recommended jetting.

Well GTO had put up a post on Modding and Tuning your car where he talked about modding the car in stages and what could be done and what not.

Nitrous:

One of the quickest approach to a fast car and a quicker approach to a will blow out before you release that nitrous button....

Have fun and be careful. Do not use nitrous on the street and be responsible drivers.

that made for some real good reading.awesome explanation.

Please be careful from this point on and I would never reccomend that you do this on your own

Jetting a nitrous system and fuelling is best left to the pro's as it depends on too many factors to list out here
Jetting can never be copied from one car to another as it varies as per the mods / fuel / fuel pressure / ignition system / strength of the engine etc
So go to your tuner and have him do it :)

I know this post may not have answered all your questions and I may not be able to do so in one go so I am taking the liberty to point you to some good material here

Would also add another point: Manufacturer reccomended jetting is a rough bench mark and not an accurate measurement of the jetting to be used on a vehicle.

Good info.

And, would people please stop calling it NAWSSSSS.........that's a trade name for nitrous oxide systems.

That was hilarious.. :uncontrol Reminds me of stuff like flammable NAWSSS, seven-speed Eclipses and MoTeC Systems Exhausts... NAWSSS is to nitrous oxide as Xerox is to photocopiers I think.

Quite true about the nitrogen and oxygen splitting part. I'm one who knows so much of organic chemistry I could tell you the angles of the bonds between the atoms of a carbon dioxide molecule.

Its just that if it was only oxygen which needed to be pumped in we could borrow a cylinder from the neighborhood hospital couldn't we? I agree with you also on that the nitrogen is what keeps it stable. But it is not just air being pumped in. It is a definite mixture of nitrogen and oxygen called nitrous oxide. Air also contains carbon dioxide, carbon monoxide and other acidic gases which are not of much significance. So calling it packaged air would be an insult to something so heavenly as nitrous power.clap:

Exactly, it was used only as a figure of speech, I'm not sure why everybody is being so pedantic about it ! N2O is just an oxidizer & not some magic fuel - at the end of the day you still only burn gasoline within the cylinders, just more of it because you have more oxygen (or air in layman's terms). And yes, N2O also cools the charge quite a bit, but for all intents & purposes its still 'packaged air'.

For the sake of being politically correct, we shall from now on refer to nitrous as packaged oxygen with a stabilizer agent or better still packaged air without any other impurities. :uncontrol

So it seems that not many people have tried NOS for diesel engines in india.

I doubt ANYONE has tried running NOS on diesels in India yet.

Our tbhpian from delhi Gaurev Prabhakar runs his Jeep using a scorpio engine with Nitrous too.

Check this out for more details..

Am sure brraj is going to follow suit soon.. :)

hey psycho is it advisable to hook up nitrous with stock internals?

Am assuming it is for the chevy aveo 1.4. with the FFE and a filter. My answer, I really don't know as I have never read up on the engine or worked on it.
