NOS System!!!
-
Hi people,
i recently seen an advertisment in Wheels(asia) June issue magazine that they are selling a NOS system for cars to boost up 100 horses or more for about $1400...
Just wonder if this is legal in singapore with the strict LTA??
ANyone have an idea?
Another thing is that does K&N filter helps in saving petrol?
or are there any good proven quality stuff in the market that help to save more fuel..i am currently driving a Nissan sunny s.saloon 2001. Thanks. -
You find the your engine's combustion chamber too smooth for your liking?

Anyway, not trying to discourage you from getting one, but you have to do some research before deciding. Here are some things you might like to know:
More horsepower is going to put more stress/strain on the engine any way you look at it.
The nitrous itself only changes the operating parameter of the engine. Those conditions, if not accounted for, will cause problems-potentially disastrous ones.
With all the oxygen introduced (N2O contains 33% oxygen versus 21% in normal air) you will be running incredibly lean instantly without compensating with the correct amount of fuel. Aluminum, forged or otherwise, does not like to see this for very long.
The advantage of using nitrous is two fold. 1) It introduces more oxygen into the incoming charge in a form that initially does not occupy too much space. 2) Upon vaporization it lowers the temperature of the air causing a denser charge entering the cylinder.
To take advantage of nitrous you must have a few other elements in "the system". In order to help vaporization, just as in vaporizing gasoline, the nitrous must be in as small a liquid droplet as possible. This is done with the nozzle or "fogger". The atomization of nitrous into smaller droplets increases the surface area to achieve better evaporation. Heat is absorbed in the vaporization process lowering the surrounding air resulting in a denser charge (packing more air (oxygen) into the cylinder than at the higher temperature). The denser charge and introduction of additional oxygen into the charge allows for the oxidation or burning of fuel. This is the catch.
Additional fuel must be supplied to prevent going dangerously lean. The whole combination of additional oxygen, denser charge, and denser fuel results in much more
force being exerted on the piston per power stroke (torque & horsepower).
Before you do anything to your car, make sure your engine is in good condition. Second, find out as much as possible about NOS, then buy the kit that suits your needs. And if you are not comfortable installing the kit yourself,don't risk it, have a shop put it in. Also DO NOT run more than 100hp on the stock fuel pump, it is already maxed out!
Hope that helps.

illegally modified so u have to tow it lor. about the saving fuel question u should ask Praetorion111*
anyway i included this picture of NOS
*sorry i dont know how to spell his name

Oh I just noticed, if you can fit a NOS system, you want to fit it in your 2001 sunny saloon?

Better filter do save petrol.K&n is quite a gd air filter.
Heard frm my friend who is driving the new sunny,said that E68 do help to save pertol as well.U might say around for more feedback. -

By the way , there is alot of NOS type ranging from 45 horses to 1000+ horses(only for extensiosly modified cars).well for your Nissan Sunny 1.6, the only version available is Wet manifold type system or Sportsman Fogger depending on how much horse u want for more info go to http://www.holley.com/HiOctn/ProdLine/Products/NOS/GenInfo/KitList.html

Heard of a drop in NOS which is like adding it into your fuel ... its aquaus type ... it charges your fuel ... dunno how effective it is or is it a hoax ...
But if you want to power up your sunny i advise you to consult experienced machanics ... they will tell you to replace your air sensor, ECU and install a open pod air filter as well as take out some things from your car ...
as for my Sunny i am keeping as stock as possible
errr ... with a but of mods 
to keep up with those tiong chiaz ... install an open pod and a fuel charger will do the trick ....
Good luck in your quest for a better Sunny...
Always have sunny side up for better insperations* -
think if get caught car will be confiscated
-
It is actually being sold in Spore.... Maybe it is imported for racing purposes and not streets.....Dunno whether it is illegal or not... maybe one of u can call up this number and ask 65665912...

Saving fuel?? A cheap way to do it is to tune down the combustion ratio.... BUt ur car will not accelerate as well as be4 lor.... dun reallie bother wif those fuel saving things.... I personally think a bit waste of money lor.....
-
One of my mates had his civic esi modded real heavily, everything you can think of, suspension, ECU,...the works, yes even NOS, its a blue tank in his boot. Even had an inconspicuous looking fire-trigger button(the type that looks like its for firing missles). Anyway he sold his car already and moved to Oz, bought a 180SX here specially for his drift sessions and a celica for his travel.

Air/fuel ratio

If you tune down the A/F slightly you will run rich which would give you better torque and HP at WOT, meaning your car will accelerate better. It also means you will burn more fuel. You need to tune up the A/F slightly to give best economy.
-
if your car doesn't come with extra gadgets and you don't intend to, tuning is not a job for you. Anyway, tuning takes effort despite of a recommended ratio.
NOS is illegal and it comes in charges, not boosting 100hp till your COE expires.
Judging from your car, the ways to keep fuel consumption low include:
1) wash car regularly (8-10% of fuel saving)
2) keep rpm low, drive smoothly.
(addictive hardly work) -

define "tune down".Originally posted by brisance:If you tune down the A/F slightly you will run rich which would give you better torque and HP at WOT, meaning your car will accelerate better. It also means you will burn more fuel. You need to tune up the A/F slightly to give best economy. -
By means of an EMS or a fueling management system such as an SAFC2, reduce the A/F ratio. i.e. bring it further from stoichometric 14.7:1 towards a rich burn limit.Originally posted by tailslide:define "tune down".
