Will i blow it sky high or what??
$200 for a dry nitrous kit is just a damn good deal lol.

I see nothin wrong running it to maybe provide some spool? :dunno:
I wouldn’t trust it until I build up the motor a bit at least…search some
popular sites to see what people think about it.

I talked to a guy at Holley (NOS) and he has a 240. He ran a 25 shot which amounted to a 50 HP gain because the car was turbo charged (cant recall how he said that worked but still, he works tech for NOS i figure he knows what hes talking about)

so based on that you double the rated hp if boosting?
so then, if you get a 150 shot, you will in actuality be getting 300hp shot? that doesnt make sense.
if it is true though, you could have a 1000+ hp sr EASY.

What nitrous does is baically super cool the intake charge to allow more oxygen into the combustion chamber and nitrous also has a higher oxygen content that the atmosphere , that plus more fuel you get more power, obvously you have to have the formula right though.
hmm, I can kinda see how when a turbo is packing air (aka boost pressure) into the combustion chamber it is able to pack more in as it is even cooler, if thats make the Nitrous have double the effect but I dont know. the only logical thing I could think of is that
So basically it has something to do with the Nitrous cooling the whole system making it more efficent thus seeing a larger than normal power gain on such a small shot.
Nitrous is a very good tool, I have used in on a few cars, but it is finicky and some times a big pain in the ass.
I dont think though it would be the same for all nitrous shots though, cause as got boost said it would then not make much sense

With more O2 your computer will put in more fuel? I guess if your are running a SAFC or some type of fuel managment you can just dump more in when you hit the nos? Any one konw more about this its intresting. I also saw on dream car gradge or sompthing that a wet system is alot better then a dry. but is more complex to install.

A wet system you add a certain amount of fuel via extra jets, the fuel gets mixed with the Nitrous when it is injected to better mix the fuel with the incoming Oxygen which allows it to burn better. Bad thing is if the fuel ends up puddeling in the intake tract you will get a back fire, which can be very bad. blown up intakes, somtimes even intake manifolds (usually the plastic ones like on Neons and Jettas for example–two cars I have seen the backfires first hand)–but not usually the welds–lol and of course you passenger side floor will never fall out due to Nitrous use lol
the dry system your cars computer does infact sense the extra o2 being added and compensates for it by uping the injector duty cycle. the dry system is limited by your cars stock engine management system and stock injectors-so too much nitrous you wont really know it until its too late-well thats if your unlucky-. The AFC from what I know does no such thing-it is your stock ECU that does all the adjusting.
Also please its nitrous not NOS. NOS is a brand Nitrous Oxide Systems. Nitrous kits are made by many companies Holley/N.O.S, Zex, Nitrous Express, and many others.
BTW Nitrous is not magic its basic Chemistry

Yeah, right now it has a 100hp jet, that would be the first thing to go lol, i’m just looking for a little thump throught the first few gears, something like a 25HP shot would be prime
thanks alot again guys!!

I would personally use the nos for an intercooler spray if it was given to
me for cheap.

those are for dyno queens only they do nothing when driving at normal speeds.

yeah the only thing I see wrong with an intercooler sprayer is that Nitrous is not cheap, here it is about 40 dollars to fill a 10 pound bottle.
You would go through it really fast. For an intercooler sprayer I would just rig up the windsheild washer fluid bottle and a few garden sprayers–kinda like what SCC did.
also if the kit was cheap I would be sure everything is in working order, fittings, lines not clogged, solenoids working properly, etc etc. A

Buying off one of my best friends in halifax, he bought it off a guy who was desperate for gas and insurance money, and it’s empty, the guy took my buddy for a rip and they emptied it lol, so everything works i assume.

it’s probably much like a turbo itself, in that its performance enchaning properties are nonlinear. ie. for the first little while (like the first 25hp) you get a 2x gain because of the turbo, but as the spray increases the efficiency decreases and your start getting a 1:1 gain.
I would think the amount of boost you’re running would matter as well. and and your elevation and all that jazz.

nitrous isnt for amatures, ive seen how u drive , youve got a heavy foot
oh whatever u do , dont hit it more than three times or your floor pan will fall out and youll blow the welds on your intake, then torreto and the mad scentist will have to rip apart the block and replance the piston rings u fried, but then the cops will show up and you can save torreto and get in his good graces , get shot at by jonny tran, become his mechanic, boink his sister, drive a cool supra, buy your own shrimp after race wars, save vince from getting shot by a crazy vigalante trucker, race torreto, let him get away, run from the cops , drive around in your magicly appering 3000gt, almost get busted by the cops, get saved by a hot chick , buy a skyline, drive to miami , meet upp with ludacris , go back to work for the cops, and boink another hot chick …
see nitrous has many advantages, not only will u make everything around you a blur when u hit the button, itll make you cool and everyone will love u for being so fast and furious :lol:
