I'm considering adding a kit to my coupe.
Did a search couldnt find any posts on this...
Whats the main difference between Dry shot and Wet shot?...
I want a kit that i can take off when taking my car to the dealer for service... What kit do you guys recommend im looking for a 50-75 shot.. nothing more... also would the nitrous do alot of damage to the engine? I know nothing of this subject so any info is appreciated. Thanx

 

This is a long post

Wet nitrous systems utilize a fogger nozzle to combine the nitrous and fuel together before entering the intake manifold...The nozzle is usually positioned before the throttle body, as this allows a positive shut-off)...A dry nitrous system introduces nitrous through the injector by raising pressure in the fuel rail; this is called nitrous pressure...In general, the compound works like this: oxygen molecules are key to power production...Nitrous releases free oxygen molecules within the compound, adding to the potential of the combustion process...More free oxygen molecules equals more power...So that's how nitrous works

Benefits and Drawbacks of Dry: Safety margin of never injecting nitrous until there is sufficient fuel pressure and flow...This means that the system is subject to the capacity of the fuel pump and its ability to flow sufficient fuel at the elevated pressure level...Also, injector size is another deciding factor in the amount of power that can be delivered...Of course, just because the system will only work when there is sufficient fuel pressure does not mean that you will experience a huge lag in power- it is most likely that this lag is measurable in fractions of a second, and this is the safer choice

Benefits and Drawbacks of Wet: Immediate response, since both nitrous and fuel are introduced together as a mixture...This system does not rely on additional fuel pressure...This is also easier on your fuel pump and injectors...However, nitrous could possibly flow independently, should the fuel line or fuel filter get clogged

So I hope that helped...By the way, nitrous is NOT a fuel...It is an oxidizer...You may have seen the scene in "The Fast and the Furious" where the Tran clan shoot the Eclipse to Hell and Vin yells "NOS!" before it goes up in flames...Actually, the odds of that happening are pretty slim...Were you to spray a match from an open bottle of nitrous the match would most likely blow out...That doesn't mean you should try that, by the way...I'm not endorsing exposing your system to open flames

As far as kits, Nitrous Express is a very easy to work with and popular choice...NOS by Holley has been around for a long time and is pretty easy to work with...ZEX is the easiest kit to install, from what I've heard...All these companies offer remote bottle openers and packages to upgrade to kits that include purge valves, gauges, and bottle warmers...Nitrous needs to be at an ideal temp to work correctly...Vaporized nitrous is at around -129 degrees F (boiling point of nitrous oxide), and the warmer is automatic and keeps the bottle at the correct temp

As far as engine damage, most motors can withstand 40% to 50% of power increase...This does of course depend on the original power output and the engine displacement...The big issue is the strength of internals...Were you building a high horsepower super- or turbocharged motor you'd want forged internals, and nitrous is forced induction as well...It's really your call, but I always recommend upgrading internals (rods, pistons, head gaskets, studs...) if you are going to, essentially, abuse the engine beyond what was intended as far as everyday wear and tear...As far as using nitrous correctly, you REALLY need to take this your ride to the dyno and tune the car for nitrous use...You need to make absolutely sure that the air/fuel ratio is ideal...No need to risk detonation...Custom tailoring the fuel curve is essential...As another note, when using a wet system, hitting the button too early can result in backfiring, so please tune the car around the usage and get to a dyno

WOW SnM thanx alot...
There is some stuff i dont understand...
So your saying the Dry shot goes in with the air? like through the air intake? and the wet shot goes with the gas?

 

You said you recomend the Dry shot better for the AT G coupes correct?

 

Save ur engine and weight for the TT.
