There might be one already here, if you searched Nitrous instead of NOS.

I wouldn't even consider a dry set up...a 50 shot wet one is a possibillity in the future for me.

I would definately reccomend a wet kit as the injectors are already taxed enough keeping up with the turbo.....one thing to remember is if you spray on a FI vehicle you will pick up more than the rated HP due to the cooling of the intake charge

I’ve asked before and don’t see why you can’t run a dry-shot, then adjust your tune (i.e. fueling) accordingly. Why do you need the fuel portion of a wet stage kit (baring you have enough injector overhead) when we all have sophisticated EM platforms which can add more fuel at any given condition, like at the onset of nitrous spray.

Simple example, UTEC with spare solenoid trigger, firing nitrous (dry) solenoid at 4,500rpm and 18psi, while modifying nitrous map for additional fuel at +4500 rpm. Of course I haven’t tried this, just something I’d like to do one-day when I need another motor

This is why. Most people don't have enough headroom with their fuel system to accomodate the n2o shot and run the a/f ratio they want. At the same time, most people run richer a.f ratios when on the juice then when not which then makes it so the fuel system has to flow even more then it would normally for that extra amount of o2 that's going in. A wet shot makes it so you don't need to get new injectors to run n2o. It's also a lot easier to just switch the jets then to adjust the fueling of the tune. I ran a wet shot for a while, and ended up switching to a dry shot. It was mostly because I didn't like injecting fuel into my intercooler.

Dry vs. wet depends on how much overhead you have in your injector flow, and whether you have EM that can manage injecting more fuel hen the solenoid is triggered, like a UTEC or Hydra. If you're already planning to upgrade injectors for other mods (turbo upgrade, exhaust, intercooler) then it is possible to just go even bigger to allow for adry nitrous system. OTOH, if you're just doing nitrous, or already use all of the flow you can get out of your injector style (ie. 850cc for an EJ20), or aren't using EM that will inject the fuel for you, then you'd want to go for a wet system.

Deciding which one to use should have nothing to do with if the car has a turbo or not. Wet and dry shots are basically the same thing. They both inject nitrous into the engine. The only difference is that with a wet kit, instead of just injecting n2o, fuel is also injected. The injection of fuel compensates for the amount of n2o that's injected, and makes it so fuel tuning isn't necessary in many cases. There are many ways to run both types of kits, and which kit/setup you choose can depend on many things. Here are a few....

1)ability to tune(change timing, fueling...)
2)fuel(octane level)
3)fuel system capacity
4)fuel system requirements
5)price
6)size of shot

peace
