Whats the pros and cons between a "dry shot" and "wet shot" of NOS?

Great question...I've always wondered, but have been afraid to ask..LOL.. Also out of curiosity,...Just how safe is moderate usage of NOS?? Would it work well w/a Magnacharger??

Here's some info to help you:

Dry shot
Pros:
Fueling is controlled by the computer via maf
Typically less expensive than wet kits
Can be hidden more easily

Cons:
Requires computer tuning
Requires injector upgrades in most cases
N/A tune will suffer

Wet Shot:
Pros:
No need for larger injectors
Minimal to no tuning needed
Can alter A/F ratio via jetting
Maintain your high hp N/A tune

Cons:
Typically more expensive than dry kits
No computer backup if solenoids fair
Possibility of fuel puddling in the intake

Now just to elaborate on a few points I'd like to say that either type of kit will require a fuel pump upgrade for even moderate shots. I know I listed a pro of the wet kit that minimal or no tuning is required. That's because some people fudge it and run a richer setup (via jetting) but in reality your timing should be adjusted in the computer for your particular setup. With a dry kit the A/F ratio and timing will all be controlled directly through the computer so more extensive tuning is required. Something else to keep in mind is that if a solenoid fails on a wet system you run a big risk of hurting the motor as the computer won't realize the change in A/F. Wet kits also spray fuel through the intake and there have been cases if fuel puddling in the intake and causing big backfires which have destroyed intakes, hoods, and even full cars. Either type of kit can work very effectively and everyone has their own preference.
In terms of nitrous and it being safe, well it's just like anything esle. If it's setup and used properly it's as safe as any other power adder. The biggest difference between nitrous and forced induction is that nitrous will be and instant jump in power (assuming no progressive setup) which will shock the motor. Since forced induction setups are more relative to rpm the increase in power will come more gradually. With proper education nitrous is perfectly safe.
This is a good starting point. If anyone has more specific questions ask away.

Will agree, solid post. I have a question for you. I have a little race coming up at a 1/4 mile drag strip against an unknown RX7. I would like to have something set up for the 2nd and 3rd run if he is just killing me. If I go with a Wet kit as you have indicated requires no tuning. What would be a good kit to add to a pretty much stock 2007 C6? 100 shot, 150 shot?? What you think, this race is just a ego trip, from this guy who was talking all sorts of game at Christmas party so want to increase chances of taking him!
