What is the Difference Between Wet, and Dry

[Bocephus027]

I see kits advertised as a wet shot, or a dry shot, what is the difference?

Also what is a fogger system?

All above is correct, the only thing I can add is the foggers are better reserved for larger horsepower kits. They have better cylinder to cylinder distribution than a plate system, but at lower horsepower settings, the fuel jets start getting pretty small and are more prone to getting stopped up. For instance, on a 200 h.p. shot, you share this with 8 jets that are flowing about 25 h.p. worth of fuel and nitrous each and this makes for a pretty small fuel jet. On the "dry" systems, some use a regulator in between a safety solenoid and the main solenoid to reference the pressure regualtor and increase fuel pressure to get the extra fuel. I do believe that some also act like GrandsportC3 said. Clay

Few factory injection systems are wideband to the best of my knowledge ALL dry kits for otherwise stock systems handle enrichment through SIGNIFIGANT fuel pressure increases to make the injectors act much larger. It is possible with aftermarket injection to have the computer add the fuel, but on stock management vehicles the pressure increase means the fuel is delivered completely independant of the pcms control.

Injected cars can run wet kit too, plates or single nozzles.

Wet is can inverted whip cream and nitrous is going in your mouth.
Dry is can upright with no whip cream just nitrous.
