I don't know if there is a diffence in HP between wet and dry NOS. I also don't know which one to put in my car (1990 Crx) help me out

 

wet usually goes directly into the intake manifold and dry is usually into throttle body or intake. i would go with dry myself unless you got a built engine. hondas seem to like dry better

 

uh i dont think that is correct......
dry- nitrous only
wet- nitrous AND fuel

 

the dry goes into the intake, and the wet goes into the fuel

 

Dry nitrous means that only nitrous is injected into the system.

Wet nitrous means that nitrous and fuel are injected into the system.

Dry uses one solenoid for nitrous, wet uses one for nitrous and one for fuel.

 

Then wouldn't wet be better? since it compenstates for the extra air with extra fuel and therefore helping stop running lean?

 

A wet system uses both NOS and fuel. Depending on the HP shot you want to ensure that your motor is in perfect working condition. NOS doesn't care if your motor is brand new or 10 years old it will destroy your motor if you don't respect it.
In my opinion a wet system is better than dry.

 

How does a NOS Plate system fit in this picture? Is that a wet or dry? What is a plate system anyways? heh

 

Plates (v8 style) sit between the intake manifold and the carberator (sp?) where they spray into the intake.
