i read the sticky up top, and it had alot of good info, but it doesnt exactly answer my questions...and when it comes to boost i dont know much

what are the advantages/disadvantages of the dry/wet kits?...

i know what the difference is

why is one kit cheaper and whats the major differences in performance and reliability?...thanks

 

copied from the wet vs dry sticky

Advantages of the wet system
Tuning is less complex. The wet system is less finicky than a dry system. The wet system does not rely on the fuel injectors to supply the fuel nor does it rely on the mass air to compensate the added nitrous flow. So no reason to worry about a bad mass air meter, maxed or clogged injectors. You have the ability to run a dedicated fuel system to support the extra needed fuel demand. You can also run higher octain fuel in the dedicated raising the over all octain. Having the option of running the good race gas in the dedicated eliminates most of the concern of fuel solenoid failure do to bad gas causing the fuel plunger to swell.

Disadvantages of the wet system
Bottle pressure is more critical. Your fuel pressure always stays at a steady rate of flow. When the bottle pressure drops the flow rate of the nitrous drops. This changes the tune up causing the car to nose down on horse power and bog due to being to rich. A purge is more critical to keep the car from bogging on the initial hit due to the fuel being at the solenoid and not the nitrous.(air in the line) You are relying on another mechanical to supply the fuel. Some EFI intakes due not flow as well at certain hp levels with the wet system. In the case of a back fire the backfire is more violent due to the greater amount of fuel vapors in the intake. (There are always fuel vapors in the intake. Even naturally aspirated)

Advantages of the dry system
Bottle pressure is not as critical. If the bottle pressure is down the car will not loose horse power. It just simply will not make any added horse power. Purging the system is not as critical. If air is in the line the system will just not hit as fast and hard. In the case of a back fire the backfire is not usually as violent due to less fuel vapors in the intake. With tuning capabilities you can pull timing with out the needed accessories such as a timing tuner. No need to worry about fuel solenoid malfunction do bad gas causing the fuel plunger to swell.

Disadvantages of the dry sytem.
The owners tuning knowledge needs to be a little farther advance. Dry systems normally require a little more tuning and knowledge to adjust the air fuel. The dry systems are finicky in this area. You may have to upgrade injectors to supply the needed fuel that will be required from the injectors. There is a chance that the mass air meter could malfunction.(Not real common but I have seen it happen in person.) All fuel upgrades will have to be done with the cars actual fuel system.




Dry kits are cheaper because their are less components.
A wet kit will have 2 lines, 2 fitting, I solenoids, extra bracket, screws, etc...that the dry kit does not need

they will both make ~ the same power...there is no performance difference


A properly setup and operated kit will be reliable....but this is the real arguement over wet vs dry....I see neither as a better/more reliable.

They both have their place. It all comes down to the one the end user is the most comfortable with and can meet the tuning demands of the particular kit.

 

thanks for the info...where was that sticky?...

i asked these questions because i always thought about adding a small shot onto the mods i have now, nothing to big because i dont want to deal with a risk on internals and seeing i didnt want huge gains out of this, i didnt want to throw alot of money at it....

i read on small shots 50-75 injectors and pump dont need to be changed.....

 

sorry...It is stickied on another board we sponser..I forgot the thread here wasn't stickied

here is the link to the thread

The need to upgrade the fuel system, is going to be dependant on the amount of power you plan to make more than just the size of shot.

For example,
You have a bone stock car and want to add a 50 shot on a stock fuel system.....may not need to upgrade the fuel system.
or
You have a 550rwhp stroker motor and want to add a 50 shot on a stock fuel system......not gonna happen.

 

my basic jist, is i have pretty much a full bolt on car...and would be just looking for a little push....i wanted the simplest most reliable kit to give me what i wanted...thanks for the link

 

If safety and reliability are concerns then the dry would be the ticket.
