Nitrous...wet or dry ????

[v8killr]

I'm thinking about installing a system this spring and was wondering what people that have nitrous are running and why.I know the dry system is easier and safer to run but which is better.
Any input would be great.
Thanks David

It depends on what mods you already have and how much nitrous you are planning to use. Reading this article may help you decide.

Isn't wet a whole lot safer?

I'm in the process of getting the engine back,I have a guy here in nashville that's doing all the block work.I know the engine will hold it....i just don't know if i want to run it or not...

I'm going to think about it for awhile since i won't get the engine back for a month or so and it won't go in till spring.
Thanks for the replys.

sounds cool, but remember whatever shot you run its going to be "like" double due to the lil whiner that sits on top, cause NO2 is just another power adder. good luck

Dry is a whole lot more safer

I'm pretty sure wet is safer. With the fuel line tapped, you're going to get a better mixture. Since dry is sprayed directly, you might get an uneven mixture in the cylinders. Also, if your stock fuel load isn't up to the task, a dry system could end up with way to much nos and blow your gaskets a lot more easily.

A dry config would be easier to set up, but I don't think it could ever be safer.

One isn't any safer than the other. On some applications using a wet system may allow fuel puddling to occur. That is not a concern on a supercharged car like ours unless you install the nozzel in the wrong location, or start spraying at too low of rpms.

The advantage that wet has over dry is adjustability. With a dry system you can only change how much nitrous is going into the engine, unless you have the ability to burn a custom chip or use an EEC tuner to add or reduce the fuel supplied by the injectors.

With a wet system you can change the amount of nitrous and fuel indepentently by changing only the jets. I perfer the wet system it because it's easier for me to make adjustments. For example my car required a 75 hp fuel jets with 100 hp nitrous jet to maintain the AF ratio I wanted. So long as I maintain that same ratio of nitrous and fuel I can safely jet the power level up or down without reburning my chip.

Both systems require the same amount of fuel, it's just a matter of how the fuel is delivered to the cylinders. The best way to insure an even distrubition of nitrous and fuel to each cylinder is with a nozzel for each cylinder. This isn't something you can do on a stock supercoupe engine because of the canted in the head injector locations.
