wet or dry nitrous

ok you might already know this. but here are the gigest drawback for both systems.
wet kit
1. fuel puddling in the intake ( FI intakes are not designed for fuel mixture to pass. so sometimes you get puddling)
2. inconsistant mixture from cyl-cyl
dry kit.
1. running out of injector. ( this is because the dry kit uses the stock injectors to add the extra fuel. and at larger "shots" they just can't handle it)

wet v dry is a personally thing. decide for yourself.
For me a wet kit is what I know and what I like I just use my head and keep the jetting size down a lil.
If you go wet you will need to get a fuel rail adapter seeing as how 04's don't have a scharder valve.
I'd also suggest either getting a tuner with 2 tunes or a flip chip. 1 for NA and 1 for n2o.
Have fun happy spraying.

I would say wet. Unless youre planning on being a complete a-hole about it and doing nitrous burnouts and/or going over 125 shot I dont see where puddling should be an issue. I have checked my plugs twice and didnt see any evidence of uneven burn.
As someone already mentioned if you want to go that high with a dry shot you will need bigger injectors and possibly a better fuel pump or a Kenne Bell Boost a Pump.
Most of the speed shops I went to preferred the wet kit so I took their advice. I havnt had any trouble and I have emptied more bottles than I can count.
As for the tuner I am using the 87 Octane tune on my Superchips handheld. I had the spped shop that installed mine call them and ask if the timing had been advanced for this provided tune and they said it had not. I wanted to keep it due to the gears and automatic shift edits. No problems there. Assuming that tuner has a provided 87 Octane tune you could call Hypertech and ask them about the timing. I had them throw it on the dyno after the install to ensure the air fuel mixture was not lean as this is where you will get into trouble.
I did however just purchase a used Predator so I can get it professionally tuned for both NA and N2O.
You will need to get one step colder plugs and always run premium fuel while spraying. Also if yours is a manual I would highly recomend a window switch. You dont want to miss a shift while spraying. That could get really ugly. Basically just respect it and you shouldnt have any problems.
With those 4.10's and DRs I can tell you youre going to have a stupid grin on your face every time that bottle is open. Got Torque?

A dry kit is really better. However, for a non-race car, especially a mod motor, I would get a wet kit inorder to keep it safe. With a dry kit there are a number of factors that could easily cause you to blow up....or at least burn a piston or toss a rod. With a dry kit you need to make sure that your fuel system is perfectly operational, that your injectors are sized properly, and theat your injectors are perfectly clean and operational. A wet kit is more forgiving and allows you to run a more reasonably sized injector which will give you better drivablity to boot. Hope this helped.
I never said the dry kit is better. all i am doing is pointing out the downsides of either system.
both systems have dangers, personally I rather use a dry kit or a kit like the NOS nozzle.
as long as your injectors are sized properly I believe you will have less problems with a dry kit.
90 percent of the failures with a dry kit is due to people maxing out injectors. run big injectors problem solved
