Wet kit hits harder.

ok...some one clue me in WHY a wet hits harder. I want specific reasons.

From my experience (can't say the same for others): 100 shot jets from my nx wet kit gave me 100+ hp with 10-12 mph gain. I guess because nx rates theirs at the wheels. 100 dry shot gave me around 75 hp with 7-8 mph gain. A 75 wet shot gave me the same gain as the 100 dry shot! I was so upset with the crappy dry system, I switched to a wet kit immediately. This was all on the 3.8 Firebird I used to own.

that just means you were spraying more nitrous in lbs per minute with the wet kit than the dry kit. Forget manufacturers ratings...they mean nothing. Power production from a nitrous kit is about nitrous flow, and tuning.
IMO kits should be rated in lbs or ounces per second of flow. Then you tune fuel for the desired AF ratio. You would then see that they are all very similiar.

If one kit is rated at 150 hp and you are getting 150 from it...and the next kit is rated at 150 and you are getting 100 from it...do you really think the nitrous and fuel are just dissapearing to the tune of 50 HP worth into thin air? Doubtfull...the likely answer is one kit is not flowing the same amount of juice as the other.

Hell...even wet kits compared to other wet kits have large differences in ratings.

I know when I was jetted for a 200 dry coming on at 3000 rpm and the bottle pressure was at 1175 psi...it hit HARD.

I cant wait to hit my 250 direct port though

it's that lean spike i get with my dry kit a/f goes to 14.1, loss of tq.

lean spike is not a valid reason....I am assuming each kit is operating correctly. If you are running at 14 to 1...then you are not tuned properly. That is the reason for your power is suffering. Maybe thats the problem here...maybe its just that people slap on the kit and spray away as it sits.


As for the 1175 psi...that doesnt make a bit of difference...because thats the pressure I drilled my jets to to deliver the HP shot I wanted for the dry stage.

I could have done the same thing by going with a larger jet and less pressure.

Again...97% of it is about nitrous flow and tuning. Jet size, bottle pressure, noid size, line size all will affect the flow of juice on a sliding scale with each other. All of these things affect power. The only accurat way to measure if one kit in fact produces more power would be to have the exact same tune, same noids, same lines, same activation points, and the SAME FLOW OF JUICE over time in PPH or some other volume measure.

To each his/her choice.
reasons why I like dry over wet:

1- I do not depend on a fuel noid. (which could mean the life or death of my motor)
2- All parameters can be tuned via pcm
3- Composite intake was certainly not designed to accept fuel, I have seen quite a few 200 shot backfires.
4- Still on the intake issue #8 and #7 start running at risky lean levels with 150 + shots wet. due to the flow distribution. Not so with dry, they do the opposite run a little richer.
5- As mentionned by 383LQ4 the actual jetting and power output of different systems are meaningless and can't be relied on, only through monitoring via Atap or similar and jet matching N20/fuel can it be tuned correctly, not so with dry, all it takes is to adjust via pcm for the size jet you're running.

Since my last posted times (April 04), I transformed the 5177 into a dual stage, capable of shooting 250 dry. No extra expenses the whole kit still only cost me $530.00.
Now compare that to a wet system shooting 200 wet safely, you'll see the difference.

Slow TA

you wanna make big horsepower im talkin 500+ go with dry. if you just wanna bolt on 100 shot car I would go with the wet. Ive raced people with the same shot as me only they were running nos and I walked them ugly. I agree when you start getting up to those big numbers it is hard to tune. I put down 293 rwhp NA and my 100 shot put me up to 410. almost 120 hp gain from a 100 shot of wet. explain that one

PREDATOR-Z

383LQ4SS explained it to you above. It is about "flow of nitrous".
Just calculate by flow how much nitrous is needed for a 100rwhp shot wet and you'll find that it requires the same amount in flow of dry. Nothing to do with the jet or kit ratings.

And guys...dont get me wrong...I am not argueing FOR dry kits and saying its the only way to go....its not. I am argueing that you should not base your selection of kits based on half truths. Understand the priciples of nitrous and how it works and you can basically set your self up with a very good setup.

BTW...my new setup is 150 dry first stage and 200 wet direct port second stage.

I'm more partial to dry kits. Easier to install, too
