Going to need some help on 2 Stage DRY
Going to need some help on 2 Stage DRY Ok heres the deal right now i'm running a single stage dry with dual nozzles.Now one nozzle is in the neck of my lid pointed to the MAF & the other is in the side of the lid pointed toward the front of the lid combined spraying 150fwhp.Now the reason they are split like this is because i froze my MAF with a single in the neck 170fwhp shot.So now i am going to go to another dry stage of 125fwhp which should give me around 220-230 rwhp?
So here my other questions:
Fuel System:
42lb injectors,Walbro intanke,hotwire kit?
Nozzle Location:
One in Neck for A/F/ and one in the side of the lid for the first stage asit is now.And 1 in the other side of the lid for the 2 stage
Spark Plugs:
Tr6's or would i need colder
Plan on running Dyno Tunes 2 stage window switch for stage controls
RPM Activation:
1 stage 3200-6300
2 stage ****-6300 maybe 4500-6300 and will be on a first gear lock out?
This what i can think right now.Car is Hot Cam,Header,M6 Car makes 352/365 on the motor on the Dyno
O P.S. For you guys running 2 tage what kinda improvements in E.T. adding a 2nd stage on to of you first?
Thanks Guys

What brand and size Solenoids are you using? Bottle pressure is also critical for total output on dry shots, more pressure=more nitrous=more power!
Fuel system, I have been running a 210+shot, Walbro Intank ($100) with a hotwire kit ($70), 42lbs Lightning Take-off injectors (bought for $10ea) and then tuned (free since I do my own).
Nozzle location...see my sig pic. Standard NOS 5177 plumbed into the sides of the lid (Stage1) and then a center mounted single inlet/dual side discharge brass fitting (Stage2). Remove the Air Filter when spraying to avoid freezing the damn thing!
TR6 Gapped at .030-.033", check and adjust as needed.
WS are for wussies
j/k. If you could step up to a 2Step, then you could wire it in to the WS and Nitrous, preset launch RPM, and then go from there. I think this would help you dial in your best ET's as well since you can progressively step the Launch RPM depending on track conditions vs. traction vs. shot size etc...

Thanx Cat,I think i might put a Nitro Daves Halo spraybar in instead of another nozzle,noids are Dyno Tunes 250hp big Noids bottle pressure is kept at about 950-1000psi

Sorry, I have been re doing my system, a new dry, dry, wet 3-stage. The dry is a new kit we may offer 'Ultimate Pro Dry', based on NX stg 6 noids and CF SS nozzles. Working things out and it's so far on maiden trip set a new best all time 60"er and a new best ET for this year on a single stage. Stay tuned. 
What kind of nozzles, ie: 90*, 70*, 45* straight?
I say stick with nozzles as you can adjust your a/f this way without affecting n/a tune. Other non nozzle methods have no way to adjust a/f without going into pcm. Close is good, far away is bad.
What do you mean you froze your maf? you mean the screen? I have 4 nozzles within 3inches of maf and dose not freeze MAF (3-straights and 1 90*). get rid of the screen.
I'll have more input once Iknow the answers above.
If you lock out 1st gear and come in like you said, a small shot can knock a 1/2 second off et and increase your mph quite a bit.
What is the shot in each stage? not sure I could follow above.

Nozzles are Dyno Tune 70 fan sprays.Not real sure on the Maf first full pass with system on the return road the car started braking up and sputtering real bad and we pulled the codes and they were for the Maf.So we then cleared them and once the car relearned it do the same thing put a new maf in and its fine.Maf also was descreened.Right now i have 120 rwhp spraying in first.Now what i am looking to do is have second stage come on in second and spray another 120.

Should be good to go. I run svo 42's, Ractronics pump and hot wire.
Nozzle Location:
One in Neck for A/F/ and one in the side of the lid for the first stage asit is now.And 1 in the other side of the lid for the 2 stage
This should work ok, as the 70* nozzle will be your prime a/f controler, just make sure a/f is good with both stages going. I have mine similar and it works great. Cat's set-up is somewhat similar also.
Spark Plugs:
Tr6's or would i need colder
Should be fine, I run em also. Mine are gapped at .035.
Plan on running Dyno Tunes 2 stage window switch for stage controls
RPM Activation:
1 stage 3200-6300
2 stage ****-6300 maybe 4500-6300 and will be on a first gear lock out?
I have my 2nd stage coming on right at my torque peak, that way you'll carry a higher average torque much longer through out run and you'll win more races compared to the all in one shot torque spike hits off the line.
This what i can think right now.Car is Hot Cam,Header,M6 Car makes 352/365 on the motor on the Dyno
O P.S. For you guys running 2 tage what kinda improvements in E.T. adding a 2nd stage on to of you first?
It really depends, on each set-up, but tou surely will be faster and quicker.
