Nos kit wanted to consult everyone

I am going to buy this kit tomorrow if all of you think its a good deal.
It is a NOS brand kit. It is used. It is a single fogger wet system with upgraded cheater solenoids. It comes with a purge kit and bottle blanket. What all do I have to check and make sure is included because i don't wanna get boned for $250? Do you think a used nos kit is worth buying? Do you guys think all that is worth $250. I don't know if the bottle is empty or not so lets assume it is.  

Well nitrous is pretty hard on a vehicle from my understanding, and having an A/T doesn't help.  If you plan on using your NOS regularly I would add a transmission cooler first.
 
Price wise, look up the kit on the net, compare prices, and compare what comes w/ the used one and new.

x2 on the tranny cooler. I know nothing about nitrous, but I would try to limit the pressure so less is sprayed. Try and limit it to a 25-50 shot to keep the stress down on the internals. $250 sounds like a fairly good deal.

whats a good brand of tranny cooler? will an ebat tranny cooler work? and a couple people on this forum said it was alrite to run a 75 shot on stock internals

I'd stick to a 60 shot max on an F22 motor.  A 75 shot would be fine, but I'd play it safe.  The shot is limited through the jetting or orifice (pill), not bottle pressure.  You should add a bottle heater to get a more consistant bottle pressure and also to extend bottle life.  The sudden drop in bottle temperature from spraying causes thermodynamic strain and weakens the bottle over time.  The heater helps lessen this effect in addition to the pressure benefit.

My recommended N2O setup for your F22:

On/Off switch
relays to combine functions to 1 switch
fused power feed for heater
WOT Switch
Window Switch
Bottle
Bottle blanket
Bottle heater
Bottle Pressure Guage
Pressure limit control
Remote bottle opener
35, 50 & 60 shot pills or jetting
Purge system


Setup:
On/Off Switch - When you turn on the switch, the bottle opens, heater energizes and activation controls arm.  When you turn off the switch, the bottle closes, heater shuts down and controls shut down and lock out the solenoids.

High Bottle Pressure - When the bottle pressure reaches an adjustable high limit, the power to the heater is inturrupted.  This is the effect.  In reality, the pressure control system should be fail-safe so the relay would be normally open and energized to close when the system is turned on via the on/off switch.  When the pressure gets to the high limit, the relay is opened.

Spray activation - WOT and Window switches are combined in series so that either can prevent spray discharge.  This way, you have to be in the right rpm window AND have the pedal to the floor.  This will prevent overleaning due to partial throttle activation and also so the spray stops automatically just before a gear change ...... and so you don't kill the motor by spraying at too low an rpm ..... I'd keep it above 2800 if I were you.

Purge - This should be powered and controlled completely separate from the main system controls.  The reason is that after the system is shut down and the bottle is fully closed, you should purge the pressure from the system.  This will prevent unnecessary wear to the N2O solenoid, line and bottle valve hardware.  In addition, a quick purge shot before activation will ensure a consistant spray and A/F mixture.

Thanx a ton folklore and everyone else. So folklore you don't think i need a tranny cooler? I was always under the impression a bottle blanket was the same thing as a bottle warmer. The kit includes a purge kit so i'm safe there. Folklore where can i find the two switches and the relay you were talking about? would the remote bottle opener, pressure limit control, pressure gauge come with the kit? and the kit does come with 50 and 75 shot jets.

How hard are those switches and relay to hook up?

thanxs Falkore... learned a lot in this thread...

I do think the tranny cooler is a good idea, I just don't include that as a part of the N2O system.  Definately get that as it is a cheap part for a lot of added safety.  If you understand relays and switches, the wiring is pretty straight forward.  The combo Window/WOT trigger can be bought pre-made. The blanket is just that, a blanket of insulation.  I'm pretty sure that the high limit pressure control is never included in a kit, but I could be wrong.  I'm sure that you could order whatever jets that you want for whatever shot that you want to spray.

..... And when did I become folk-lore?  I'm not that old you know!

Everytime i looked at your name and pic i just thought it was falklore til i looked close right now. Sorry.
Can i get an ebay tranny cooler or is there a specific brand people think is better?

and to be honest i don't really understand relays and switches. I'm gonna have to read up on that. if you have any good links that would be awesome but if not i'll do a little searching later on.

Switches are pretty simple, they cause a break in the circuit.  A relay isn't much more, but instead of your hand flipping the switch a control signal is used.  I did a writeup a week or 2 ago pertaining to a LED project that finch is working on, but I don't remember the name of the thread or exactly what info was included there.  I think I also posted links to other similar writeups.  I also drew an AutoCAD schematic for him, so if you PM him, I'm sure that he can send you a PDF or jpg of the drawing.  If you still need more info, you know where to find me!

Kevin:  Turbos and nitrous typically aren't the best of friends!  The turbine sees a ton of heat as is and with spray, you are increasing that tremendously!  If you definately want spray, I would use a 20 shot to help the spool from 2200 to 3600 only .... without running calculations to see where the upper limit should be, but with turbo, such a small shot wouldn't really be worth much at high rpms.  One device that I like for turbos is the interfreezer.  It doesn't add a huge amount of charge piping like an intercooler, but is way more effective at cooling the charge.  Only problem is that now you are carrying around a can of CO2.  I also like the tailpipe attachment to help spool and also the fire extinguisher attachment setup.  Some toys to look at!

EDIT:  I don't know what tranny cooler fits your car.  I had a 6th gen V6 and the one for that car is Hayden 403.  It all depends on what fits.  Find a good spot to mount it and measure how much space can be used ..... remember to allow for fittings and mounts.  The bigger, the better.  I don't see a problem with an ebay cheepie, but I'd use Hayden since they are a reputable company and also the part is pretty cheap .... like 40 bucks.

Yeah, I can't find that thread either. I do have the PDF and AutoCAD drawing if anybody wants it. Just PM me and I'll send it your way as quick as a bunny!

Wouldn't nitrous oxide cool the turbine rather than heat it? Last time I check N2O had a boiling point of -88.5ºC, seems like it would go from liquid to gas pretty quick while taking a ton of heat with it! Can you explain the tailpipe and fire extinguisher thing?

how can i tell what hayden tranny cooler to use. Each one i've come across just says universal...
where do most people mount the tranny cooler?

Can i use whichever cooler i have space for?
Falkore where'd you mount yours?

and when you say i need a nos pressure gauge are you talking about this:http://cgi.ebay.com/ebaymotors/Autometer-Phantom-Nitrous-Pressure-Gauge_W0QQcmdZViewItemQQcategoryZ46100QQihZ008QQitemZ180238061404QQrdZ1QQsspagenameZWDVW

Thanks falkore! and the oil cooler that fits our car is the same one that u have...
 
Edit: sorry, just noticed your sig lian... yours is a 93... ill check

You are thinking of the compressor which is in the intake path.  Typically, the N2O would be injected downstream of the compressor.  Upstream is usually just a filter or a small pipe to get cooler air.  Dry nitrous should be injected 12-18 inches upstream of the TB to get good mixing, but also so that when you let go of the gas, there isn't too much residual N2O in the intake line to cause leaning.  Dry can be injected as far upstream as the filter like the ZEX filter system, but the amount of charge in the pipework can cause the problems mentioned.  Wet nitrous should be kept as close to the valves as makes sense .... still downstream of the compressor.

The next point is that the boiling point changes with pressure.  I think you are looking at STP conditions, where the can is under tremendous pressure.

The turbine of the turbo sees the heat caused by the burnt N2O ..... and maybe also some that is still burning!

Tailpipe Thing

Interfreezer

The fire suppression link is down, but it is basically a soleniod that lets the CO2 into some hoses that are mounted under the hood with pressure control nozzles to CO2 fog under the hood to kill an engine fire since you already have this system piped all over the vehicle.

They are universal.  The car already has a tranny cooler and this one is to supplement that.  You want the biggest one that you can fit in cleanly.  A bigger coil = more heat transfer.  It needs to be mounted by the radiator so that it gets a lot of airflow when the car is moving.  Better airflow = more heat removal.

I never had one .... I didn't have N2O on my Accord.

That is a guage to mount in the cabin.  I meant a simple one that could mount on the can or under the hood.  It's purpose is to set up the heater controls to limit the pressure at the right point.  I never trust pre-engineered setpoints on controls.  IMO a manual needle in glass guage is more reliable.  What you posted is a good idea though, so you know if you have more spray or not.

Kevin .... I think that you weren't around so much when this happened, but I haven't had an Accord for 4 months already.  The tC is my current project.

does anyone know of a write up done on how to install a single fogger kit? or have a link? thx

wait up..... you no longer have your accord??!! what happened falkore

just noticed your sig... u know that when u ge the poly bushings your car is gonna feel super stiff man... Oh.... and I've bought a Mini Cooper (it was my g/f's and she couldn't pay for it and now im stock w/ it...it's very fun to drive though)

Falkore sold his before he had any issues with the 6th gen auto tranny, smart move me thinks.

yes... put it in front of the radiator.... where it gets cold air directly (that's kind of the point i guess)... get the biggest one you can!

Nope, I traded it in with the tranny basically dead.
