I hope you get it straightened out soon. A buddy and I are planning on a road trip mid-late summer to the DFW area. There's a good number of guys we talk to on the DTW board that run down there. Several are in the 12's and one just posted a best 12.24 1/4 - he's shooting for 11's on his next run. We're trailering mine down so I can turn the boost up and if I break something (which I'm sure I will 
) I can tow it home. LOL All I know is my transmission is NOT going to like 20+psi boost and nitrous LOL

I'm thinking of using the NX EFI on a pushbutton for a little extra if I need it (I'm coming for ya 1Slowz71 LOL) and the extra bottle and NOS purge for the spray bar and wiring on a boost pressure switch to come on a a certain boost level.
Here's the kicker- we are putting my intercooler in my hood scoop (sorta WRX style) but I'm using a pretty big ic. We're going to "box" and insulate the ic so heat soak won't be an issue and plan to angle the ic to be IN the scoop. I think it'll look badass when you look into the scoop and you see an intercooler, nitrous spray bar, maybe a solenoid if I can secure it and all. I just want it to be very functional so I can get the most benefit. I'll post a pic of the hood and the motor mock up as it is on the stand now. (BTW the forged crank came in today so now the fun begins
)
Any and ALL suggestions and ideas welcome.
Thanks

Hook the system to a pressure or temp switch so you do not waste the cooling media.
2nd. water injection maybe.

Thanks for the help Ricky.
Thsi is sorta new to me so if you could please explain the
I think you are saying to make sure the intercooler is completely boxed so that if using nitrous as a chiller it doesn't get to the comopressor on the turbo, right? And just curious, what will happen?
The ic is a 24x12x3 - does the spray bar need to surround the entire ic or just one section? I see the off the shelf spray bars are sorta oval and usually only cover less than half of the ic.
Thanks for your help
I have a snow performance meth injection kit installed too.

Make sure your incoming air to the intercooler can not get to the air inlet of the compressor.

I never understood why you would want to waste N02 on a spray bar setup just to cool the air a few degrees more. Why not just put a small shot right into the motor and get the same cooling affect (probably more), more power then just cooler air and a much more efficient use of the N02. Even using C02 with the spray bar (which is a lot cheaper then N02 and the same affect), I don't think you would gain that much with a few degrees cooler air.

I have always thought of the spray bars for the really high end, high boost race cars that are trying to get every little bit they can out of it. Kinda pricy over the long run IMO. You can only get a real good advantage out of it if you tune for the cooler temps. Do you want to have it tuned for the cooler temps and then run out and want to step on it when you are out of nitrous? Or get cocky and have confidence that it isn't going to knock without it? But if you change your tune from DD to strip when need be then that would be different.

I don't see how you can be sure that air is always coming in through the hood scoop at all road speeds, unless you have electric fan(s) on the IC. Or do you mean by boxing and insulating, that there will be two openings on the scoop, neither one going into the engine compartment?

Thanks for the responses.
First thing is I have 2 nitrous kits and I want to use both of them. I will have a small shot on the motor along with the turbo and the meth injection. I'm really only wanting to use the second kit on the intercooler because I have it and it's doing me no good in the garage and I get nitrous very cheap. That said, I want to do it right.
The scoop will not be open to the engine compartment. It will be boxed in and insulated. I have meth injection and would like my second nitrous kit on the intercooler and have the air through the scoops. I am able to tune on the fly so if I need to change for temp I can. I just want all I can get out of it for the few times I run it that hard. I will be on low boost (13pounds) 90% of the time.
This is what I'm asking for guys. Thanks for all of your input.

With a IC that big it would probably take at least a couple spray bars or you might could modify a Fuel Rail off something small maybe a 4-banger or V-6?!! And you could mount it at the base of the scoop and point it up so the imcoming air pushes it into the IC. Possibly like my very shitty paint rendering.
