What's up guys? I need your help.

I have a 2007 Chevy Silverado NNBS that currently has an NX Spray bar system.

It only has a 5 lb bottle mounted underneath the passenger side rear seat. (crew cab) Which is fine because I only plan to run around a 25 shot. The reason for this is more the cooling effects to prevent rotor expansion in the supercharger instead under sustained periods of WOT. Additional horsepower really isn't necessary.

It currently runs at 21 pounds of boost and will see up to 24 in Houston at TX2K13, and it's doing that along with a Snow Stage III, twin 625mL Meth Injection system. Meth helped a ton but this will be even better, as the spray bar isn't doing as much as I had hoped.

With all that BS aside, I really just need to know what I should purchase to make this happen. And also I need input on button locations and what I should use to make the system spray only after 4,000rpm.

The truck is equipped with a transbrake and 2-step, and it leaves the line in four wheel drive, WOT, at 3,000RPM, and around 17 pounds of boost. Full boost comes in right as soon as you let go of the transbrake button and converter flashes to about 4,700. The problem is, alot of space around the drivers console is used up due to arming switch(s), transbrake button, meth controller, etc. Also, the little cubby in the 2WD versions is out because the **** is there for the transfer case. Pics would be great of ideas.

Let me know what else I need to post up to make this easier to make work.

Thank you.

 

why not do it in the center console itself. ltz or lt style interior?

 

LTZ. Do you know of a certain button assembly/setup for that?

 

not a readily available one {gto, fbody style}

that whole center section pops out, you could build one to fill that, and possibly move the cup holders to the passenger side of the console. or build something that would fit in the giant armrest/console itself. or take that little coin holder thing by the hvac and turn it into a switch panel with some low profile switches.

 

Hmmmm. Now that I look at it, all I need is a purge button. I wonder if I can place that somewhere cool like in the drivers side A/C vent in the wood grain like I did the opposing side.

The rest will be handled electronically with some sort of nitrous window over WOT switch. Since I tune it real rich on the boost, around 10.8 AFR with meth I expect low 11's on the nitrous without the need to pull timing. So that means it'll still run fine without changing the tune. If not, I'm going to do like you said and make a small switch bracket by the HVAC controls.

I would just put a nozzle about 4-6" before your throttle body in the intercooler piping. PM me your email and I can give you a wiring diagram as well with what wires to tap into to make a window switch and tps switch work. Therefore you can make the nitrous come on whenever you want. I have pics as well if you need some ideas.

 

that would be for the lt series dash. ltz doesn't have an opening that size in it

Something you might be interested in is a window switch. Have the window switch to start spraying at 4000 rpm and now worry about buttons. Just an idea
