It does unless you flip the arm switch off. If you flip the arm switch off, it kills the nitrous as soon as it is off, but unless I'm missing something, I don't see any reason to be concerned about the nitrous stopping as you lift.So when you cross the finish line it cuts the nitrous as you lift the throttle?
I want the nitrous long gone before i lift.

What you have there is an old school manual switch, the way I like to spray.
When the system is armed and you push the button it will begin to spray, when you let off the button it will stop spraying.
I'd question using that big of a shot a lot on a stocker but once and a while at the track - wowOk guys, in the interest of sharing what I learned today, I thought I would let you all know how it went. I don't remember all the specifics on the tune, but if they weren't same as what I posted earlier, they were very similar. The only thing that might be different is a little less timing (I don't remember if I lowered it any or not).
Here's how the system was set up.
15 lb bottle with 1000 lbs of pressure (bottle heater was installed and in use)
-4 AN feed line from bottle to solenoid
.125 bottom outlet solenoid with flow through purge (with purge solenoid installed and used each pass)
18" -3 AN line from solenoid to nozzle (I didn't measure, but it seemed pretty close to 18")
Nozzle installed after CAC in aluminum tube pointed directly at the bridge neck
Set to spray at WOT with 25 PSI of boost (thinking about backing this down to 20 PSI)
Only one fuel only pass was made, but it did 13.00 @ 100 MPH
With a .062 jet, it did 12.34 @ 108 MPH
With a .078 jet, it did 12.09 @ 111 MPH
I had wondered about when the "auto" kits kicked outSo when you cross the finish line it cuts the nitrous as you lift the throttle?

Not sure what Dmitri did different on his low 10's and 9.9x but on some of his runs I seen in person it looked like the shot out of the hole shocked the tires, ect too much and he lost time there, JMO.All I know is there is a truck running mid 10s and over 1000 HP with a very similar setup (as far as how the nitrous is installed/wired). The only difference is his is a dual stage with two pressure switches, one set at 20 PSI and the other set at 40 PSI, and he hasn't had any problems with it for over 2 years. He was running a single stage kit for several years before that. I think that's good enough for me. I set this kit at 25 PSI so the truck could get a little further out of the hole before it started to spray, but I'm thinking of backing it down to 20 because you can feel the truck launch and then try to break the tires loose when the nitrous hits. I think the initial tire shock of the launch coupled with the nitrous might make it work better, but that's just a theory right now.
Happy button :spit:What you have there is an old school manual switch, the way I like to spray.

what about a wet kit throwing some fuel in with the nos.
Not needed on a diesel. Not only that, but I wouldn't do it.
