Best Way to Activate NOS???

[Bayou Busa]

What the best way to activate the nitrous?  While running the 1/4, it's really tough watching rpm and shifting on time.  It appears that it would be very difficult to add another operation like pressing the horn or starter button.  I plan to get a dry 40 shot of NOS and saw  an activation switch on a NX wet system that activated the NOS by opening the throttle 100%...

Can the throttle activation switch be installed with the dry shot system   If so, where can that switch be purchased

you need a switch like this http://store.summitracing.com/ .  anyone selling nitrous kits should be able to get you one.  only problem is once you arm system it will come on at full throttle.  better be ready for that first gear hit   .

What method do you use? How difficult is it at the track?

or any switch like that a piece of aluminum and some time
I like hitting the button and second gear is too late
that way if I need to I can lift just the spray ,so the bike does not SLAM down if I wheely
Just Wot switch would scare me.
If I was to redesign my current system
  I would use a rpm window switch to turn it on and off based on rpm
(now the rpm switch just turns it off,So I could misakenly hit it at too low a rpm)
so I would have a right thumb pushbutton(left is airshift)
rpm switch
Hobbs switch
Wot switch
  Some people tell me I don't need the rpm switch to turn it off at 10,400
but it can't hurt right?
sorry for the long post but I was bored

what's the deal with your E.T.'s you only gained one tenth with spray

Thanks guys....

One last question...How is the line purged prior to activation?

[Nosgsx1300]

what's the deal with your E.T.'s you only gained one tenth with spray

the difference is a 1.52 short on motor
and a 1.701 on spray
plus my clutch was slipping bad on the gas, and I only spray after I get eliminated from bracket racing ,So I have not sprayed that much this year

If you will use a DPDT switch, you can use your starter button as your N2O button and turn on your pump and solenoids at the same time.  If you race at a sanctioned event, make sure you wire your pump circuit so that it shuts off when the Kill lanyard is pulled.  ECTA, Prostar, SCTA, AHDRA, they're all the same on this rule.  A WOT is bad juju.  A forceful wheelie can allow your hand to pull on the throttle when it comes down and force your WOT to bump again.  Bad juju.  Your spray should always be a manual activation of some sort.  WOT is good as an additional part of the circuit along with a activation button if thats how you want it to come on.  But a manual switch/button is always perferred as the primary activator.

I use my Starter button for my N2O and my horn button as my shifter button.  Both on switches to revert back to normal mode.

Good advice Guy.
