Don't use as rich of a fuel pill, and use a cheap time-based progressive controller, and bump it to 125hp =)

Set it to 50% at 0 sec, 100% at 1 sec. One, it won't go 'as' lean at that spike, and two, when it does spike, it will be spraying only half the amount of n2o/fuel, making it less likely to do any damage over the long term.

Also, pulsing your solenoids for 1 second at a time isn't going to hurt them at all. It's the guys that use the RPM based controllers and pulse them nearly the entire time that they are spraying that wear em out quick.

 

Me, too, and I'm so close. I haven't been back out with my current clutch, but I know it's possible. Good luck.
I don't think you should be worried about dyno output numbers, especially whp. You should be worried about how much torque you're making just to hit that 400 horses.
People can say that, but my Z's not getting more than 100 whp shot without a proper tune. I still worry when I spray my 100.
That's a huge nitrous jet! No wonder you're trapping 115.
Just curious, where is your fogger located?

 

What do you guys normally tune the A/F for when you spray? I've heard 12.0-12.5 with proper tuning is the range. Enlighten me please.

 

^11:5-11:7. Mild timing as well. Safe is good. Timing is far more important with giggle gas than fatness of the tune...............though it will just as easily go boom if you lean it out without diligence.

 

11's sound good in my auto. Thinking about going for it also. Cant help myself.

 

I would shoot for mid to upper 11s when on the juice. Mine ends up around 11.8:1 toward the end of the rev range. I don't have a tune, though, so I do experience lean spike.
