The ZEX dry kit comes with a TPS voltage sensor switch that allows the system to spray only at WOT. Certainly one of the safest systems out there. I've yet to see a blown plastic intake or air box due to this system contrary to some statements on here. Guess they are the experts! And yes, you can hit it off the line and no you don't need a window switch. I never have in 6 years.
Of course, no matter the upgrade, it is wise to change the fuel pump to ensure enough fuel to the motor. Tuning is important as well.
As far as Safe goes, don't pay any attention to some of these dumb arses, they don't have a clue about nitrous and talk out their asses.
I ran the system on a stock motor for 6 years and am still running it. You just have to be safe, not greedy and know what you are doing.
BUT THEN, thats the same on any power adder or they go boom. Right Justin H?? If you can't pass correct information then don't pass any!!
