Just like the question.. not so much how does the injection create the power but when installing say a Zex Wet Kit.. you just flip the switch when you are at WOT?? or can you flip the switch sitting at idle and it will kick when you hit WoT??

 

try using the search feature we have on the forum

this has been covered many of times how NOS works

 

You turn the power on on the system. Then you can go WOT and it will start spraying, but it will not spray under 3000rpm or like 20mph because under 3000rpm it will detonate and under 20 to 25mph'ish you will get no traction.
