I've seen this question asked before, but haven't seen a response to it.

If you are at WOT, can you flip the activation switch to spray? Is it safe, how will the car react?
Is it better to Activate, and then go into WOT?

Thanks in advance for clearing this up.

 

Yes its safe, makes no difference. A switch is a switch whether its WOT or manual.

Just don't defeat the WOT switch so you could possibly spray when not at WOT.

The higher you do it in the RPM band the less effect you will feel because the percentage of power increase you get is less than when lower in the band because nitrous always puts out the same HP increase, no matter where it is activated.

 

Ahh I see, thanks for the info. I guess this is where my RPM Window Switch comes in.

Would you think it's most effective to set around 3k and end around 6k?
