I was just curious, can nitrous be used at high speeds? Like on the highway? i always hear of people spraying on launches and stuff. But would it be safe to spray when your already going around 60mph +? or would that be a death wish for the motor? I ask because once you get up in the higher speeds, you're in a higher gear, which means lower RPM's and I have heard that you shouldnt spray like that.

 

Its generally safe to use at 4000+ RPM in 10 second intervals.

 

I wouldn't spray it while in low rpm at a higher gear. Begin your spray at about 3500 rpm in the proper gear.
