You can use your system from approx. 3000 rpms up in first gear through the end of a 1/4 mile dragway. I run a 125 hp shot on my NX wet system once I hit 2800 (every car is different) in first gear, and shut it off once I hit the 1/4 mile mark, ussually in around 13.6 seconds. I wouldn't want to spray into 4th gear, as it probably isn't that good on the overdrive band....lol
