Just juiced my car this past weekend. It went from a 11.38 at 121 mph to a 11.12 at 124 mph. A small 75 shot. Still have stock unported heads (upgraded valve springs) 25 lbs of boost without nitrous and my boost went to 27 lbs on the spray.
I launched with the juice and stayed with it all the way through the 1/4 mile. I could not believe how hard the car took off with the spray. It was awesome. I believe if I would of had some true slicks instead of the Hoosier quick pro times (cheater slicks) It probably would of ran a high 10.
Wouldn't you gain a few more mph from a 75 shot?? I watched I guy down here go from 11.2 @118 to 10.7 @125 on a small 75 shot. He was also spraying it the entire 1/4.
