Remember what a turbocharged car was like thirty years ago? You started off slow as the engine worked it’s way through the lag and when the boost came on, you had better know how to drive, ’cause you were getting all of the fun all at once. In a car like a Dodge Colt or Hyundai S’Coupe, that just meant that you went from “this sucks” to “Ok, that’s more like it!” in short order, but in a car like the Ferrari 288 GTO or a Porsche with the whale-tail spoiler, it meant that some very serious shit was about to go down and if you didn’t have your game tight, the hospital was suddenly on a list of destinations. Ask around about the Porsche’s “Widowmaker” reputation sometime!
The same can be said for nitrous. It doesn’t take much to go from “whoa!” to “WHOAAAAA…!!!” with the push of a button if you’re just sending all of it at once into the engine. That’s why progressive nitrous systems are a good idea: instead of going from zero to “party naked” at the launch, you can start off with just a little then kick in the rest of the fun when the weight transfer has settled down and you’re moving quickly enough that traction isn’t that much of an issue anymore. Or, you can do like the driver of this G-body Regal did and just send it all in one shot!
There’s a 240Z locally here (NorCal) that has a full chassis set-up (8.50 cert.) (408 LS,5-speed) that uses a 400hp NOS hit on the line, no complete passes yet but the wheelies in 1st and 2nd gear are impressive (actually looks crazy) and he’s having fun. It’s a street car, he used it in his wedding (new wife insisted, she’s a keeper).
