Ok I've never had nitrous on anything. I've never driven or rode in a car with nitrous so I can't say I know what it feels like or how great it is. However, I have seen Gone in 60 Seconds on DVD like 10 million times and every time Nicholas Cage hits the "Go Baby Go" button and Eleanor takes off to 160, I gotta admit it makes me wonder too...
Personally though, I wouldn't put nitrous on a 4.0L. Not if you plan on keeping it for very long. There's just no way in hell that a 4.0L can stand up to it and have a long life. I'm not saying if you run nitrous your motors gonna explode. Course not. I just have never though 4.0Ls were that great.
A 5.0L would be friggin awesome with nitrous. I have a 5.0L, and yes in a way nitrous is an excellent alternative to supercharging when it comes to adding power for the price. But obviously unless you got a really, really, REALLY big nitrous bottle you're not gonna have that extra power for more than a few seconds. Plus I'm not sure what it costs to have the bottle refilled every time, so that may get expensive. I know one thing for sure, if I had nitrous I'd certainly use it, so I'd definitely be getting my bottle(s) refilled quite often.
A question for anyone who's actually had nitrous on a 5.0L....
Do you think its possible, if you sprayed the nitrous early enough to do an all-wheel drive burnout?
Man that would be great. I'd need a new set of tires every week, but oh well. I'd talk to Pep Boys and see if they could cut me a deal on a lifetime supply of Futura tires. They'd probably only charge me like $100 for a lifetime supply. Those tires obviously suck.
