Real cars with real power don't need automotive steroids and too much of that nitrous oxide (much over a 125 shot on stock pistons) will leave your Jeep on the side of the road with a fried engine.
That Mustang you mentioned beating would blow you away with the equivalent nitrous shot. Hope you don't meet him when your blue bottle is empty.
In my opinion, nitrous is for those too lazy to do the real planning and the hard work necessary to build a fast car or else it's for teenagers who saw The Fast and the Furious and thought it was based on reality, where every little four-cylinder grocery getter just needs a lot of stickers and 'Nawwwws' (NOS: for Nitrous Oxide Systems, major manufacturer of Nitrous Oxide set-ups) to 'run in the 10's'. In their dreams. Nitrous works but it's temporary, bad for the stock engine not built to take it and too easy.
Real men drive '70 Dodge Chargers with blown big blocks like Vin Diesel drove in The Fast and the Furious. That's a Man's car. No nitrous needed. End of story.
Real Men don't need NAWWWSSSS!
IN YOUR DREAMS!!!!! Nitrous like anything else is a tool to get the maximum performance and HP out of an engine. I bet you say the same thing about Supercharging too huh?
Nitrous is for lazy people? HA! You spec out an inline 6 and design a custom fogger kit for it. Upgrade your FI, intakes, custom valve work, yadda, yadda, yadda and see how far you get upping the horsepower on a stock 4.0 litre 190HP rated motor and see where you get.
Run into a putrid little "pony car" with my bottle empty? Been there, done that. Still beat 'em. I just like the looks on their faces when the pull up to the next light, and they know they got beat real bad!
Want a real car? I had one of these:
390 Cubic Inches of the baddest motor on the planet. It was called the Vette Killer for a reason - because it ate 454 big block Vettes for lunch! Boy, do I miss that car. Too bad I rolled it...
