Some lad said nitrous is a very complicated and hard set up and is a great part of racing.
bull****
say a 75hp shot of nitrous from say a Zex kit is ****ing childs play to anyone who knows a little about cars. It's not complicated, it's simple, and stupid.
I don't know about America, cause your rules are wacky, but in most of the world nitrous in a road car is illegal, so you have to hide it

, basically, the main point of nitrous in a turbo drag car is to eliminate lag.
I still don't want nitrous in any GT game, look at the name Gran Turismo, it has nothing to do with drag racing and should never in the future, but in PDs infinite wisdom they made the game so realistic and amazing you could drag down the 1/4 mile anyways, or set up for drift or whatever, brilliant, anyways, it's still gran turismo, if it were Drag Master 8000, then fine have nitrous, but it's not, drag racing is going to be a tiny, and pointless part of GT4, and one that i'll spend the least ammount of time on, really i don't care how fast i can tune a car to run in a video game down a straight line, i'd use it to test stock cars, that's what i do in GT3, and correct me if i'm wrong but no stock car has ran nitrous? *except one or two, can't remember*
anyways, what button do you want to go "blurry effects ohhh look at it, and speed boost nitrous", most nitrous set ups are through the efi system, and are activated by a manager whenever you've tuned it to, typically full throttle, so you could have that too, BUT the common idiot who plays racing games only knows two ways of pressing a accelerator button, on or off. So you're common lads going to be running nitrous through their system while their in neutral. Awesome, and no doubt so realistic.
Also, who's been talking about media hype, saying us people who don't like nitrous systems in GT4, (and me who doesn't like them in general) are just taken in by the media hype! that's ridiculous, what's the media all about in this scene? Nitrous is brilliant and it's "cool" makes your car go fast. Jeez, it's the other way around, you've been taken in by the hype, we see through it.
No i'm not some idiot who doesn't know what they're talking about, i know alot about nitrous systems and their useless application, that's why i don't like them, and don't want them, sure they're fun, especially in a 4wd GSR, but they're just stupid and impractical.
BUT
I have an idea that might just work.
You american chaps can have nitrous, and everywhere else can go without it.
