SlayerwithaFC3S

this guy i recently talked to sweared up and down his car ran 12's comeplety stock with a FC i new thats pretty much impossible unless his car weighed half as much or something but he also said he ran it at 15 psi before he blew the engine i donno much about turbo's but doesnt fuel cut happen at about 8 psi or something which would make it immposible to get up to 15 i donno someone slap me if i am making myself sound like a idiot lol but is there info around here on turbo's or on the net any good links or posts?

sure you could run 15psi and probably run 12's 100% stock. the problem as he found is it probably blew pretty dam fast...

SlayerwithaFC3S

but what about the fuel cutters? i mean dont they prevent such high boost levels from occuring

MazdaRx7Racer4Life

theres a fuel cut defensor, a littlwe chip that you ut in your t2 to make sre that it doesn' get fuel cut, you can rn an infinite (exagerratin) amount of bost on the sock turbo and engine.................the question is how much (seconds) will it last?

SlayerwithaFC3S

lol i dont think he got that chip because he bought it a month before it blew now he tells me JDM engine which i dont care for because there almost the same usdm and jdm i just told him get the jdm because by the time its dropped in ill be running nitrous and ill whoop his ***

hehe, forced induction, wether nitrous, or turbo, is th way to go. Just know what your dong, you want something that ill last you more than two days

N2O isnt really forced induction.

very nice! I think that it's about time that people started thinking about us poor N/A guy's. I am really intrested in purchasing a nos kit for my car. I think that is one of the only ways to really make power for us. at least with nos we can finally keep up with own blown counterparts!

Unfortunately... This won't be for you poor N/A guys. Adding nitrous is a form of forced induction, so you won't be N/A anymore.

I have a couple other idea's as well, but I don't need as much feed back on them. I'll keep you guys posted.

Don't worry... I still love N/A's, even though I am now boosted.

I run 15# on my stock turbo and get 265rwhp. Too many naysayers and dumbasses say I'm not really doing this despite dyno runs and personal accounts from other forum members. The others say my car is a grenade. Two seasons of autocross, lapping days, and daily driving say otherwise. But any engine sees a helluva lot more pressure that 15# everytime there's a combustion so that's not the weak point. Uncontrolled combustion is the killer of apex seals. That's bad tuning. The weak point is the turbo. I am maxing out the stock turbo and there is no way I am close to 12's. I'm surprised that it has yet to start puking oil at 15# after all this time. I'd have to have the right suspension for drag, a serious Jenny Craig diet on my car, and the drivetrain and slicks to put the power down to see 12's. But it would be a track only car at that point.

I have to say that guy, even if he swears up and down (liars tend to do that anyways) that he is doing 12's with that setup that he has let you believe that he runs as, is a big fat liar. A liar, liar, liar. Pants on fire.

Nitrous is forced induction, forcing more oxygen into the engine

Jerk_Racer

Or at least it's referred to as a power adder.

Its a power adder, but its also forced induction

'forcing' more oxygen into the engine? how does this work? It's more like increasing air density to allow more oxygen into the engine, as well as producing oxygen when it burns, but it's really not 'forcing' anything But *shrug* depends on your definition of 'forced'

FCdemon

nitrous is most definately NOT forced induction.. unless there is a pump of some kind, it is not forcing anything.

Ryde _Or_Die

Nitrous is known commonly as a form of Forced Induction.

Oh and about the guy running 12s with the stock engine and turbo, I believe there was a thread a while back that had someone else that had done it too.

Nitrous is not 'forced' induction. If it was forced in there, it would 'force' all the other air out the open end of the airbox. There's nothing to keep any pressure inside the NA intake...whatsoever. Turbos pressurize everything behind them, thus forcing air into the motor. With nitrous, even if it did incrementally raise the pressure in the mani. for a bit, it would just end up letting less air in at the airbox end.

why does it matter? As long as the car goes faster, the owner should be happy. But just for those of you that have to know, nitrous is not forced induction. Forced induction would need some mechanism to "force" air or mixture into the engine. Nitrous does not do that. If it is anything, it should be called a 'fuel economy modifier' or a 'power adder' but not forced induction.

When force is applied to something tangible, ie the insides of a manifold, and the manifold does not accelerate (applied force in the opposite direction) what you have is a pressure increase on the area...

So like Manolis D has noted, if there isn't a sustained pressure build, there is no sustained force...

For more details, please read pages 1 and 2 of any physics book.

V8what?!

That's funny...I thought this guy was asking about 15 psi on a stock turbo, and not the definition of forced induction...oh well, my bad.

Anyone who thinks N2O forces more oxygen into a combustion chamber is an idiot and has NO idea of how a nitrous system works.

adamlewis

Thank you, thank you, thank you.


Its so good to see that some people on here actually know their stuff.
