Uh oh its getting wavy in here!

 

Raise your hand if you think it's cool to tell people you run nitrous on the street!

That should make it easy to pick out the 16 years olds and morons...(not a flame to 16 year-olds).

 

i've always found it best to pass gas "quietly", as to not disturb, the pulley only "don't stink" crowd. sometimes they take offense to our "clear the room" hp advantage, as well as the "eggy" aftermath.

 

Puts the "plus" in Nitrous-plus. I'm still suprised they don't charge extra for it, or something....

 

I post something to help the guy out and it gets turned around.
1. if you post kill stories here with nitrous you will be ridiculed.
2. if you post kill stories here with pullies there is a chance you will be ridiculed.

Keeping more in line with the topic. I am pretty sure if you run nitrous it must be physically disconnected when driving upon public roads. That can be a pain unless you want to break the law(which I would never encourage). With the pullies you can run on the street, but anytime you step on the gas you could be in violation of the law. ie. public display of speed or accelerating too fast. Yes, these are offenses which can get you a citation.

 

So, the "run nitrous at the track only" kinda makes sense then?
I never disconnect mine. I just keep the bottle closed.

I'm not really wanting to get up on the soap box again, really.
But, the story the other day about doing 130+ hitting the juice on a road that we all drive on here in the TampaBay area really hit a nerve with me. My wife and family drive on that bridge.

It was in the middle of the day and weaving in an out of traffic. You won't get an apology for flaming from anybody on that one, especially me...

Pullies vs nitrous isn't the issue. Sense and common sense is the issue, IMO.

That's just my .02

 

those are local laws. no federal law concerning nitrous ingestion in vehicles

 

RTKILLA - Not a flame, justwant to share some knowledge.


I wonder how many people think this is the way nitrous works?
I'm not a nitrous guy but we played with it some in the 70's. One of the first performance uses was on high speed english bombers in WW II, Lancaster's or Mosquito's i think.

Laughing gas basically allows you to put a bigger charge of fuel into the cylinder duing the intake stroke. More fuel results in a couple of things. First you got more fuel mixture in the compression stroke so you get more power when you ignite it for the power stroke. There's a chemistry thing and a physical cooling thing that nitrous creates when it is added to a motor. Boost is strictly a mechanical function where you are forcing more air and fuel through a system. Nitrous doesn't do that.

I'll have to get out some old references but I think I am basically right so lets not screw others up with misinformation.

RTKILLA - No flame at all; I think there is alot of misunderstanding out there.

Perhaps I'm wrong and I will hear about it I'm sure.

 

Actually, you're both correct.

If you look at the boost gauge during "the moment", it jumps up significantly.

It may just be the pressure of the incoming N20?

Anybody want to give us another explanation?

 

I feel there's nothing wrong with running NO2 & a blower with different pullies. I just look at it this way. The blower is 1 power adder and the NO2 is another power adder if you choose to run both then you have 2 power adders...So when i'm racing someone i take that into consideration 1 power adder against 2 poweradders. So i feel if you want to compare apples to apples then either run NO2 Only. and remove your Blower. or run just the blower with no NO2. Then we will have a fair comparison.I believe this is how most races are set up. blower or NO2.Not Both. Now if we want the most power we can get. then run Both....JL

 

*sigh* I read that whole think hoping for a real answer from the infamous JL.

The tangent we're on now is the purpose of the extra power. Street or strip? That and "should you run nitrous on the street".

So, both tuners say run more boost and nitrous. Hmmmm?

 

Tampa: and what would that be?

 

Why does the boost gauge jump when you hit the button?

Somebody says nitrous increases boost, somebody says it doesn't. Some might say it's the pressure being introduced.

With all due respect, you have a greater body of knowledge to draw from. We'd believe the answer from you.

Oh, and how do you feel about running nitrous on city streets?

 

Guys please, let's not turn this thread into a "nitrous used on the street" war, or a "nitrous vs no nitrous war". This post started out informative, let's keep it that way so it doesn't get locked.

 

Here's my take on nitrous increasing boost....

Nitrous increases cylinder pressure, just like boost does. So technically, nitrous does increase boost. However, you don't measure boost in the combustion chamber, you measure it in the intake, so you are not going to see that pressure increase on your gauge.

Now some people see thier boost gauge jump a tad when they hit the nitrous. I would think that increase is from the nitrous cooling the incoming air, so now you have colder air being measured by the gauge. Just like when you drive your truck when it's 50 degrees out and you see more boost.

That's my take on it. Not sure it's 100% right, but logically makes sense to me.
