Mine is about four inches away. I hear that the closer it is, the harder the nitrous will hit. Is this true? I have been on an unmonitored 70 shot that does not hit so hard. It feels more like VTEC. Now, if I mount it closer to the TB, will it hit harder? Is there any danger or setbacks to my car if I do this?

 

Talk to Thomas....Sx7r. He used to run his w/the nozzle like 1 inch away. Quote: "It hits hard."

Unmonitored?

I hope you have at least checked your plugs a few times. You have a 2k....not sure what the stock pump will handle.

Oops! Maybe I should have mentioned that I have an upgraded fuel pump and an MSD RPM activated window switch. I have not gotten the colder plugs. I did read that it hits a lot harder when it is close to the TB. I am just wondering what the setbacks are if my NOS kit recommends it to be 4 in. away.
Plus I am wondering how much of an exaggeration people are giving when they say it hits so much harder. None of my mods made my car "so much faster"

 

Hitting harder only means it will react a fraction of a second quicker. You are still putting in the same amount of nitrous and fuel so you won't get any more HP or anything magic.

I have tried putting the nozzle in 3 or 4 different spots but never really noticed any change.

 

When I had a dry setup, I tapped mine into the TB itself.

Don't know if it made a difference or not personally, since that's the only place I had it since the beg.

I do know that the car was quicker than some with the same shot/setup but theirs had the nozzle mounted further away. Can't say for sure that's the reason though. Take it with a grain of salt.

 

Okay I know HP numbers won't be different. I am looking for a more explosive pull when it first goes into my engine. Like the fast and furious, I want my Maxima to peel out at 100 mph. I heard that the closer it is to the TB, the harder it hits. Mine feels like VTEC.

 

I really hope your being sarcastic, cause you will NEVER be able to do the things F&F bs'd about.

A properly tuned 70 shot will be pretty "explosive" in it's own right. There are quite a few reasons why you don't feel yours as hard as it should. You're initial post leads me to believe that you installed your system and that's about it. Do you have a pressure gauge on the bottle? Bottle heater? Fuel Pressure gauge? EGT gauge?

If you just installed your system and have not tuned it, it is very possible and likely that you're realistically getting a 40-50 shot if not less. Nitrous is heavily dependent on tuning, bottle pressure, and fuel pressure to name a key few.

You really are playing with fire if you just install nitrous and leave it unchecked, not to mention you will NEVER reach it's full potential either.

 

Okay, yes I was kidding about the Fast And Furious thing. I have no gauges, bottle heaters or anything. I probably am getting only a 30 or 40 shot. All I am wondering is

1.Will the nitrous hit harder if the nozzle is mounted closer to the TB?
2. Is there any negatives about mounting it closer?
If it does, and there aren't really any negatives, I will mount it closer. If not, I won't bother with it since it isn't worth it.
Thanks guys.

 

Jaime is right if you don't have a heater, gauges etc you are really runnng blind and your chances of engine failure are greatly increased.

IF you already have the nozzle installed I wouldn't move it, if not put it as close as you can it won't hurt anything.

If you want it to hit hard get it set up properly and ensure you have the proper fuel pressure, bottle pressure etc.

My nozzle is about 4" from the throttle body and with a 100 shot in 2nd gear at 4000 RPM at 50 MPH with the throttle wide open and then hitting the nitrous switch the tires squeal. Is that what you are looking for?

 

The nitrous will "hit" harder the closer it is to the TB, that's a given since it will not have to travel as far. To be honest though, you are really going about it backwards. You should tune your system first, before trying to squeeze out a little more by changing mounting positions. You should really invest in a bottle heater, pressure gauge (either in-car or bottle mounted), and EGT gauge. You will be able to more accurately dial-in your system to perform at it's optimum for your application that way.

As Jime said, your car will react to nitrous differently but it's not out of the question for the car to pull like a scalded dog when you engage it. You have to tune it first. It's impossible to tune it w/o the things I mentioned above.

Just to give you an example: I dyno'd substantially lower JUST because my bottle pressure was at 700psi as opposed to the normal 900-1000psi. Bottle pressure is critical to tuning and getting the most out of your system. With a 70 shot, I was able to hit 13's in my 95 GLE auto consistently. When everything was up to snuff, I could easily take on the likes of 5.0's, TL's, most v-8's, etc...with just a decently tuned 70 shot.
