So, its safe if done right but unless you're a pro drag racer you're a Dumb idiot ? Why is that ? What if you want less lag - does that make you a dumb idiot ?
My understanding of nitrous is as long as revs are in the midrange, throttle is wide open and CAR IS TUNED PROPERLY you won't have a problem.
I'm busy with GTX35 then I'll consider nitrous.
Do it raggedoutsti - Im looking forward to seeing the results.

Say I am running something a lot bigger then a 35r.....40+ something, this is a application where nitrous can help. Say i am running a new GTX30R or below......don't bother using nitrous.....you just can't shift that fast sorry. Maybe with a dogbox.

Also you aren't going to get the true potential using nitrous +93pump. Just run Meth if this is your plan.

Let me give you a break down of Nitrous users ....
Dumb idiots and Professional drag users....there is no middle ground, No gray area. So please tell me which are you?

You want Nitrous ....spend big, buy a stand alone if you can afford it. READ ALOT!!

ok, just doing a lot of wondering , getting around 300 wheel is relatively cheap, but if i want a streetable 300hp car and I want more on the drag strip I dont see why it is such a terrible idea. I have seen alot of cars with huge turbos spraying to get rid of lag but what if you do the opposite and want to move your peak power up by nitrous to get a better quarter mile time while you have a fast spooling small turbo already. there is a lot to take into consideration but if you run a ewg and can bypass the turbo with all the exhaust from the nitrous it should work.

Nitrous can and does work with a turbo, in fact the cooling effect from nitrous (a gas that rapidly expands has a super cooling effect) helps with air temps entering your engine. Keep in mind my experience comes from a V8. The problem your going to run into is the extreme increase in cylinder temps, your rings and pistons are going to take alot of abuse and need to be strong enough to handle this. Staged kits are great for easing into power also, rather than making 150% power in one go you can step the power increase much like a rolling start is less damaging than dropping a clutch at 6500 rpm and catching traction. Window switches will ensure you dont rapidly exceed red line and can be set for WOT use only, allowing you to leave the bottle on and drive normally. Now as far as wet and dry kits, dry nitrous is garbage (my opinion), you should always add fuel to supplement the increase in air (nitrous combustion produces nitrogen and oxygen gas), this is where many people go wrong. A dry kit is cheap but your car has to be tuned to always add fuel as if the car is always on spray, whereas a wet kit will add fuel at the same time as gas, all you have to worry about is timing. Which brings me to my last point, a good nitrous tune decreases overall ignition timing so you have less power most of the time but allows you to take advantage of more power when you are using nitrous, its a trade off. The reason people with street driven turbo cars don't normally use nitrous? They can push a lot of power with a good turbo with no need to spent a lot of money to add another system that they don,t need.

We are running just 35bhp shot of the WET NOS on our wagon,which is controlled via Syvecs S6 ECU and we are using this only for spool up on drag strip on 1 off the 8 maps,in our case NOS working when is boost in positive(from 0bar) and must admit working nicely

its more cost effective to setup an external water spray kit or co2 kit if you want to bring your intercooler temps down.

There are plenty of people succesfully running Nitrous on Subarus.

THE biggest complaints that Nitrous isn't reliable or safe is due to the fact that most people use WET nitrous setups. The problems that are often seen is that the nozzles for NOx and Fuel are quite far away from the intake valves... If single Nozzles for NOx/Fuel are used it is often placed close to the Throttle body.

Due to this the whole intake plenum is filled with NOx/Fuel mixture which is highly flammable and this creates the dangers. When you run into the revlimiter or engage the Nitrous too early it can backfire and you'll split the whole intake manifold

We have run Nitrous on many different types of cars and always go for a DRY nitrous system with a proper Standalone that controls EVERYTHING. If you use a Multi-Nozzle Direct Port setup very close to the intake valves there is no dangerous explosive mixture in the Intake plenum and it's quite safe. Additional Fuel is coming from the Normal Injectors so they need to have enough headroom and the ECU will check whether all conditions are met and operates the nitrous.

A proper nitrous setup is safe and reliable BUT it isn't cheap. A Cheap nitrous setup usually ends in tears.

Cheers,

Jasper.

Apparently your tuner has a different methodology on how to tune nitrous on a subaru. Most nitrous kits for turboed cars in the market are wet kits. There should be no fuel puddling if the proper sized fuel jet is used.
There is no additional fuel coming from the injectors since they are at a fixed volume. Spraying a dry kit before the maf does not trick the ecu to add more fuel either. Perhaps your tuner sets the map rich at the rpm ranges when nitrous is used. I'm not saying he's wrong or right, maybe dry kits are his preference.

A wet kit has been used on my motor for years up to a 100 shot with no ill effects other than my wallet being hit at bottle fill ups.

^^^^ You must have totally misunderstood what I said

I use DRY nitrous kits because it is safer as the EXTRA fuel you need when you start spraying nitrous comes from the Normal Fuel injectors (1 per Cylinder or 2 if I run a staged setup ) which is controlled from a PROPER motorsports ECU which is a standalone.

I never said anything about Fuel puddling. I mentioned the dangers from a WET kit being that the N2O AND Fuel are coming from seperate solenoids which control nozzles which are often FAR away from the Inlet valves. The volume that sits in between the nozzles and the intake valves is filled with a homogenous N2O/Fuel mixture since the Fuel was added from the WET kit remember.......... This is what gives the explosive mixture present in the Intake manifold. When there is just as much as one backfire....... LOL.

I never mentioned running a MAF.... OE cars runs MAF sensors..... anything proper out there runs SD.

The ECUs I use have 3D maps for progressive N2O solenoids if you wish the control the amount of N2O and at the same time there are Fuel maps that come into action when N2O is spraying so NO I'm not tuning the maps rich where nitrous is used. Everything is controlled in a proper way.

i know what you said, but i have a different opinion of wet systems than you do from my own experience with wet kits.
Lets agree to disagree
As you said, there are plenty of people that have successfully run nitrous on a subaru.

We are running WET nitrous and working very well,just our solenoids are controlled as per Jasper via ECU(probably our best investment)

Still we are running only 35bhp jet,which is OK for spool up(when boost reach positive boost),but on the new 2.35L we will be using 75bhp and DRY nitrous like for spool up and top end

Stay away from nitrous you don't want nitrogen or oxygen in your engine at all.. .

Nitrous is only dangerous if your a hs dropout.

turbos put nitrogen and oxygen at greater pressure into your engine as well for those that didn't get basic chemesty.

Wow I can't believe what im reading.. Have u done any research? Its one of the most widely used power adders in the world & has been proven in more forms of racing than meth ever will. I've run 35hp-350hp shots of nitrous on subarus with issues & yes I've lost a motor to it but that's part of building cars.. Please don't forget that nitrous is a known power adder & meth is a known as a cure to a improperly sized turbo..

I disagree with that statement. Meth is known as octane booster, same as using race gas or E85. Meth allows you to run more timing, now some do use it for cooling effect and run higher boost with it but main benefit is resistance to knock.

Sure u did & keep tellin your self how great meth.. Cause the proof says its out dated crap & sooner or later you will finally see what meth is.. I sure don't see anyone
build a monster & add a meth kit unless it was built by a someone that has no idea how to size a turbo..

I don't see too many build a "monster" and add nitrous either. Either one is a bandaid. And again, the same can be said about someone who has no idea how to size a turbo. I do think that no idea how to size an IC or injectors would be more fitting for meth though. I would never tell myself that meth is "great" I know what it is, and why I have used it in the past. If you would like the breakdown I can give it to you.

It started as such a good post than just went south.. I wish the haters would just stay in their own posts/forums & not talk crap in everyone else's.. You sure don't see the nos guys goin into a meth post or the turbo guys talkin crap in the na forums but I guess its true meth makes you dumb if you keep using it..

I don't plan on nitrous, atleast not for a long time. But a myth I've always heard about it is that it eats away normal lines? Meaning (i think) you have to replace everyline from tank to injectors? True or false?

I believe you are thinking of E85. Nitrous is self contained kit and doesn't go through your fuel tank or injectors.
