Thoughts on NOS.

[turbonutter69]

I was thinking bout performance upgrades earlier for my car an thought of NOS. But then thought i'd not heard anyone on here really comment about it. So come on who's ever had NOS in there car or have you got it now.
I've never had it myself but read loads of different reviews. Whats your thoughts on laughing gas? If I get some it will mean I'm stripping the car out for track day use next year so it wouldn't be for the road. But I do like the thought of doubling my BHP with the push of a button....lol

 

[claymore]

i use nos on all my cars, and you'll be pleased to know that my son has a 50hp shot on his almera gti. I think it's the cheapest hp upgrade you can do. what other mod can you do for less than £500 and gain more than 50hp? and once you'v bought the kit, it only costs about £6 to change the hp to anything you like, plus if you change the car you can take the kit off and put it on your new car.

Agree, with the caveat that there will be additional costs once you go much higher than 50bhp increase if you want to keep all of your engine parts under the bonnet

It's funny we all talk NOS when actually we all mean Nitrous. I'm surprise OG let you get away with that. It does seem to be one of the easiest power upgrades around.

How much are refills though? Are they easy to get refills for?

 

[The JAF]

this is one thing i find funny, people always say yeah ive got 250 bhp with a 50 bhp shot of nos, but its only when youve pressed the button, great for willy waving or drag racing, but utterly pointlesss on track or on the road.

 

[prevtec]

is nos not dangerous???

ive saw before on tv about street racers in the usa, and i racer died because the nos tank blew up

or is this a once off thing??
it must be cool doubling you hp with a switch

 

[turbonutter69]

Point taken Jaf mate but if I go the route of stripping my car for the track I'd have the NOS to come in automatically at a certain amount of revs so the button would be eliminated. It was only a thought for some quick cheap Horses....

Dont understand what you mean, I have mine set to fire at full throttle, I can get quite a few laps in with a full bottle,
I think Its one of the best upgrades, you only have the power when you want it. what's the point in having 250hp all the time when you cant really take advantage of it, I much prefere to have my 200hp for normal use then an extra 60hp when the conditions dictate ( ie the odd scoobe bashing)

@ waynne, It costs about £35 to £45 pounds to fill, depending on weather and how much pressure you get into the bottle.

 

[Wcnwzrd]

i had nitrous in my vette, but not anything else. the 50hp shot wouldn't do much for most people running high end hp just due to the amount of hp it takes to go up in speed after a certain point and anything higher, you will be spending way more than the kit cost if you want to be able to use your engine afterwards. main thing to remember, make sure your bottle isn't somewhere it will heat up, the racer that had his tank blow on him was probably storing it in the window or some place like that. a full bottle in a window of a car on a 90+ day is just asking for trouble.

The traditional way of activating N2O systems is with a switch on the throttle, set to operate the sytem only on full throttle. You want to be able to use nitrous at lowest possible RPM (usually around 3000rpm) as it delivers extra power instantly, greatly increasing torque at low revs. An additonal switch is used to arm system.

The only people who deride laughing gas are those who haven't got it or haven't experienced the instant pant wetting kick a proper system gives you

All it is is another way of getting additional oxygen into the cylinder so that more fuel can be burnt. EXACTLY the same as every other form of tuning.

It can enhance any state of tune engine. Tune your car as far as you can go and nitrous will improve it! For example, I imported a NOS system for my Elan project. Cosworth YB 520bhp on pump fuel, 630+ on C16 racing fuel. If and when we can hook this up all the way up the strip, the NOS will be installed to add 100bhp (to start with). 520 usable BHP on the road but over 700 on track No brainer really.

Another way of looking at it - It gives you the best of both worlds. You can have a car with enough power to have fun with but is tractible, reliable and relatively frugal. However, subject to building it STRONG, you can have as much power as you can handle at the simple flick of a switch (slight over-simplification, but you get the drift). Everyone here must have seen the Jag on TG. Extreme example but effective.

Nitrous isn't dangerous (it isn't even flammable), but some of the users are.

An undamaged nitrous bottle will NOT blow up in normal conditions. In extreme conditions (fire etc) I would be more concerned about the fuel tank!

Even us pedants have to take a holiday

Anyway, I assumed that TN69 was using NOS as an abbreviation for the comapny Nitrous Oxide Systems

£3-5 /lb

Very unlucky to get killed by exploding bottle, as they usually split open rather than explode, if this story is even true (anyone got any evidence?)

Bottle pressure should be kept between 1000-1050psi for maximum power. At around 1200psi the pressure relief disc built into the bottle will rupture so an undamaged bottle will never explode, no matter where it is stored.

old-git your so much better than me at getting your point over

Not so, I just use a lot more words -)

Anyway, what's with this twin-engined Fiat? No spec in your profile. Please tell me lots more about it. Any photos?

Work in Progress, basically cut the front off my supercharged weekend and welding it in the back of another one.

Tantalising glimpse

4WD? Power? Weight? What are you planning to use it for? Any idea when it will be working (I know, stupid question)? What Fiat is it (showing my modern car ignorance)?

 

[claymore]

the yellow car is 261hp, 20v 5 cylinder, so times two should be in exess of 500hp, santapod and a bit of track day action. its gone a bit slow at the moment, got to build up funds and enthusiasum.

 

[HDi fun]

I think the Fiat a Marea with the 4 cylinder 20 valve engine.

Try again HDi - it's a five cylinder four valves per cyinder one.

Ah, yes, the old funds and enthuisiasm problems. I am also suffering from the problem of a list of jobs from my wife which I really should do first.

Keep us all informed on progress, please.

Nice project there claymore keep us posted mate. Bet it's caused a few headaches already....

If your running a Turbod car then why not run a boost controller with a series of maps giving you different boost/power levels. That way you can have full on map for track use say which gives you 250hp, then for everyday use you could use a low or no boost map which only gives you 180. Flickable at the press of a button.

Thats what im going to use have a full on stage 3 on one map, a stage 2 map and a stage 1 for everyday use.

that's great if your car happens to be turbocharged to start with. the question was "Thoughts on NOS" not Thoughts on Turbos

 

[bonzo]

Is it quite specialist regards to fitting? If so does anyone know what ballpark figure I'd be looking at for fitting?
I've seen someone selling a nitrous kit inc progressive controller etc for about £220 (second hand from a trusted forum member on another forum) and am considering it since reading this thread.
After a bit of reading on it my opinion is that its quite an effective mod, you have power when you want it, therefore you aren't pissing your fuel away when you don't want to, but can boot it when you want to!
I know very little on this subject though, so if I'm missing something important, please let me know!

 

[turbonutter69]

If you are confident enough this is a mod you can do at home. It's not too difficult and most kits come with full fitting instructions. It's whether or not your confident enough to have a bash.

Yes....but fitting nitrous would give you even more power than the 250 produced from the turbo alone

However, horses for courses and everyone to his own. Nitrous isn't the be all and end all of power production, it is just one of the ways of getting more oxygen into the cylinders, which is what all tuning is about, after all.

Rule 1 - Make sure system doesn't run lean.

Rule 2 - See Rule 1

Ahh cool, ta.
May have to buy one of my mates a few beers and see if he can lend me a hand!
If I wasn't confident, would it be the sort of thing that would take long for a mechanic to do?

I'm still trying to find out how long a bottle would be likely to last me, any thoughts on this? (its obviously very dependent on driver).
On the 'Adding Nitrous' article on here it says "A 10 lb bottle of Nitrous is good for about 3 minutes of boost" doesn't this highly depend on how much nitrous you have set the jets to pump in? With the one I'm looking at the jets would be set up for 25 or 50bhp (more likely the latter).

 

[bonzo]

Rule 1 - Make sure system doesn't run lean.

Rule 2 - See Rule 1

Is running lean when you haven't enough petrol mixing with the nitrous? I'm presuming thats what damages your engine?
Is that what the progressive controller would prevent from happening?

Guess I should call my insurer and see what my premium would be with nitrous before thinking too much into it.

 

[steve09]

now, I think It would be a bit insane to put nitrous on my bike, its only good on turbocharged 'busa's for the drag strip.

so purely for, well, just knowing, what would happern if I were to add NOS to my 2 stroke bike.

engine wise that is, I know that it will be hard to keep the front wheel down, but as the engine works slightly different from 4 strokes,

will it blend?

 

[turbonutter69]

Mate you can get nos for Mini Moto's. So i'm sure it will work in your bike.
