Nitrous going on.

[Sydneykid]

Hi Belly_up (nice name, I like it), for completeness my experience has been that medical nitrous is odourless, colourless and tasteless. The stuff you get in the little bottles is too.

[Steve]

Sydneykid, I think this has a bit of potential on the circuit too - just what you need on the straight to give you the edge:)

Belly up, I would actually pay to see a dumped excel running nos - how f##king funny it would be. If only I had the extra $$$.

Lol! or one of those Proton Satrias! What sort of lunatic would ever nitro a car like that!

[Steve]

Nah, the ultimate candidate for nos, suzuki mightyboy!

Sorry Rev, I'll stop whoreing now.

[Belly_up]

i'd love to see it too, as long as there was large concrete barrier between me, my car, and anything else i valued : )

But you're right, it would be piss funny to watch in a controlled environment.

Yeah i'd hope it is, i know i'd hate to goto the dentist and have to breath in something that smelt like LPG

i was just saying that they *could* give it odour if they thought it was a safety concern.

There's one running this weekend at the RPM Drag Day @ AIR.

Supposed to be making close to around 400hp.

[Soulja]

I stand by my statment nitro = fake hp

and im not really scared of racing someone with nos, seeing as my car will be build with a 396 D-1 Supercharge (600rwhp) and if i had $1,200 to throw away i might put the 500 shot of nos (not likly).

Why nos = fake hp. u press a switch and u get a shot of 100hp 10second later its all gone, wat is the point it is pointless yes in 1/4mile it might help but on the street it wont help shit, wanna race someone on the free-way and there are cars u cant really turn on the nos. try to beat the guy u r racin' and try to controll the speed and dodge the cars too.

if u race someone without nos and they beat u and they havnt spent as much money as u have in your car i will laught my ass off.

i guess its just my 2cents. but goodluck with the nos hope it doesnt F&*&*K up your car and hope to see you on the track soon cya!

Thaks merli that helped a lot, I'll digest (and drive home).  But before I do, one more question.....

Last time I saw TRY09 do a run, they used a short shot of nitrous on the line just before launch.  I asked Mick later and he said it was to spool up the turbo against the torque converter so it had boost before the launch.  Or something like that.........

Does that sound logical?

Sorry, I went out before I saw this question...

Hmmm that's interesting... I suppose a tiny activation (perhaps 0.4 seconds? ) *juuuust* before launch would help spool up the turbo, and I'm not too clued up about automatics (and proud of it ) so perhaps you could help answer your own question. Would the torque convertor of the slushbox absorb the extra power made momentarily by that tiny squirt of nitrous?

Basically you're injecting air and fuel into your cylinders anytime you're activiating nitrous, so it's making power. That power has to go *somewhere*... In a manual, I guess it goes straight into the gearbox (or free-spinning clutch) if you're still staging...

To be completely honest, I'm not too sure about people who use the nitrous prior to actually launching. Perhaps someone with practical experience with this can comment?

Mick? Brett?

Can i ask a question

can our internals hake nos... and for how long

i know my mate had an old rx7 rotor ran nos threw it flat stick 3 weeks later he was telling me he ripped out the motor with a cro bar..

melted everything inside

i knwo routers can hake alot more punch when it comes to nos then our motors

so will it do any damage?

or have u changed the internals to something stronger?>

or will i be seeing some pistons fly down here west once u start her up??

heheh

You might like to look at my post about how much Nitrous costs to use for me over 3 years at the drag strip. Basically it's a cheap way to get your thrills, up to a point. I'm certainly not against achieving higher horsepower without nos btw. At the end of the day what we all love is g-forces.

You may not understand the reality of nitrous use if you believe all I get out of it is 10seconds. The bottle will at this stage last me at least 200seconds. Now unlike yourself I'm not really advocating street racing nitrous or not. Irrespective of whether you have nitrous or not the power to weight is what counts and how well your car is setup suspension and brakes wise to handle that power.

I'd like you to experience a nitrous equiped vehicle, if I have the oppertunity I'll give you a go of mine. I'm quite sure it will change your mind. Having said that it's fair enough not to need it when you are having a hell of a time controlling a car with 600rwhp, theres plenty of power to keep you happy (but never satisfied).

At the end of the day 'to each his own'. Opinions matter when it comes to your pride and joy so if you don't think much of nos, correctly informed or not don't get any.

[Zdenko]

thats true what rev says...

u know .. im related to alot of big v8 fans

and they tell me my hairdry'r is fake horse power as well

...

soooo y stop at turbo

i wanna go NOs one day as well..

not in da skyline tho..

in my gemi :-)

[rev210]

Zdenko,

If you know how much power the standard internals can take then don't exceed this level. Nitrous is NO DIFFERENT to any other power increase.

Eg.

Engine power limit = 500HP

Present power = 400HP

Maximum increase allowable = 100HP

That means an upgraded turbo can be upto 100HP better than the present one. OR 100HP shot of nos. If you go higher than 100HP then the internals are at risk.

The most common mistake with nos is people exceed the limits of the engine, just like people exceed the limits of boost on a stock skyline turbo. If you have understanding and common sense you are safe as houses.

Go to www.ozrace.com and check out the FAQ section on nitrous.

[Zdenko]

thanks mate..

wouldnt mind strapping some nos on my gemi hahahahah watch it go boommm ahh wel got a spare motor and box in da garage anyways

cheap thrillssss

[Cubes]

So the nos is the actual fuel therefor you don't need bigger injectors or have to worry about the AF's as NOS already has the AF sorted providing your AF's were in check to start off with?!?!?!

[Sydneykid]

Hi guys, nice to see some good stuff appearing, pros and cons,

Yep Merli, you have hit it on the head, that's where the 0.4 seconds came from. It apparently creates sufficicent exhaust to build max boost while the car is held stationary against the trans brake. The torque converter allows the engine to spin at increasing RPM. So you don't get such a savage NOS shock loading in the pistons, rods and crank. When you drop the trans brake, it is already at max boost and you use the throttle to control the traction.

From what I could tell no other NOS was used in the rest of the run, just off the line.

This adds to what Rev posted, as that engine was already at its maximum power handling capacity without the NOS, so it was only used for turbo spool up prior to launch.

Just in case you think I am going soft on NOS..........

Hi Rev, I don't really agree with your calculations about the costs of NOS versus bigger turbo, ECU etc. You can't use the NOS on the street or the circuit, but you can use the bigger turbo, ECU etc. So if you add up all the time you spend driving the car and compare it to the times that you can use the NOS, I think the value for money is pretty average.

And, before you get into not needing the extra power on the street, don't tell me that you never use full thottle anywhere but on the track. Crikey I used full throttle 6 times (in short bursts) coming to work this morning and I sure used it last night going home. You have to, to get in front of those AMG things.

Thanks for the responses guys, as usual I learnt a lot.

[Merli]

I see where you're coming from now, and I apologise for my initial outburst.

You're right, in a way, if that's all that nitrous is being used for. But that's not the case. With the extreme end of nitrous use in drag racing like you're talking about, they would still employ nitrous off the line for a few seconds to help their 60 foot times.

But that's seriously a very very small percentage of nitrous users. As I mentioned before, the great percentage of nitrous users in drag racing use it for the duration of their run, as it is easier on the engine than using a massive shot just to get the car off the line.

In fact, many drags racers opt to use a LARGER shot of nitrous, and turn DOWN their boost, as the nitrous hits a lot harder and most importantly FASTER than boost ever will...

No this is not correct!

NOS is a inert gas (its non flammable) it works by chilling the air which compresses it allowing more air into your motor it has the same affect as rasing your boost.

I dont think its recommended to ba activates at xxxx RPM

Its more like its recommended to be activated when at WOT or at something like 85% throttle, that wat sufficient fuel is flowing.

But at for example 3000 RPM on the strip, it is very likely that u would b at WOT, therefore that is why someone may have recommended it to u.
