Sumo: As doughboy said, the sulphur dioxide doesn't affect your engine at all... There's only a teeny weeny bit of it in there, and it's only to stop kids going to their local performance workshop and buying 10lbs or nitrous to sniffing it As for the Nitrogen turning acidic... I doubt it, as the air that we breathe and what we pump into our engines contains about 78% Nitrogen... But perhaps Dan or Nath can confirm that one...

Dan, I respect you as a chemist, and you know what? FINE... It breaks down into O* free radicals... WHATEVER. It really makes NO DIFFERENCE whatsoever, what the Nitrous Oxide breaks down into pre-combustion when it hits atmospheric pressures and boils... You obviously have no idea about Nitrous Oxide in automotive applications, and you just thought you'd stick your head in here and throw your $0.02c in, because you've done chemistry and thought it would be fun to talk about chemisty... I can't be stuffed talking about what the fcuk N2O breaks down into anymore... If you think it breaks down into O*, fine... I only know what I've read, and what I've read makes sense to me... If that's wrong, then so be it. IT DOESN'T MAKE A DIFFERENCE WHAT N2O BREAKS DOWN INTO. All it does it supply the engine with SUPPLEMENTED oxygen, (it doesn't replace anything) so we can inject more fuel and make more power. "same amount of fuel"... God help us. Seriously.

Not Ian Luff if you have any sort of driving experience... He's okay for Stage 1 and 2 when you're just learning how to drive, but if you want track tuition, he's useless. Aaron McGill or Peter Finlay seem to be the popular choices, but I haven't had a chance to goto their courses as yet

If you have an RB25, it's impossible to fit an HKS, Tomei, etc cam gear on the intake camshaft as it literally doesn't have the bolts for the aftermarket camgear to fit onto. It has Variable Cam Timing on the Intake Cam, so you can only fit an adjustable cam gear on the exhaust camshaft.

Autronic. No, the standard fuel pump and injectors won't support 600hp. None, the torque from the 3L will smash the manual gearboxes for breakfast unless you drive it like a pansy. Get a trimatic, or drive it very carefully and don't slam home the gears. What turbo? That's upto you mate. For 600hp, look to a GT3240/T04R or Trust TD07/T78

That's it.... I'm bringing a packed lunch

I might take you up on that offer I'm supposed to be my cam covers back tomorrow, if that guy still hasn't done them, I'll just get them back and ship them down to you if you don't mind doing another set in that R34 RB26 Red?

I've put up this page real quick... http://www.fortheboyz.com/tech/nitrous.php

Still no go

This section: http://www.skylinesaustralia.com/forums/fo...isplay.php?f=29 I want to reply to this thread: http://www.skylinesaustralia.com/forums/sh...ead.php?t=34793

Yeah, those tein turbos really suck... They don't make any power and all they seem to do is dampen engine vibrations............. What's that green paint and heavy gauge spring all about too??? :looney: :looney:

?

Thinking of moving upto Sydney anytime soon mate?

That is talking about combusting atmospheric air, and it talks about breaking hte bond of an oxygen molecule into oxygen free radicals. Nowhere does it state that Nitrous Oxide doesn't decompose into O2 molecules and then undergo the same combustion process... Why do I constantly have to rebutt the obvious?

Not usually. Most Dry kits just use another solenoid to bump up fuel rail pressure to supply the needed fuel. If you're using more nitrous than is safe to bump the fuel rail pressure upto, or you're going past max injector duty cycle, you should be using a wet kit, and most probably a direct port injection kit. They only changes needed to the ECU is perhaps ignition retard depending on how much nitrous you're using.

Ignoring the chemical debate for a minute, going by the above post, it's completely clear to me now that you are completely oblivious as to how Nitrous Oxide works in an engine.

DOH!!! I thought you said you prefered the polished look Okay okay, you have good taste too

That's a beautiful colour for piping... Your customer has better taste than you do, "Bling Bling Mark"

Holy Jesus........................ same amount of fuel?!?! You *DO* realise that you inject a lot more fuel in with the nitrous right?!?!?!

At the moment I'm using a Holley (NOS) Wet Kit, with a single fogger running a 30hp shot on my GTR... and it has resulted in a 35awkw power increase and MASSIVE torque increase... After the engine is built (hopefully soon!) I will push this to 75hp shot and hope for 80awkw increase... With forged pistons (I'm using GREX 87mm pistons) they should be able to handle the incredible in-cylinder pressures and temperature increases seen by a nitrous shot... Stronger conrods would help too at high revs Best is to have a direct port setup, with individual jets shooting down each intake runner, but the minimum you can run then is 25hp jets on each cylinder = 150hp shot all up AFAIK... Maybe there are smaller individual jets available now... Doughboy has told me about a plate that fits around the INJECTOR collar that squirts nitrous in where the injectors are, which I would be very interested in... Means no drilling your intake plenum for direct port injection!!!!

Heat, Water, Nitrogen and Carbon Monoxide is the result of normal combustion, correct. Or are you saying that's what Nitrous-Oxide forms after superheating due to hitting atmospheric pressure and boiling? I sure hope that's not what you're saying :looney: Perhaps we're getting our wires crossed... I'm talking about what happens to the Nitrous-Oxide BEFORE combustion. You're saying to decomposes into Oxygen Free Radicals, and I'm saying that's incorrect. It forms 2N2 + O2. I don't disagree that AFTER COMBUSTION, it forms N2, CO, H2O and heat... That's normal combustion, because the nitrous-oxide has broken down into 2N2 and O2. Well I'm afraid that there are several nitrous oxide manufactuers who disagree with you 110% on that fact :Oops:

Man... You chemistry majors are making my brain hurt And it's not fair that I'm bringing in HSC physics vs. your teritary level physics dammit!!! But I'm going to try anyway Okay, firstly, Nath you said: Air has only 23.6% oxygen by weight, the rest is made up largely of nitrogen. That nitrogen does not aid in combustion at all, but it does absorb and carry heat away. When you add nitrous, it has 36% oxygen with the rest being nitrogen. So the more nitrous oxide you add, the less percentage of nitrogen is available to absorb heat. That is why nitrous increases engine heat very rapidly. If we were to add pure oxygen (which has been tried), the percentage of nitrogen would fall much faster as more oxygen was added. We would not be able to add much oxygen before heat was a problem to control. Also compressed oxygen is in a gaseous form, so adding oxygen takes up more room and reduces normally aspirated power, and the amount of nitrogen from it. By injecting liquid nitrous, the normally aspirated power only drops slightly and it is adding oxygen and nitrogen. To put it simply, with nitrous-oxide, we can get more oxygen atoms in the engine and have a lot more nitrogen as well. Nitrous-oxide instead of pure oxygen can make much more power before heat is uncontrollable. Secondly, I read your post several times to make sure I got a grasp of what you were saying, and what you basically said was that the 2N2O --> 2N2 + O2 reaction wouldn't happen... Instead you suggest that N2O + Hydrocarbon + e- ----> N2 + H2O +CO + Heat would most likely occur. So you're saying that by injecting Nitrous-oxide, I would get Nitrogen, Water, Carbon Monoxide and Heat????? How would that chemical result aid in allowing my engine to produce 100kw @ wheels more power? Theoretical chemistry is all well and good, and you can argue gibbs free engergies properties till the cows come home but I can tell you right now that Nitrous Oxide doesn't break down into Nitrogen, Water Carbon Monoxide and Heat. If you still don't believe me, let me take you for a ride in my car Okay, well I don't know enough thermodynamics or quantum physics () to even step into the ring with you here, but I have been using nitrous for the past 5 years or so, and between installing it on the first car (dry kit) and installing it on my latest car (wet kit) I have amassed quite a large knowledge base on nitrous oxide in automotive applications. Before playing with such a substance that could so seeming easily lift the head off my engine and send it into orbit, I ventured to read EVERYTHING I could find about the substance and how it is used in engines. Some of my sources that I have read may very well be wrong, or even contradict your theoretical chemical properties, but I can tell you right now that it sure as hell isn't decomposing into an oxygen free radical and bonding to form ozone, nor is it reacting with hydrocarbons and electrons to form water, carbon monoxide and nitrogen.

I hate you all Aren't there some forum rules that prohibits undercutting and thread hijacking like this? ;)

www.justjap.com can hook you up with the boot lock... You have to buy the whole thing unfortunately, and then take it to a locksmith and get it re-key'd to your original key unless you want to carry around another key just for your boot. I went through this before too

Observers are doing their job.... Observing. Also note how the "COOK" is also just staring at the BBQ :Oops:
