Nos?

[Global]

So just a few questions...

Id love a little help on the use of Nos..

Im looking at at getting maybe around the 50 plus Hp wet system for a 1000cc bike, has anyone got any advice on the do's and dont's with doing this?

Im really intrested in what brands of kits you have bought and how well they preform on the straight track (private roads).

Id also like to here about any experence with dry systems aswell, but with the size of the system for a bike i personally think a wet system may be the only way.

But im open ears on anyone that has experience.... Done it in cars but not bikes!

Cheers Global.

sorry if this in the wrong area, which i think it is, could mods please move to the right area... thanks

No, 'How To' would be the right section if either you're planning to provide step by step instructions, or you're asking for such.

That said, nitrous oxide injection seems fairly rare for bikes because you can get absolutely unmanageable power out of even an N.A. engine in bikeable size. Witness the ZX14... I'm not sure any sane person could ask for more power and yet even at rest it feels far lighter than my old Bandit.

A NOx injection system for a bike like that would be useless unless you were competing in 1/2 mile drag races or longer.

Sorry mods please move to the right area, im new to forums. Sorry.

Ive played with a few idea's fractoid, including turbo, which isn't easy to do with a carby motor. Have looked at using early modified r1 throttle bodies and after-market computer tuned for what i need if that be the case. Other

prob is I have to fabricate all the manifolds myself as its not some thing i can buy of the shelf like alot of newer bikes that you can buy kits for turbo'ing..

Lot of work and im not worried about that or the coin. Just something different.

Ive already spent a few grand on this project, and its defiantly a very rarely seen bike in perth, let alone oz and back in its day a great bike just not that popular in Oz. But has a cult following in the UK.

Um it's never enough power including a zx14 or busa.

Dry nos done with a power commander hub with map switching can work really well. Ie switch to the stupidly rich map then you've got two relays from the hub which can be turned on at preset parameters. Ie revs an throttle percent

NOS is pretty common in Perth mainly on Harleys ,two ways of doing a wet system with placement of nozzles ,either get the adapters that go into the Rubber manifolds or as i did back ion 1984 made up alloy spacers that went between the head and manifold then the nozzles screwed into it
There is a bloke in the states that does a manifold setup that sits in the airbox and shoots teh mixture through the throttle body or carb sorry cannot remember his name ,was looking at it for my s1000rr
I always turn my fuel pump on first and hit the button to make sure it is working before turning the bottle on as i am riding,hit the button with no fuel and its bye bye topend
My harley is jetted for approximately 50hp gain and run a 2lb bottle

Falcore, im still on carbies, but yeah i totally agree would be a lot easier to do with the way you describe with the PC,

but at this stage its still carbie which makes for a lot of dyno time to get the delivery of the Nos and extra fuel right, not to damage the motor. Cheers though for the heads up as i may look into the idea of turning it into injected later.

Thugs, im more thinking of setting up a rail that has injecters just above the carbs inside the airbox, maybe simalar to what you said with the guy in the states, maybe a little differant but on the same wave length.

If you remember his name that would be a huge help, to see what he done, if you can find it or remember it.

With your Harley did you source all the kit, locally?

Cheers

i believe gOzer might have had a setup on his R1 once upon a time, he'd be a good one to ask. even if he didnt, he knows near on everything anyway

[Global]

A shout out go's to gOzer, if your about have you any do's and donts on this kind of thing, your R1 was it a early R1 still running carb or was it over the 03' fuel injected models?

Would appreciate any advice from you.

Cheers for that chief, ill see if i can get any input i can on this, as there isnt heaps of people out there.

Thanks again.

Couldn't you run a wet system and plumb it in between the carbs and the block. If you have the injectors coming down at a 45 degree angle it shouldn't interrupt the flow.

[Global]

fry, defiantly something to consider doing it that way. Ill still toying with a few ideas as to which one being the best all comes down to trial and error at this point.

Anyone with any other advise would be greatly appreciated.

I think g0zer was running a 20hp dry shot...

[g0zer]

30 shot dry

its just a matter of jetting the nos same as a carb, cept you are jetting to match to maximum FI pulse width/duration. nos is sprayed as a liquid under its vapour pressure, you position the fogger so it sprays the AIT sensor. when it goes from liquid to gas it freezes the AIT and max's out the available FI pulse width. so that works out to a 30 shot on an 04r1.

mine was wired into the horn with an arm switch which is the cheapo way to do it. if i was to setup another system i would use a window (rpm range) switch, a WOT switch and arm switch. you only spray at WOT for obvious reasons if you think about it. when you have 3 to 4 gear shifts in 10 seconds you dont want to be pressing buttons, with the WOT switch you just roll off if it starts to wheelie so its easy to control. rev limiters can cut fuel, if you hit the limiter while spraying you will seriously lean out and risk engine damage so thats what the window switch is for. also stops you from spraying at too low a rpm range, cos torque = power/rpm so the lower the rpm you spray your given nos shot the greater the torque and stress on bottom end.

unless you are running long swingarms i dont see much point in massive wet shots. imho you spray to fatten the bottom of the curve not to achieve higher peak power. the sooner you are going faster the quicker your ET. if you spray a whopper shot so your bike just wheelies then you wont be able to spray unless you are at low rpm and your spray window will be very small. saving the spray at high rpm is just dumb fast and furious BS. you spend whatever it is 3/4 of your time getting to mid track so spraying past 200km/h is not going to make you much time.

i see you have a yzf1000 with carbs, i wouldnt bother nitroing that. unless you have a thing for old yzf's i would save the money that kind of system will cost to buy and setup and use it buy a later model FI superbike :p

I got mine from dynotune nitrous
