Looking to install NOS dry

[BigRid]

I have been studying this forum for a while and its a great community. One thing I havent seen is a topic on NOS; It is so inxpensive, and can add some serious HP, but definately has some inherent risks associated with it such as destroying your engine for instance. What if it were used just on a once in a blue moon track day, are the risks still too great? Could our bike handle the excess heat. Thanks guys

Used on a track day? You mean a drag day correct?

I wouldn't do it personally, but hey... it's your bike and you can do what you want.

I wouldn't do anything more than a 25 hp shot until you figure out how the bike will respond to the NOS. Check your sparkplugs often for signs of detonation. You might find it beneficial to run higher octane fuel through your tank when you plan on spraying NOS. Premium fuel will help prevent detonation which can burn a hole right through your piston.

In stock form, the FZ6 motor puts out approximately 95-98 hp. Adding a 25 hp shot is a 25% increase which is quite a bit when you stop and think about it. The stock internals (crankshaft, bearings, connecting rods, pistons and cooling system) have a certain capacity/ design limit.

By adding additional HP, you're stressing those components to a higher degree than they were designed to handle. If you go too far, you'll run the risk of burning a piston or throwing a connecting rod right through your engine block.

Not trying to bash you and if you want to do this be my guest, but I have to ask 'why'? Why do you want/need NOS on your bike? I don't even think most tracks would even allow it.

Not knowing your riding experience/skills, most would say (myself included) that if you want to ride faster, take that NOS money and invest it in yourself with riding/racing schools. When you see guys on 500cc bikes slaying guys on liter bikes, it becomes very clear that HP isn't everything. :thumbup:

I wouldn't reccomend it either, unless you are going to modify and upgrade the engine.

Don't get me wrong, it would make for a pretty cool mod and you would be the first to do it on an FZ6 by the sounds of it, just don't want to see you blow up your bike for it. Is the risk worth the gain.

Yes I mean the occasional trip on to the drag strip. also does anyone know if it is illegal to have this on your your bike just regular street driving not using it on the roads of course?
I was also wondering if there is a difference in heat between the wet jets or dry, i just wanna cover all my bases and figure out any way of making it safer, cooling methods etc even though it is probably impossable to cool it effectively given the insantaneous heat build up.

Wouldn't it be cheaper just to buy a faster bike? That way you're not likely to blow up your engine...

The reason is simple, the bike goes fast enough, I'm just looking for a good clean way to enjoy my time a little more. We are probably all on this mod forum looking to improve our bikes, and maybe ourselves in doing it.

I've found NOS kits for under $200.00
The Majority are under $400.00, thats not even 1/20th of a new faster bike, bsides its not about dying because you put on more than you can handle, its about a relatively cheap mod that increses HP and I can say I did that and its a hobby.

The trick will be adding fuel as needed when the nitrous is flowing. The stock ECU is not going to know how to cope with Nitrous.

thanks...I was looking to post that thread.

Good luck! I wouldn't want it, but HEY, it's yOUR bike and it would be badass...

I would think that the power commander could be used in conjunction with a dry shot to increase the duty-cycle of the injectors (assuming there is margin), maybe via a gear-specific map or triggered input by your NOS activation switch. Or maybe you can "redneck" it by fooling with the MAP sensor output to trick the ECU into dumping more fuel under high load (assuming again there is margin in the stock map and you can do it in a way that the fuel trim when running closed loop does not cancel it out).

I would experiment with how much added fuel you can get to dump in before deciding to add NOS though, that is too nice an engine to blow up . There must be some equations around to compute how much additional fuel is needed for comparison.

This is an excellent point. One of the limiting factors will be how much fuel the injectors will flow.

Lol me too! I would ask fz6fighterboy some questions about how he made his. He's obviously very patient and happy to talk about his bike going on the way he reacted to the gyp he was getting! :Flip: Just read the whole thread first as he answers loads of questions on it and probably won't be happy having to write stuff he's already written before.

You'll see straight away that he did quite a bit of strengthening etc to his engine before NOSing. However - I'm sure our bike can take a bit more than it does as it's a 2004 R6 engine that originally put out 123 HP.

dude... dont take this the wrong way, but go get a book and read a bit.. there is alot more to nitrous than the differences in a wet kit vs a dry.. I have had nitrous in several cars, and its not something i would suggest for a bike. the simple fact that when the "shot" of nitrous get to the engine, the power (depending on what your set up for) could be a little overwelming and you could esentally just flip the bike over. that would probably be the best case... go read up on how nitrous works, how it generates power.. and the much debated differences between a wet kit vs a dry.. once you know how it all works, then you will be able to figure out how best to utilize it for the fz6 if its something your serious about doing...

for the money.. it will be expensive, but i would go with a wet kit with (most important) a fuel preassure safety switch and a full throttle switch.. i probably on the fz6 (someone have a stock dyno chart??) never use it below 6K-7K due to the sudden rush and the liability of it creating too much pressure for the engine to handle.. i only think you could really do 15hp more before you have to do some engine buildup.. and this would probbaly cost you in the relm of $1000 at least and you would need some dyno tuning time for it to work all in sync.. its a little more complicated than the fast and furious make it out to be.. you dont just go "hey lets put this on" and expect it to work the way your intending it to.. hope it help.. good luck ..:thumbup:

I have researched this a good amount, many people just see nitrous and say hey it'll blow up your engine. I plan to just put on 10HP nozzles and that is plenty. I read from that link people keep posting about streetfighter that our engine can handle more HP than it uses, but I really want to know if our stock fuel injectors can handle a 10HP shot., anyone know its capabilities. I would really like to stick to adding a dry kit if I can and want to know if this is going to work. Thanks for the discussion guys, see ya.

 

[LERecords]

no its not going to work... a dry kit is very dangerous toward a good engine... ust adding nitrous without adding more (and the proper ammount) will cause the engine to run lean and possibly detonate.. if you are going to add a kit, you need to seriously think about spending the litle extra and just get yourself a wet kit.. much less chance of detonation and you dont need to modify your current injector setup.. a 10hp shot should be fine for your bike... but your going to need to tap for extra fuel, shouldnt be all that difficult.. but remember that you can't use nitrous unless the throttle is open full or if the is a drop in fuel preasure.. these safty devices will ensure that you wont cause any damage to the engine... but seriously.. i have to ask.. do you understand the fundamentals of using nitrous... do you realize how it works and the concepts of rich/lean air fuel ratios... if you don't id be more than happy to post up some info which'll be helpfull in designing asafe, but effective nitrous system...

I say if you want a drag bike, get a Busa. If you want a faster bike then get some more training on how to ride the bike you have. My personal opinion is that the NOS experiment is only going to end badly. Either with you doing backflips down the highway while your buddies drink to their former friend, or you drinking to that bike you used to have while you watch it melt into a pile of plastic and aluminum.

I've used NOS, though not in the FZ6. Frankly it didn't do much other than the engine ran smoother and the spark plugs got more deposits on them and failed quite often. I'd say go to your local small airstrip and see if they'll sell you the highest octane fuel they have.

I know right.. i have used it to and it really only movees the rpm neddle faster... acceleration and not speed... but it is a fun thing to have in a car.. i really dont know if i personally would put it on a bike, but its all possible...
