hello everyone this is my first post here in the rc world. im a former drag racer who has had numerous gsxrs of all cc's. i was wondering if anyone here has sprayed there rc's? ive got everything i need to to put it on just laying around. ive got a dry kit with an mps fast fi fuel controller that opens the injectors to full rich mode when the gas is activated. i safely ran a 40 shot on my 01 gsxr 600 and loved it. i was aslo wondering if anyone knows where i can find a header for my two brothers c4 slip ons? thanks and im in love with my new bike.
I have everything to set one up on my bike too. However I did the research and I decided not too. Remember you are hucking 2, 500 cc pistons at (kinda) hi RPM's. The bottom end will not hold up....I REPEAT WILL NOT HOLD UP. It is not worth the time or the money to invest nitrous on one of these bikes. In your case it isn't an investment. They are set up for canyons and tracks......not for a straight line drag race. The inline 4 bikes take a nitrous hit way better...in my opinion.

I'm curious to how you came to the of the pistons and bottom end not holding up? And just how does you opinion weigh in on this factor....as in just how much background and first hand knowledge to do you have with n2o?
My background in Nitrous. Before I joined the Marines, I built and raced nitrous motors. I had a 1982 Mercury Capri......302 Boss (yes a BOSS). 2 stage 225 fogger. The 5 liter motor put out 659 ponies on spray. I blew that motor up in a N2O explosion. We picked the crack up off the drag strip. Nitrous is the best bang for your buck but also can be costly. That is why I put it on my race applications.
Now on a V-twin application esp a liter one........before burning up your pistons which will happen after prolonged use......you will throw a rod. Through the side of the motor it go, which will case you to dump the majority of the oil in your motor on the ground, and only bad shit will happen.
Plus nitrous is harsh on the the seals on a motor. I dont know about you.....but it you set it up and you don't blow it up...it will start leaking oil. NOT a good thing. Oil on rear tire=crash city.
Or there is a the dreaded Nitrous EXPLOSION. A nitrous explosion you say? Yep....when mixed with fuel, nitrous exploses. When a build up of nitrous is in the motor say something mech fails.....KABOOM. It will literally blow the crank through the bottom of the motor....or it could send a piston through the head. If you look at the RC where would the rear piston go in a explosion? Something to think about.
Also say you hit it....and the motor runs lean for 1/2 of a second with the spray on.......blown up......
People say Nitrous is safe and it is....to a certain point. On a track......with a engine diaper, with a pro set up, and a safety safari it is safe........Since gixxer601 races he knows all about the riskes.....now for him I would say give it hell and I want to see the dyno numbers....but this IS NOT something a non-experianced person should do. I am thinking safety all the way.

I went from pistons to the bottom end...because if you increase the engine speed with nitrous...you are making those 500 cc pistons move faster then normal. Now when you hit the N2O you hit it a full throttle. Now imagine how fast the RC revs up under full throttle conditions.....add nitrous to that...and the bottom end will give.......

Oh boy, i'm not sure where you got your info from but you may want to do a whole lot more research into it.
On the other hand, the small amount of nitrous this man is going to be running and the MPS controller unit that will be compensating for fuel enrichment duties i don't see a problem with running it. As long as the 80% DC of the injectors can provide enough fuel for the amount of n2o to be run then there is no fear of a lean out. To be sure of that just get it on a dyno with a/f readings and start out with small shots, then work your way up. Even at a 40 shot he will only be increasing the hp levels by 31% over stock. That's not extreme in the least, and should easliy be able to handle it with no premature wearing of the rings. By all accounts he should be fine and have tons of fun.
P.S. Gixxer, if you have stock headers why not take off the cans and go dyno the biatch running open. That way when you put the cans on you know you will be in a safe rich fuel curve. Besides, it would sound hella cool to run down the track wot under open headers.
Just look at the sv650 crowd for example. They spend tons of money and time trying to make their little v-twins hang with bigger engined bikes and the outcome is always catastrophic failure. The lesson I learn from them is that the v-twin engine just isn't designed to take such a blast of power.

An just what is it about the design of a v-twin that makes it noncondusive to power adders be it NA of FI?
I could be wrong, but i think more, if not most, can be atributed to people either not knowing what they are doing; or getting excited about some progress then end up putting the cart before the horse so to speak.
Factories build a certain wearablitity into their engines. This allows people to push the envelope at moderate to dangerous levels. You push to hard to fast and the life of the engine will deminish greatly at the sacrifice of performance. Instead of getting 100K out of an engine one may get 25-50K if they really put it through the paces. However, a general rule of thumb is that one can increase the output of a stock internal cumbustion engine by 25-30% without 'severely' deminishing the life of said engine. At least on any decent import or domestic engine...don't know bout Kia/Yugo/Prius/any Chevy..just kidding A lot of harley/buell and custom cruiser folks run n2o with no ill effects on their v-twins. As long as one doesn't go to far to fast then there shouldn't be an issue. The only real way to know for sure is to do it and document it. Take baby steps and build up the supporting mods as one goes for more power. In other words one shoudln't go for a 60 shot without a PC, fuel pressure riser, making sure the fuel pump and injectors are up to the task, dyno tuning, etc. I don't believe there is anything inherently wrong with the design of a v-twin, so useing power adders prudently should not be a problem.
If one wants to go for big power gains then a rebuild with beefier parts will be in order. However, a 31% increase is not asking to terribly much of a stock engine with relatively low miles. Just make sure the maintenance is kept up and enjoy the fun. Cause in all honesty such a small shot is not going to be a huge shock to the engine or drive train.
Truth of it all is that if one runs a measily 30-40 shot with the correct supporting mods, then there is no reason to worry about a failure. Its when one tries to jerry rig it, or push to far, is when the bad happens. I guess the only thing one may worry about is the cams staying together...if i remember correctly that seems to be an achilles(sp?) heel around that kind of hp, yes? I say get her on a dyno and take it as close to a 40 shot as you can safely get. Oh, and let us know how it turns out.
well im gonna give it a shot when it gets near spring time. where can i get upgraded internals forthe engine? i dont think an overbore would be a good idea for the twin with nitrous. i wouldnt mind doing rods and pistons. i doubt ill take it to the strip a lot just something fun to have for racing the big boys
I am inclined to agree with "DBD" on this issue. You are plowing unchartered territory here and when you venture into the relm of the unknown unwanted things tend to follow. If you have a bucket of spare parts lying around and you have to satisfy your curiousity then have at it. I'll even film the maiden run from a distance. All the times that I have seen shit go wrong with nitrous it puts me in mind of Hiroshima.
I am with SIR on this one, be the test mule on this one while we all wait for the results. I notice the mention of aftermarket rods and pistons. I thought this nitrous shot was going to be done on a stock motor. Now I hear the aftermarket parts chant. I too believe that all manufactured engines can be breathed upon another 25 to 30% but once you start adding nitrous, high boost turbo, or high boost superchargers, everything needs to be beefed up to take the new hit of power.

Believe what you will, but go do a bit of research on nitrous. Nothing mentioned as of yet has any sound base or factual information as to the attributes of n2o. The bottom end is not going to fall apart, a 40 shot on a 130hp motor is not a lot, size of piston doesn't matter etc. etc.
Its not charting into unknown territory until you achieve the higher hp levels that people spend so much money on trying to obtain NA. I don't see the rods stretching as to allow the piston to slap a valve, i don't see the valve train prone to floating, there should be enough injector there to provide plenty of fuel. Ugh, i'm about to type out a 5 pager here.............go do what one will. Just don't take the naysayers to heart on this one. Unless there is a serious weak link in the RC motor a 40 shot on the stocker will be fine. BTW, you won't be able to run with the big boys on a 40 shot so start collecting engine parts if you want to drag it. Problem i see with dragging this bike is that the tq(multiplied by the n2o) will be to much to put down on the strip in a controlable fashion for the first 1000ft to 1/8th. By that time the i-4's will be well on their way running you down. Reason is that they need little tq to get them moving but make better use of the hp they can get out of those engines. Point being once they are up in the upper part of their power curve you had better have one hell of a lead. Then again, you might not want to listen to me cause i don't know what i'm talking about.
I wouldn't try it on my bike especially if the word should is the only assurance that I have.
man and to think ,people use to think the world was flat!!! sounds like the fear of the unknown to me! most peeps that add the juice make the simple mistake of never tuning the bike properly,give it a shot,just take slow steps,and dont rush!the us put a probe on mars i think juice can be put on an rc51 with good results,just dont get too greedy!

Ya US put a probe on mars but how many did they lose due to gradeschool math calculations
There is a group of people that would argue that till the end. They made a few interesting points about the world still being flat as opposed to round. They claim all the photos from space are doctored to make the earth look round. Its a big government conspiricy. They claim since so few have actually witnessed earth from space its easy to keep the myth the earth is round
As for nitrous. My point was to to expect gernading a few engines in the process. Can it be done? I dont see why not. Would I do it? I dont think so but I know guys that have done it to harley motors and they held up. Just dont make those gradeschool calculation errors or youre gonna end up crashing and burning into the mars surface like nasa did a few times before they got it right.
You guys keep making comparisons to H-D motors. The RC motor is a completely different animal, with much less room for improvement. A TC88 has 50% more displacement than the RC, and makes about 2/3 the power of the RC. If you gave me all I needed for a nitrous setup for my RC for free, I wouldn't use it. If you want to drag race, the RC is not for you.
