Yesterday was a cold day here in the Shenandoah Valley but I was riding anyways. I stop in the at the local Kawi/Suzi shop and when I got off my bike there a Sweet looking 06 Meanie sitting there. I pulled up from the right side and saw a muzzy 2into1 and a caddman air mod. I walked around to the other side and under the drive shaft is a NOS bottle. WELL I've got to talk to this guy!
I go in and find the owner, Charlie and he's telling me that he has had the NOS system on the bike for the last 2 years. So I ask him what all he's done and how he makes it all work together.
Here's what he tells me:

He uses the PC3 with a LCD unit and can switch between maps on the fly? I'm like that's a bunch of :blah: but he starts to showing me and now I'm blown away.
I ask him how many times have you rebuild your motor and he says, never.
It has 15,000+ miles on it and has never had any problems but he says that he has to change the oil every 1,500 miles and I don't understand that.

He says that he rides with sport riders and doesn't need the extra power in the turns only but when they do a mountain run (lots of kids get killed here) and cut loose he changes to his NOS map and hits it with a 20lb shot in third or forth gear and can then hang with them.
Ok you guys are the experts here, is this a bunch of trash or does this guy know what he's talking about.

I figure the bottle was just on the bike for show but it did look all hooked up.

Thanks for your time and input.

Call me Mr Glass Half-empty, but I would have to see it in motion to believe it.

Everybody has to love Tim. LOL

That wasn't exactly what I was talking about. This pix isn't the same bike but the guy musta got his idea from this person as the setups look the same.

I'm still think Is this possible or not?

You can get a "hub" from Dynojet that will allow multiple maps and you can set it up to change maps when you hit the nitrous button. Nitrous and nitrous map "on the button". Normal map when you're not. All sorts of programmable options.

 

[streak07]

It would have to be a very small shot. We can't adjust timing so only adjusting fuel will only help you so much. Plus going much over 100hp tends to cause things to go boom, nitrous or not. Thunder mfg was blowing bearings around 115 RWHP. So if he is around 80RWHP and added 20 it's possible. Personally I wouldn't do it on a bike that you can't control timing, different fuel map or not.

Have you ever run nitrous? on anything?

Yes. Yes.

Streak07, you and I have talked about this before and I do agree with you on the timing part of adding NOS. This is such a small shot that it may not hurt the bottom of the motor even if you can't retard the timing. I guess my big question was how did he do it on the fly but billybobby answered that one. Also why would you need to change the oil at only 1,500 miles? Maybe he just thought that would help in some way? I hope to run into this guy again sometime and see if we can ride together, I would love to see him hit the go-baby-go button just to see how much faster then my bike his really would be.

I'm not sure if wet or dry systems make a difference but the nitrous gets on the cylinder walls and anything thats unburnt will get pushed into your oil as the rings go over the cylinder walls. It may not be as big of an issue with newer systems, I'd talk to some nitrous companies about it as they're the experts.

What I do know is if you get a lot of unburnt nitrous built up or you squirt it accidentally while the engine is off you just signed yourself up for a complete engine teardown and cleaning. Otherwise you have a bomb between your legs the first time you crank it. Some mazdas had a bad intake design that pushed wet systems mostly into one cylinder. By the second use of a 75 shot the few people that had done it burned through their cylinder. Found out a sensor that was sticking into the intake area shoved it into one cylinder, spark plug fired and kaboom.

Although you could easily say that more frequent oil changes are a good thing because you're flogging the engine and hitting the rev limiter a lot if you're doing nitrous. You'd never squirt nitrous and then short shift it, doesn't make sense for the kind of power you're making.

 

[streak07]

Just found it:
The reason for more frequent oil changes is for wet systems because you're spraying more fuel into the cylinders and you can cause cylinder wash down from too much fuel. If you get fuel into the oil then that's not good for oil life or lubrication.

 

[terrym95]

This couldn't be a wet system, it would almost have to be dry. Shot either in the filter or somewhere before the air sensor to trick the FI to add more fuel.

I'm not one to play with NOS, but the idea of this instead of a big bore kit is interesting.
I've never done any type of NOS on my drag car because I can blow it up fast enough without the spray.
I was sitting on the staging lane wall at Mason-Dixon dragway waiting for my turn to make a time run when the track had a clean up. This guy in a buick regal, yes a buick regal, had forgot to shut off his bottle and when he started his car back up he blew the carb out of the hood and 50 ft into the air. Now I turn around, look up and here comes his carb right at me, didn't hit me maybe that was because I was running away from it but your point about how bad this stuff really is, is so true!

Easy Hp from NOS is what most people find out to cost more in the long run.

 

[streak07]

No if he has a different map then its full time running on the different fuel map. No FI system could adjust for our air intakes so there'd be no way for something as extreme as NOS. Thats why most automotive systems have a solenoid that auto starts the secondary fuel system to go on exactly when the nitrous turns on. He just has to switch back to the stock map ASAP when he lets off the juice.

So another reason to not do it: if you're riding "spirited" with crotch rocket guys in the mountains do you want to take a hand off the bars to toggle fuel maps while looking down at your gauges?

He probably machined a plate that mounts behind the throttle body, or maybe in front of it, but thats just a guess. Pick his brain and take pics next time you see him.

 

[terrym95]

Will do! Now I've got to go by the shop tomorrow and ask the guys there how to get in touch with him. It's starting to play on my mind.

 

[DreamStreak]

It was definitely a dry system, otherwise there would be no need for a different map. Most situations where nitrous "costs more in the long run" have more to do with people not knowing how to tune nitrous. The only thing you have to do after an accidental shot of nitrous while the engine is off is disconnect the ignition and turn it over a few times. I would imagine he changes maps while he's stopped and rides with the NOS map when he is planning on using it. Could be set up with a wide open throttle switch and something to turn the nitrous off when you pull the clutch in. Then all you'd need is a switch to arm the system.

Dreamstreak just covered about everything I was giong to say.

Ok dreamstreak, stop typing so fast and give mike a chance to say something.

Ok mike go ahead:wedgie:

Check this tank out that thunder is offering now, frenched dual NOS tanks. Pricey and they would further kill our crappy range but pretty cool looking.

[terrym95]

That's just stupid! I wonder how many they sell?
I know the drag strip I go to is just full on Meanies racing:killingme
And the chain thing? The tire is cool but is bigger always better?

Aside from the cost of paint, it's still cheaper than the OEM tank! I'd rather have something like flame throwers or mini-mini-guns mounted in there than NOS, though. :silly:

But... it's got Kawi green on it, man! That makes it FASTER!!!
