My kit will be here next week. It is coming from Dan @ www.godspeed.bz The highest quality dry nitrous system available, or so I'm being told. No cheap components!!! The price is $335.00 or 349.00 depending on the style switch you want. The kit that uses the horn button is $349.00 The 335.00 kit uses a button you attach beside the grip. I'll take some pics when it gets here. And I'll post some dynos when I get it on the bike. (Message edited by norrisperformance on April 01, 2005) | ||

I hope it stays together long enough to do a few dyno passes :-)) | ||
| Norrisperformance |
Me too!!! | ||
| Hogs |
Is it even possible to do a dyno run with it?? | ||
| Norrisperformance |
It's only a 20 hp kit. And Dan says they dyno the bikes they put nitrous on. | ||
| Hogs |
So what does one do just hit the button in top gear ?? | ||
| Rigga |
any gear i guess...but top might be best when 20 extra horses kick in instantly lol | ||
| Hogs |
I never used it before ... But was under the understanding that once you hit the button, you have to use up the charge no pulling in the clucth, or there wd. be one LLEH of a mess..!!???? | ||
| Rigga |
can always release the button to stop the nitrous being injected i would think? so could use it in small spurts rather than using the bottle up in one go.... wouldnt pull the clutch in with it still injecting as it will grenade the motor i would have thought....but again im not fully gened up on nitrous | ||
| Hogs |
Maybe I`m thinking of it being used on the street.. and if in a panic one had to stop quick while the button got pressed and the charged was on , and one pulled the clutch in like you said grenade time.. So on the dyno thought you could only use it in top gear but I don`t know , Used Nitro before On Top Fueler HArleys and I know with that one don`t go Blip, Blip on the throtle or OFF comes the heads between your LeGs :-)) | ||

I've never had any NOS experience on bikes (nuts!) but used the laughing gas on my '96 Mustang GT. I used an NOS two stage system jetted for 75 hp. Some considerations you will want to make: 1.) Make sure you get plenty of fuel, you might have to upgrade injectors / pump because NOS makes your fuel burn faster theirby leaning out your engine. 2.) Consider switch so that the system will only come on during full throttle (maximum fuel and safely in gear). NOS has them, I mounted mine on the throttle body, but don't know how you would do this on the bike. It's not like in the movies where you push a button and all hell breaks loose. NOS is very smooth (at least it was in the car), but use it in moderation because it is rough on your engine. Good luck, keep us posted. I've never heard of Buell on NOS, with all the torque you might want to consider wheelie bars!  | ||

Hmmm.... 150shot. hehehehehehehehe Motor would probably blow up but it would be a hell of a ride for the time being. | ||
| Rigga |
im sure ive seen somewhere some dyno runs from a guy running an xb on nitrous.... not sure if its here or on the uk buell site.....looked impressive but the longevity of the motor im not sure about | ||

At this point, there seems to be some debate among some key people about running nitrous on the Buell. The question is, will the air temp sensor the Buell uses in the air box, work the same as the mass air flow sensor on the xbrand bikes. Here’s the idea behind the dry shot system. You spray nitrous in the air box or air scoop and when the mixture passes the sensor the ecm will add the needed fuel. I was just told nitrous is like a 150 degrees below zero when it leaves the nozzle. There seems to be a lack of testing, on the Buell system, so guess who decided to be the guinea pig. I will be receiving and testing a beta unit from one of the big hitters. In addition to the nitrous system from www.godspeed.bz Dan at Godspeed will be doing testing as well. I should be done with the SS Drummer testing next week if everything goes smooth. But it will be a couple weeks before I get everything for the nitrous testing. I ‘m excited about the whole deal and hope to bring you guys some good news. Any input would be greatly greatly appreciated!!!!! (Message edited by norrisperformance on April 01, 2005) | ||

ok heres my input do it do it !!!! | ||
| 99buellx1 |
Hook it up to the passing lamp button. It will be like a trigger switch. | ||

Just got off the phone with Dan @ Godspeed. He assured me that any closed loop system would work with a dry shot of nitrous. The key is too start with a 10hp shot and make sure the a/f values are good. You can keep adding more nitrous until the bike starts to run lean. He said 20hp, no problem, and very safe, as long as it is used properly. He seems to really no his stuff on nitrous and turbo systems. (Message edited by norrisperformance on April 01, 2005) | ||

found the dyno chart of the nitrous xb.... knowledge vault under dyno graphs and mods made a guy called stefan f posted it up..... very noticable difference between normal and nitrous runs | ||

"Any input would be greatly greatly appreciated!!!!!" It's only closed loop at "mostly" steady throttle opening and at idle. The closed loop running sets the AFV and when you wack open the throttle it moves to open loop and uses the stock map modified by the AFV. In the case of the Buell, the AFV acts "quite a bit" like a MAP sensor, but once you go to open loop by getting on it, it uses what it learned (where the AFV ended up) for fuel delivery... It's not "exactly" a closed loop system. It's a hybrid. It's only closed loop when you're tooling around. Go WOT, and it's all of a sudden an open loop. | ||

If this is true then it's back to the drawing board. Man you know, that explains a lot about the system taking it's time to relearn when a change is made. But I still have a ace in the hole just can't talk about it yet. Thanks M1 | ||
| 1badxb |
why not just trick the computer and make it closed loop all the time??? if this is done then the bike should use the input from the intake air temp, and the o2 sensor for adjustments right??? i am all for the nitrous sign me up | ||
| Norrisperformance |
I have a system being sent to me for testing. It should take care of the problem. Before M1 posted I couldn't figure out why I needed it. But now I know: how could I have missed such a key point in the conversation about this new system. I actually stumble on the opportunity to test for this company. It want be long before it will be unveiled. Man how did I exist, before the Buell and the BadWeb. Thanks M1 | ||

I've run a 57 hp wet shot w/no problems. Had to run colder plugs and pull a lot of timing out to be safe, but it worked well. Before that I had run 75 hp with zero issues on an inline four and pushed a 100 hp shot on my personal bike with very few problems (even did a 140 for a friend). Wet systems solve the hp limitation problems of the dry systems and eliminate the lean condition risk of relying solely on an air temp sensor to enrich the system (after all, you get more enleanment that just the 127 deg-F temp drop from nitrous - lots of oxygen released in there!) You might want to see if they are willing to experiment with a high fuel pressure wet system. Just my $0.02 | ||

You are right about the temperature. One of the benefits of nitrous is the extra explosive power. The other one is that it has an immense cooling effect on the incoming mixture. Colder air is more dense which allows you to stuff more air into the cylinders. | ||
| Chris_mackay |
Wouldn't the stock fuel pump be able to supply enough extra fuel to make it a wet shot? I would think all you'd need to do is route an additional fuel line to the NOS injector. ??? | ||
| Craigster |
Good point Chris. Problem is the stock solenoids from NOS or NX are designed to lift against a max of 15 psi of fuel pressure. You need to change to a solenoid capable of lifting against 50 psi at bare minimum. Back when I made my own kits all my solenoids were capable of working with high pressure EFI fuel systems.....my 12 volt fuel solenoids were capable of running up to 110 psi of fuel pressure. That puts the limitation on the fuel pump. They arte available, just more expensive and puts more of the research into the installers hands as very few companies provide high pressure EFI kits (Nitrous Express does provide them) | ||

When using Nitrous there really isn't any reason not to go with a "wet" system. Dry systems are what caused all of the negative stigma that still follows nos around. In the old days lots of people with no knowlege grenaded there engines by going LEAN when they hit the button. The button (usually the horn button on a bike) is a momentary on switch with a safety (arming stitch) on your throttle body that locks the system off unless you are WFO. It does not lock on at any point, unless you have done something very very wrong. Please consult with someone that specializes in nos on bikes when installing a kit on your bike. It can be a lot of fun, but only when going straight and standing straight up. bottom line, be careful, don't be a statistic. | ||

hwy not run a twin tank system: on NO2, and one propane, inject together. fuel and oxidizer. matched A/F ratio. | ||

Wet systems cost more. But may be the best answer for the Buell. Spraying nitrous pass the air temp sensor will only cause more problems. The manual explains the FI system just like M1 said. It is an open/closed loop air / fuel control. So ecm will not compensate for the nitrous over 5000 or at wide open throttle. And if you sprayed it, and you where not at wot and below 5000 the ecm would adjust and store that information, and the bike would run rich the next time without the nitrous. It looks like its going to work with beta system thats coming as long as you spray it at wot. I still have some issues, but thats what testings about, right. So far you guys have helped a great deal already! Thanks | ||

what if you could use a WOT throttle switch to turn on a TFi and N2O, basicly you would only be running on your race computer around town, and when you arm the N2O and the WTO stitch is on it will turn on the Fuel and the funny gas..... does this make any sence at all?? hope so....would it even work who knows???? |
