Nitrous

[J-DADDY]

Hey guys, in case others have similar leanings I will be installing a Dynotune system shortly. Before (Why, oh why, etc.) the comments-I do not consider the fJR all that powerful next to bikes I've ridden and I have owned several drag bikes with nitrous in the past. This system is a bit different because it is a "fogger" that works through the airbox instead of manifold intakes. I've been intrigued by it and because I can never leave anything alone...you can guess the rest. It alters the fuel delivery by tricking the air temp sensor in the airbox into adding fuel. Also, I have a Techlusion to add more fuel if necessary (also works well with a Power Commander). I'll be going with a dual bottle set-up, so if any interest, stay tuned! :yahoo:

Karmac -

I gotta say you are a wildman!! Please keep us informed!

Don't forget to back out some timeing,,,,,damd ecu will not make that easy. Talk to fuel moto ,maybe they can help with the powercammander.. Watch out for the squid on the liter bike with a turbo and monkey gas.

 

[TCMike]

Dude, you are playin with fire. Carefull not to get burned. On the other hand.....sounds interesting, just not something I'd be willing to risk .

 

[Phugedaboudet]

In-F**king-Sane!

We want pics-installation, testing, ride reports, dyno before and after....

How long until we get the Supercharged FJR?

heh, instead of "Ride it like ya stole it!", this guy's motto can be "Mod it like ya own it!"

 

[Bustanut joker]

Because he can.... Nice touch Fred! I think it's about time somebody took the plunge.

Looking forward to the results too.

:jester:

 

[odot]

Yeah, pics of a piston with a hole burned through it would be kick ***.

 

[Bustanut joker]

Hey odot, why doncha nitrous up yer *** razor next time you shave yer anus? Bet it'll save time :lol:

:jester:

 

[odot]

I just don't need the nitrous to put me to sleep whilst tryin to shave me nus.

Finally!

This thread got some value!

HAhahahahahahahah!

Yeah... NOS, superchargers, turbos... <yawn> It's all a bit passe. You want to really impress us? Take your FJR to

for a bit of re-work then we'll talk!
Hey, Warchild! Now this is your next ST platform..!

Those bikes are cool from a technology standpoint, but they need some work in the style department :blink: I've seen the clip of Leno riding his - if I remember correctly he said that throttle inputs on that bike aren't instantaneous, so you really have to think ahead as it can take a second or two for the bike to begin slowing once you roll off the throttle.

Did anyone else notice the guy in the video SockMonkey posted doing 200mph speed runs in jeans? Some people have more balls than brains. <_<

Try to answer the questions:

No piston or cam changes immediately. Did all that in the past, but not trying to accomplish the same here. Of note is that I ran a KZ1000 with nitrous (a lot more HP than in this case) and no problems with pistons.

I don't expect (does anyone ever expect?) overwhelming drive line, tranny stresses because there is always margin for error, I have found Yammies to be tough (note the FJs that are used for sprint cars, etc.) and I don't intend to go higher than 30-40 horses at this point.

Why the FJR? I have it. I have done it with other bikes. Actually put one of the first turbos on a Kawi I had eons ago. Not many, if any have monkeyed with an FJR yet.

Fuel metering-whatever the sensor does not account for, I will adjust with the Techlusion. The Techlusion does not work well with a dyno-it's more of a seat of the pants adjustment and you see the story on your plugs.

For those of you here who have used nitrous-unless you hit it in 1-3rd gear, it is not what I would call a "kick ***" power that would highly load the tranny, shaft drive (etc.)-it is a smooth, "gathering" type of power. I hit the button as I'm already at WFO throttle. DO NOT hit the button in low gear, you will experience more excitement than you desire.

The largest issue I am facing now is that the airbox of the FJR is deep and the intake tubes extend from the rear, providing a space for the nitrous to get behind the tubes. As a result, I fashioned a rubber gasket that blocks off the rear of the airbox, but is not airtight. The crankcase breather hose (etc.) enters the airbox from the far/top end and I don't want to create a vacuum, just ensure most of the nitrous stays up front by the tubes and sensor.

Another potential problem is ensuring the nitrous enters the box equally so the intakes draw equally-I don't want one cylinder running differently from another. There are numerous options-shooting into the center of the filter so it is diffused equally, removing the filter from it's current location and filtering the snorkle, or squaring a filter off to cover the square filter opening, or shooting into the snorkle opening. Sounds like fun?

Numerous suppliers including Dynotune insist that I do NOT ****** the timing with this set-up.

I considered doing this to my FJ, but it would not be a fogger and I haven't done it with a FI bike, so here goes.

Biggest reason-I simply cannot leave anything alone. I crave the speed I do not have with the FJR. Not always, but sometimes. One of my previous set-ups-I used an electric shift and because it basically "jumpstarts" the bike, the mixture of exhaust and nitrous would gather in the pipe in that split second and ignite at each shift. One time a guy racing me at night almost jumped off his bike (I had him by a number of bike lengths before hitting the nitrous) when he saw balls of flame flying at him out of my exhaust!

Anyone who has ever been tucked in WFO and has hit that button will not ask me why.

As I go along I will pass on info and provide pictures.

Cool :clapping: Do it :yahoo:

Karmak,

This is the first NOS system I have ever heard about that doesn't require timing reduction.

Which system is it? You got a link? Brand/make model?

Interesting,

Shooooooot! Nitrous? Take a real challenge, solid fuel rocket motor. Once it's lit, you don't stop till the fuel is spent. Now that's a challenge.

 

[raclow]

DAMN, put it on a ramp and try to ride it over the Snake River.....should get some real height to clear the bluffs. You are one crazy dude...I hope it works so we can enjoy the story and pics.

Good luck with this endeavor!!!!

Just out of Curiosity, why Nitrous on a FJR ? Do you intend to Drag race it? If not, what is it that you are trying to accomplish? I guess that I must be getting old! . . . although, in some ways, it would be a lot of fun to have a really light weight (if that was possible) FJR, with a stock appearance, that made 200 rwhp, and capable of humbling all the squids on their Gixxers. It will be interesting to hear about (and hopefully see) what you accomplish, Keep us posted.

you don't need to add any hp to embarrass squids on gsxr1zrcbrr's, you just need to have skills. oops, i mean skillz. squids by definition don't know how to ride well if the road has any type of curvature to it.

but i understand your point. it would be pretty cool to blow the doors off a corvette/viper/murcielago when you're both in triple digits. ( :

And I thought I had the need for speed. The FJR's top end is north of 150mph. How fast do you want to go? Where are you going be when you hit the nitrous button? West Texas? LOL.

I would love to see it when it lights off.

karmak,

if you ever decide to do it with your fj, please come visit us at the yahoo list. lots of engineer and otherwise handy folk over there. one guy is putting fuel injection in his fj. heck, come on over and discuss it on your fjr, even.
