Boss Noss XS1100??

[T99Ford]

Hello all--

After having a wonderful experience riding the other day, and loving the power of the 1100, I began thinking... dangerous, I know!
I put nitrous oxide on my sled last winter (nothing serious, just a 30hp shot) and completely fell in love with it. I am a mechanic by trade, and I know the "serious side effects" of nitrous, but I also know how freakin cool it can be if done right. The company that made the nitrous kit for my sled also makes one for bikes. My question is, has anyone ever done this with an XS? I am not familiar enough with piston shape and dimensions to know how the top of the piston will hold up. On my sled, the top land is thick enough that it won't start to burn up until you are on happy gas for over 10 seconds. (By then your pulling over 180 horse and going over the top on the rear tip of the track!) The bike system provides its own extra fuel source, and the whole system is controlled by a external battery operated controller and solenoid. It works well. I also don't know about cooling, as my sled is liquid cooled.
Now the bike works fine as it is, I just think it would be fun to give the sport bikes a run for their money every once in a while. Call me crazy.
The system is made by Boss Noss. Here's to bottle fed bikes!!

Do it. and see if you can get over the 140 mph mark in 5th.....

I have thought about this too! Great minds think alike.

The only down side i can see it that our motors are air cooled. NOs brings lot of heat. aluminum + to much Heat = Bad news


unless you were to spray the head with NOs as well, like spraying an intercooler to drop intake temps........hrmmmm

cooling

do it on a really cool Montana evening....I've been to Butte. It gets very chilly there.

Back in the 80's, the guys from one of the bike mags tested a Suzuki set up for nitrous and blew it up, because one of them tried to shift it with the nitrous on, they were told to wait until they were n 5th gear, but didn't heed the warning. The owner wasn't happy.

I have zero input on nitrous. A friend of mine has a 100 shot for his camaro and his LT1 handles it nicely.

While were on the topic of added horsepower, can a stock standard handle a turbo. I have a dodge 2.2 liter engine that is turbo charged. I can rig up mounts and intercooler lines, but I don't know if I should try. I was thinking about the 1197 kit, but I read in here that in only gives another 10 horsepower.

Did the website search and all that comes up is a magazine article that mentions turbo and something about the YICS bikes. I was going to start another thread, but this one seems like it can handle nitrous and turbo at the same time.

The thing about nitrous, is that unless you are at WOT, you are just wasting it. I think that you could pretty easy scatter a trans. in anything but 5th gear if you were really juicing it. My sled gains about 3-400 rpm on gas, but that is more about clutching. I'm not sure what the bike would do. Also, the nitrous is contolled by a push button, usually on the LH handgrip, and is push to activate, let up to deactivate. it is very controllable, but you want to be able to run for a short period of time to clear the Nos from the engine and let it get the normal cooler mixture into the cylinder before you let off, or you can stick a piston. Noss is all about top end, and not so much for stoplight racing on a bike. This is different from a sled, which uses variable clutches for the transmission, rather than gears. You could do it in probably third to 5th, but the lower gears would be very short shots. I think a 30 hp shot would be very do-able on this motor, but you would want to run egt gauges for sure.
This system injects liquid nitrous (a wet kit) rather than injecting gas. You also have additional fuel jets and supply lines in addition to the nitrous supply.

Let me know other thoughts, experiences. I'm still debating...

In my experience with turbos, they are a more positive, longer lasting power gain than anything else, if installed properly. If you set your waste gate properly, and provide the proper fuel, a turbo would be sweet, especially on those nice 5th gear roll-ons. Most of my turbo experience has been in the diesel and sled applications. But I've seen sleds go 2-3000 miles (mountain miles, not street, pulling over 400 hp) with no problems at all. It is all in set up.

Now, turbo w/ nitrous...hmmm. Sorry if i'm talking too much!

[birch]

Not at all. I have been dreaming lately. Next to a paint job, I have my bike exactly the way I want it--Well, almost. I need some more power, or more importantly, I just want to beat my brother on his little 600 crotch rocket.

I have a gut feeling that if nitrous were installed, the old pistons, rods, and bearing would have a very hard time. I also have a feeling that the valves and valve springs would have to be beefed up a little, along with the cam. I think there is a reason why these old girls redline at 8,500.

but it would be awesome if there was a way to blow and nitrous one of these engines. I am sure it could be done, but for the price, a v-max would be cheaper and probably still kick the crap out of our blown out old bikes.

There's more ways than one to one-up your brother.

" I need some more power, or more importantly, I just want to beat my brother on his little 600 crotch rocket. "
Hi Birch,
more power can kill you. Have your brother accompany you riding his little crotch rocket as you take your bike on a 200 mile cruise. At the ride's end he will have to be lifted off it with a crane.

A Turbo HAS been done, more than once!! NOX can be done, but it's a different type of HP. My project IS going to have a turbo, with a 80 head for lower compression and heavy duty valve springs for higher RPM service. NOX at 30 HP should be NO PROBLEM for this engine.

Yeah, my 85 V-Max has 35k and the 79sf has 25k on the engine. My Max will stomp my XS but neither bike is a slouch. But the Max can get stomped by many things these days, including two or three "muscle cruisers."

I think some of you here have XS11s that would run with the Max but mine doesn't. I've got $3200 into the Max and I still feel like it needs another $2-3k. I got my 79sf for $450, maybe into it $1100 now. What could I have done to my XS for $3200?

Shave weight... chain drive..... FI..... big bore.....

I'd love to see an XS runnin' with the Max and stomping on the Zip Splats...

I'd talked about this a bit before. With the setup I am running, I have xs cylinders with an XJ head. There's no difference in the insides of the cylinders on the bikes, but on the outside of XJ cylinders, there is a bar built into the back side of them for the YICS system.

The XJ heads have ports in them on the back that fit up to this tube. These ports lead directly to an opening right next to the intake valve. The machinist that was re-doing the head was looking at it and said, "Man, that would be a great spot to hook up NOS to!"

By running the XJ head on the XS cylinders, it leaves these ports accessable in the back side of the motor. You would have to slightly gring a couple cooling fins to expose it completely. I have them capped off right now.

Here's the XJ head...arrow pointing to one of the YICS ports.




Here's an XS head for comparison...




And here's the XJ cylinders with the YICS tube on them that mates up to those ports in the head...




I'm sorry that this pic isn't very good, but this is a shot inside one of the YICS ports in the head. Up at the top where I circled, there's a hole that leads directly to the intake port of the head.




So, without too much manipulation, the NOS and extra fuel lines could be threaded into these ports and leave a pretty stock look. I had been thinking about this before. I have removed the horns to install a fairing frame. I had thought that the horn button would make a good one for the NOS...

I've posted these pics before so I appologize to those that have seen them.

I am looking at the 2008 XS11 & XJ11 calendar for May and member mathH has his very nicely modified, turbocharged, intercooled machine pictured.

Send him a PM and perhaps he will fill you in on some of the do's and dont's.

PS, I am Mr. November.

The stock XS1100 can handle 30-35 extra hp no problem, if the bike has been well serviced. Clutch will be a weak point so an aftermarket set of plates and springs will be a plus.
The ATP turbokits in the eighties could be ridden with 8 psi (30-35hp +) of boost with no modifications to the engine at all.
Higher hp levels require more modifications.
Stock cranks and rods however can handle a lot more hp. In dragracers they survived 800+ hp.
