Boss Noss XS1100??

[T99Ford]

This is great to talk about. The ports in the YICS head would work well, but you would have to find fittings to get it all to seal properly. But it would be direct injected. Check out the Boss Noss system here:

Nitrous is a different kind of horsepower. Like I said before, it is primarily for WOT applications, and pulling in 5th gear. Its main advantage is price over the turbo kits. However if used properly, it can work well.

I was wondering about the clutch on the XS being strong enough to take it. I think this is primarily why you would want to only use it in 4th or fifth gear. All the fuel and nitrous needs to be delivered directly to the cylinder, as was mentioned with the YICS system. You could install the fuel and NO2 nozzles inthe carb support boots. All the fuel and nitrous delivery on this particular system is controlled by a "smart box" It works well on my sled, although my sled is EFI, and adds fuel differently.

Nitrous is not something you would really want to mess with if you did not have a thorough understanding of carburetion and engine operation. The turbo would be a much better bet if you lacked experience and knowlege in tuning, since you could set it up once and leave it alone. Nitrous is more finicky and could lead to alot of problems if not set up properly and monitored constantly.

Let's see... Price or ease of tuning...

back in teh late 70"s while i was at school for hondas we built alot of Turbo Bikes from little 400"s to a few CBX"s they all would run fast but all had same problem they didnt want to stop. i know i can completely modify the other 11 i have but by the time im done only thing left of it would be a engine. I have my CBR1000 ans it is built to be extremly fast iwill never be able to push it to its limits. Unless its on a race track. I will go with a big bore kit, a set of reprofiled cams, better clutch, and il up grade brakes, But its tsill a beast t almost 600lbs .But its fun to see what folks will build on here. and thats what makes it interesting.

I used a tap and threaded them to install a counter-sunk allen plug.




These port holes are aluminum and could be threaded easily to any size needed.


That being said, Nitrous would be awesome to have at the quarter mile track, but not very practical for every day riding. For something you were going to ride every day, the turbo )In my opinion) would be the way to go.

could somone please hook me up with the turbo kit infor. I have searched the site, but have found no threads that specifically deal with turbocharging one of these bikes

[birch]

Never mind on the turbo chargin questions. I found this thread doing a search (finally).

Anyhow, here it is:

Lorax, did you ever successfully modify for turbo?

[The Lorax]

No, my lovely and gracious wife sold the car out from under me before I could harvest the turbo out of it. I still think about putting something together from time to time, but no concrete plans at the moment. thought about looking @ my local M/C one yard for a totalled seca turbo as all the appropriate plumbing and such would be there. might be a little small for the 11 but every little bit helps. besides, what's the worst that could happen . Have a nice day and ride safe.

Hi Lorax,
the worst? That you manage to get a 30% power boost with your turbo conversion which will drive your bike another 15% faster that it's already past the safe limits of it's cycle parts and you survive the consequent wreck as a helpless quadriplegic with no insurance. I truly hope this fate is held from you, but you did ask.

[The Lorax]

Yes, you do have a point there however, if I ever get into a wreck of that magnitude, the good lord has given me a small insurance policy that will prevent me from surviving. You see, I have a congenital bleeding disorder, which in a nutshell means that even a small wreck will very likely kill me. it is something I was born with, and so I choose to live life, even if it turns out to be a short one. Yes, logic would denote that I have no earthly business being on any motorcycle of any kind. I have come to accept that I'm an imbecile, and that I will subsequently die a loud gruesome death. I do however ride in a rather mild mannered fashion....that does just happen to be my personality, not really fear of anything. I just got old and lost the "need" for speed. I still like to ahve it available to me, I just don't have the occasion to use it very often. so again, I pose the querey, what's the worst that could happen. Haave a nice day and ride safe.

[T99Ford]

Yes, and given that we all understand the inherent dangers of riding motorcycles (most wrecks occur when another driver takes right-of-way, etc) lets think about the best that can happen. If you are on a bike, you are certainly not looking to prolong your life by doing so.
The best is that as you are riding to your death, you will be yelling at the top of your lungs "Wow, what a ride".
Lets all remember that our bikes were designed to run on little fuel, at moderate speeds, and for a veerrry long time. Any mods at all will shorten and change that original end. But they will look cool, turn heads, and make us feel powerful for a little while. And isn't that what the motorcycle is all about?

dang it! I drained my deep thought tank for the month again

[The Lorax]

Well said, I feel very much the same. I have a fairly healthy respect for life in general (and the alternative), so I don't think one can truly "live" their life sealed in a glass case. My parents had vision enough to see this, although mom doesn't approve of everything I choose to do (smoke, ride a motorcycle, spend my life repairing equipment in Steel mills) she knows that she and Dad raised me to be as "normal" as possible. they didn't rush me off to the hospital every time I scratched my nose, or fell off my bicycle. I see alot of parents of kids like me doing just that. granted, the good lord has given me extraordinary health considering the circumstances. In the '80s, people like me were dropping like flies due to HIV. thankfully, I escaped with only a couple hepatitis viruses and for that, I feel truly blessed. I am not a really religious man, but I am fairly spiritual and do not question the existence of God under any circumstances. I am truly happy to be alive and do my best to enjoy every day of my life. what better way to enjoy life to the fullest than on one of these lovely beasts we call the XS11. Once again, I seem to have gone off a tangent, and semi hi-jacked a thread. sorry folks, I think this one was originally about nitrous oxide systems vs. turbochargers or some such. myself, I think I would prefer a turbo as the waste gate can be set and left alone, and once the appropriate research is done as to how much boost the stock internals can take, and low end lag is sorted out (make it a supercharger ) the system is set and maint. is kinda minimal, no changing bottles and worrying about weather enough gas is being injected with the nitrous. I vote turbo / Super. that's all I got (I know, enough already) have a nice day and ride safe.

For the HP seeker, lets not forget about Dan Hodges current 1311cc big bore/sleeve project. I have a feeling that thing is going to be a MONSTER! We haven't heard anything out of him in a while. I wonder how it is coming along.

[DiverRay]

Lorax,
The 650 Seca turbo is too small for the XS1100. You could try and put two of them on, but there is no room. Hugh Maguinnis(SP) wrote a book on turbocharging that is a MUST READ before you go too far. My copy is in storage at the moment, but I CAN get to it in less than an hour, including riding time. Garret Turbo also has a GREAT web site with tools for matching a turbo with an engine.

Thanks for the heads up Ray, I will do some research. I am still many moons from actually being able to make anything work right at the moment. but I am always thinking of ways to build a better mousetrap. some are worth the time (I usually lose them before I can put pencil to paper), others not so much. I enjoy coming up with ideas and trying to implement them. I very much enjoy working with my hands, but do not have the best fabrication skills in the world, but they get a little better with each failed project. I made this piece for the tail of my XS last year that attached to the seat (in place of the stock tailpiece) it had the tail / brake light, turn signals and license plate mount built into it. I installed it and removed the rear fender altogether. looked pretty good for a couple weeks until the welds broke and I ended up running over the piece that had the lights and stuff in it. it was a trifle embarrasing, but hey live and learn right . have a nice day and ride safe.

I don't know about the actual hooking up to the bike, but ANY positive pressure in front of the carbs is going to boost the HP. It may not be as much as you would like, but anything that would change the situation of vacuum drawing in the air, versus positive pressure blowing it in would be a gain... even if it was just a pound or two of boost.

In essence that is true, but you forget about the technical limitations presented by the turbo itself. The one from the Seca is designed to be propelled by a certain amount of exhaust gasses at a given rpm. If the seca reaches max rpm the turbo will be spinning at a certain speed close to its limitations (more than 100.000rpm). If you double the amount of gasses that propel that same turbo, going from 650cc to 1100cc), it will spin up to a speed that exceeds those limitations, probably doubling the speed, and result in a wrecked (read: exploded) turbo AND ruined valves and pistons.
