Boss Noss XS1100??

[T99Ford]

At your elevation, do you have to mix race gas in order to prevent pre-ignition with the nitrous? I have been able to get by on 91 pump gas in my sled, but that is from 6-10,000 ft. I suppose that you could be riding at that height in CO. I
I have been very happy with the Boss system on my sled. I imagine that the bike would be the same. I think that in my application, a turbo would be better than nitrous, and much mre useable. Nitrous would come later
Where did you pull lube oil for the turbo from? The other question I have, is were you able to get the intake manifold from harley, or did you have to make one.

Thanks for any info!

Fuel

I have too much compression to run pump gas and a turbo 10.25-1.

It also limits how much boost I can run.

I did add a couple base gaskets once to the cylinders to lower the compression, but it made it hard to start and increased the boost lag.

It is setup to run 8lbs of boost right now but it will run quite well at 12lbs. That much boost also requires an even higher octane (116) and true leaded fuel. That is where I made my big numbers on the dyno.

However Nitrous likes compression and it naturally cools the intake temp.

Altitude, I have lots. I am at 6200 ft and right on the foot of the rockies.

I am using a very modified RC engineering kit the intake manifold plenum was ready made. The actual intake manifold that attaches to the carb bolts to an adapter plate that bolts to the turbo (the manifold comes with the carb)

The oiling comes from the oil feed that goes to lubricate the head. it return flows to the oil fill plug.

It's raining today but when the weather clears up I'll take a pic or two if you want.

Please take a couple of pictures. I'd really like to see what you've done.

I don't know how to upload pics but I put them on photo bucket.

Tell me what you think

Looks great. How does it perform? Have you raced it against anything?

[JustJeff]

performance

Runs REAL STRONG

It is still a heavy bike compared to modern sport bikes.

I run out of gears way before most sport
bikes.

30 -130 it is very hard to beat.

I have gone up against a friend on an R-1.

He beat me out of the hole and I had a hard time making the difference before I ran out of gears (almost). But. 30 mph roll -on and he got small in my mirrors till about 130.

Boosted

very nice jeff very clean install, has to be a blast to ride we use to exeriment with turbos when i was in school for Honda in the 70"s.very nice Bike

Very nice. What made you choose the XS to put your time and money into?

You still have the shaft drive. Imagine not running out of gearing after doing the chain drive mod! Perhaps your bike would benefit from a 750 rear end swap?

[JustJeff]

Being different

Anybody can go out and buy a busa and bolt on a bunch of parts and have something sickeningly fast. It will also be like every other bike out there.

No real skill involved, No challenge. Somebody else has done all the hard work for them.

Doing this much to an XS11 and getting this much from an XS11 requires actually knowing what you are doing and WHY it needs to be done that way.

Modern sport bike riders don't respect old-school bikes... That is till one of them bloodies their nose LOL

[The Lorax]

Well, Jeff, it would seem that you know your stuff. your bike is banging, wish I knew half as much about how to make stuff go faster and such. props man, me gusta mucho.

Nice bike! And good to see the RC engineering kit, very rare! I have only see them twice on an XS1100 as long as I can remember.

[JustJeff]

Turbo Kit

Thanks for the complement Math. That is high praise coming from somebody who built the monster you did.

The RC kit I used I found in new condition. I wanted it BAD. I actually got it through a trade deal (would have traded my Kidneys). It short cut everything I was trying to do. The pipes and plenum are stock everything else has been changed at least once, to one degree or another (waste gate, impellers housings ect.)

I have been looking for a good Ignition system that will give me some additional tuning capability like boost retard and variable advance rates. Looked at a few but tring to balance price with function.

What did you use?

[Mathh]

In 1994 I had the Electromotiv Tec I installed. It incorporates 2 direct fire units instead of the standard coils. The injection and ignition are both programmable and are interconnected. With the previous Haltech system I tried the standard coils interfered with the ignition so I could not get it to run at all (only with the coils 2 ft from the bike ).
The tec I is old compared to the new products they offer now, but it does the job.

Hey, I don't have any experience with NOS or Turbos but if your looking for a programmable ignition/injection setup you might want to check out the Megasquirt. Its DIY and as programmable as you'll probably want. Someone even fitted one to an XS already, there should be a link to the guys web page in the tech section somewhere.
