CanD TURBO

[Seanextra]

Interesting i still have GT 25 and i also had a set of FJR Throttle Bodies that i was going to throw on my XJR but now its all changed and im back to using the stock FJ Carbs and decided to Turbo the FJ instead. I bought a low Klm Set of Piston and Barrels from a late model XJR1300 with only 10k on them Forged Pistons with Nicosil Bores apparently all the go for Turbo stress and heat disapation. All the trouble to get the EFI right on and off boost scared me off the EFI sure i gather it must be the best set up if money or tuning is not an issue but from what my research has found that a correctly set up blow thru Carb set up is far easier to get close to right by paying attention to the venturi to carb pressure that compensates for the boost equally and if you are an old school mechanic such as myself at least i understand what i need to do to get it right. There is some great info out there but very little about Turboing FJs the odd XJR has been done but Turbo FJs although out there don't seem to get on the Internet. Good luck with your build and you should start ( or have you already) a FJ Turbo thread resource pages where we can log any of our issues and findings so at least other wondering soles turboing FJ 1200s may have a decent place to start looking for info.
I found these great for basics
and there is a section in turbo-bike for pressurizing the R1 carbs which have the same connections as FJ/XJR carbs

Hey Sean.....nice to meet you .....maybe I will see you at the rally in March. When I got back into riding some 4 years ago, I started prowling the web for sites that catered to the FJ specifically. The first site I stumbled upon was a site called FJ Modifications uk. It was here that I saw so many awesome projects and modifications. When I saw what Frank Moore (racerman...aka...Kookaloooo) did to the FJ..... I was hooked. Then I read an mod by a guy named Bob Shammas out of Michigan and the Turbo mod he did to his 84, I was tremendously inspired....lol......my very first bike was an 82 Seca 650 turbo which was the little brother of the FJ.......so when I decided to get back into riding again....the FJ was a natural transition for me to resume where I left off. The information that Bob Shammas posts in his write up is incredible......lists every hick up and glitch and posts all the results as well as the solutions and Dyno charts....although his set up was a draw through set up.....there is still a cache of invaluable data as the entire process is constantly upgraded from stage to stage. I am quite sure you will find his data most helpful. I am really looking to run the girl on 6-15 lbs of boost at any given time.....it will be a challenge but the one thing that Bob said while summarizing the project(s) was that it was incredible fun and it did not disappoint. Being a carpenter and not a mechanic, I have a very limited knowledge of bike engines....but I am learning and I think that that is half of what is all about....plus it seems to make friends out of strangers........and I love that...

Sean.... found this on one of your old posts:

"Hi All ,
         Well im stuck in Bathurst still working, never had a chance to attend even via tin can, bit depressed I missed the first but has made me more motivated to shift planets if need be to attend the next.

  So what's the plan for the next one so i can move off from the depression of missing this one ?

Regards Sean"

Hoping you have seen the plan for Bellingen next March - its a bit closer for you southerners this time. SO..... how about it?

Are you IN......have the planets moved?


Cheers

Do you know if Bob is any better after his accident. Donated a few £ to his rehab fund a year or so ago, wondered how he was doing..

I just had a peak at the site last week hoping for an update....but it looks like the last one made was almost a year ago. I find it ironic that the accident happened on a dirt bike travelling considerably slower than had he been on a street bike. At first when I heard from Barry (from FJ Mods.uk) and he told me about the accident, I immediately thought uh oh........ the turbo got away from him..........but such was not the case......... I should write Patti and see if there is any news....will keep you posted if I hear anything.

PS....What's Barry up to these days....I was hoping to hear from him after CanD was finished......sent him an email but looks like the letter got lost or the email address was changed.........

Last time i chatted with Barry his focus had shifted off of motorbikes and onto old muscle cars/drag racing and it was taking up the majority of his free time....I believe he said something about a 70's model camaro and a big block.


KOokaloo!

Yes done deal Harvy this time in 2 weeks time i finish this 13 hours a day 6 days (nights) a week night shift ! Never to return to Slaving going to get me a job with Bank Hours for once,  However as i have indicated to the General i may not be able to attend aboard any Yamahas both in deep rebuild , Might have to ride the my Troublehead Hardly Davids son its ok i promise to park it out back or around the corner!

Regards Sean

PS this Just Arrived !  will have these available early next year for about $150 bucks each, Very high Quality Reproductions of the lower Chin Scoop/fairing for 3CV etc.. im going to get side scoops done as well i just need a pair to take the molds from my company's International base in Hong Kong makes RC helicopter and Jet Fuselages and CNC stuff these have really top quality manufacturing and use WEST SYSTEMS Resins and Fibres also to be done in Carbon Fibre for those with too much money. SO any Australian members want to donate Side Scoops for 3CV in exchange for a Reproduction set and ill give the originals back after molds are taken ?

 Having Trouble Posting a Pic here will see what i can do tomorrow !

At one point I was collaborating with Steve Conklin on putting fuel injection on FJ's.  We made up some sets of adapter manifolds that used Hayabusa throttle bodies.  Those are particularly good because you can disassemble the bank of throttle bodies and rearrange them to put the bell crank back in the center instead of on the end.  I think they are 41mm bore?

When I sold my FJ I sold all my FI parts to Chris Wyatt:  Throttle bodies, adapters, rubber manifolds, Hayabusa wiring harness, external fuel pump, and some other stuff.  The electronics is not so bad, as you can buy a plug and play Megasquirt based ecu from Tony at Interface-PNP  http://interfacepnp.webs.com/hayabusapnp.htm.  You can replace your complete wiring harness with the Busa harness, or build a separate sub-harness.  Chris purchased one of these Busa ecu's for his project.  Not sure where he is at with it.  It would be perfect for a turbo, as that is what Tony developed them for.

The Interface-PNP box runs Megasquirt MS2-Extra code, which allows you to configure for the FJ crank pickups.  Full control over fuel and ignition maps, based on throttle position and/or MAP pressure.  I run a similar box on my supercharged Aprilia twin.  Once you figure them out they are very easy to tune.  In fact, it has an Autotune function, that uses a Lambda oxygen sensor/controller input to tune your bike as you ride.  It works really well.

Conklin used a Microsquirt variant.  I don't know if he still has it, but he might want to sell it if he does.

So it's actually been done?  I have yet to hear confirmation that anyone has actually got an FJ running on EFI.  I figure some speed demon may have actually done it for a race bike -but I have not even heard confirmation of that.  What I really would like to see is an EFI daily driver FJ.  Again, I just have never heard confirmation that either race or daily-driver, currently exists or even has existed at one point.

Please fill me in if you know of an example.

I wonder how hard it would be to use the FI model XJR head so you could use the cam signals for running sequential injection?
Batch injection which uses only the crank signal (think wasted spark but using fuel $$) is ok with a turbo, but a wasteful for normally aspirated.

There you go Sir. I have asked these dutch guys are helping a little with my base set up.

VDB Works

The motor uses KMS ECU as do I.

Hard to tell from that video what kind of motorcycle it is.
Wonderful shots of the cobblestone streets though!
That bike didn't look like any FJ I have ever seen, but maybe the engine is based off the FJ engine?
