Yeah, it's very close to being finished now. I'm hoping to do a test and tune this weekend, if everything works out.
The BOV is from CX Racing. It's basically a knock off of the early Greddy Type RS. I've used them in the past, and they work great for applications under 12psi. Anything more than that, and they start to leak.
As far as the oil pump... I still haven't fully wired it in. I'm currently using a manual toggle. Tonight I plan to wire it to a relay, triggered from the taillight.

Well, the Nytro is back together again (picture will come soon).
I spent most of last night hooking up the wideband and datalogger, and testing to make sure it's reading right.
Also, I got the oil pump hooked up. After doing some closer inspection, the simplest route is to just tap into the main brake light wire. The stock fuse and wiring can handle the draw just fine, and you don't have to add any fuses to the system.
As of now I'm just waiting on the fix for RB Master, so I can actually tune the thing. I'm hoping Powderlites can find a solution in the next few days, so I can do some tuning over the Christmas break.

Big thanks to Powderlites!
Yesterday Dave hooked me up with a beta versionof the Rapid Bike Master software
Next week, after Christmas I'll start tuning, and hopefully get everything dialed in for the RBR.

Great project! 
Now, just pray for some darn snow.

I ride low and I was running 10 lbs last weekend. I have not had any issues with it yet but was told to start watching your AFR's on long pulls over 9 lbs so I have been. I am installing a rising rate regulator and aftermarket fuel pump to run a little more boost yet. No head shim either
To those doubting the home built turbo's. I absolutely love mine! Have 500 miles on it so far this season and it works amazing!
Nice build, I should have checked it out sooner but for some reason I don't come in the garage often. Keep up the good work, you will enjoy it!

I'm getting kind of anxious here as well.
There is a decent amount of snow on the east side of the province.
I have a feeling I'll be taking a few trips out there this winter.

Thanks. I'm really happy with how it all turned out, and went together.

so anything new? Did you run it?

Not really much new.
It starts, runs, moves. But there still isn't enough snow here to tune the sled properly... or even ride down the ditch.
On a separate note, I picked up another sled on Saturday.
Bought a 2009 Phazer RTX for my wife to ride.
If it doesn't snow soon, I might have to boot the Nytro out of the shop, and start doing some work to that one.
Confused?

Good luck lol let me know if u need help first thing supercharge they have no balls I hated mine

Ha ha. I doubt I'll be doing any power mods to it.
I don't think my wife will need the same power as the rest of us.... but we'll see after this season.
Confused?

Lol it's either power or u better be jacked... U prob won't have the same problem because ur older and stronger but last year I got stuck a lot because it couldn't keep the track spinning... Think about this the nytro is 30lbs bigger and has double the engine cc

I guess I should give this thread some closure.
I spent the last week datalogging and tuning.
The datalogging side of tuning was a bit of trouble. I had to pull out a bit of tuner experience to get everything working right.
The LM-2 is just your basic unit... of course logging AFR.
I used the analog input #1 to pull a voltage signal off of the MAP sensor (boost). I simply back-probed the output and ground to get a signal.
To log RPM, however took a bit of work. The LM-2 has a built in RPM converter, however many people (including myself) have experienced it as being troublesome. In this case I chose to pull off of the negative injector line, for two reasons. 1) Less ringing as compared to the ignition side, and 2) it will let me know when the injectors go static (RPM will suddenly read '0'. Even when pulling off the injector pulse, the signal was still ringing bad, causing the LM-2 to read about 10-14% higher than the actual RPM. I ended up having to attenuate the signal with a 10k potentiometer, then blow off the waste signal with a resistor series to ground. It now reads great.... +/- 10 RPM.
To tune it, I created a spreadsheet which converts the MAP voltage into the proper load (%) and pressures (psi or kpa). I then setup a Logworks histogram to tabulate all the recorded data.
From there the Logworks table gets put into another spreadsheet that compares the log to an 'ideal' AFR table, and calculates an error per cell. The current Rapidbike map is then multiplied by the error, which gives me a new injection map.
Here is the dash with the on board datalogger (an Innovate LM-2);
Obviously only a small part of the system, but it's the brains of the logging.
So, as of now, the sled is finished.
As it sits now;

So it runs good then?

Runs awesome.
Starts, idles and cruises like factory.... pulls pretty good up to ~5psi (where I currently have it set).
The boost rolls in FAST. I'm really happy with the turbo selection.
As you an see from the pictures, we have a severe lack of snow here, so we're taking a trip this weekend to a more suitable area, where I'll do some more fine tuning. If everything goes well, I'll be increasing the boost to ~7psi.
BTW, I did a grand total of the cost of the project.... for those interested.
~$1200 in mechanical parts (turbo, intercooler, piping, aluminum plate, couplers, bolts, etc, etc)
~$1000 in ecu parts (Rapidbike Racing, harnesses, MAP sensor) I definitely went overboard here, but I'm not regretting it at all.
~$200 in consumables (welding wire, shielding gas, cutting disks, etc, etc)
~$600 in extra parts (clutch springs, shockwave helix, OFT re-locate, maintenance parts, etc, etc)
The way I look at it, I built a turbo kit for about $2400CAD.
Looking back on it, I probably could have cut my ECU spending down to about $700 with a Power Commander system... but having dealt with those on sportbikes in the past, I felt the RBR was a better system in this case.

Any updates on this build? would really like to see the pictures.
