I finally made it out tonight and gave this thing a shake-down run.
First with the bad:
The CPR kit re-locates the stock 12v cigarette plug. I used this power source to run the FJO gauges as well as the Hobb switch for the IC fan. Bad idea. when you make enough boost to trigger the fan, the gauges see enough of a current drop to act up. I'll have to give the gauges their own dedicated power source.
The stock suspension settings are, in my opinion, dangerous. Way too much ski pressure. Coming off the throttle and there is so much weight on the front end that the rear gets squirrelly. A few adjustments to the skid and this wasn't an issue anymore. In fairness to Yamaha, this sled is running dual carbide Bomber skiis, but it still has too much weight on the front end out of the box.
The good:
Fuel settings for the controller were right on the money. Slightly conservative at a few throttle positions, but doubtful it is anything you'd feel 'seat of the pants'.
There is no lag. Seriously, it doesn't exist. The throttle response is unreal. I'm going to take a bit of transfer away from it for tomorow night. The 136" x 1.5" track is a monster when it finds some snow to bite on.
Under hood temps. I made this thing sing for it's dinner a few times tonight. The stuff that should be hot was. The stuff that shouldn't be, was not.
Performance. 0-100mph happens almost immediately. You know your sled is fast when you have to decide ahead of time which gauge you're going to pay attention to once you pull the trigger. Scanning them all sounds like a nice idea. In reality, it isn't an option.
Sound levels. If having a loud sled in the area you ride is a no-no, this kit is about the same as stock.
The customer that ordered this sled is a life long Ski-doo customer that came to us with a simple request. He didn't want to spend another winter getting spanked by the turbo Yamahas. He is now the spanker. He also works a crazy amount of hours. When he has time to ride, that's what he wants to do. The package that I'm delivering tomorrow will exceed his expectations (I fully expect that the first test ride will scare the hell out of him), and it will do it reliably ( on pump gas) all winter long.
CPR doesn't ship the kit with a BOV. I spoke with Jeff about this and his preference is to install a bypass valve for those customers that feel it is necessary. It is a $200 option, and you can order it that way with your kit.
Awesome job on this product Jeff!

Great post JIm
As far as the electrical Aj and I also used the panel From Painless Wiring (you can purchase thru Summit Racing) it gives you seven additional circuits on the sled that are fused. Can run all the gauges and fans off of there

I ran it last night on 4:1 91 octane and 110. On an initial shakedown I always like to have some insurance on the fuel until I confirm wastegate settings, and that the gate is functioning properly.
I'd speak to Jeff directly about what he suggests for your kit. I've advised this customer that you always want to be a few points over on whatever octane is considered 'safe'.

Thanks Art, I'll take a look at the Painless panel.

Jim, I wired in the fan to the key switch brown wire. So far, no problems.
What boost levels are you seeing?

I have the same fuse block wired in my sled. Take a look at my project thread for pictures of it. Cost was around 75 bucks. Comes with everything you need, wire connectors, 2 breakers, etc. I would have to guess it weighs around 2lbs. I mounted mine in the front of my sled. I can get a pic for ya if you need one of it installed. There isn't allot of room after my S/C install, so I had to improvise. lol

Thanks Vince. I have the pics you were asking about - I'll send them out tonight.

Good post Jim, hey Canadian Tire sells a fuse accessory unit that plugs into one of the fuse blocks and has an accessory wire on it for this purpose, have one on my RX1, the original fuse comes out, plug this fuse block in, plug the old fuse in the socket on top and wire in your accessory. Cost is around 20 bucks.
hey jim what are you using for boost controll??
I used the HKS evc boost controller and I don't like it so far. But the only time I have on it is on the dyno. It just seems to be very inconsistant

No boost control on this one, I'm running it the way it came out of the box.

Jim, make sure you have all those bugs worked out for when mine rolls in,

These are BPE bugs, not CPR bugs! I know what I have to do to fix it up, it will be completed tonight.
Too bad you're not in town right now. I could give you a test pilot on what you have coming...

I would put the fan on a Relay instead of a fuse as not to put any more load on the existing harness.
That way your just turning the relay on, about 0.3 amps (any swithched cuircut will do) and the relay carries the load from the battery to the fan.
