Well been working with him on the Doo turbo, This guy is a class act for sure! What ever he says he is going to do he does! That is hard to find that anymore these days!! And with Dave Dunn and P.L. by his side this is a killer set up for us sledders!!!

Thank you so much keep it up!!!

No problem Matt, what is even more rare than someone doing what they say is some one who appreciates what has been done!!!! Dave Dunn and I will not stop until we have done EVERYTHING in our power to ensure that the Powderlites turbo kits are 100% for the sea level user!!! thank you for your support and appreciation!

Dustin

BTW my goal for your sled it to be ripping up my 1/2 mile test strip by next weekend...big goal but EVERYONE needs goals!!!!!

Stay tuned

Right on buddy!!! When you sent me pics on how you are treating my sled i was blowen away!! (covered up every night WOW)

Thank you Skydog

Couldn't agree more! I tipped a few sodas back with Dustin last season up in Hayward then some time messing around with the Turbo at Dave Dunns. Quality guy!! I will definately be working with him when I decide to pull the trigger on the turbo.

Up at the Mach Z shootout Dustin was very helpful when I needed a hand. He's a good guy but I wonder if you have him install a turbo for you, will you need to take out extra fire protection on your insurance policy?

No no my sled is fire proof!

Skydog P.S. Things can go wrong to any one, look at Nasa......

Read into that anyway you choose....

Have you started my build yet?

Ernie got all your parts laying in my shop, going to start on it the 2nd tuesday of next week...lol.....You have to buy another ski-doo before you can build it!!!!! Any luck with the stutter yet on robbies sled?

I had to take a break from Matt's sled for a week, finally quit raining down here so we can do a little bit of fall harvest..only 2 months late...sheesh! Maybe if someone asks nicely Matt will post some pics of my progress on his build. I have been sending him pics of the progress till I had to do my real job for a while....bummer!

the parts are piling up!!!

A few pic of the 1200 getting ready for head shim.

ONe more

No luck on the stutter - I haven't had much time to play with it - but so for it doesn't work. I'm going check all my wirining next as I have it wired different then I did with the MSD - the RB3 needs a ground to activate the stutter - the MSD has the option of using a power wire which I just picked up off the brake light. If I get it to work i'm going to wire it through a relay so when activated through a toggle switch if the brake is on the stutter will be activated - just one of those round to it things, but I have a feeling I will have the MSD on it again.

Robbie

Matt, pulled the head tonight as seen in the pics I sent you, as you can tell, this thing is built hell for stout. The engineering involved in building this engine is second to none. Although I would like to kill the engineers for the location of certain bolts lol! I will have it decompressed by the weekend and hopefully start on the actual turbo install next week...later than I had planned but that darn "real job" thing keeps coming into play.... bummer..

Stay tuned

Robbie, i personally have 0 time with the stutter on the rb3 but you should be able to wire it in off of the brake light using a ground/breaking a ground with a relay??? I think?? So far the only complaints on the guys using the rb3 stutter is the range of rpm they are breaking up...dunno....btw....get ernie to buy a 1200....would you???.....please!...lol!

I think he ordered one last week - it should be here soon!!

ARE YOU FREAKING SERIOUS???????

The Rb3 stutter, works great used it on my Nytro, you have to turn it on with your lap top make sure the rpm is set right.
Skydog

WOW look at them cyl no egg shape going on anytime soon under boost!!

Head WOW look how beefy the head is!!!!

Thick sleeve ! ready for boost

Has anybody figured out the stutter issues with the RB3 on a 1200???

I've got a friend that uses the RB3 on a GSX600 for racing, but he's stumped as well. Plus, the Rapid Bike HelpLine is a joke ... they have no idea what they are talking about.

Man like i said used it on Nytro it worked great and was very easy to use. It is the same on the 1200.... Must have Rapid Bike pro software.

Skydog

Yep ordered a renagade but won't be in till mid Dec

Head all done !!Update pics!!!

And the Installation takes off!!

yes I have the rb3 stutter working
I am not happy with the 600-700 rpm loaping
we will have a alternative soon

Pretty productive day today for having to do my "real" job as well. Installed the header, turbo, turbo oil pressure and return lines, both of the turbo coolant lines, exhaust pipe, mocked up the intercooler, charge tube, throttle body, intake, ecu, pre cleaner and a few other parts and pieces. Skydog has a few more pics. Tomorrow my goal is to wrap up the install on the front of the sled, plumbing up the blow off valve and boost controller......stay tuned!!!!!

Junky

more fun stuff!!!

More

Last one today..

Looking good Skydog Should hopefully be as good as your last ones. Interested to see how she runs. How many pounds are you thinking of? To bad out your last thread, Sheetwright, aka dumper

Hey buddy!!! Yes too bad about that thread.... Yea hope she is as good as my Yamahas have been to me!!!
Skydog

10PSI pump 20-25PSI race fuel!!

Nice.... TOO much in common now. After Pat gets done on mine I am thinking of having Rob dial my RB3 and prologger setup in..

Front all done!!

Only quesion I have is when the third
Merc going to show up on the back of that cat?
Sled Looks good to
Nice Job.........

There is no air movement across the fins of the intercooler from a fan or air coming in when the sled is moving.

I'm always wondering if there isn't a better place to put the air intake. Every kit seems to have the air intake on one side of the intercooler and the turbo on the other side. As the air gets sucked into the airfilter it draws air across the intercooler from the red hot turbo. The air intake might draw some air from the nose, but for those of us that run the sled in lots of snow, the intake has no choice but to pull in the red hot air from the heat put out by the turbo sitting on the other side of the intercooler.

Is there no other way to get a better location for the air intake? The Yamaha system of intake and exhaust piping seems like it was built to have a turbo added.

How i ride it is perfect. Super cold air going in to turbo, then the next coldest air is hitting the intercooler! I might even add a few holes in the nose we will see. At 50-100Mph the air hitting the nose is alot more than you think. But you could put the filter where ever floats your boat, i love it where its at.

hahah a 3rd Merc on the cat, yea i know a guy who did it not worth the money, it kills the set up and bal. With spinning the props,weight, tons of drag from the center motor. (it is a true cat no center pod) I think he gained like 4-5mph..... The hole shot and mid would be insane with 3. But it is unreal good with 2. She runs 85MPH in a 1,000 from idle.

Thank you Skydog P.S. Does this count as 3??? haha

There is TONS of room for air movement upfront and the grated plastic in the front is rather large to allow for plenty of fresh cold air, not even going to be an issue. the pic doesn't do it justice!

You are going to owe me a ride in that boat when this is all said and done Matt! I did the powerboat thing in the late 90's with a small scarab...fun while it lasted but when everyone traded their 32's for 42's-47's I was out! Too far out of my league! I went to the Ozarks almost every weekend.....not any more fastest I have been on the water was 116 on my buds 47' Black Thunder...she rolled pretty good!

With Dunn have H1N1 I am pretty sure I won't get the rest of my parts/ tuning bike today but I bet I still end up being able to fire it up....more pics this afternoon!

STAY TUNED!

Any time on the boat ride let me know!!! Wow sucks Dave got the bug, hope he gets well soon!!! On stand by for pics and info!!

Thank you Skydog

That sled is going to be sick skydog! Well done skidoojunky looks awesome! Glad i didnt shake daves hand thursday night. Hopefully he gets better soon.(not that its going to stop him from working)

Well had an awesome day in the shop today! At approx 5:32 pm Skydog's sled took its first breath of life as a boosted, yamaha, arctic cat, polaris eating BAD A$$ MACHINE. Heat soaked it 4 times and luckily not even so much as a dribble of fluid anywhere. Even on the test stand where it is impossible to build much boost that thing sounded wicked! It rocked itself as I whacked the throttle as if there was an earthquake! No doubt Skydog is going to be impressed with this set up! Now all I am waiting for is the Polar attack and tuning bike so I can write a map that is sufficient enough for him to play on the grass till it gets cold.


This was my first complete install and I would say that if I were to do it again with 100% of the parts there i could do it in about 12 hours by myself. Nothing overly difficult just A LOT of time consuming steps to ensure that everything fits properly and there are no leaks. The step of the head removal/cam timing was what I dreaded the most and it was a walk in the park with the proper tools. Once again this motor is simple....strong....and like I have said before it is like the 350 chevy of snowmobile engines! It is the motor that is built to be messed with...bring on the modifications!


Later in the week I will find time to complete his sled once the tuning bike and Polar have arrived, My b day was Thursday and wifey got my a new Flip Mino (pocket camcorder). You would think she can read my mind or something! I will try it out with Skydog's sled chewing up some sod on my 1 mile test strip!


Oh yeah BTW for any of you guys that remember I am expecting twins...I found out Thurs ( yeah my b day ) that I had better get to buying mini z's cause we're having 2 boys! YEAH BABY!!!!! It doesn't get any better than that!

Talked to Dunn today, he is back amongst the living, rebuilt 2 mach z's with Dale Larsen yesterday afternoon...looks like he is going to make it afterall...what a WUSSY!

Thanks for the Rear View of the Cat.Very nice.
You are right trips not cost effective at all But fun.......
Its all hole shot ,center engine is up too high for real efficiency even with a small center pod.
Had a 24' Skater with trips
The sound of 3 V 6's on the chip is something to behold.
Able to suck down 100 gal of fuel per Hr
Like the Junkie friends moved into bigger and to support the sled habit
Moved back into a more cost effective ride.
No worries about frontal air with the new venting systems out there now days if necessary.
If not easy to stick a temp sencor in the air filter for Proof.
turns into an issue fix it .....no issue,no worries.

Dustin,

I'll gladly pay you Tuesday for a Powderlight turbo install today!

That pocket camcorder will come in handy on your next visit to Phipps. I just got one of those helmet mounted Contour HD cameras.

Happy Bday in advance congrats on the boys!

Well frist off again like to stress how fun this has been with Dustin!! He is a joy to work with, calls you all the time with updates/pics!! Just a great guy, and i knew when he rolled up in his CLEAN trailer,truck and his sleds where spot less!!! I found the right guy, this install will be as clean,o.e looking as it can be i know!!!! THANK YOU!!

And thank you to all you guys on here for all the nice replys, i feel Doo talk has moved in a very good direction!!!Last year or so So a few more pics and a sweet video coming soon!!!!!!

Thank you Skydog P.S.Will keep all you guys update with and little changes,races, or upgrades to make things better....if any................

Hey Fellers,

One of the other builds reported two issues, and I'm curious of you ran into similar stuff:

(1) Exhaust temp or O2 sensor bung was missing on exhaust
(2) Exhaust circuit has fitment issues

Maybe they've resolved them, but just thought I'd ask...

Looks great!

MtnDoo

Looks like low boost fuel on the bumper.

The bung was on the exhaust pipe..no sweat there...did have one little issue with the header but I spoke with Goldy at Powderlites and that issue has been resolved as well. My only complaint is those darn rubber boots connecting the air filter to the turbo. Cutting those CORRECTLY took about ten years off of my life! Cutting those was like trying to wrestle an earthworm! I think I invented a few new curse words in the process, but they are on and I think all things considered they look pretty darn good!

Black Toys.....didn't reall have too much liquid boost on this build...concentrating too much, mine is next and there will more than likely be more beer spilled than wrenches turned. Is your sled done yet...I need to see some pics! If I know you there have been many attempts at building a better mouse trap, I am sure that thing is BIG, BLACK and SEXY!

SDJ

Did you leave the motor mounted in the chassis to put the head shim on?
