Are you guys ready for the next skidoo game changer?

[jpmez69]

It’s Bikeman !!
Would someone actually trust doing this to a $23000 sled ?

Edit ;
I see people taking a $100000 truck and doing it so ........
What am I thinking !!

What's Bikeman's mod?... Disconnect and wire the wastegate closed? lol

 

[Bnorth]

fail a rod, wipe out a turbo....boom 3-4000 dollar repair

I would say double that amount , if you could even get some of the parts ?
That turbo is Rotax

I was told an N/A 850 shortblock is ~$6500

Yikes, that is one nice thing about cat. Full engine is $4000CAD at full list price.
Few phone calls and you can have one for $3k.

ya i can get a skidoo 800 shortblock for 2400$ tax in too if you want to compare apples to apples LOL

$4100 for the extra 50cc ???

Should have factory turboed the etec 800.
It makes the same power as the 850 n/a anyways.

I really can't see this turbo setup being capable of producing much more power at altitude than how it is delivered from the factory. Many are just like "turn it up". I think you've been watching too much youtube.
The fact that power begins to taper off at 8k most likely suggests that physical limitations of the turbo, or at least where it's reasonably efficient, has been reached.
The turbo is minuscule. There is no intercooler. The air box is plastic.
By the time you replace the majority of the system, you may as well have started with a n/a sled.

yeah I don't see a point in messing with this one too much.

And you know that Ski-Doo is already working on something better to release if/when someone else releases a turbo. They are not going to sit idly by.

you are exactly correct. Skidoo wasnt going to install components that would alter the response of the machine so they could "turn it up" in the future. larger turbo etc. Like mentioned above all of the components are designed to handle not much more than 4psi of boost. Look at the plastic components for example. I sure wouldn't want to be pushing any more than 5 out of that setup. Look at all the trouble silber has with its junk plastic airboxes with 5+ lbs of boost. Rubber pressure hoses etc....

My old race sled runs 11Lbs on race fuel. The pressure components are Tig welded Aluminum piping, T bolt Silicon connectors and an aluminum welded airbox with tensioned brackets to hold the damn airbox to the throttle bodies so it doesnt blow off.

My point is the current design is not able to handle higher boost levels without reworking the whole system. and like mentioned you may as well of just started with a stock one. This sled is for the masses, not the high boosters. it simply doesnt have the capacity.

doesnt mean they wont change components in the future. Im sure that 850 will be running 200hp in the years to come. But i certainly would be leary of that the way its setup now.

There is only so much room running just pump gas.

I don't know what they could doo to make more power while keeping all the emssions certs.

Don't think race gas is an option for them.....

just to put this to rest, a skidoo 850 shortblock is 3100$ with a good core.

But Maxwell what do you consider "a good core"? They don't blow often but the ones I have seen usually look like a grenade went off inside of them.

up to the discretion of BRP but worst case scenario add 700$. Generally a good core means no holes. Scored cylinders etc is fine. So yes, if you end up with shrapnel for an engine then likely will be paying 3800$. But that was the same as the 800 too. 700$ core charge. so the 850 etec is aproximately 700-1000 more than an 800 depending on who you talk too

 

[Caper11]

You would be surprised how much pressure a properly designed plastic part can take.

Not knowing that turbo is the problem IMO. It might have the ability to produce 6-7psi.
Guess we will see how the race dept sleds run in the upcoming races.

I don’t believe doo is done with the HP of this sled, I hope BRP has flashes available in the future.

Sidewinders were all plastic at the throttle bodies and took up to 16psi+ but there design was about 10-13 so not a crazy stretch and I’m also comparing yammie quality to doo. Pump gas will for sure be limitation I suppose like we did on the old nytros they can design concave pistons lower compression ratio or a head shim but there is a point where you just have to run more boost to compensate for the loss in squish. If I pick one of these pump gas and go will be very hard to avoid. Let the Some others be test pilots for tunes.

And if you put a Rod through the block?

Just read the above comments.
So just to be clear, a new engine with no core is $3800?

And is that for a reman or new factory motor?

I have never heard of a Ski Doo motor going down.

Check out the thread, It was not the belt. It was an 800 doo engine.

Many Doo engines go down. More than any other sled that's for sure.

I dont believe that one bit, Polaris is far the worst for that. I got 6k kms on my 15 doo. No problems
