Not Average Joe Boost review

Unfortunately the sled weight won’t change after break in. I haven’t ridden the factory turbo but I know what happened to the feel of my sled after adding an aftermarket turbo regardless of the lag the sled rode heavy felt like I added a lot more weight then just the turbo.

I can’t see this sled being much lighter then the doo turbo especially if it’s a e-start sled . My buddies factory doo turbo weighed 575 ready to ride . You want boost deal with the weight, easy to cut 20-30 lbs .
My 165 slash na full load came in at 545 so I bet the turbo kit adds 20-25lbs
 
I’ve been saying for a year since I got my factory turbo doo it felt a little anemic power wise at 10,000. Bikeman stage 2 puts it about where it should be, similar to an mpi or silber turbo doo.
I’m really excited to get my boost, hoping it’s similar power as the doo bikeman stage 2-3.
Here’s a little video I did a year ago weighing factory turbo doo 565lbs, doo with Silber turbo 557lbs and my khaos with a silber 527lbs. All full of gas and oil. I’ll weigh a boost as soon as I get one. Just glad I have a turbo and NA sled to switch off on and ride for different days!

 
Interesting feedback. I've heard similar thoughts from a few other people who have had time on the production boost. Oddly, those who had time on the pre-production boost and have compared it to the production version say the bottom end has completely changed. Hopefully its something a flash can fix.

As to those commenting on the heavy feel of the sled, it has a lot more to do with lag, and weight transfer - not absolute weight.
 
Only have 10 miles on my boost but bottom end feels as good as my na summit 850. Definitely pulls a lot harder on top end as was expected. don’t have a lot of snow here yet so taking it pretty easy but first impression is very good. Pretty sure pulls as good or even harder than when my mpi turbo was on my summit but can’t try back to back so hard to truly compare. Reports say it wakes up a quite a bit once further through brakein[emoji2371]the whole power curve feels pretty smooth definitely hits hard when exhaust valves open but feels very smooth

Polaris has had a bit of history with pre-pro demo sleds being not a fair representation of what a production sled is. I remember at Arctic Man many years ago, they had cut heads on their fleet of demos to compensate for altitude. I was riding an 800 Edge, was impressed. Then I got off and looked at the hood. It was actually a 600 I was riding. Blew my mind how well it ran.

The weight of the Khaos with the Silber is a lot lighter! And also doesn't it hold a couple more gallons of fuel? That's probably another 12lbs. lighter?
 
Shots fired! There's no denying the Boost is going to be a bit more nose-heavy, and I've commented that I'd personally prefer a significant move towards less weight over more power. I'm definitely not going to judge it until I get a chance to ride one, and even then, I'd have to caveat my "review" by saying I'm not someone who needs gobs of power. For me, the question would be whether the extra power really adds to the grin factor when I hit my favorite spot on a good snow day, or it's just something I never really use over the equivalent NA sled. Some guys are probably going to find the extra weight to be enough of a burden to outweigh the extra power; nothing wrong with that. It is a very different proposition for people who ride over 10k' than people in, say, the 6-8k' range (or especially if you ride even lower). If you're happy with 150ish HP, that's something a NA 850 can make at middle elevations, but you're going to be way short at nosebleed altitudes.

I've noticed that too: new model demos always seem to get rave reviews, but the production versions sometimes leave a lot to be desired. I'd bet the pre-production sleds are more dialed in than the ones on the showroom floor. If I were Poo, I wouldn't let people ride a demo sled with misaligned clutches, for one. Anyway, I'm a little biased considering I've got a 600 EDGE, but even off the floor, those were the overachievers of the lot. The 800 only gave you another 20 HP and added 15lb or so. Would be really cool to take a Vertical Escape with a blown motor and swap in a built 660 twin pipe. Lots of people would call it a waste of money, but I'd still do it!
 
I have Fox QS3. Not too planted. It's the weight of the sled. Takes much more effort to ride. Just my take. I have a Skinz hood and Diamond S can coming for it but I don't think that will be enough.
There are a couple things at play here. Heat exchanger moved forward, Heavy can, turbo weight, new suspension calibration. All these can make the nose feel heavy.

The weight balance is definitely farther forward on any Slash model than it was on the Axys chassis - you see it clearly when forklifting them. And they seem to need more FTS pressure than what they come set at (not sure how that translates to your QS3 setup tho). Some people seem to like that because you can actually steer it a bit (as opposed to an Axys Khaos, say), but the more confident guys will likely want to make some adjustments. I think some suspension tweaking will help, but have not ridden a boost yet to comment on the feel.
 
We’ll great way to tamp down my excitement Chadly. That was my experience with my silber turbo last year when it did occasionally run “right” I still hated the thing I never could understand how anyone liked them for anything other then chute climbing or riding bottomless powder in the alpine. Rode my na Carl’s 900 most of the year. My turbos supposed to be here in January and the non turbo in February.
The good thing is I should be able to sale the turbo for at least what I paid for it.
The Carl’s 900 is going to have to carry the load most of the year again. I’m so unlucky?
Does the 900 kit have much more power than stock?

I am not sure I am happy with the new heat exchanger setup. I get the idea of centering the mass but heavier steering is not something I what out of my Polaris. They are already tough to steer in long, off camber hillsides that are too set-up and not steep enough to keep on 1 ski. In the Spring we get this in areas I ride to get to the good stuff. Also the Cat is horrible with this type of heat exchanger for dumping slush in front of the track during a stuck where it will set up and be hard to climb on top of. I have yet to try the Matryx but I really hope that new mapping is as good as I hear that I won't care about the heavier nose feel.

Had an article years ago about "PeeWee", Carl's 660 Edge 144" that was putting the hurting to the 800's of the day. Big reason I bought a Carl's 660 in my '10.
 
That is an interesting point about the long sidehills. I know what you are talking about, there is one here behind Tamarack like that. Mile or two long, can't one ski it, exhausting to two ski it. I will see what my bud thinks of his Matryx Khaos on it when we go next.

I definitely want to get back out on it and see what I can figure...don't have nearly enough seat time to make final conclusion.

I ran that stretch in January on my Khaos with the skis set to narrow. Super easy, so hopefully the turbo guys get it figured out.
