Allen has a Boondocker turbo setup on his KX450 and is currently in the testing phase. The fit and finish on the turbo itself is extremely clean and almost looks factory. Boondocker did a great job packing everything in there. As with any model "in testing" it has it's caveats, but the bike will go straight up the hill just like a snowmobile.
If Allen wants to get into the specifics of the performance on the turbo I'll let him speak to that, but from what I saw it was pretty impressive when we rode together. He was able to boondock like the stockers and take some monster hill climbs. Of the turbos we saw in Cooke the Boondocker was far and away the most refined.

Twin skis are biased and have passion for themselves.

Ask him about the CR500R T collecting dust, carb to boot.
Timbersled will get the bugs worked out of the Boondocker some day, trial and error to the end.

Wonder what bugs they have to fix unil they offer turbo kits on the market?
I'm supriced how well my KTM 500 DIY turbo kit works! No issues so far, but
have only like ~20-25 engine hours on it. I don't know the long term reliability but clutch and gearbox seems to cope with the power. Time will tell....
Dyno run was at 10 lbs boost but for now I'm running 7,25 lbs ~85 hp.
It's very tempting to add more boost but in that case i think i would have to install a head chim. Lowering comp. ratio will probably loose some low end power. Also additional stress on the engine. Maybe 90-95 hp is the limit for those who wants a engine that lasts more than one season.
I think I will test chim next winter, race fuel is more costly and harder to get.
Havent had a chance to ride other turbo snowbikes (not a lot of them) but its really fun, especially att hillclimbing and boondocking in steep terrain. No lag and it pulls hard even in 4:th gear. Currently running 13-16-17-20 sprockets with 121"track. Next week i will install a 136" with 2,32" lugs.

KMS TURBOS
i think you will be surprised at how well the kms turbos run and provide super smooth power. I know there has been some tuning issues to get worked out but it will come soon enough.
Did you ride the two kms hondas or the 450ktm??

Any pics or video of the Boondocker kit?
In the tight slow stuff, is riding a turbo hard? What I mean is is the power hard to manage while trying to maintain a slow controlled speed?
It doesn't feel anything different than a standard bike. Currently running standard compression ratio and that makes the engine feel like a standard bike at low rpm and load, no lag and very linear power and touqe.
I think that more torqe is a bigger benefit than more hp in snowbike applications. No CVT clutch like sleds, just a gearbox.
This turbo setup makes the bike stronger over a large part of the rpm range.
I have only a boost guage and no revcounter but it seems to start boosting very early. You just ride with one or two gears higher and still have same or even more power than a standard bike.
Those who have ridden by bike felt like it was torqy and powerful but not that extreme and explosive like my MCX270 Nytro. You simply can't expect that kind of performance out of a 85 hp snowbike
But as many of you guys say: You can't compare snowbikes with sleds!
Somehow that was such and offbeat video link, I swear it's a mask on our old friend.. Perhaps this calls for an unrelated video link?
No, probably not.
No, probably not.

Sorry for the missunderstanding.
Here is the original video from 2008, when the kit was developed, just figured you all could hear the turbo releasing on the one where he passes the sport bike.

It's important to remember that before our snow conversions bikes have stayed within their displacement and general weight catergories, and as 4strokes have strived to match their preceding 2strokes in both ways. If snowmobiles were average 440 and 500cc's still even with turbo or superchargers they would be crazy fun, not explosive as Sweed's 1100 Nitro MTXxpress 270 HP!
