They are getting better but still not as tuneable or reliable as the four stroke applications.

next season is gonna be my first on boost....after riding with reid from boondockers and seeing that m8 go....hard to turn it down. espicially with the new timing thingy BAHAHAHA. run up to 9lbs of boost on 91. at least thats what the owner of boondocker canada told me....im no mechanical guru, (timing thingy lol) but this kit is the closest thing ive seen to pull and go. no need to screw with stock compression either so you retain your bottom end power.....

after a few seasons of seeing the T-M8 run well I am considering putting one into my xp. 200+ pump gas hp in a 'doo chassis would be the ultimate sled for me....saw a C3 carbon fibre xp with a boosted M8 in it on boulder saturday, it was all I could do not to beg to take it for a spin. a dude from C3 was there helping set it up, the guy that owned it was lowmarking it around turbo hill....hurts my head seeing a sled like that not being milked hard like it should be.

Low in the torque dept, don't mile per hour like a 4 stroke, but they get around ok.........until the snow gets deep ;)
Reeds, Pistons and Cranks still an issue. And the fuel box thingy is getting old. Few run consistent.

14,000k on my 08 Nytro and still running stong :)
Happy Boosting

could have fooled me by some of neils videos with his polaris pro... mind yea he probably does not have the milage but apples to apples they will hang with a t4stroke

and light! for all intents and purposes a stock "feeling" sled. there is a reason you see way more boosted 4strokes than stock ones in the mountains because they suck as stockers. the 2 stroke is light and nimble, add boost and it gets the best of both worlds. they don't require 700mph track speeds to do insane ch!t because they are a hundred pounds or more lighter.

can't say I have seen any 14,000km boosted 2 strokes....but I have seen some 4 strokes with dropped valves etc long before that mileage. too costly to rebuild, so guys look for used stockers to buy and use the motors from.

Once boosted, 2 strokes do go through reeds and once a year pistons and from what I hear a crank every second year. If you ride lots of km that will add up pretty quick. It all equals out, so pick whatever you like to ride and enjoy the huge hp they make. Once you go Boost you will never go back.

bigdawg's dragon got updated pistons on warranty (not because of any failure), and hasn't skipped a beat in 3 seasons on boost. people say a lot of things

Seen M8 turbos go through 4 pistons 2 cylinders and a set of reeds in one season. Any of them can have issues. I do know big dawgs works well so does bdf's. Km's tell the real tale. The crank issues is a hear say. Ride what you are happy with and if it's boosted it will be a blast.

Rode with many turbo 2 strokes in the last few years. I concur boost is the way of the future in sledding but I assure you they will not hang with the turbo 4 stroke. Put many miles on with Chris Brown( one of the best backcountry riders in the world) on his 2 stroke turbo(race gas) and me on my pump gas 4 stroke turbo in deeeeep pow! If they were as reliable and would "hang" with my Tyammie I would be on one! Rene

Two different beasts, and a big difference in price too.

I agree, once you go boost, you'll never go back!!!!
