Might be this one?

that sled and owner is from here in weyburn. seen it in person and it is unreal. millionaire oil tycoon.

Yup NM's Pro works well. However in the deep during our Golf Game when all the chutes were 3' of fresh he waited until the 4 strokes made a trail. His quote went something like this "if I knew it was that deep I would have brought out my Driver (Apex)".
FYI......Cam Hicks Pro just had a new Crank installed last week after most of the season.

Lighter.......yes
More speed.....no
More reliable.....no
Funner......maybe depends on what fun is to you.......torque if fun for me
I know I have over 40,000k of boosted 4 stroke in the mountains......2 failures. 1 Chain 1 Primary.......success for me.

Ride what you want......its your money.

Safe sledding

have yet to see a guy hold the throttle to the bar longer then cam. stock or turbo'd.... put quite a few miles on with him this year, down the trail, side of the trail, up a hill, into a hit, on the landing, pretty much everywhere he goes except when hes in the air, he has it to the bar!!!!! and those boys put a stupid amount of kms on in a season....but i agree, shouldnt have done a crank already.

 

[Deano670]

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
RS

This one doesnt have that same fuel box thingy:d

I'm a 2 stroke guy obviously but Fuji has been known to hold it to the bar for extended periods of time as well. I think the year he won his Extremy he climbed a chute that was the longest vertical climb ever recorded. Something like a minute and a half or better on boost to the peak. The 2 stroke boost segment will grow but I don't see them being as reliable as a 4 stroke whether it be a Yammer, Doo or Cat. Just sayin'.....:d

It does however have standalone fuel injection.

Ya pretty much bang on!

 

[NM]

To answer the question that was originally asked...from what I have seen, the Cat's seem to be the easiest to tune and may be the most reliable. The 2011 Pro RMK's are much stronger than the previous RMK's, probably because they have such low compression. The new Pro is tricky to tune, but can be done. There is a big variety of turbo kits out there, and some run better than others for various reasons.

Looking good!! but I thought you said no pics!!!!! :d:d:d:d

 

[powderpilot]

1,600 miles on my Twisted M8. Two sets of reeds and a boost line. Some guys are stacking the reeds, but I like my bottom end. I'm running the stock M1 reeds, they seem to last about 700 miles. Still running pump gas on 6.5#s. I have spent very little time on the box, it's been super consistent

 

[I Dare Ya Rene!]

Ya, the 2 stroke turbo has improved in performance greatly in the last couple years, just not enough torque or reliability yet. I have 14,000 km(fairly hard km) on Turbo MCX Nytro in the last 2 seasons. I have broken one chaincase and had one stuck MCX injector. Earlier this month I towed out 2 dead 2 strokes and one pissed off rider(guess who).... at the same time!!! RS

 

[Vertical-Extreme]

I love my 2 stroke turbo, and have put alot of trouble free miles on her, but when you get in the deep snow there is no comparision to the boosted 4's. the 2 stroke turbos have came along ways in the last couple years, and I think I am going to be on one for a while, but like neal said some days it would be nice to pull out the "driver" especially when all the other guys you are playing with are swingin the big club lol

Sweet setup Deano !!

So to get this back on topic. IMO and how and many more times do we need to beet this dead horse. Yes guys we all know the fourstrokes work under boost. They have for years and they always will, the two stroke game bird of a different feather all together this is apples and oranges as far as i am concerned. Four strokes have always had the advantage of there fuel and electrical systems right from the factory,which the two strokes are still lacking at. That being said there is a HUGE difference between a stock two stroke turbo engine and a PURPOSE built two stroke turbo engine.(ask BDF) and for the fourstroke guys who say look at all this bolt on power BS still need head shims,low comp pistons, rods and the list goes on. So apples to apples a turbo built four stroke engine vs a turbo built two stroke engine IMO very comparable. My two cents for what its worth

I and 90 percent of the guys I ride with have a head shim, and run 17 pounds all day on pump gas(I actually run purple gas- marked premium the last 2 seasons). Stock pistons and stock rods. What we are saying is that the 2 stroke turbo is really workin well on the M8 for the last 2 years and looks real promising on the Pro. Essentially sled cost, turbo and install are comparable, performance and reliability are not comparable. The Yamaha Turbo will surpass the 2 stroke turbo in all aspects except one, landing huge CB and GK drops. Not really a factor because 99 percent of the sledders won't do the real big jumps primarily because they like their teeth attached and the convenience of being able to walk and dance the Horizontal Polka!

I agree with Deano but a lot of people aren't only comparing apples to oranges but oranges to peaches and peaches to grapes as well. Here's my thoughts for what they are worth.

Everyone compares different factors, so its up to each person to determine what they are comparing. No two people are alike. The sleds and the power they make are 2 very different things, one makes big torque right off the bottom, the other one doesn't. One weighs more, the other less.

Reliability - sure we know who takes that trophy - 4 stroke

Weight - same deal, you know the winner - 2 stroke

HP - kinda tricky, built motors and who built them are very different things, is a 2 stroke backyard tuner gonna hang with a Hurricane Dave special? No but two average guys running low boost might be closer than you think.

Simplicity - Operationally - built in EFI and proven systems, win goes to 4 stroke. Installation and maintenance - hard to compress those 4 stroke valve springs with your thumbs, top end on a 2 stroke is like 1/2 day job, win goes to 2 stroke.

Cost - Operationally - goes to 4 stroke. Initial investment - goes to 2 stroke

All depends on the factors that you put the emphasis on. If you want a light sled that you can work on yourself, you buy a 2 smoker but you will have to put some $$$ into it sooner down the road. If you want a sled with loads of torque and never want to touch the thing, you buy a big boost 4 stroke. If you don't care how much it weighs and your ride at high elevation, you might prefer a 4 stroke for reliability but have a Cat dealer next door who builds a lot of turbos, you buy a 2 stroke because you have local knowledge, parts and help, you will buy the 4 stroke if the reliability factor means more to you than having a local dealer.

Conversely you might want a light boosted sled that boondocks well and that you can work on in your own garage (because you are mechnically inclined), so that's what you buy because those factors mean more than reliability. Or you don't get it and you buy a Yammy because you only have a Yammy dealer in town. Not saying that Yammy's can't boondock or that all 2 strokes need a top end every week, but every comparison is often biased because guy A will put a big emphasis on one factor or another, but guy B doesn't care that much about those things, he wants factors X, Y and Z.

My point being that the debate can never be "won", because everyones selection of factors is different. Ride the piss out of what you got and don't worry about convincing the next guy about which is better!
