M8 Turbo vs M10 Turbo

[Colorado Climber]

Gentlemen (of course I use this term loosly),

I have a problem and need your help. I will be purchasing this week either a 09 M8 162 or a 09 M10 162, both sleds have zero miles. The plan is to immediately install a PG/RG turbo kit, probably a Twisted. This is a substantial upgrade from my previous sled, which was a 07 800 Summit X 159.

I live in Colorado and ride from 8200' to 12,000'. I spend about 80% of my time boondocking and 20% hillclimbing. I have been riding all my life but have never owned a turbo and am not mechanically inclined. I understand that the M10 allows you to run lower boost which equates to better reliability. I also know that the M10 is significantly heavier then the M8.

So my questions are:

-Is the M10 turbo a good boondocker? Will horsepower negate weight in a boondocking situation? Should I be concerned about the additional weight?

-Would you exchange weight for reliability? Or vice versa? Why?

-I understand the trade-off is reliability vs horsepower. With what I've stated above, what is the boost "sweet spot" that I should set given my mechanical ineptuted?

-What would you do if you were in my shoes? Go with a different sled? Different Turbo? Go in another direction completely? Why?

Thanks in advance for all your feedback.

Well I can give a partial opinion, I own a 2010 m8 turbo which I am dying to ride...., and recently just sold 2 of my other m8 turbos, so I am very familiar to the m8 turbo which by the way is a blast I will never go back to a stocker again....

Both of my turbo's were trouble free and most people I talk to are not having very many problems either, besides reed valves, exhaust seals and spark plugs, are fairly maintenance free...

Also considering the fact you are coming off of a stock sled, you will be amazed with the m8 it has more than enough for most people. They leave a permanent grin on your face that is very hard to get rid of
I also have owned 2 highly modified m1000's which were a gas to ride but the weight diffrence from a 1000 to an 800 is noticable for sure.

My opinion go with the m8, you will not be dissapointed,, I think most will agree.. but then again I have never rode a m1000 turbo..

twisteds pump gas m1000 is just plain scary for a sled you can fill up at any gas station for 20 bucks. very seemless usable power and bulletproof. there is a wieght difference but i think a skilled rider would never notice. either way they are two of the best sleds on the planet.

call and talk to shain, you will get some really good advice from him. My opinion is you would probably like the 8 better, just because of the weight. On the other hand I ride a 1000 and the extra weight does not bother me at all.

I'm big 1000 fan, I'm on number 3 now & very happy with them. That said, the power that we've got with a couple gallons of race gas is hard to complain about & the det sensor on the 8 is a nice safety feature if you're the type that likes to keep turning things up.

I've never ridden Shain's PG1000, so I may change my opinion if I ever get to ride one!!

The PG Twisted M1000 feels smooth and is a very friendly boondocking sled, its shakes more then the M8, if you can deal with the vibs its the sled to have and will totally hang with a RG M8....understand the M1000 needs an additional engine mount.

-Would you exchange weight for reliability? Or vice versa? Why?

I have an M8, but would love to have an M1000 on the big hill days

-I understand the trade-off is reliability vs horsepower. With what I've stated above, what is the boost "sweet spot" that I should set given my mechanical ineptuted?

Yes the 1000 has had some problems and the M8 is proven, so its your call if you want the bigger power or a sled that will last longer. Most will say the sweet spot for a Pump 1000 is 5 lbs, and the M8 RG is 12ish lbs. Im running 14ish lbs this year as my 1400 miles top end looks near perfect with 112 octane and redline syn oil

The M1000 is a great boodocker. I was never concerned about the weight difference and as a matter of fact I was partial to the M10 because of the power difference. The M10 has no problems keeping up in the boondocking department. I wouldn't be concerned about the weight difference you'll get used to it in no time you don't have to be a big guy to throw the 1000 around
-Would you exchange weight for reliability? Or vice versa? Why?
I can't really say anything about this because both of the sleds I have had were reliable
-I understand the trade-off is reliability vs horsepower. With what I've stated above, what is the boost "sweet spot" that I should set given my mechanical ineptuted?
I think that the boost sweet spot on the M1000 was at about 11lbs., but I never did turn it down below that. I did have the M1000 turned up to 15lbs. and it did have a noticable power difference, but I didn't run it for very long at that boost. On the M800 I ran it from 10lbs-15lbs. and the power difference was very noticable I ran it at 10lbs for over 1000 miles with no problems, but 15lbs. is much better. I am just going to say that 10lbs. is the sweet spot because you have enough power and you don't have to run the 114 and above fuel like you do to be safe at a higher boost pressure
-What would you do if you were in my shoes? Go with a different sled? Different Turbo? Go in another direction completely? Why?

I ride the same elevation that you do so if I were in your shoes I would go with the M1000. It gives you the opportunity to go from pump gas to say 15lbs. reliably(for me anyways/my experience). Then once you get used to the power you have the ability to even get more crazy and go with the 1200 turbo without changing sleds. Understand that no matter what you go with you could have problems be it a stock sled or a high boosting beast of a sled. I have had both sleds apart and neither showed any evidence of detination(M1000/600miles - M800/1400miles approximately).

I put 2400 miles on a Turbo Apex at boost levels as high as 22psi. I have ridden a P/G M1000, had good power for only 5 pounds of boost but the throttle response was not great. I built a P/G M8 at the end of the season, put 600 miles on it in 6 weeks. I rode it mostly at 8-9 pounds of boost. The sled was as trouble free as a stock sled. The throttle response is incredible, I've let many people ride it and every one of them say the same thing, there's no turbo lag. If you boondock 80% of the time, I think you would be most happy with an M8 P/G. If you were hill climbing 80% of the time, go with the 1000 or even better the 1200 kit.
The P/G M8 that I have has been the funnest sled I have ever owned for all conditions. I would highly recommend Boondockers P/G kit if you go with the M8. Easy install, good fit and finish, and most importantly the best fuel controller on the market. IMO

Just what I wanted to hear.

You guy's Rock! I really appreciate all the insight and perspective, thanks for taking the time to reply.

It's encouraging to hear such positive things about these sleds. Both from a maintenance and performance point of view. I really have been waffling on the turbo because of MY mechanical issues, but after reading the posts here I think I will go ahead and pull the throttle and get one.

Anybody know where I can get the best deal on 09 M8 or M10?

Good thread

Lots of good input guys thanx. Theres alot of people on the fence about boost, good to see quality answers. Not bashing

the 2 stroke turbo has definetly turned the corner over the last 2 years as far as reliabilitly. i think the performance has always been there but efi has made it far safer than back in the aerodyne days. (polaris 700 and cat 580 turbos for me) now every ride i dont think twice about it having boost because it has been stone reliable for over 3000 miles. i never adjust anything, last year it never saw anything but straight maverick 91 as far as the m1000 shaking at idle. its all in the "bob wieght" the 1000 has a huge bore and a longish stroke. what you have to do to an engine that lives at high RPM is do what we in the race engine world is an "over ballance" which simply means the counter wieght on the crank is heavier than the bob wieght . at idle and low RPM that shows its self as a shake because everything is out of ballance at low engine speeds but as the rpm comes up the bob wieght gets heavier through enursha and the engine becomes ballanced. back in the big cat triple days cat built them with a balance shaft that help with the shake..... but we removed them anyway.

I have been on both but own a M1000 PG turbo. The M8s were both 153 tracks, which I can move around almost too easy. I'm big man and for me I like having that little extra contact patch of a 162 to hold a sidehill with or quick power turns in the trees. As for weight, I didn't notice a difference once you are on boost. Both are great. I run at 6 psi.
